What I would like to know is: if for whatever reason NVIDIA stop supporting the Linux drivers, will I be SOL and stuck with an unaccelerated card? Or is there a viable Free alternative that will provide at least some acceleration? (There is this: http://nouveau.freedesktop.org/wiki/ --- anyone tried it?) What about emulating the GPU in software (assuming a fast dual-core CPU)? I have been using NVIDIA video cards for awhile now in Linux. The proprietary driver works very well and is the same for all GeForce cards since 5000 series. I think most distributions have good support for the drivers as well. The only drawback, as you mention, is that the driver is not open. However, I think the benefit to risk ratio is high, and therefore I continue to use them. ___ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech

[vox-tech] mouse is too fast
I've got a ps/2 mouse on a desktop that makes the pointer move too quickly in Linux: the pointer moves too far for a corresponding physical movement of the mouse. I've turned acceleration off, and it is still too fast. By googling, I've found two things to try. The first is to set the mouse resolution in the X11 config file, like Option "Resolution""256" However, this does not make any difference for me. I read that this used to work before X11 version 4 (and Xorg-X11), but not anymore. The other recommended method is to set the acceleration to a fractional value, e.g. $ xset m 1/2 1 This doesn't do anything on my computer either. It seems the lowest the actual acceleration will be is 1/1, even though "xet q" displays the fractional value I entered. Any ideas? It seems someone would have fixed this obviously buggy feature by now, but apparently not! FWIW, the mouse moves at what feels to be the correct rate in Windows on the same computer, at about half the speed it moves in Linux.

[vox-tech] more adventures with power supplies
In my haste to replace my blown computer (http://lugod.org/mailinglists/archives/vox-tech/2007-01/msg00045.html), I bought a no-frills Compaq desktop (Presario SR1917CL) for cheap. I also wanted a Nvidia graphics card to play some games, and chose the PNY GeForce 7600 GS, mainly because it seemed to have the highest performance to power use ratio. The box spec'd a 300 W PSU minimum for the single card. This is what the PC had, and so I thought I would be OK. Although PSU total wattage suggestions of many high-end Nvidia cards aren't too bad (400-500 W) many have 12 V requirements of 20 A or even much higher. Browsing at Frys, I had a hard time finding any reasonably priced PSU that gave more than 18 or 19 A on the 12 V power channel. I plugged in the graphics card, and everything seemed to be working great, at least in Windows. While installing Linux (Gentoo), however, the SATA hard drive would very occasionally stop communicating. This made me concerned, but memory testing and various hard drive tests all passed. Now the most interesting part: my self-built kernel, without an initrd, would not boot, no matter what I tried! The auto-generated kernel with an initrd would boot OK. Again, the graphics card was operating flawlessly, now in Linux. Finally, suspecting inadequate power, I pulled the graphics card. Sure enough, the hard drive issues went away, and even my self-built kernel would boot! I thought this was quite interesting; somehow the hard drive power needed when booting without an initrd was enough to cause a failure. I immediately went out and bought a better power supply (Antec 650 W, 19 A on the 12 V loop), and everything is working together just fine now. Hopefully this will help and warn some of you about power requirements of Nvidia graphics cards. While it is tempting to get the latest and greatest card, beware of the cost of replacing your power supply too!

[vox-tech] blown power supply = fried MB and HDs
I went to turn on my 3 yr old custom built desktop on Friday, there was a load "crack" sound, and the computer would not boot. After spinning the dvd drives, it would immediately reboot; no bios display or anything, even after clearing cmos and unplugging all the drives. I eventually traced it to a blown capacitor in the power supply. I went and bought a new power supply, installed it, and got the same behavior. OK, the motherboard is fried; went back out and bought a whole new computer. I installed my old hard drive to find that it is fried too! Now I am really unhappy: several years of photos, game data, personal files are all gone! :-( In a confluence of bad timing, you may recall about a month ago that my hard drive was acting up (in hindsight, maybe related to a failing power supply). So I installed the hard drive I had been using to for a backup. I hadn't got around to establishing a new backup procedure yet, but I was going to over the weekend, honest! I thought if the drive were to go bad, I would get some warning. I've learned several lessons from this: do not build a computer from cheap parts and especially do not use power supplies with the "raidmax" brand. Do not go more than 24 hours without having some form of a backup. If part of a system is acting funny, the whole thing may blow without warning.

[vox-tech] failing hard drive...
It looks like I have a failing hard drive. I've never experienced this before; I guess I have been lucky. The hard drive is a 160 GB Maxtor ATA drive purchased and installed in a custom built desktop pc a few years ago (2003?). The first partition is NTFS with winXP installed. I have several more partitions for Linux and data (reiserfs and FAT32). Only the NTFS partition is experiencing problems at the moment. Windows no longer boots. Using the repair console of the windows installation disk, a chkdsk /r reports "unrecoverable errors". Not trusting windows tools, I ran Maxtor's PowerMax self-booting utility. An advanced scan reports "device is failing" with not much more information. File system checks of all the other partitions report no errors. So I must have bad sectors somewhere in the physical region of the first partition. Will this problem get worse and propagate to my other partitions? I see several non-free programs on the web that advertise recovery of bad sectors. Does anyone know about these? I'm not about to drop $50 for software that /might/ fix my drive when I can go buy a replacement drive for $50. So my last question(s): any recommendations for a replacement drive? Are Maxtor drives considered "low end"? I'm stuck with PATA since my motherboard does not have SATA. I bought it just before that technology became standard.

Re: [vox-tech] dual-boot machine / vmware / SATA drives...
short: You can run a virtual machine via VMWare using a raw drive on SATA. long: I have a laptop with a SATA drive. The first partition is NTFS running corporate windows xp. Later partitions are for gentoo Linux. I have a dual-boot setup using grub. Inside Linux I run a VMWare virtual machine which accesses the NTFS raw partition. When I boot the virtual machine, I see my entire grub menu as if I were booting the computer itself. I just make sure I choose windows then, although if I accidentally choose Linux, I simply get an error. In windows I have two "device profiles" one called "real" and one called "virtual". I choose virtual when I am running the virtual machine, of course. When I set this all up, I remember I had to manually hack one of the vmware config files to make the SATA work. You can find the info in the vmware forums, I think. The other problem that came up was the windows xp authorization: it may think you have installed it twice due to the greatly different device profiles. Once I managed to get around that, it hasn't bothered me since. Now everything works seamlessly except for some occasional networking issues. Hope some of this helps.

Re: [vox-tech] PNG tweaking - how to 'kill' RGB in 100% transparent pixels
Have you looked at ImageMagick's "convert" utility? It is a fairly powerful tool with many options. As a brute-force method, converting to some format that doesn't support transparency, and then back again, might work for you. Jonathan Bill Kendrick wrote: So I've got 355-and-counting PNG images in Tux Paint's 'stamps' collection. Many of these were photos which were resized, and had the backgrounds removed (using the Eraser and selection tools in The GIMP), and then saved as RGBA PNG files. By default, I GIMP saves PNGs with the following option set: "Save color values from transparent pixels." This is nice for editing later, since you can use the Eraser tool in 'Anti-erase' mode, to bring those pixels page. (In other words, when erasing, Gimp doesn't touch the RGB channels, just the Alpha channel. A solid erase simply makes Alpha 0. Anti-erase brings it back to 255.) However, this is NOT nice when you no longer care about the erased pixels, as it just ends up being wasted space in the PNG. By that I mean the PNG compression is wasting its time and energy (and disk space) worrying about the RGB channels of pixels which are 100% transparent. If it were a solid color, it would compress a lot more. (I believe Gimp uses its, or the PNG's, "background" color when you uncheck the "Save color values from transparent pixels" option.) While I could simply load up all 355 PNGs into The GIMP and resave them one by one -- making sure the "Save color values..." is unchecked -- that would take a long time. Additionally, since the project is growing, and I don't really feel like keeping track of which PNGs are "golden", I was hoping to make a script that I could run on occasion (say, before release, or after adding a batch of new PNGs). My initial thought was to use "pngcrush." I have one immediate problem. Debian/sid's pngcrush is currently b0rked: Warning: versions are different between png.h and png.c png.h version: 1.2.7 png.c version: 1.2.8 [...] pngcrush: relocation error: pngcrush: symbol png_read_data, version PNG12_0 not defined in file libpng12.so.0 with link time reference Worse, though, is that "pngcrush" on a Debian/stable machine I have access to doesn't seem to actually remove the 100% transparent pixels, nor do I see any obvious means by which to do so. (The best crushing I get on "stamps/animals/birds/ostrich.png" is 0.17%, if I recall correctly.) NetPBM is pretty useless to me for this problem, since the PPM format doesn't support Alpha -- it's only RGB. ImageMagick's "convert" didn't seem useful, either. Aside from writing my own C app that loads a PNG and then rewrites it (altering the RGB to some solid color for every 100% transparent pixel), does anyone out here have any suggestions? (I'm not against writing my own C app, but... if it's been done already, why bother? ;^) ) Thanks!!! ___ vox-tech mailing list vox-tech@lists.lugod.org http://lists.lugod.org/mailman/listinfo/vox-tech

So, I always have X running with xterm anyway; might as well take advantage of it. i've never really used cygwin before. how exactly is X supposed to work? i've run 'startx' just because i didn't know what else to do. got something that looked like an xterm and was able to run cygwin's gvim from that. but it seems ... very unsatisfying. is there a way to just let cygwin take over the entire window? how do you have your cygwin/windows environment set up? i'd like to emulate someone's setup who has something comfortable. don't have the luxury anymore for massive experimentation like i used to. I recently started trying to use cygwin myself. While Googling I noticed a lot of recommendations to use the rxvt terminal. It seems fine, like xterm but with a sidescroller bar. I also discovered that X and an x-based terminal can be started immediately by running: cygwin\usr\X11R6\bin\startxwin.bat I edited this file to start the rxvt terminal rather xterm. This is now what I execute whenever I want to use cygwin now. I quickly get an rxvt terminal that can launch x-apps if desired. I did read that you can start X in such a way that you get a big X window that takes up the screen. I don't have much use for this myself.

[vox-tech] linux, lotus notes, palm os handheld
I just started a full-time job as a scientist/engineer at a very large international company. For networking and personal computers, "everyone gets the same thing" and "everyone does the same thing". This means Dell, Windows, Lotus Notes, and no alternatives. I didn't even get admin privs on my laptop until I filed appropriate paperwork! Anyway, I quickly dual-booted the laptop so that I have a choice between the corporate windows and Gentoo Linux. But in order to use Linux on a day-to-day basis, I must be able to access my email and calender via the Lotus Notes system. Also, I am dependent on my PDA (palm os), which I will need to sync with Lotus Notes or equivalent. So here are the two scenarios I can think of: A) Install Lotus Notes in Linux via CrossOver Office. Lotus Notes is rated "silver", so this should work for the most part. However, it is unlikely that communicating with a PDA would ever work with a CrossOver Office installed application. B) Use native Linux email/calendering software such as Evolution or Kontact. These will sync with PDAs, but how do I access the Lotus Notes data on my company servers? Does anyone know if Lotus Notes uses standard network protocols (pop3, smtp, M$ exchange) or if it is "proprietary"? So, I would love to hear suggestions, experiences, etc. If I can't make something work, I am afraid I will end up using windows at work 90% of the time, if not more!

Re: [vox-tech] linear algebra: equivalent matrices
Hi Pete; nice to see you on the list again.
Peter Jay Salzman wrote:
Posted to vox-tech since this is a CS topic. I'd like to verify some things
which I think are true.
Consider the set of all square matrices of rank n. The determinant of M,
det(M), forms an equivalence class on that set. The equivalence relation is
defined by:
A ~ B iff det(A) == det(B)(1)
Now, like vectors, matrices are always expressed in a basis, whether we
explicitly say so or not. So when we write the components M, we should
really write M_b where b represents the basis we chose to express M in. We
can express M_b in a different basis, say M_a, by a rotation operation:
M_a = S^{-1} M_b S
where S is an orthogonal "rotation matrix". However, no matter what basis
we express M in, det(M) remains constant. Therefore, we get an equivalence
class on the set of square matrices of rank n based on whether we can rotate
one matrix into another. The equivalence relation is defined by:
A ~ B iff A = S^{-1} M_b S(2)
Did you write this equation correctly? I would expect something like
M_a ~ M_b iff M_a = S^{-1} M_b S
for _some_ orthogonal matrix S, which determines the basis for M. There is
one rotation matrix S that will make M_b diagonal. That rotation matrix is
formed by the eigenvectors of M_b.
Big finale:
The equivalence classes defined by relation (1) are epimorphic to the
equivalence classes defined by relation (2). If we place a restriction on S
that it must have a determinant of +1 ("proper" rotations), then the two
sets of equivalence classes are isomorphic.
What this is really saying is that, when viewed as the sides of a
parallelopiped, a matrix will always have the same area no matter what basis
you choose to express it in.
How accurate is all this? In interested in the lingo as well as the ideas.
Looks fine to me. In my PhD work (almost done!) I deal with 2nd order
tensors for continuum mechanics theory. I've actually had to specify
and use rotation matrices explicitly in some of my numerical methods.
Jonathan
Thx!
Pete
PS- Whether a rotation is S^{-1} M_b S or S M_b S^{-1} depends on how your
favorite linear algebra author defines his/her rotation matrices.

My specific question was whether, during the Fedora upgrade, everything seemed to go OK, that there were no error messages during the upgrade process. To start windows, I have the bios boot from hdd0. Booting from hdd1 gets me a grub window. Hdd2 is a disk boot failure, and SCSI gives me windows. I think you are going about things incorrectly. You shouldn't need to go into BIOS to do anything! The windows does not give me a boot menu, though I tried to set one up at every chance I had. There are a lot of partitions, one reason being I wish to save the existing home file, on the hdc hard-drive. I am considering swapping the master/slave hard drives, leave the slave off, and set up linux on the new master. (There is nothing to save there). Again, I think this is the cause of your trouble. You shouldn't be swapping hard drives around. The first partition on the master drive should be windows. Linux can be anywhere else. The Linux install should have replaced the boot loader on the master boot record (MBR) of the master drive. From what you are saying, it seems that this is the missing piece. Grub can be re-installed on the MBR if you are careful and know what you are doing.

To make matters more confused, at other boot times, Debian ignores the FireWire port and gives the network jack ETH0 and an IP.

Re: [vox-tech] tell gnuplot to use a single X11 window

Hi everyone,
is there any good way to get gnuplot to send its output to a single window,
such that any successive plots update an existing X11 window?
i have looked over the gnuplot man page, and can't seem to find what i am
looking for.
while it is a little ridiculous, i like to keep track of my progress while
writting with this little script:
while `true`; do wc -w main.tex | awk '{print $1}' >> word_count ;\
echo "set ylab 'words'; set xlab 'minutes'; \
plot 'word_count' with lines notitle" | gnuplot -persist;\
sleep 60; done
this produces a nice little graph updated once a minute. however, gnuplot on
linux produces a new window with every plot. on OSX it is possible to keep
all output in a single window* .
* there is a bit of a difference on OSX, as an application called AquaTerm is
being used to render the output, not X11.
any ideas on how to do this with regular X11?
thanks!
I had the same problem. My fix was to write a small perl script to wrap
around gnuplot.
The script writes a small gnuplot script and then invokes gnuplot with the
script.
When it comes time for a new plot, the script rewrites the gnuplot script,
kills all instances of gnuplot, and re-runs gnuplot with the new gnuplot
script.
It works surprisingly well.

It creates a "movie" of the time evolution of a quantum wavefunction. Very
cool.
Are either of you familiar with octave (www.octave.org)? It is
essentially a high level numerical programming language. It uses
gnuplot as it's primary plotting interface and, by default, plots
everything in the same window. You could probably write your scripts in
octave if you were interested in doing so.

Re: [vox-tech] Install windows in linux Red Hat Enterprise
Stanley I'm sorry you didn't get everything solved at the Installfest. If you must use Peachtree, it does look you will need to run Windows. While the other two responses are correct and helpful, for beginner users of Linux I am going to recommend a brute force method: 1) back up your data 2) boot the windows install CD 3) delete all partitions on your hard drive 4) make a single partition for windows (~10GB) 5) install windows on that partition 6) install linux on another 10GB, leaving some unpartitioned space if possible 7) make another partition that is formated fat32; this can be used by both windows and linux It is a shame you have to delete your existing linux with this method. However, trying to work around it while installing windows could lead to all sorts of trouble that could take a long time to resolve.

But it just dawned on me that while I have set up dual boot systems several times in the past, it has always been with Windows 98.

Should you need to reduce the winXP partition non-destructively (usually you do), you'll need partitioning software that handles NTFS. Also, Linux cannot (easily) write to NTFS, so you'll want to make a separate FAT32 partition for sharing files between windows and Linux.

Re: [vox-tech] Rant: LaTeX graphics programs

Sure thing, but I have to warn you -- these aren't the most complicated
diagrams in the world. That's partially why I got used to writing my own

interface.
Here's three documents that should show a nice cross section of the type of

http://www.dirac.org/Green-Functions.ps
If you have any suggestions, I'd definitely be appreciative.
One of my problems with xfig and dia is that I haven't figured out how to
put mathematics in my diagrams. Something like:
\put(50,65){$\vec{F} = \fder{p}{t}$}
which would be trivial when drawing my own diagrams. I suppose I could
insert it in the .eepic file that xfig generates, but the whole point is to
try to do this in a wysiwyg manner.
Even if it means just clicking on the screen to open up a box and type the
equation myself (which is what I'd prefer --- I'm light years faster doing
typeset math than any human being can be using a lyx/MS Word equation
editor.)
I only see a figure in damped.ps (using gv); looks nice.
Anyway, the ability to put latex typeset labels on my figures is
precisely the reason I use xfig and not some other program (like
Inkscape). Again, there are a few different ways to proceed. My
current method is to type latex commands in text boxes in my xfig
figure. I make sure to choose "latex fonts" (not postscript fonts;
there is a box to choose), and I have the "special" flag checked. This
part is in the manual:
http://www.xfig.org/userman/frm_miscellaneous.html
As the manual suggests, you can then export this as ps/latex, both
parts. I used to do that. Instead, I now use the program "fig2ps"
found here:
http://sourceforge.net/projects/fig2ps/
This converts the fig file directly to ps/eps/pdf with all latex
commands processed beautifully! You can even use a latex header file
with personal commands defined, e.g. I redefine the /vec command. It's
not quite wysiwyg; the latex commands often take up more space than the
final text output, so sometimes it takes a little trial and error to get
correct placement. Still, it works great for me.

It seems that you want figures to be a Latex picture that you input. One possibility is to make an eps with some other program (Dia?), convert to xfig with 'pstoedit', and then convert the xfig to Latex picture.

To start with, DPI (dots per inch) implies that each pixel has a physical size, 1/72 of an inch or whatever. As far as I know, JPEG images have a size in pixels (e.g. 106 by 64 pixels for the watertower image on the LUGOD home page), but the pixels have no inherent physical size. Something outside of the image--probably the software used to embed the image into the document--is deciding how large the image should appear on the page. I would expect that you can adjust that, ie tell the software how large to print the image or what DPI to use. JPEG files include DPI as metadata, which is used by some programs. I suspect it would be fairly trivial to write a program that changes this. Yes, the print resolution is definately withing the JPEG file, thoughsince the programs like Gimp and PDFTeX that understand print resolution as distinct from pixel resolution do not have access to any other metadata beyond that in the file itself.

Re: [vox-tech] GUI for Camera on Sarge?
Bob I think you are on the right track. I've noticed also with Fedora that it automatically edits /etc/fstab when usb storage devices are attached or removed (cameras sometimes behave as storage devices). I'm not sure what daemon does this, but I don't think it is submount. It might be something called "HAL" that was mentioned previously on this list. A simpler thing to do is just add the right line to /etc/fstab permanently, yourself. Then you can have an icon on your KDE desktop to mount/unmout the device (/dev/sda1). You will, however, need the correct options, including "user(s)" which allows non-root users to mount. Jonathan Bob Scofield wrote: I had some questions arising out of my effort to set Sarge up like SuSE, which allows me to drag and drop pictures from a digital camera to my hard drive. On SuSE I just go to the My Computer icon, and click on an icon for a USB disk. This all happens in the Konqueror web browser. A few weeks ago Bill gave Pete directions on how to set up the My Computer icon on KDE. I've followed those directions, but have been unsuccessful in getting an icon that will give me a GUI access to the camera. The first problems I encountered were permissions problems; e.g. "Only root can mount /dev/sda1 on /media/camera." I still haven't solved these problems. It's confusing because /dev/sda1 seems to have the same permissions on SuSE and Debian. But I have become interested in the following issue. One error message is something like "/dev/sda1 is not found in fstab or mtab." In SuSE the following entry automatically appears in mtab any time that the camera is plugged into the usb port: "/dev/sda1 /media/usb-0039731344:0:0:0p1 subfs rw,no exec,nodev,sync,procuid,iocharset=utf8 0 0." In my cheesy way, I began putting variations of this entry into my Sarge fstab. I got different error messages, but became interested in the one that said that the Sarge kernel had no support for subfs. After Googling, I came across this website: http://submount.sourceforge.net/ I am starting to think that SuSE is automatically mounting the usb port when the camera is attached because of "Submount." The web site claims that Sarge is one of the distros that has a binary form of Submount available. But I can't find such a package on the Debian website. So here are my questions: 1) Do people agree that it's Submount that is allowing SuSE to automatically mount the usb port when the camera is plugged into the computer? 2) Does anybody know if Sarge has a Submount package that can be gotten with apt-get? 3) Is anybody dragging and dropping camera photos from the camera to the computer on Debian? If so, how do you set this up? I may be back later for the permissions issues. Thanks.

"named" with the command:

my intent was to get citations that look like (author, year) ... the
"named" style was the closest that I could get, however the citations
end up looking like [author, year] ...
Did you try "apalike"? That's a standard one. There are many styles
available, but finding the right one can be difficult. Unless it is a
requirement, numbered references are much prefered over author-date.
any ideas on how to get the more traditional (author, year) style?
thanks!
PS: for anyone using macos X there is a great application called
"Bibdesk" which can help manage your .bib file. Anyone know of a similar
tool for Linux?
I use pybliographer, but there are many other bib management programs
available.

At that level, either your kung-fu is good enough of you hire a professional staff to take care of your IT. Oh, I agree with you. Most of us want to have ssh ability. I'm thinking of all the newbies I help install linux for who have no idea that a remote login is even possible. Then they complain about having to use root all the time, and they change the root password to something silly, like "root". Then they get hacked through ssh and exclaim "I thought you said Linux was secure!" I think that if you want ssh, you will know what it is and will know to enable it.

Re: [vox-tech] Spyware For Linux?
It is clear that Linux doesn't have a spyware or virus problem. I've been wondering, though, about the frequency of compromised Linux systems of home users. By compromised, I mean an someone's entered illegally through a backdoor and is running whatever they want. Occasionally I hear of it happening with power Linux users running all kinds of internet services, but does it happen with home users? Can it happen if they don't use any network daemons? It bothers me that Fedora turns sshd on by default. A naive user could set a silly root password, and they'll be cracked in a few hours. I kind of watch Gentoo security announcements. Many of them deal with denial of service (DOS) attacks where a program running as nonroot could hang the computer. How often does this happen? I'm less concerned about this one because I would notice right away and fix it. A comprised system can go undetected for awhile and mean lots of clean up work. Jonathan Mark K.

(See the screenshots at the URL above.) -bill! As long as you bring up KDE, I have a couple of questions. I've been using KDE for a day now, and I can't figure out a few things: 1. I want a desktop icon similar to "My Computer" that has shortcuts to various filesystems like /usr/local, /home, /C, /D, etc. How can I generate such a thing? Konqueror, as a filesystem, may do nearly what you want, as is. Do you have a "home" icon on your desktop or in your kmenu? By default, this just brings you to your home directory. You can point konqueror anywhere you want, and then save "view profile" under settings. Also, on the side bar is a number of icons that show links to different places. One is "devices" which shows links do different mountpoints. Another is "root filesystem", which shows "/", of course. You could make a directory with symlinks to whatever you want, and have konqueror startup there. 2. How do I change the font displayed underneath icons? The standard KDE font, aside from not being my cup of tea, is too big for my liking. If you are not yet familiar with KDE's control center, check it out. You can adjust most KDE fonts there. Also, the fonts for part of konqueror can be changed in konqueror by "configure konqueror" from the settings menu. 3. How do I get "sloppy focus"? Sloppy focus is like Unix focus: when the cursor goes over a window, the window gains focus. However, in Unix focus, when the cursor leaves the window (without hovering over another window), the window loses focus. In sloppy focus, when the cursor leaves the window (without hovering over a new window) the window *remains* focused. This allows me to keep a window's focus *and* click on the desktop. dunno this one 4. I hate to ask this, maybe embarrased is a better word, but is it possible to use MS Windows 95 icons in KDE? The default KDE icons are too fancy. I want something less ornate. Less busy. I really loved the icons (and widgets) that came with MS Windows 95. Is it possible to use those icons in KDE? You can choose different icon sets in the control center. You can install more icon sets using your distribution or directly from http://kdelook.org/. 5. Is it possible to configure artsd to become a client of esd (the Enlightenment Sound Daemon) rather than trying to grab /dev/dsp directly? You can mess with how arts works in the control center (sounds & multimedia - sound system). I think this is an option, but it used to not work. Things are better since KDE 3.3. Better yet, is it possible to tell KDE applications to use esd instead of artsd? Possibly. In the control center under system notifications, you can specify which player to use. For awhile I used "aplay", i.e. alsa directly. Now I am back to using arts since aplay won't do .ogg and .mp3. Also, I really recommend using alsa with the "dmix" plugin (http://alsa.opensrc.org/index.php?page=DmixPlugin). This will help with sound mixing.

I've never gotten it work, probably because I am not using the right
combination of packages in LaTeX and export format in xfig (there are eight
export formats that appear to be LaTeX-related).
There are many ways to go about this:
1) You can just export a eps/pdf and include that directly, but this is
not convenient if you want to process latex math in the figure. You can
"replace" text in the figure with the 'psfrag' package, but I found that
cumbersome. This is probably the best (only?) option if you want to use
inkscape.
2) You can export ps/pdf with the text separate in a latex file
("combined ps/latex"). Then you input the latex file in your document,
which has its own includegraphics command. This works fairly well,
except that I like to have standalone pdfs I can look at.
3) What I've started doing recently is using a script called fig2ps

translates any latex text, and creates a standalone eps/pdf. This I
include in my latex document as usual.

Sodipodi didn't understand the arrows, but didn't mess with 'em, either. I just installed inkscape to check it out. It looks really nice; more inuitive editing than xfig.

Once Knoppix boots up, get a terminal, become root, and run "grub".

Re: [vox-tech] Intermittent Sound Issues under Fedora Core 2
While Linux can produce quality sound fairly easily, applications that
run on Linux do not like to share the sound. Your type of problem is
quite common and drove me crazy for a long time. I suspect that "arts"
(KDE's sound server) is competing with XMMS for the use of ALSA (actual
hardware sound driver). You probably want to enable the "dmix" plugin
for ALSA:
http://alsa.opensrc.org/index.php?page=DmixPlugin
This may not immediately solve your sound problem, but it is a step in
the right direction. I've found it necessary to configure "esound"
(another sound server) to use dmix, and then I use the esound plugin in
XMMS.
The only problem with sound mixing that I have now is
Mozilla/Firefox/Thunderbird hanging sound once in awhile. They also use
esound, BTW

My desktop system at work is Fedora Core 2 with a 2.6.5-1.358 stock

development work with xmms running so I can listen to music on my
headphones and tune out the ambient noise in the office.
However, at seemingly random intervals, always at the end of a song on
my xmms playlist, xmms stops playing and (ALSA? artsd?) generates this
dialog:
couldn't open audio
Please check that
your soundcard is configured properly
you have the correct output plugin selected
no sound program is blocking the soundcard
Sometimes there's an accompanyng alert tone, sometimes not. Xmms doesn't
crash... it just stops playing. When this happens, sometimes I
immediately try to click play again; other times I simply continue with
whatever I was doing until It's convenient to ctrl-tab over to xmms and
press play then. And, again, sometimes pressing play immediately starts
the music right up. But other times, the dialog re-asserts itself and I
get no joy.
Sometimes when this happens, I've selected a different xmms output
plugin, and other times I've just left it on ALSA. It seems to make no
difference in the behavior. And *always*, if I wait long enough, xmms
will allow me to continue listening. Sometimes after only one click of
the play button, sometimes not for ten minutes.
A quick search of Google Groups reveals nothing that seems to pertain;
RedHat's documentation doesn't cover this; I found a troubleshooting
script here:

The good thing is the options are still there, just not available through the preferences interface. There is an extension (the name of which I can't remember at the moment) that fixes that problem. Luckily you can always manually configure it. Try typing 'about:config' in the address bar. This brings up a page with every possible configuration option and their current value. You can then filter down to the mousewheel options by typing 'mousewheel' in the filter bar. There are probably 3 options you're particularly interested in here: mousewheel.withaltkey.action, mousewheel.withcontrolkey.action, mousewheel.withshiftkey.action. Each one of course modifying what happens when you use that particular key while scrolling the mousewheel. You can double click on any of them and change the value. Setting to 1 makes the mousewheel scroll a page at a time. 2 is to go forward and back in your history (equiv. to the forward/back buttons). 3 causes the wheel to increase or decrease the font size (very handy on some sites that set it way too small...I bind that to ctrl).

Re: [vox-tech] Sarge Printing Problem
There are two things that should be simple and standardized in linux, but definitely are not: sound and printing! Both are getting better if you know what to do... From my experience, cups is the way to go for printing. I highly recommend the web interface for configuring, testing, and troubleshooting. There are other guis available for running cups, but they don't always work correctly. The web interface is often the same across most distros and usually works. So if you haven't already, put localhost:631 in your browser's location bar. If the cups daemon is running, you should get a menu to start working CUPS. If you have a printer correctly installed, clicking on the "print test page" for that printer should give you a nice CUPS test page. Jonathan Robert G.

HTH, Jonathan Dylan Beaudette wrote: Hi everyone, I have a machine here that is starting to drive me crazy. It is a Compaq Pentiumm III class machine, with integrated everything, and a funky case. I have tried just about every flavor of linux, and only 1 (SUSE 9.1) would even install. Even after I installed it, any attempts by the OS to enable DMA access to one of the CDROMS led to a nasty crash. The CD drives function perfectly from windows, and in SUSE 9.1 when in it DMA mode...However, every linux install CD barfs about half way though the install process... The offending IDE controller is an Intel 82801AA. So it has come down to a couple options: 1. use windows, and put up with all the crap associated with it (obviously not ideal) 2. re-install SUSE 9.1 and put up with broken DVD playback (needs DMA) and funky sound 3. replace some of the hardware and install Debian / Yoper My question to the list is: Does anyone know where one can get a hold of some decent pentium III class hardware that I can use to put together a working machine. Ideally a mini Shuttle-type system would be ideal, but they seem to price out at about $400 minimum.

Re: [vox-tech] Slackware 10 Printing
Many HP Lasers work great with the standard postscript driver. However, you may need the hpijs driver for the HP4L. That's what I need for my HP4. Jonathan wild bill wrote: OK, I give up. I have been trying to set up my Slackware 10 box to print on my old HP 4L for over a month with no success. I got my wheel mouse to work, sound was another challenge, and getting 1024 x 768 took a while. But I am completely baffled with CUPS. I moved from SUSE which had YAST to handle many of the arcane sytax/usage problems that are probaby the root of my problem. The http://localhost:631/admin command to get to the gui apsfilter app is great BUT, what device url should I use for a workstation box? bill wells ___ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech ___ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech
Re: [vox-tech] Printing photos with KDE
I just looked at my CUPS web interface settings for an HP printer I have. "Photo/4x6" is a choice of page size for me. My guess is the printer driver you are using is lacking in this area. I'm not sure about a solution. Jonathan Rod Roark wrote: OK my wife has a Canon i860 printer on a Slackware 10.0 box. It's got a suitable CUPS printer driver installed and everything works great. Almost everything. Now she wants to print (borderless) photos on 4x6 photo paper. The printer came with a holder/feeder for the paper, but I don't know how to tell KDE or CUPS about the custom paper size (there's a handful of paper size choices, but 4x6 is not one of them), and/or what a suitable printing utility would be. Does anyone know how this is done?

Re: [vox-tech] simple backup and restore
I use rsync to keep the entire root filesystem of several computers identical. See this post: http://lugod.org/mailinglists/archives/vox-tech/2004-03/msg00252.html You could do similar to backup your entire root.

Re: [vox-tech] Histograms on GNU/Linux?
I use Octave for 99% of my numerical work lately (www.octave.org). It has functions to produce histogram/bar plots. By default it uses gnuplot as its external plotter. Jonathan Peter Jay Salzman wrote: I have a few numbers in OpenOffice that I'd like to make a histogram of. It appears that OO has no histogram plotter. Gnuplot doesn't seem to have one either (there appears to be a patch, but I'd rather not go down that road unless I have to). It appears that Gnumeric can do histograms, but when I tried...
