Re: from my experiance: I wouldn't recommend ati
Erez, The latest versions of Ubuntu, as well as Fedora and OpenSuSE 11.x use the latest Xorg server which *does not* need the /etc/xorg.conf file. Everything regarding the card is being done automatically (probing etc), so when you install Fedora 10 for example, you won't find this file. I assume that ATI tools do try to find this file, do a bit of parsing and modifying it. Since its not there, I suggest you re-create it with your distribution specific tools. X --configure creates a really messy file. Try to create a file with a settings for the open source driver, and then feed this to the atitool. It's really not the sweatiest land here in NVidia world. I'm using a Windows XP machine here for some tests with Geforce 8500 1GB RAM and I'm testing some VMWare stuff. I spent a whole day to find something which is so simple with ATI: When a program sits on another non-primary monitor, when you make it full screen, it should be full screen on *that* monitor (VMWare full screen, not maximized window) and *not* on primary monitor. ATI have this function working for years in windows and guess what? not possible in NVidia's twinview mode. You can use the nView crappy stuff, but still vmware insists open full screen on primary monitor. So it really depends who develops your Linux driver. nVidia, Although not opening their driver's source code, is really trying to put any feature that their cards have to be supported under Linux. CUDA, PurePlay, Twinview etc - all suported under Linux these days with 1 driver and easy install. ATI - a total nightmare on Linux, specially for the latest distributions.

[Snipped] so i say again. i wouldn't recomend buying from ATI. from now on. no ati neither amd for me. (with nvidia i used twinview and tv-out. i hope the opensource ati driver supports this ...) My experience with ATI and Nvidia cannot be more different than yours. With my old Nvidia GeForce 4 MX card, I had frequent crashes or hangups with the proprietary driver. Then when I tried nouveau which is the truly open-source driver (the nv driver is written in hex), the screen would freeze when switching to the virtual console, etc. and I still didn't have 3-D. Furthermore, the GeForce 4 was the lowest card to be supported by the proprietary nvidia driver, and it is possible they have droppped support for it afterwards or are going to soon. After that card's fan died, I decided to replace it with an ATI card and bought an AGP ATI Radeon HD 2600 card. My Mandriva Cooker system detected it right after reboot (although used a 16-bit bpp instead of 24-bit which I had to fix), and I've been happily using the open-source RadeonHD drivers ever since. Now I can switch to virtual consoles and everything works without crashes. I still don't have usable 3-D acceleration (for this I need the proprietary fglrx drivers), but it should be supported soon in FOSS, because ATI released specifications for that (as opposed to Nvidia), and there's a team working on the FOSS drivers. I blogged about my ATI card here: http://community.livejournal.com/shlomif_tech/12324.html I should note, however, that I asked the RadeonHD IRC channel and mailing list for guidelines on how I can help in its development and didn't receive any good reply.

is openmoko (hardware) really the solution ?
first, i refer to the idea of using a special hardware - the freerunner. when i first heard of openmoko - the first open phone, i was very happy. once and for all i can do whatever i like with my phone, not what nokia/orange/whatever wants me to do ... however, i never got to get one (1972/freerunner)- it wasn't sold in israel, it was not cheep, but the real killer - it was technologically outdated i have a nokia phone (N95 8GB). it is closed source, but still i can call using voip over wlan. i have a camera (5MP), i have 3.5G data connection. from experiance i know i'll only carry one phone with me even if i promise to carry both ... i can't take (good) pictures (or motion pictures) with it. also one thing i wanted an open phone was to use voip over cellular data connection - i can't with (1972/freerunner) as gprs has too a big latency .. in the end i didn't jump on the moko train it is open, but (currently) crippled by hardware and coming to think of it, linux didn't catch up by running on dedicated hardware - we do not use a linux specific display adapter neither linux specific processor or bus. what was good about linux, is that it runs on everything (almost) ... the way i feel openmoko can catch up, is if it is made to run on the latest phone hardware - (nokia N95 would be my choise), but any modern phone will do. i know the regular problems - hardware supports, documents, and a lot of which have much to loose ... this time the cellular carriers / manufacturers take the place of the villain which was formerally reserved for microsoft's (because they have a lot to loose) this seems like linux hardware support problem all over again ... just my 2c erez.

Dotan Shavit wrote: Please note that passwords are not transferred automatically from /etc/passwd to the new /etc/samba/smbpasswd file. After running mksmbpasswd all accounts are disabled so the system administrator must run smbpasswd for each account that needs to be enable. I'll expand on that. The passwords on both Linux/Unix and on Windows are stored encrypted. The reason I am using the quotes is that the technical term is not really encryption (a reversible operation given the right key), but rather cryptographic hashing, or one way function. Given a password, it is easy to calculate its hash (and thus, find out whether it is the same password as was given the last time), but given just the hash it is not possible to figure out the actual password. Now here's the catch - /etc/shadow and smb use a different hash function for storing passwords. In other words, the same password entered as both a Unix password and a Samba password will end up generating different hashed values. What Josh was asking for is, therefor, impossible. Writing such a tool would entail reversing the Unix password hash, which is something we would like to think is not possible.

Hi Jason, For a fellow Penn State postdoc (I was there in 1995) let me offer a variant of Omer's solution with some enhancements and a bit simpler syntax (works with GNU make, I assume this is the case as it is a Linux list): ## # list directories where files to be fixed live VPATH := /long/ugly/path:/some/other/path/too # list all files to be fixed here ORIG := figure1.eps figure2.eps FIXED := $(ORIG:.eps=_fixed.eps) # you can override this if eps2eps lives in a # different place from default FIX := /usr/bin/eps2eps fix:$(FIXED) %_fixed.eps: %.eps ifdef HERE $(FIX) $ $@ else $(FIX) $ $(dir $)$@ endif PHONY: fix ### With this, simple make fix will put each fixed file in the same directory with the original, while make fix HERE=yes will collect the fixed files in the current directory.
