Re: Migrating RAID1 to new system

However, the RAID arrangement is proprietry and different to mdadm

No, I believe it's RAID5 - 8x240GB.


I thought you said earlier that it was managed with mdadm, so I took it 
to be a JBOD in the LSI controlled and a RAID5 in mdadm. 


I'm planning on replacing those disks with 4x1TB disks, which would
work on the onboard controllers. I still can't decide whether to
continue to use the LSI controller.


Your call. They're a bit more directly visible and manageable under 
mdadm. If you're not using the LSI controller then the drives can also 
be physically moved to a machine with no LSI controller should that 
become necessary (thinking DR here; but you've got backups?)



Actually, if I did use the onboard, I could use mdadm, take the system
down to perform the initial install, and sync the data from the LSI
disks while the system is running, then shut it down briefly to do the
final sync after the bulk of the data has transferred.


Yes, that would work I think. Which would migrate you off the LSI 
controller, yes? To pure mdadm with on board SATA?



The LSI stuff is pretty good in my experience. Ran them in several IBM
boxes and also at home for years.


I am inclined to believe it will perform better than mdadm.


It should. The OS sees one drive for the raidset and does one I/O for a 
write; the other I/O to the individual drives is done by the LSI 
controller.  If mdadm manages the RAID it must update each backend drive 
itself from the OS.


It doesn't change the underlying physical drive behaviour, but it moves 
managing the RAID and the writes requires out of the OS.

The important thing is to be able to monitor them. I've some scripts for
that - put them in a 5 minute cronjob. Or in your monitoring system eg
nagios. Then you will get timely emails if a problem occurs.


That sounds awesome. Do you know where I can find those scripts? I
forgot they used to be referred to as megaraid.


I've attached "mcli" and "nagios-report-mcli". "mcli" invokes the 
cs.app.megacli python module conveniently. The nagios script wraps mcli 
and produces a nagios compatible status line.



I wrote the cs.app.megacli Python module for this (see PyPI) and have
some small auxiliary scripts which wrap it.


Can you forward it on?


The module is here:

 https://pypi.org/project/cs.app.megacli/

It is Python 2 specific because historically it needed to run on the 
native Python of some RHEL4 and RHEL5 machines. I've a TODO to make a 
Python 3 version.


Install is "pip install cs.app.megacli". Or use the python file I've 
also attached.


This is dependent on the LSI MegaRAID Linux software. Which you used to 
be able to download, but I can't find a download for it any more. I can 
ship you an RPM or a tarball of the unpacked tree for x86_64 separately.  
The Python code expects this installed at /opt/MegaRAID.



I have another system on the same network with like 7TB of data
available. I'm thinking that I sync a copy of the user data to that
system, and create a virtual machine on that system with the mail
server config that somehow mounts the directory on the host system.


You could make a virtual drive for the VM in the usual way (distinct 
from the VM's OS virtual drive).  Copy to it via the VM. You could NFS 
mount the original system's volume to the VM and do a regular 
cp-then-rsync.



Disable the production system and change the IP of the virtual machine
to assume that of the mail server.


Maybe allocate a service IP for the mail system instead (just an extra 
IP _not_ officially assigned to a particular physical machine). _Add_ it 
to the original system well ahead of the move. Update DNS for the mail 
to point at the service address (hoping your clients use a logical name 
like "mail" or "smtp" etc, not the personal hostname of the mail 
system).  Wait for all connections to be using the service address.


When the new address is in play, sync your replacement VM. (Of course, 
get the copy and a mostly-sync underway while this is playing out.)



Users will then access this
temporary system while I rebuild the production system and transfer
back the data.


At cutover: down the mail services. Sync latest volume state to the VM 
(from the VM so that it can be root at the VM end). Drop the service 
address from the main machine, add it to the VM. Do final sync. Check 
things, then bring up mail services on the VM.



Once the initial bulk transfer has occurred, shut down services on the
virtual machine and sync the remaining user data back to the
production system.


Yep. And move the service address back.


Does this sound feasible?


I think so. I'd get it all dow

Not fundamentally.

OK.  I'm not sure what you think I'll learn by doing so.


Only that it is a shell script that handles the typically used boot options, 
but doesn't do anything else.


fsck.xfs exists because Linux's "fsck" supports multiple filesystems and 
Irix's did not.  On Irix, fsck was exclusively for EFS.  XFS used xfs_check 
and xfs_repair.  When XFS was ported to Linux, the tools were not renamed; 
instead fsck.xfs was put in place to direct users to the correct tool when 
they ran "fsck -t xfs".


And when they really need a repair that the XFS mount process doesn't 
accomplish.


None of that makes XFS immune to corruption, nor reduce the time or 
the memory required to fix an XFS filesystem if it's damaged.


Of course not, though I have the impression that the repair tool is less memory 
intensive than the ext4 equivalent.


"Never" is indeed not _literally_ true, but it is effectively true, 
far far far far more than is so with ext4. Ext4 really needs fsck 
after an unclean unmount, and it is not cheap for large filesystems.


With journaling and write barriers in place, I don't know any reason 
that ext4 would be any more affected by a power loss than XFS would 
be, and having had to perform recoveries on both, I don't find one to 
be significantly better than the other.


Fair enough. We may be into the realm where a question on an XFS list may be 
more illuminating about the modern state of play.


Thus, my advice remains that users should test both because they do 
differ in performance in different workloads.  If one will be faster 
under normal operation, 99.95% of the time, and require slightly more 
down time to recover in the other .05% of the time, then selecting the 
option which is superior 99.95% of the time is a perfectly rational 
thing to do.


That's especially true of backup systems where down time does not 
carry the same impact as down time in a production system does.


The two are like night and day in the recovery scenario (== xfs 
pretty much never needs manual recovery, and recover is very fast).


That seems subjective.  I've personally had to recover more XFS 
filesystems than I have ext4 filesystems, and I use ext4 filesystems more 
often.  My subjective experience is quite different than yours.


Apparently so. I've had very good experiences with XFS, and plan to stick with 
it at present.


Out of interest, how recent was your need to recover XFS, and what were the 
circumstances that caused it to be necessary?

The Fedora Server installation defaults to XFS. Workstation defaults to ext4.

For your use case either filesystem will work. Use what you are 
comfortable with. Both are stable, supported, and will give you full 
performance from your setup.


Use XFS. It is stable; never needs fsck. If ext4 needs to repair it will take 
days/weeks on a filesystem that size, and need insane amounts of RAM (if the 
NAS is hosting this, it may not have much RAM).


Both will work until you need to fsck (eg power outage or other instant/unclean 
shutdown). After that, you will wish you were using XFS.

If you have speed issues, one thing to keep in mind is that with the shell, 
fork/exec will often outweigh any compute cost in a regexp.


The core deal with interpreted languages (shell, perl, python etc) is that you 
should try to minimise the cost of the interpretation. So the classic shell 
example looks like this:


 # expensive, fires off separate commands per file
 for f in *.txt
 do
 cat "$f" | awk | sed | ...
 done

vs:

 for f in *.txt
 do
 file-specific-awk ...
 done | generic-sed | ...

i.e. a theoretical example where you can run a whole bunch of things though a 
single sed or whataver outside the loop. Obvious very dependent on your exact 
problem, but I hope the approach is evident.


There are flipsides to this of course; if the code becomes unreadable or 
unmaintainable then the programmer cost can exceed the actual real world 
runtime benefit, particularly for once-off tasks.


Re the unreadable bit, that is one of my rules of thumb for switching 
languages: when the task is no longer clearly and succinctly expressed.

While we're at it, I might suggest that "${f%.mp4}.mp3" isn't as clear 
as "${f/.mp4/.mp3}" for this particular for loop.


I think that's a little subjective; I personally prefer the former.

The pattern substitution method ${parameter/pattern/string} will also 
look more familiar to anyone who has used s/pattern/subst/ in vim, 
perl, etc, which is a small bonus.


for f in *.mp4; do
ffmpeg -i "$f" -c:a libmp3lame "${f/.mp4/.mp3}";

Yeah, until you try to make it robust. Eg against a filename like 
"temp4-take9.mp4", which your example will transmute into "temp3-take9.mp4", 
not quite the plan. Whereas the "f%.mp4" thing will behave correctly because of 
the greedy match.


(And yeah, if we were playing shell golf, it could be shortened to 
"${f/%4/3}" -- but that's certainly not as legible.


Agreed there.

Saving those few characters is likely not worth having to remember that /% 
means "match at the end of the parameter."  Although, using the % to anchor 
the substitution would be the most prudent thing even when using the full 
extension, in case you had a file with .mp4 elsewhere in the name. ;)


Ah, you've thought about this. 

I tend to feel that glob-based things are better than regexp based things for 
filename work, most of the time. Globs are simpler (albeit less powerful) 
patterns and shorter and more readable and often more intuitive. (When they're 
enough.)

The difference is not caused by ls but rather by the way the shell does

In case it isn't clear, only directories will have stuff inside them (/a/b...) 
so /*/ will only match directries.



BTW: If you're using bash, it will by default show you the expanded list

And in any shell you can investigate this kind of thing like this:

 echo /*

Using a subshell here purely so that the "set -x" applies only to the only

You need quotes around $PATTERN when you use it, thus:

 egrep "$PATTERN" file.of.links > links.in

using "*" instead of something more constrained can lead to exponential cost as 
the regexp engine tries many many more combinations as it attempts to match.  
Always write these things as pickily/conservatively as possible.


The other nit is that you should use $lowercase variable names in the shell

.ssh/authorized_keys file for whatever user you come in as.


If you have ssh-agent forwarding on, your ssh-agent service will be propagated 
through every ssh connection. Do this by putting:


 Host *
   ForwardAgent yes

in the "*" Host clause at the _bottom_ of your .ssh/config file. Assuming you 
want this on by default, which is a common choice for interactive users. It is 
off by default, and you can imagine why you might not want to on _by default_ 
in many circumstances. So that is a security policy decision for you. You might 
make this decision per host, and only forward the agent to hosts you decide to 
trust with it.


Note also that you need to enable ssh-agent forwarding in the .ssh/config on 
every host which will expect to forward the agent to the next box. It is 
consulted by the _local_ "ssh" command to decide these things.

If the OP uses ssh to go from system1:user1 to system2:user2, and then

that only system1:user requires a public key, and that system2:user2 can
ssh out without having *any* public key?




No, I said "private key".

If you are user1@system1 and you use ssh to log in to user2@system2, and
if you also have an ssh agent on system1 and instruct ssh to forward a
connection to the user2@system2 session, then you don't need a private
key in the user2@system2 home directory to connect to user3@system3.  You
only need to have the public key which corresponds to the private key
available to user1@system1 installed for user3@system3.  system3 will
request ssh authentication from user2@system2, and that request will be
forwarded back to the agent at user1@system1, which will answer it.

Using agent forwarding, you only need private keys on your workstation,
which you presumably have encrypted and otherwise made very secure against
an attacker obtaining your key files (which should, themselves, be
encrypted key files within the encrypted filesystem).

Had you thought about sed? Untested:

 sed -n

(One line, in case your mail read folds it.)

I've simplified the regexps, but I'm sure you get the idea.

Well done Cameron.  Thank you.
Moving the files did help. I don't know why I didn't try that before.  With 
everything else going on today, it must of slipped my mind.  I started going 
in circles.  I know I tried to move the files late last night but not with the 
paste like you suggested.


The advantage of the paste is that par2 has recited the filenames for you to 
your terminal, so cut/paste gets to pick them up again verbatim in whatever 
encoding is in play.


BTW, with the locale the utf-8 bit is what matters for this: it dictates how 
character codepoints are encoded when written to your terminal and, for locale 
aware apps, how they are encoded when filename bytes are generated. It also 
ditates how things like "ls" decode those bytes and decide what is printable or 
otherwise.


The .en-ca stuff is for higher level conventions like language, regional 
dictionaries, currency symbols, number separators and so forth.



This will go in my notes for future reference if it happens again.

It is funny that the par2 program had no problem seeing the repair 
volume files with the glyph but couldn't see the rar files with the 
glyph.


Is it possible you handed par2 the names of the repair files on the command 
line, but that par2 was getting the rar filenames from the metadata?

Is there any reason you can't just rename the file by hand, with "mv"? Or is 
this to fix some automation?



File name should be
Joe’s file.part01.rar

If I do ls I get
Joe?s file.part01.rar

ls -b I get
Joe\302\222s\ file.part01.rar


What are your locale settings? What does the output of "locale" say?

The locale settings affect several things; in particular it affects:

 - what ls will show you, because it affects what "ls" considers a printable 
   character


 - what your terminal displays for various byte sequences (this is driven by 
   the terminal emulator's idea of your local, not your shell, but they should 
   match)


 - what your keystrokes mean

Running par2 *.par2 runs par2 cmdline but all the files are missing 
and par2 says all the files are missing.


Target: "Joe’s file.part01.rar" - missing.
Target: "Joe’s file.part02.rar" - missing.
Target: "Joe’s file.part03.rar" - missing.
Target: "Joe’s file.part04.rar" - missing.


That is very weird. Normally, saying "*.rar" should be a totally robust thing 
to say. On the other hand, it is possible that those strings above are from 
inside the archive specification, and that is why they are not found: your 
files need renaming as you anticipate.


No matter...


Doesn't see the repair files either.
How can I escape these characters or run the program?  I have searched for a 
day to see how to run this program.  I have seen others ask the same question 
as well.

Is there a way to use 'exec' or another option?

I have tried to change the terminal character set with no luck or just 
haven't found the correct character set yet.


I cannot rename the files as the par2 and repair files look for the 
original file names.


I don't even know how to enter the characters in the terminal.

I notice if I look at the file name in a graphics file manager 
(dolphin), I just get a square with some unreadable code in it.


That means it is not decoding the filename into characters for which is has a 
glyph. That just means that Windows was using some other codeset whn it was 
saving the filenames into the archive. Windows is a bit of a nightmare in this 
regard.


Same if I try to look at it in a directory listing from a program.  Am I 
missing a font set for this and would that make it work better.


No. You've got a character encoding issue.

However, there is a way out. Get your error message above into your terminal, 
specificly by running your command again to ensure it is exact. Then use 
cut/paste in your terminal to effect 4 mv commands. So, like this:

This avoids figuring out how to type a weird filename.

There are other ways to approach this, but if this work it is probably the 
easiest.


As I cannot confirm the language the file was created in, I may be missing the 
correct font on my system to work with it as well.


This is not a font issue.

Try the above and report.

If you can determine which USB ports are on different controllers, you could

Or you could put a USB 2.0 card in the computer.


If he's going to do this, put in USB 3.0. It is impressively faster, and if

Smells fishy. I can't see an Internet website having any legitimate
need to open a raw IP socket and I really don't see Firefox needing to
do such a thing for normal operations. A web interface to an internal

BTW, the digits given, if used as a hex representation of a string,
equate to "Web content". Hm. I sure as heck wouldn't
enable the boolean or add a policy.

I think any MCE event shoudn't be ignored. There's just no way to know
if it's bogus or not. I get these on my machine periodically to no ill
effect and there's an upstream kernel bug with no response for years.
I thought it should be true that the hardware itself won't allow an
overheat, either GPU or CPU, and yet these messages suggest otherwise.

What I've been doing is using thermald which you can get from copr.
https://copr.fedorainfracloud.org/coprs/hadrons123/thermald/

However, what I just realized is that it says that 1.5.3 version build
has failed, and yet rpm -q shows 1.5.3 is on my system. And 'thermald
--version' also shows it's 1.5.3 and it's running. But it doesn't seem
to be working or producing the same messages it used to, where it'd
throttle the CPU automatically. Hmmm any wonder why it's seems hotter
than usual. Crap!


Well it appears to be doing something still, if I relaunch it in debug
mode. I guess maybe the new build is just not as verbose as the
previous build, by default. What I still don't get is how the copr
build state is failed, and yet I have that same build installed.





Thanks for the feedback, I've installed thermald, added it to 
/etc/rc.d/rc.local and so far have not seen a single cpu temp alert.

Can't get amarok to play mp3's via GStreamer backend

[CS DBA]

I've installed a number of the gstreamer rpm's (running Fedora 23) as

backend to vlc.  Anyone know how to get it to work with the GStreamer

Have a look at the output of dmesg. It may be apparent there what the
issue is. Most likely it's some bad memory or possibly some errant
firmware--either in the BIOS or a device (e.g. a wifi card or
something).

If it's not that, it could be your power supply starting to have issues.
Wonky power supplies do lots of odd things.

No second monitor - Fedora23 KDE spin

[CS DBA]

All;

I'm running Fedora 23, KDE spin. I've fully updated my system. several 
updated back I could plug in a second monitor, go to system settings --> 
display and click on the second monitor to 'enable' it


However a few updates back this functionality stopped working. Now I 
plug in the HDMI cable, go to system settings --> Display and it only 
show the laptop screen.


I've installed the Cinnamon desktop and it seems to work flawlessly per 
auto-adding the second monitor as soon as I plug the HDMI cable in.  I 
suspect this confirms that it's a KDE issue and not a Kernel issue, but 
I'm not 100% sure.



Any thoughts on debugging this?

rpmfusion updates-testing repos enabled in Fedora23

[CS DBA]

Hi All

I recently did a fresh install on Fedora 23 on a laptop (Lenovo Thinkpad 
X1 Carbon 3rd edition)


I followed up the install by installing the rpmfusion repos.
I simply ran the command from the rpmfusion site to enable 
rpmfusion-free-updates and rpmfusion-nonfree-updates


However today I noticed that the rpmfusion-free-updates-testing and 
rpmfusion-nonfree-updates-testing repos are also enabled.  I thought the 
testing repos were for packages still in testing mode, thus if I want a 
more stable system they should be disabled.


Should I leave the testing repos enabled? Has the rpmfusion repos 
changed such that I should  want this?


Thanks in advance

Wild guess:  Rather than give a list of compatible resolutions, try just
listing a low resolution one that gives you a big chunky display.

That, or look into if you can specify the font (a big one).


Tried multiple resolutions, as well as a bigger font via these steps:

|1)  grub2-mkfont -s 32 -o /boot/grub2/DejaVuSansMono.pf2 
/usr/share/fonts/dejavu/DejaVuSansMono.ttf|


2)  Edit the //etc/default/grub/ file adding a line:

Still no luck...

All;

I managed to get the grub boot screen to scale like this:


1) made a new font:
# grub2-mkfont --output=/boot/grub2/LiberationSerif-Regular.pf2 -s 36 -v 
/usr/share/fonts/liberation/LiberationSerif-Regular.ttf



2) made my /boot/default/grub file look like this:

GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rd.lvm.lv=fedora_f23host/root 
rd.lvm.lv=fedora_f23host/swap rhgb quiet"

GRUB_DISABLE_RECOVERY="true"
# GRUB_GFXMODE="1440x900x32;1440x900x24;1024x768x32;1024x768x24;auto"
GRUB_GFXMODE=auto
GRUB_GFXPAYLOAD=keep
GRUB_GFXPAYLOAD_LINUX=keep
GRUB_FONT=/boot/grub2/LiberationSerif-Regular.pf2
GRUB_GFXPAYLOAD_LINUX=keep
GRUB_TERMINAL=gfxterm


3) Deployed the change to my EFI grub config:
# grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

So now I have a readable font when the laptop boots, per the boot menu.  
Now I would like to figure out how to force the subsequent boot 
information to be a readable font.


Anyone have any ideas?


Thanks in advance

Ran this after the above:

grub2-mkconfig -o /boot/grub2/grub.cfg


still  no luck,


found a post about efi systems, so I ended up doing this:

1)  grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

2) ln -sf /boot/efi/EFI/fedora/grub.cfg /etc/grub2-efi.cfg

still no change in my boot menu resolution...

Network Manager oddities

[CS DBA]

All;

I'm running Fedora 22 (KDE Spin) on a Lenovo Thinkpad X1 Carbon.

Fedora 22 is great, most everything just works out of the box!  I owe 
much gratitude to the Fedora community!



There is one issue I have not been able to fix, it's more of an 
annoyance than a problem.
The network manager takes a long time to connect (about 60seconds) and 
sometimes it just stops
stops trying to connect to a wireless network after a minute or so and 
when I tell it to connect again it connects right away


Below is some /var/log/message output that I see when the wireless spins 
, stops connecting and then connects after I click on the "connect" 
button again



I'm using this wireless card:

Network controller: Intel Corporation Wireless 7265 (rev 59)


Thanks in advance

how do I get this to boot into this mode everytime??



My previous laptop had a similar issue with Fedora 21, I solved it like 
this... I created a script named 99-xrandr.sh, placed it 
in/etc/X11/xinit/xinitrc.d and made it executable by all (owned by 
root), the script looked like this:


---
#!/bin/bash

/bin/xrandr --newmode "1600x900_60.00"  118.25  1600 1696 1856 2112 900 
903 908 934 -hsync +vsync

/bin/xrandr --addmode eDP1 1600x900_60.00
/bin/xrandr --output eDP1 --mode 1600x900_60.00

---


You would want to set it up to force VGA1 to be 1920x1080 like so:

-- run cvt to get the needed string
# cvt 1920 1080
Modeline "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 
1120 -hsync +vsync


Then create your script:

#!/bin/bash

/bin/xrandr --newmode  "1920x1080_60.00"  173.00  1920 2048 2248 2576  
1080 1083 1088 1120 -hsync +vsync

/bin/xrandr --addmode VGA1 1920x1080_60.00
/bin/xrandr --output VGA1 --mode 1600x900_60.00



Not sure if this will work since your external monitor may not be 
connected at boot time, but worth a shot

Fedora 22 - Change login screen resolution?

[CS DBA]

Hi All;

I'm playing around with Fedora 22 (KDE spin) on a macbook pro retina. I 
can login and change the screen resolution and it stays permanent. 
However the login screen is still tiny, anyone know how to change / 
scale the resolution of the login screen?



Thanks in advance

Laptop screen recommendations - Fedora 22 & KDE

[CS DBA]

Hi all;

I'm currently running Fedora 22 on a Lenovo Thinkpad X1 Carbon (3rd 
gen).  Fedora works well on it, my only complaint is that the screen has 
a built in anti glare filter and seems washed out, I'm not sure if this 
is the anti glare filter or if it's that Linux support for the Video 
card (Intel HD Graphics 5500) is not quite there yet.


I'm planning to upgrade to a new X1 Carbon with more RAM and a faster 
CPU, I run the KDE spin. I wonder if anyone has any experience 'scaling' 
the KDE display with Fedora 22 (KDE 5 I believe) and what might be the 
best screen to run? Might the higher res screen fix my washed out screen 
issues? How well would it work with KDE 5? Other comments?


My screen options are as follows:

14.0" FHD (1920 x 1080) with WWAN

14.0" QHD (2560x1440) IPS with WWAN

14.0" QHD (2560x1440) IPS Multi-touch with WWAN



Thoughts?


Thanks in advance...

Linux on a Mac - restoring via rsync produces an unbootable laptop

[CS DBA]

Hi all;

Recently I installed Fedora 21 on a macbook pro, it worked pretty well.  
I take regular backups via an rsync of the entire system to an external 
drive.  After an update I had an issue I could not easily resolve so I 
restored the last rsync of the system. On other laptops this simply 
returns the system to what it was like at the time of the backup, 
however on the macbook it rendered it un-bootable, it simply booted to a 
mac error screen


Anyone know what I did wrong? Is there a different approach I need to 
take for backups?


Thanks in advance

What video card?

If nVidia, it is most likely and Optimus issue.






Intel HD Graphics 5500

Also, it turns out the HDMI port works even with the latest kernel.

Screen is still a bit washed out but not bad if I run "xgamma gamma .8" 
in /etc/X11/xinit/xinitrc.d/75-set-xgamma.sh

Fedora 22 - no external monitor after kernel update

[CS DBA]

Hi All;

I've just installed Fedora 22. The external monitor (Intel HD Graphics 
5500) worked fine initially. Then I ran an update of all packages except 
for the kernel, external monitor still worked.


Then I updated the kernel, going from 4.0.4 to 4.1.6 - now the external 
monitor does not work.


Thoughts?

Thanks in advance

Re: HD+ LED-backlit LCD screen washed out - found a temporary solution

[CS DBA]

All,

Just an FYI,

I created a file:
/etc/X11/xinit/xinitrc.d/99-xgamma.sh

made it executable, and added this content:

#!/bin/bash

xgamma -gamma .7


It seems that setting overall gamma to 0.7 does wonders for the display

I've tried all of the above with the updated kernel, no luck. The second
screen remains blank and I cannot move the mouse past the edge of the
laptop screen irrespective of if I boot / login with the monitor
attached or not

Kernel 4.1.4 breaks external display

[CS DBA]

Hi All;

I'm running Fedora 21 on a Dell M3800 laptop, been working great.
Updating to the latest kernel however breaks my external display
i.e. I plug the external monitor in and nothing happens, previous to the
update when I plug in the external monitor
the system would auto configure the second screen and I could use both
monitors.

I've googled the issue but not found anything.

Thoughts?

Thanks in advance

Asus UX303LA - fedora 21 - external monitor via mini display port not recognized

[CS DBA]

All;

I've installed Fedora 21 on an Asus UX303LA.

Most everything works great but I cannot get it to recognize an external
monitor
via the mini display port. I checked dmesg and saw no change when I plug
the monitor in.
I also booted with the monitor plugged in but still no luck.

Thoughts?

Re: installing Fedora 21 or 22 on a MacBook Air 7,1

[CS DBA]

I installed Fedora 20 on a macbook air like this:

1) burned the KDE live dvd,

2) plugged the dvd player into the mac usb port

3) held down the option button while I boot the macbook

4) when it comes up with the boot options choose the Fedora DVD (it
takes a few min before it shows up)

5) boot off the DVD, then do the install to disk as normal

Fedora 22 KDE spin, no wireless

[CS DBA]

All;

I did a new install of Fedora 22 - the KDE spin on a macbook pro, Fedora
21 worked well on this laptop but with Fedora 22 I cannot get the
wireless enabled, when I click the network icon in the system tray I
only see the wired connection and it does not show the check box to
enable/disable wireless...

I installed kmod-wl but when I do a 'modprobe wl' I get this:
FATAL: Module wl not found


Thoughts?

Fedora 21 on mackbook air - no tilde key

[CS DBA]

Hi All;

I've installed Fedora 21 KDE spin on a 2015 Macbook air.  I installed
the rpmfusion repos and enabled kmod-wl and kernel-devel packages to
enable wireless support.  At this point most everything works, the
screen brightness keys, keyboard backlight keys, keyboard volume keys,
etc all work.

However if I press the tilde/back tick key I get a les than sign (<)
and if I press shift-tilde I get a greater than sign (>)

Anyone know how to enable the proper behavior for these keys?

Thanks in advance

Update:  If I set the IPV4 section to manual and add the appropriate ip,

less than ideal


If I revert to Automatic again I still get the 192.168.0.100 ip address

Fedora 21 on a GIGABYTE P34Gv2-CF4 (NVIDIA GeForc GTX 860M)

[CS DBA]

All;

I'm thinking about getting a GIGABYTE P34Gv2-CF4 with these specs:


- 14.0” FHD 16:9 LED IPS Backlit Wide screen (1920x1080) Anti-Glare 
Matte Type Screen
- 4th Generation Intel® Haswell Core™ i7-4710HQ (2.5GHz - 3.5GHz, 6MB 
Intel® Smart Cache)
- NVIDIA® GeForce™ GTX 860M (4.0GB) GDDR5 PCI-Express DX11 w/ Optimus™ 
Technology
- 16GB DDR3 1866MHz [SKU-444BX] (Crucial Ballistix Sport Dual Channel 
Memory (2x8GB SODIMMS))

-512GB Crucial M550 Solid State mSATA III (Read 550MB/s - Write 500MB/s)
- 1TB Crucial M550 SSD (Read 550MB/s - Write 500MB/s (SATA III))
- Smart Li-ion Battery (4-Cell)

Most of the hardware seems compatible enough, I only have 2 concerns:

1) the 512GB Crucial M550 Solid State mSATA III, can I install the OS & 
boot off this drive?


2) the NVIDIA® GeForce™ GTX 860M (4.0GB) GDDR5, I've seen some posts of 
folks having issues with this card,
 will it work with the open source nouveau drivers (even if I get 
less functionality)? Or with the kmod-nvidia packages?


Thoughts?


Thanks in advance...

Help debugging / correcting wireless speed issue

[CS DBA]

Hi All;

I'm switching from Mac back to Fedora, my new Fedora laptop is a Lenovo 
W540 with this card:


Intel Dual Band Wireless 7260AC


I posted about issues earlier, which I've been able to resolve via a 
clean install. The wireless and wired connections connect immediately 
and behave as they should.


However, the Fedora laptop connected to my local access point shows a 
download speed of 1.63Mbps, while the mac, running the same test from 
the same site (http://speedtest.comcast.net) shows a download speed of 
26.89Mbps


Both laptops are sitting on the same desk, same distance from the access 
point


I don't expect exact matching speeds but this is a dramatic 
difference... can anyone help me debug / correct this?


Thanks in advance

It might not _hurt_ to back up /proc, /sys, and the like, but it's a waste
of time and effort since these are all entirely dynamically generated and
you can't possibly restore them.

You can use rsync -x to keep rsync from crossing filesystems, and then just
do it separately for each real filesystem you want.

Alternately, you might want to try the new "Fedora Atomic" --
http://rpm-ostree.cloud.fedoraproject.org/. As the name implies, this lets
you do atomic updates and switch back if thereis aproblem.


Thanks,

where would I find a complete list of the completely dynamic top level 
directories?

Backup question

[CS DBA]

Hi All;

I have an rsync script to backup my entire system each time before I run 
updates, as versions come & go I try and keep up with which top level 
directories to backup knowing that some like /proc are virtual...


Here's my question:  If I simply backup all directories (including ones 
like /proc & /media, etc) will the following work, or do I need to care 
about specifically excluding the virtual directories?



1) run the rsync backup of ALL directories in /

2) boot to a problem (say a boot to a blank screen)

3) boot into single user mode

4) run the rsync based restore (restoring everything from step 1)

5) reboot into the previous system state


Thanks in advance

I hope you are aware that there is a BIOS bug that can cause Linux to
brick the machine.  As in: once it happens, the motherboard needs to
be replaced.

See this, for example:

Nvidia Support

Hi All;

My shiny new Thinkpad W540 is due to arrive tomorrow. I'm preparing what 
I think I might need for the Fedora 20 install.


Nvidia support question, the W540 is equipped with this card:
NVIDIA Quadro K1100M 2GB

Anyone have any thoughts on the best video packages that would support 
this card?
Is the nouveau driver sufficient, or would the kmod-nvidia driver be 
better?

Do I need to download and install the Nvidia binaries?

The screen on the laptop is a 1920x1080

We'll be setting up some infrastructure around community involvement

I'm thinking that the OS would remain fully open source (GPL) and

I suspect that instead of waiting for the current HW vendors to

with it we can put effort into polish and functionality and quickly 
become the trend setters for MS and Apple to follow.


Thoughts?

Thanks in advance
Sounds good, but bucking the likes of MS and Apple? And I think it 
would be difficult to compete hardware-wise, since you wouldn't have the
huge base to get the advantage of large quantity hardware buys. Of 
course, Apple has that, but still charges an arm and a leg for their 
hardware. . . .
If you do pursue this, I hope you don't commit to something like 
Ubuntu, with its hated interface. Your system should offer some choices.


we will be all about choices, thanks for the feedback





Good luck!

It's a bit more the other way around. The hardware is designed first,
then they share the specs with the software vendors. It's logical in
the sense that they'd have a better shot at getting some money out of
M$ or Apple than the open-source community.

One example of this was with the old TI wireless chips...you _could_
poke a register in the hardware that could cause the chip to transmit
at a higher level than the FCC would allow. Obviously, that's sort of
illegal so they kept the interface of that chip under tight lock and
key and only told Microsoft about it. For several years the only driver
that would work was Microsoft's. The chip was discontinued after a
couple of years.

This continues with the firmware required for certain wireless chips
and such...it's only available from M$ or Apple and we've had to
create a program that rips the code out of the M$/Apple files and puts
it in a format our OS can use.


I wonder, what could be accomplished if a Linux based distro had the

It's been tried before and didn't work (Linuxware, Linux Hardware, Inc.
to name two). The economics of the OSS way of thinking and commercial
endeavors don't necessarily mesh well.

setters for MS and Apple to follow.


In many cases, if the HW vendors would just release the damned specs to
the OSS community, we wouldn't have to reverse-engineer so much stuff.
As it stands now, we have to get some other OS that does talk to it,
then instrument that and plow through the findings to figure out how to
talk to the hardware. Open specs would allow the OSS groups to get
started right away without all that rigmarole.

There are some vendors (such as nVidia and Intel) that do pretty
actively support OSS. I wish the others would.  Most peripheral HW
vendors (but by no means all) hamstring OSS by only sharing their docs
with the "big boys". Part of that is that they aren't likely to realize
an immediate return on their investment, but a large part of it is they
don't want to have to support fourteen-gazillion derivative operating
systems. I've been there and logistically it's a bloody nightmare.

I applaud your efforts and hope you'll have better luck than we've seen
in the past in such endeavors.


Thanks, I think part of the issue is timing. I hope the timing is right, 
we're seeing a LOT of HW that caters to what the vendors want at the 
expense of what the end users are asking for That's my theory.


I'll keep you posted

Unfortunately it's web order only... I can send it back if needed but 
some level of confidence before I pull the trigger would be nice...


Thanks for the feedback

Fedora on a Thinkpad W540

[CS DBA]

Hi All;

I'm thinking about buying this beast:
http://shop.lenovo.com/us/en/laptops/thinkpad/w-series/w540/#techspecs

With these specific options:

Video Card:
NVIDIA Quadro K1100M 2GB

Internal drive:
128 GB Solid State Drive, Serial ATA3

Secondary Drive:
2nd 500GB HDD, 7200rpm with Bay Adapter

Hi Res Screen help

[CS DBA]

Hi All;

I've installed Fedora 20 on a Dell XPS 15 with a 3200x1800 screen
It works well but I need a magnifying glass to see the text. I tried 
going into
system settings for KDE and setting the default dpi which sort of works 
for appps

but I still have a teeny tiny start menu and taskbar (and login screen)

If I set the screen resolution to something less than the 3200x1800 I 
get black lines on the sides...



The laptop has an Nvidia graphics card,

any thoughts on how to fix this?


Thanks in advance

Possible OT question

[CS DBA]

Hi All;

Our company is hosting an upcoming  "Open Data Summit" conference 
(opendatasummit.com)


I've posted to a few relevant mailing lists, such as the PostgreSQL 
Announce list.


Before I post here and potentially step over a line that I shouldn't I 
wanted to pose the question,
would it be ok/appropriate for me to post a "call for speakers" 
announcement here?

or is this simply too far off topic?


Thanks in advance

/Kevin

Fedora 20 install - can I revert to the old installer?

[CS DBA]

Hi All;

Is there a way to install Fedora 20 and force it to use the old 
installer, which gave me more control per installing multiple GUI's, etc?


Thanks in advance
