[SOLVED] Trouble with Xorg on Thinkpad e520

Postby petter.s » 2012-01-17 14:19

Hi!
I have just installed the "standard" debian cd. After that I installed xorg and xmonad and created a .xinitrc file with contents: exec xmonad
running startx gets me into xmonad, but with resolution 1024*768 instead of 1336*768

After some googling I figured I should change some stuff in /etc/X11/xorg.conf. But this file doesn't seem to exist so after some more googling it seem as it should be created with Xorg -configure. But this command gives a long output (can't scroll in it or pipe to less :( from tty1) ending with:
Number of created screens does not match number of detected devices.
Configuration failed.


Do you have any tips of a next step to solve this?
I previously ran ubuntu and had full resolution so it isn't a hardware problem.

You can use xrandr or create xorg.conf file manually to specify desired resolution.
There are many tutorials on the net on how to do it.

I previously ran ubuntu and had full resolution so it isn't a hardware problem.

It's possible. Combination between kernel version, xorg version, more recent driver, etc.
You may want to add information about your current running kernel, your graphic card and module/driver is used ( lspci -knn )

Hi,
I have tried xrandr, this is it's output:
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 800 x 600, current 1024 x 768, maximum 1024 x 768
default connected 1024x768+0+0 0mm x 0mm
1024x768 61.0*
960x600 0.0
800x600 61.0


This is odd because my maximum resolution is 1366 x 768

uname -r gives:
2.6.32-5-amd64


lspci -knn gives:

Maybe you will get a better luck with kernel 2.6.39 from backports and backported X too.

Since you're familiar with Ubuntu the same solution may work with Debian. Read the last post in this thread :

xrandr --newmode "1336x768_60.00" 83.00 1336 1400 1536 1736 768 771 781 798 -hsync +vsync
Gave result
xrandr: Failed to get size of gamma for output default


So I tried backporting the kernel according to this guide:
https://ticketing.nforce.com/index.php?/Knowledgebase/Article/View/27/0/upgrading-the-kernel-to-2638-in-debian-6-squeeze
and after a restart I had the correct resolution!!!!

Thank you very much mslinux, you have really helped my a lot. It was stressful not having a working computer.

All graphics were a bit slow so I followed your advice and backported X too (I think, I ran apt-get install xorg) and after that everything was smooth!

Just to be able to solve these things myself in the future, how did you know I should backport the kernel? Did you find any bugreport? Intuition?

Thanks again,
Petter

Glad I could help. Anyway, you helped yourself by putting a clear and verbose information of the situation you were facing.
how did you know I should backport the kernel?

Your lspci output :
00:02.0 VGA compatible controller [0300]: Intel Corporation Sandy Bridge Integrated Graphics Controller [8086:0116] (rev 09)


Installing Debian in various hardwares will give us an experience on what to do when dealing with certain hardware confugurations.
