Resolution messed up after upgrade (12.2)

English Hardware

**Setup:
**
OpenSUSE 12.2 (64 bit) KDE on a laptop (i7, GeForce GT, etc).

**Problem:
**
I used zypper to update the system and I also installed the alx network driver. After a reboot my screen resolution is stuck at 1024x768 (it was previously much higher, maybe 1900x1200 or so).

The output from xrandr:


xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1024 x 768, current 1024 x 768, maximum 1024 x 768
default connected 1024x768+0+0 0mm x 0mm
   1024x768       76.0*

Any suggestions? Thanks in advance.

I should add that when installing alx I had to install the kernel-devel package as well. Perhaps it’s a kernel issue?

So, if this Laptop uses nVIDIA graphics at all time (Not Optimus dual video) you might want to consider installing the nVIDIA proprietary video driver. I have some blogs on the subject:

Installing the nVIDIA Video Driver the Hard Way - Blogs - openSUSE Forums

AND

LNVHW - Load NVIDIA (driver the) Hard Way from runlevel 3 - Version 1.46 - Blogs - openSUSE Forums

AND for a faster system, look to a new kernel version 3.5.4 you can compile with this:

S.A.K.C. - SUSE Automated Kernel Compiler - Version 2.78 - Blogs - openSUSE Forums

Thank You,

Run the following command to get pertinent graphics info:

/sbin/lspci -nnk

Just post the output relating to your graphics hardware.

Alternatively, this can be useful too

/usr/sbin/hwinfo --gfxcard

You should start by checking /var/log/Xorg.0.log, as it will help with the diagnosis. Upload the contents to SUSE Paste, and paste the link to it here, so that we can help with a solution.
