I have some weird behaviour from nvidia drivers so far. My systemparts that are involved:
nvidia GTX 560 Two Screens Ubuntu 14.04, fresh update from 12.04,
When I execute
sudo nvidia-settings and click on apply none of the adjustments are taking place. On closing nvidia-settings I get an error in the terminal:
(nvidia-settings:24231): GLib-CRITICAL **: Source ID 5984 was not found when attempting to remove it The program 'nvidia-settings' received an X Window System error. This probably reflects a bug in the program. The error was 'BadValue (integer parameter out of range for operation)'. (Details: serial 1154 error_code 2 request_code 157 minor_code 25) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)
I am not getting any ideas from the logs either:
dmesg | grep nvidia [ 22.493961] nvidia: module license 'NVIDIA' taints kernel. [ 22.498143] nvidia: module verification failed: signature and/or required key missing - tainting kernel [ 664.524208] init: nvidia-persistenced main process (23947) terminated with status 1
Something reappears allways in xorg.log:
[ 33.178] (II) NVIDIA(GPU-0): Display (Samsung SyncMaster (DFP-0)) does not support NVIDIA [ 33.178] (II) NVIDIA(GPU-0): 3D Vision stereo.
Well... I hope anyone can help me! Thank you in advance!
Edit: What I tried so far:
- Purging nvidia-drivers and reinstalling them
- deleting xorg.conf
Edit 2: Just had an idea: Launching a game from my steam account. Doing that I get:
Could not find required OpenGL enty point 'glColorMaskIndexedEXT'! Either your video card is unsupported, or your OpenGL driver needs to be updated.
