Ubuntu

X Server will not work after updates

Asked by DanielTC

General specs:
Intel Core 2 Duo E6600 (CPU)
GIgabyte GA-n680SLi-DQ6 (MB)
eVGA 8800GTX (GPU)

I installed Ubuntu 7.04 and had no problems at all until I restarted after installing various updates (at least 70); things went downhill after that.
Ubuntu seemed to be booting again, but after it seemed to have finished it displayed error, saying X Server will not work and might be modified incorrectly; apprently it has to do with my graphica driver:

nVidia: could not open the device file /dev/nvidia0 (Input/Output error).
(EE)NVidia(0) failed to initialize the nVidia graphics device PC11: 1:0:0

Can you check if you have this device file:

/dev/nvidia0

and what are its permissions?
It should be something like:

crw-rw---- root video

Worth also checking if you are in the video group:

id

Should say ...44(video)...

How do I check all that stuff in non-graphical interface? I am new to Ubuntu, so I really do not know.

Oh, forgot about it, but I updated my graphics driver, too, when I tried to activate Desktop Effects.

Give these two commands in the terminal:

ls -l /dev/nvidia0
id

and paste here the output.
Also, tell us how you updated the graphics driver: using the restricted driver manager or you downloaded and installed it from a non-ubuntu source (like using the envy scripts or from nvidia)?

I see you have the 8800 card too, which have had some issues.

Try running the following at the terminal to let the nvidia program recreate its settings in the xorg.conf file and recompile its librarys:

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
sudo nvidia-xconfig
