This page should be merged with BinaryDriverHowto/Nvidia. If you having trouble with the nv driver on a 6800 card it might be because of this: https://bugzilla.novell.com/show_bug.cgi?id=113203

X does not start after using nvidia-glx-config enable

(This only seems to happen on Dapper). If you installed the nvidia-glx package and then ran the script that came with it you may find that your X server will not start. The easiest way to fix this is to replace the config file with the automatically made backup

sudo cp (wherever the backup is stored) /etc/X11/xorg.conf

Now do

sudo (your favourite editor here) /etc/X11/xorg.conf

And find the section relating to your graphics card. There it will say something similar to this:

Section "Device"
        Identifier      "NVIDIA Corporation NV43 [GeForce 6600?]"
        Driver          "nv"
        BusID           "PCI:1:0:0"
EndSection

Change the Driver to nvidia BUT DO NOT CHANGE ANYTHING ELSE. That is where the script goes wrong as it appears to change the BusID to PCI:0:5:0. Do NOT change it or put it in if it is not there. Finally reboot/startx. Note: If you find that when X crashes (especially on Kubuntu), usplash kicks in just press ctrl+alt+f1 into a terminal. Log in as a normal user.

Revert from driver from nvidia to the ubuntu provided

If you have installed the nvidia driver as a manual way and you want to revert to the ubuntu nvidia driver:

 1. Go to the directory where is NVIDIA*.run, and run sudo NVIDIA*.run --uninstall.
 2. You have to reinstall all the packages that refers to nvidia via synaptic.
 3. Execute restricted-manager and enable the nvidia-glx*.

Next time you reboot you will get a nvidia driver working on all kernels, no API mismatch, No could not load nvidia driver...

OpenGL Problems

If you get such an error message:

...loading libGL.so: SDL: SDL_GL_LoadLibrary() failed! rc == (-1).
SDL_GetError() reports "Could not load OpenGL library".
failed
...loading libMesaVoodooGL.so.3.1: SDL: SDL_GL_LoadLibrary() failed! rc == (-1).
SDL_GetError() reports "Could not load OpenGL library".
failed
ASSERT: [qcommon/common.c:406] GLimp_Init() - could not load OpenGL subsystem
 (fyi)
----- CL_Shutdown -----
-----------------------
Error: GLimp_Init() - could not load OpenGL subsystem

Solution

Start the game with the following parameter: +set r_gldriver libGL.so.1 In my case Enemy Territory worked fine without it, but MOHAA not!

mohaa +set r_gldriver libGL.so.1
