Re: SMBus Quick command not supported
I have found a fix for this problem.
I was using debian, and the directory structure for the Xorg's distribution has been suffering many changes. Apparently, the nvidia installer can not correctly install the new modules for the X server, that tries to load its own glx module unsuccessfully.
Go to /usr/lib/xorg/modules/extensions
and there rename the file libglx.so.1.0.8276 to libglx.so
If you still have problems, remove the kernel module eeprom.
