I had this same problem
way back when - brings back memories.
Anyhoo, back then there were a couple of things I had to do. In xorg.cong, I had to add:
Code: Select all
Section "Module"
load "glx"
EndSection
And I also
I've emerged nvidia-glx, ran nvidia-update xorg-x11
But the final fix was to make sure of the following
In xorg.conf Section "Module": make sure you've commented out 'dri' and 'GLCore', and in Section "Screen" make sure you've set "DefaultDepth" to 24 (or 16).
And obviously in Section "Device" the driver should be "nvidia".
The major problem was that I had the open source driver, which just wasn't cutting it. (nv=open source, nvidia=proprietary)
Most all of this is actually covered
here, and is a lot more up-to-date than any advice I can give you.
Go forth.
