No GLXFBConfig for Depth 32

Sat, 06/02/2007 - 01:00 — Sean

I love Beryl/Compiz, b0ut I have found them to be a bit finicky (understandably). Under Kubuntu Feisty with an Nvidia 7300 Go video card, I ran into a tremendously annoying problem where the title bars for windows were not visible. Looking at the output for beryl-manager, I saw the following:

No GLXFBConfig for Depth 32

I found this puzzling because I’m not running at a 32 bit depth - I’m running at 24. Again, the Ubuntu forums saved me:

That told me to add the following two options to the Screen section of my xorg.conf file:

Option "AddARGBGLXVisuals" "True" 
Option "DisableGLXRootClipping" "True"

The screen section of my xorg.conf now looks like the following:

        Identifier      "Default Screen"
        Device          "nVidia Graphics Controller"

        DefaultDepth    24
        Option          "AddARGBGLXVisuals" "True"
        Option          "DisableGLXRootClipping" "True"
