compiz not working in ubuntu 10.04

[Dejavou42]

I think I have this figured out. I'll mark it as solved as soon as I make sure... To fix the "Xlib: extension "GLX" missing on display ":0.0" error message, I ran sudo nvidia-xconfig, which generated a new xorg.conf file. That brought me back to the same problem I had to begin with: "compiz (core) - Warn: No GLXFBConfig for depth 32." To fix this problem, I found that I needed to add some lines to my xorg.conf file:

If there is a module section, add: " load "glx" " to that section. If there is not a module section, just copy and paste this to the bottom of your xorg.conf file.

ection "Module"
	Load "glx"
EndSection

Also, I found that I needed to add some lines to the screen section:

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

The previous two lines are actually what fixed the 32 bit depth error message.

At this point I was able to enable compiz, but all of the settings did not work, and they wouldn't save.

I found, from this thread, that I had a package missing that compiz needed. it was :

compiz-fusion-plugins-extra

I also found a helpful list of other packages that compiz needed. (I already had the rest of these installed)

compiz compiz-plugins compiz-gnome compiz-core compiz-fusion-plugins-main compiz-fusion-plugins-extra compizconfig-backend-gconf compizconfig-settings-manager

Last but not least, I found a nice tool here, that will check if compiz is able to run on your system.

I hope this info is helpful to someone else too!

You also get the error,
"compiz (core) - Warn: No GLXFBConfig for depth 32"

if you have this environment variable set.
export XLIB_SKIP_ARGB_VISUALS=1

I had set export XLIB_SKIP_ARGB_VISUALS=1 globally because I had a program that didn't play nice with compiz. Then the next day when I started my computer compiz would not work. After much searching I found out that setting export XLIB_SKIP_ARGB_VISUALS=1 caused the problem.

I removed export XLIB_SKIP_ARGB_VISUALS=1 from my .profile and added it to the script that starts the program that doesn't play nice with compiz. Problem solved!
