[KDE4] OpenGL desktop compositing won't work

Hi,

I just installed KDE 4.1 on my desktop -- so far it's been working fine, except I can't get OpenGL desktop effects to work.

When I try to enable OpenGL compositing, I get no effects -- as in, the screen looks exactly as with effects disabled. On the tty from which I started X I can see:

Source code

kwin(3108): Couldn't find framebuffer configuration for depth 32 (no ARGB GLX visual)!
kwin(3108): Failed to initialize compositing, compositing disabled
kwin(3108): Consult http://techbase.kde.org/Projects/KWin/4.0-release-notes#Setting_up


Googling for this output didn't help me any -- I only found a page or two listing the KWin source file that produces this output. Following the link from the output, it seems that I have my driver set-up properly.

I've tried playing with the options in the Screen section of my xorg.conf, but with no
success. Other OpenGL apps work fine as well as other compositors,
including the KDE 3.5's one. XRender compositing works too, and I'm
using that right now -- but I'd love to get OpenGL working. :)

I'm using NVidia GeForce 7300 GT with NVidia driver version 173.14.09 on an x86_64 ArchLinux box. My xorg.conf contains this (removed things like font paths and input devices):

According to your output of kwin, that seem's to want to load a configuration for 32 bit depth. And that doesn't work. Could you maybe post the output of ~/kde4/share/config/kwinrc ?
To make composite work it needs a depth of 24.

no, pretty useless, sry. Hmm. I hear much people complaining about Nvidia and Compositing, but since i don't use Nvidia nor Compositing, i can't say more.
Maybe someone else here can step up?

Yeah, I've heard people complaining about NVidia and compositing as well, but from what I gathered, the complains are about crappy drivers giving them unusable performance while compositing, which isn't my case. Well, thanks for your effort anyway. x)

Okay, I fixed it. The problem was that I had XLIB_SKIP_ARGB_VISUALS environment variable set to "1". Unsetting it fixed the problem and now I get working OpenGL compositing with KDE 4.1.

Upgraded Xorg with portupgrade and then i got problems with nvidia-legacy driver (173), Fetched update from nvidia´s site as there was no upgrade in ports tree. now everything works again.
