Public bug reported:
I use xserver-xorg-video-radeon (on a Radeon HD 5770) , so far without
problems. After the upgrade to xserver-xorg 1.15 kwin wasn't able to switch to
it's OpenGL backend anymore and used XRender instead. kwin isn't very
informative why GL failed, however running glxinfo shows
Error: couldn't find RGB GLX visual or fbconfig
I don't know where the problem comes from, I don't get any other GLX-
related errors
