I have beryl-core 0.2.1 installed with Xgl and driver ATI (fglrx), and when update my system using "emerge -DuN world", beryl start but does not open aplication, and does not answer. Look for help in the Gentoo forums and found the reason of the problem: randrproto 1.2 and libXrandr 1.2.0. They cause problems. The solution: emerge -av1 =randrproto-1.1.2 =libXrandr-1.1.1 and my Desktop return !! Reproducible: Always Steps to Reproduce: 1.update randrproto and libXrandr (emerge -DuN world) 2.startxgl (start kde + Xgl + Beryl) 3. Beryl slow and does not open aplication (Very unstable) See http://forums.gentoo.org/viewtopic-p-4019833.html#4019833. It is my first report, sorry if I have not done it well.
Remerge xorg-server after updating those libs, see http://bugs.gentoo.org/show_bug.cgi?id=175196 and http://bugs.gentoo.org/show_bug.cgi?id=174959#c7
okie, someone beat me to posting the solution...
Same problem here but the proposed solution doesn't work for me. I had to reemerge x11-base/xgl because it depends on randrproto and now everything works perfectly. I also reemerged beryl-core (depends on libXrandr) but now I think that this last action was useless :)
new release of upstream is coming..and beryl itself is now depreciated from upstream in favor of the joint effort.
