Public bug reported: Binary package hint: xserver-xorg-core
I have Ubuntu 10.04 LTS, 64bits an update of xserver-common and xserver-xorg-core arrived today that, once I had restarted my laptop, made compiz crash (and going into "fallback mode") and no other application using opengl was able to run (e.g. glxgears). compiz-check was failing too. After some googling, I found several threads related to the crash report from compiz, and tried some solution. the only one that worked was forcing xserver-xorg-core version to 2:1.7.6-2ubuntu7 (lucid) instead of the latest 2:1.7.6-2ubuntu7.8 (lucid-updates) After downgrading, everything works fine again (at least compiz, glxgears) The error message from compiz (and compiz --replace) is: compiz (core) - Fatal: Root visual is not a GL visual compiz (core) - Error: Failed to manage screen: 0 compiz (core) - Fatal: No manageable screens found on display :0.0 Launching fallback window manager compiz-check error message was : Gathering information about your system...
