The problem is that you don't have libglcore.so as part of proprietary drivers (nvidia, for e.g.). At this time libglcore is substituted with mesa-dri/glx (which is abs. soft-ware rasterizer, not using your video card 3D acceleration) and xserver-xorg-video-nouveau (queer soft-ware subst. for native video card drivers).
Try to run glxgears, glxinfo and you'll see error - glxinfo: error while loading shared libraries: libGLcore.so.1: cannot open shared object file: No such file or directory -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/932125 Title: compiz crashed with SIGSEGV in Glib::Source::prepare_vfunc() To manage notifications about this bug go to: https://bugs.launchpad.net/compiz-core/+bug/932125/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : [email protected] Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
