Also notice this segfault in /var/log/messages when I toggled desktop effects: Dec 6 11:58:31 tlondon kernel: compiz[3153]: segfault at 3cc262ec10 ip 0000003cc262ec10 sp 00007fff3cac2508 error 14 in libstartup-notification-1.so.0.0.0[3cc5a00000+9000] Perhaps a duplicate of bug 474586 Yup. Reverting gnome-screensaver fixes the problem. Wouldn't have thought to look there.... Thanks. *** This bug has been marked as a duplicate of bug 474586 *** |
