I am seeing this about once a day. It happens after a compiz crash - when it happens, unity tries to restart but the launcher and panel don't appear.
Just now I tried the suggestion in comment #21 (ie from a root tty, kill the X session and do "killall -SIGABRT lightdm; start lightdm"), but it didn't work - after restarting the X session the problem persisted. I had to completely reboot the machine to fix it. Since this bug is marked fixed, should we open another one? -- 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/851345 Title: compiz crashes on i915 graphic module with GLX_EXT_texture_from_pixmap is missing To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/851345/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : [email protected] Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
