It happens to me very frequently. When I use 'ctl+alt+arrows' to switch between workspaces, it can happen. The probability of crash goes higher e.g. when I have a chrome page open and watching a youtub in fullscreen.
my details: Linux vostro 3.16.0-60-generic #80~14.04.1-Ubuntu unity 7.2.6 Compiz 0.9.11.3 I tried to downgrade and upgrade my nvidia driver, but it does not make any difference. These things helps: switching to tty1 and going back to graphical mode, but not always fixes the problem. #killall -9 compiz which works like logging out and logging in again...but results in lost of work and stuff.... please let me know how I can give you a better log/description -- 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/815996 Title: Desktop occasionally freezes/locks up when switching workspaces To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/815996/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : compiz@lists.launchpad.net Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
