I too exhibit this issue. I run an Nvidia card in a Dell Vostro 1400. A bit more info of my testing:
-I've tried to Restricted Nvidia drivers and the EnvyNG 173.14.12 drivers with no difference. -If I manually kill compiz prior to Suspend I have a higher probability (1/2) of getting a normal wake-up with password field. -If I leave compiz running prior to Suspend I have a lower probability (~1/20) of getting a normal wake-up. -There is no difference between closing the lid and manually selecting shutdown & suspend. Extraneous facts: -Compiz will randomly crash while rotating screens, a manual restart works properly. -Restarting X (gnome) with CTRL-ALT-Backspace increases the frequency of Compiz freezing. -Upon wake up from Suspend, the taskbar is always frozen. My work around is opening Tomboy (which loads a taskbar icon) and then close it, after that the taskbar returns to normal operation. Hopefully this helps someone, I am very willing to do testing if anyone would like to guide me. -- [nvidia] compiz displays white screen when locked https://bugs.launchpad.net/bugs/160264 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
