Ahem. I've traced this locally and it doesn't *seem* to be a compiz problem. Compiz is waiting for the next frame, and X is waiting for the kernel to tell it the next frame has happened.

Ok. So, for a work around I think we can start compiz with the vblank_mode=0 environment set and vsync disabled; this will stop compiz being blocked waiting on vsync, but in return allow some tearing to occur. With vblank_mode=0 I can toggle dpms on/off with a GL screensaver running - which seems to be a trigger for this - until my GPU locks up.

Not sure this is unity-related, I see this with the classic 3D desktop as well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/740126 Title: compiz hangs randomly several times per day -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I have a similar bug. In my case the screen stays black except for the mouse cursor. It is not frozen though, I can move the mouse cursor just fine and it changes shape when I get in the middle of the screen (over the invisible password prompt). When I blindly enter my password the screen gets unlocked, as I can see by moving the cursor around (it changes shape according to the applications on my invisible workspace). Only way to regain access so far was to kill the session. Can any of you still move your mouse when it happens? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/740126 Title: compiz hangs randomly several times per day -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
