Indeed, I can confirm that with the recently released stable 295.20 driver version the problem went away and no more hangs are experienced after resume and the desktop is immediately responsive.
Switching to the console and back also works fine, although there seems to be one buglet left: Switching forth and back to the console and the X server requires the triggering of a full redraw (e.g. by switching to another virtual desktop) in order to restore the full desktop properly from an initially black image. Upon resume and after logging in, there are some graphics artifacts (graphics memory corruption?) at the area where the unhidden dock would reside. Once an action overdraws that screen area (the dock is unhidden or a full refresh is triggered) everything is back to normal. Not sure, if this is something that is supposed to be taken care of by the driver or by the compositing manager. Thx a lot for the fix of the modeswitch hang, though, which works beautifully again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/933212 Title: FBO-using applications unresponsive for a long time after modeswitch To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/933212/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
