It would appear this bug is probably related to Compiz/opengl and the video driver/chipset.
I had the exact behavior occur after having turned off the power management and screensaver. I had several programs open and I was switching back and forth several times. When I hit the Display desktop button the open windows all shifted and an error box popped up with this statement, "Your window manager does not support the show desktop button or you are not running a window manager." I have now turned off all special effects managed by Compiz, the screen saver and the power manager. I'll update if the problem shows up again. -- Windows shifted and non functional after monitor goes in standby https://bugs.launchpad.net/bugs/657859 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
