Thanks for following up. I've since upgraded to 7.10. This specific problem hasn't recurred, but I have had intermittent stability problems similar to what was reported (though none as serious) - in the most recent problem, I booted the machine and logged in while the monitor was turned off. After turning on the monitor, I was unable to change the screen resolution. I logged out then logged back in, and my desktop was gone. The window manager froze and I had to do a hard shutdown. Things recovered well after reboot.
As a practical matter, given the frequency of occurrence and the unpredictable nature of similar behaviors (and the bug backlog), I'd suggest changing the bug status to 'non-reproducible' or a similar category for now, or leave it as incomplete, and close it. This doesn't sound easy to trace down... -- gnome stops managing windows/workspaces https://bugs.launchpad.net/bugs/107652 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
