Bug Description
Binary package hint: gnome-screensaver
Surprised if no one else has reported this, but it is an intermittent thing. I've been using 11.04 throughout alpha and beta for a while now, and have even done a fresh install...
Now and then, after gnome-screensaver is enabled either by locking the screen or automatically after the inactivity time runs out, after unlocking the screen and coming out of gnome-screensaver, window focus will act like it is stolen by an invisible program. Clicking on windows will move them to the foreground, but not make them the active window via window title highlighting. If I continue to alt-tab and click around, especially after clicking on menus, the problem will get worse to the point that I can't click anywhere or do anything on the desktop at all, even with most keyboard shortcuts. Alt-tab no longer works. Menus aren't displayed. Windows aren't movable via alt-left-
While in gnome-terminal, I noticed that the cursor would only be selected for 5 seconds or so at a time before being inactive for 5 seconds, rinse, repeat, making it difficult to type things. Killing gnome-screensaver puts a stop to this, but does NOT fix any other problem with the desktop being unresponsive to most keyboard or mouse shortcuts. To me, that would seem to indicate a problem with gnome-screensaver, and perhaps why killing the process doesn't completely fix it is due to some lingering X issue that gnome-screensaver caused. Add to that the fact this only happens after a gnome-screensaver unlock, and it's pretty convincing that it is the problem, though perhaps Compiz or whatever compositing manager could be compounding the issue?
I find it hard that I'm the only one who has noticed this intermittent issue. It's almost like there is a stuck key suddenly, and my keyboard is going bad, but I doubt it because nothing I hit or do will fix this problem, yet after a restart everything is fine, while a stuck key would immediately make the problem occur again.
Anyone else find this bug?
I just had this happen again. The only similarity may be having Thunderbird open, not sure if I have had it open during each of these occurrences. Perhaps the new email notification window in Thunderbird messed up the window focus.
The only other commonality seems to be that you need to wait for a long while. It doesn't seem to happen after quick locks/unlocks. Perhaps that means the bug is in power saving mode if this is only happening after it puts the monitor to sleep.
