[Bug 1046996] [NEW] GL Screensavers Lock Out Keyboard Kubuntu

[Launchpad Bug Tracker]

There are times after my system goes to a GL screensaver and
PowerManager is set to turn the display off soon after lock the screen,
I cannot get any keyboard or mouse input to work to turn the screen back
on and ask me for a login password.

The Caps-Lock key no longer lights up on my laptop in this state.
Previously I thought the system was frozen.  However, after some
research from a different system over SSH, I found that the screensaver
was running at 100% CPU load on one of the cores.  I killed the PID of
the screensaver, and keyboard input returned which allowed me to wake
the screen and get a KDE unlock window to return to my Desktop.  The
Caps-Lock key lights up again if that matters to you on how the system
is responding to input.

Most users likely hard reset the system.  This is not necessary if you
can SSH back in.  This is also why I could not find a similar bug since
the rest of the bugs I saw were about the system itself freezing.

This will not reproduce the error, but the current xsreensaver I used was flocks, which you can see with:
'kxsrun flocks -- -window-id %w'
