I see this phenomenon too, just as described (sometimes within an hour). The
screen locks and goes black, but the saver itself doesn't kick in. The screen
doesn't switch off either. Restarting killall gnome-screensaver &&
gnome-screensaver restores the correct behaviour for a while.

i have found this error today:

libGL warning: 3D driver claims to not support visual 0x4b

Comment 4 Vladimir Florinski 2006-11-26 18:57:32 EST
Confirm bug as well. Occurs regardless of hardware (Nvidia and Intel tested) and
regardless of the screensaver used (non OpenGL ones have this too).

Comment 7 Vladimir Florinski 2006-11-27 12:57:10 EST
I investigated this some more and found that the reason a screensaver theme does
not start is because the "throttled" flag is set in gs_manager.c. This is
evident from comparing the two logs that I attached. Whereas the successful
activation log shows that "job" (i.e., the actual process of the screensaver
animation) is started, the second log shows that the screensaver is "throttled"
and the job does not start. Now, it appears that the "throttled" flag is set by
gnome-power-manager after the sleep timeout has elapsed (this is set in the
Power Managment menu). After a computer was left idle for that period of time,
gnome-power-manager sends gnome-screensaver a D-BUS message telling it to stop
the animation (since the display is going to be put to sleep, so why waste CPU
cycles). But it seems that the power manager does not inform gnome-screensaver
when the display become active again (or perhaps, gnome-screensaver is not

I hope the above info will be useful for developers. A similar bug was reported

Ah this is a known gnome-power-manager bug, let me look for the upstream report...

Hi guys,

Would you mind testing gnome-power-manager-2.16.0-4.fc6 which should appear in
updates-testing today or tommorow, or gnome-power-manager- which
should be in tomorrow's rawhide compose?

Tested with gnome-power-manager-2.16.0-4.fc6 and the problem is no longer there.
