Description of problem: If the screen saver is on, and the power save is on and later than the screen save, and the power down computer is not set to never. If the monitor goes into screen saver mode, but is reactivated before the power save mode activates, then the power save mode still activates at its scheduled time, even with activity in the screen. Waving the mouse or keystrokes will reactivate the monitor.

4. Wait until monitor goes into saver mode, 1 minute.
5. Wave the mouse around.
6. Wait another two minutes. Screen will go into power save mode.

See bugzilla 501601 for some tests I did.
Nouveau driver, crt monitor, old video card, not eligible for modeset according to nouveau.
Actually, the reporter initially commented on the bug for that issue - 501601 - but I commented that I don't believe it is the same issue, and asked him to open a separate report.
If you read the symptoms and the tests on 501601 carefully, the reporter is able to entirely mitigate this problem by changing the timeouts, which is not the case with 501601. This appears, to me, to be a different bug.
