Using F9, with KDE 4.0.4 desktop, my LCD display never seems to enter
power-saving mode. I have a screensaver configured to kick in after 5
mins, and that works fine. The Xorg log file shows that DPMS is enabled,
as does 'xset -q'. Running 'xset dpms force off' (or standy/suspend) and
the screen turns off, so it can do it. I have left the system for nearly
an hour, but the monitor is still on. This occurred under the vesa
driver, but I have today installed the latest Nvidia drivers and the
problem still exists. F8, using the same hardware, had no such problem.
Upon further investigation, the problem *only* occurs if the "Start
automatically" option is set when configuring a screensaver. Disable the
option, and DPMS works as expected. Most odd. Bugzilla'd at
https://bugzilla.redhat.com/show_bug.cgi?id=449280
This is not a graphics card driver problem.
