If running 'xset dpms force off' puts your monitor into powersave mode
immediately, and if you boot with 'nomodeset', and that makes powersave
work for you again automatically, then you have the same bug.
After pondering this, since 'xset dpms force off' works to put the
monitor into powersave mode, then this has to be a bug. I just need to
figure out what to file a bug against: gnome-power-manager, x.org, or
kernel.
Yes when I do "xset dpms force off" The screen goes black which is
what it should do if the screen saver worked..
To do "nomodeset" I will have to reboot is suppose but not sure how
to apply that, "startx --nomodeset" perhaps or do I have to do it in
grub? Yes, you say boot with it. Not sure where to put it in grub.
It's a kernel boot parameter, append it at the end of the "kernel" line in
grub.conf
Another thing that I've noticed -- if you have a leftover /etc/X11/xorg.conf
from the previous Fedora release, rename xorg.conf and restart, letting X
start with a default configuration.
I haven't yet fully verified it, but even if I boot with the unmodified
kernel boot line, after removing xorg.conf, it looks like power management
also starts working.
