List,
Did not get any response from the first attempt, so thought I'd ask again.
I've been bugged by the fact that the dpms function will not work onthis machine, and perhaps now I have some clue as to why. Looking at the Xorg.0.log, I see where "Open APM failed (/dev/apm_bios) (No such file or directory)" which tells me perhaps this is the reason why it won't turn off the monitor. Also, this line prior to the other. `fonts.dir' not found (or not valid) in "/usr/X11R6/lib/X11/fonts/local/". That part I can maybe fix, but I have no clue what should be in the /dev/apm. The only thing that will happen is the monitor will go into screeensaver mode, or if no saver selected, it will do nothing, not even blank.
What should the /dev/apm contain? Where does it pick up the info asto what should be in there, from a probe of the hardware? That said, does the fact that I'm using a custom video driver from ATI make any difference?
Thanks for any help.....
Sam-
On my laptop, which is using ACPI (default with the newer distros/kernels), I see see the same message in my Xorg.0.log
(WW) Open APM failed (/dev/apm_bios) (No such file or directory)
However, I do see the following from DPMS
(II) Loading extension DPMS (**) Option "dpms" (**) RADEON(0): DPMS enabled
Do you have
Option "dpms"
in your monitor line of xorg.conf?
Alternatively, if your computer has apm bios, you can add
acpi=off
to the kernel entry in /etc/grub.conf and reboot. Some server class hardware (machines with ServerWorks chipsets) don't have an apm bios.
Also, Are you running the screensaver? If you are running Gnome, go to Preferences > Screensaver and in the Advanced tab, make sure that Power Management Enabled is selected.
Hope this helps.
