List,
I've been bugged by the fact that the dpms function will not work on this 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 as to 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?
