The radeontool port will successfully turn the video signal on and off (with dac on/dac off), though it doesn't actually get the monitor to go into power-save mode. After coming out of suspend, radeontool does nothing, merely complaining that it is "Not memory mapped" (I can see the error message by ssh'ing in and running radeontool that way). > > > > I think one solution we should try is to do the > various BIOS video > > reset routines after powering up everything again > (D3->D0).

I tried it with hw.acpi.reset_video=1 and =0. radeontool still doesn't work w/ this patch either. Also I should note that the tty green saver puts my monitor in and out of power-save with no trouble (yes, i have also tried turning the green saver off, but it hasn't made a difference either). Before I ran any of these tests, I set my computer to not load X on boot and rebooted. Any more suggestions? /brian ____________________________________________________________________________________ Looking for a deal? Find great prices on flights and hotels with Yahoo!
