Note that you have to patch the output of iasl -d, *NOT* the .asl file that acpidump generates. There is a difference although they look alike.

According to Mark, this actually should work from within X -- something to do with DPMS. I haven't gotten around to testing it after my reinstall though (*cough*Zelda:WW*cough* :) > Can you suspend yours? Any more clever tricks?

The ACPI thing got more coverage on -current, but the suspend stuff is probably -mobile topic, yeah :) HTH, --Stijn --=20 "Diane, 2:15 in the afternoon, November 14. Entering town of Twin Peaks.
