I cannot use ACPI on my desktop pc and I have a nVidia card using the XFree module provided by nVidia. APM gets disabled by this module: kernel: apm: set display: Power management disabled Nevertheless, "xset dpms force standby" is working properly without any Problems. Perhaps DPMS is supported by APM, ACPI and/or the XFree modules... Jochen Am Samstag, 7.
