I have a Toshiba M30-742 laptop ( with Phoenix BIOS
). Am running gentoo on it. All seems fine. However there is a problem with the monitor not turning off. ACPI has been turned on in the kernel and also toshiba_acpi is enabled.
When I close the lid the monitor switches off automatically. I am running acpid, however I haven't configured any scripts for the LID close event. I can see that the lid close and open states and events are recognised properly by the acpid. /proc/acpi/toshiba and /proc/acpi show correct events.
What I have already tried:
1. xset dpms force off (display blanks but backlight is still on)
2. toshiba-utils (they don't support phoenix bios)
3. xscreensaver power management ( same symptoms as 1 above)
4. Have googled a lot.
The laptop has an nVidia Go5200 card. I am running binary drivers from nvidia (actually "emerge nvidia-kernel" etc. in gentoo). The DPMS option has been set in my xorg.conf.
Please give me some pointers to solve this problem.
