I've been trying to put my nVidia GForce 2 card to sleep. Before booting Linux, my computer turns the display off after 1 minute (I can tell that turns of the graphic card because the power consumption - monitor excluded - drops by 25 watts)! I could not get the computer to turn the display off in linux, is there a way to enable that so Linux can listen to my ACPI BIOS?
I have kernel 2.6.6 with ACPI support (it does work) and I am using the latest nvidia driver that has ACPI support (I also tried switching from agpgart to nvagp but it didn't help).

ANOTHER POSSIBLE SOUTION, would be to turn the graphic card off through linux. The only way I know how to turn the display off is using KDE Display Power Management but that only turns of the monitor not the graphic card.

I'd really appriciate any help, specially since I've wasted more power than one year of turning display off by compiling the kernel so many time!!!
