I would like my laptop's LCD panel to switch itself off automatically
after a few minutes of inactivity.
The /etc/kbd/config file specifies:
The /etc/init.d/console-screen.kbd.sh script appears to issue a setterm
command with the above options a boot time, yet nothing happens.
I issued the corresponding "setterm" command manually also to no effect.
Is there something that I need to configure in the linux kernel?
Is this a limitation of the frambuffer console with the atyfb driver?
Manually executing "vbetool dpms off" does the trick, so it doesn't look
like this is a hardware limitation per se.
The video card is an ATI Technologies Rage Mobility P/M AGP 2x (rev 64).
