Hej!

I would like to use my laptop without X, only virtual consoles and screen.
But backlight should be off while I'm away (long compiler jobs). With X
it's a simple xset dpms x y z, backlight switches off after x seconds.

Without X running I can't get it to work. Tried

vbetool dpms on
setterm -powersave on
setterm -powerdown 1

The display get's blanked but backlight is still on. Any ideas what to
try next?

I'd try "setterm -blank 10", replacing 10 with the number of
minutes you want, before the screen blanks.

Well, this blanks the screen. Fills it with blank black characters. The
backlight is still full blast.

Even setterm -blank 10 -powerdown 10 doesn't disable the backlight (that's
the command laptop-mode uses). I now read that vesafb isn't capable to do
it and will try to get radeonfb working.

Using radeonfb freezes the machine when Gnome starts. I haven't tried
to let setterm disable the backlight. Switching to uvesafb proved to be
the solution: backlight can be disabled in console mode and X still works
if I'm starting it.
