Re: turning off screen

[prayner unimelb edu au]

I got to the bottom of this.
to summarize it was an interesting interaction between aspects of the
intel i915 video driver on my system and vbetool.
With the default boot vbetool would not work, to turn off the screen,
nor would
setterm -blank force
Adding the kernel option nomodeset in grub.conf fixed that problem but
also meant that X would not boot
running
rmmod i915
then
modprobe i915 modeset=1
left both vbetool and X working as hoped.
Probably setting modeset=1 on the kernel option would work.
I suspect this problem will not touch all drivers but if you do run
across it this is one thing to try.
regards
Peter
