Public bug reported:
I'm remotely logged in to a machine that has been idle for a while and
where DPMS should have turned the monitor off, and xset says it has done
so:
$ xset q
...
DPMS (Energy Star):
Standby: 300 Suspend: 360 Off: 420
DPMS is Enabled
Monitor is Off
But the monitor is on.
The xorg.conf is appended. Nothing out of the ordinary. (The AGPmem
option is necessary to render DVDs fullscreen without banding or other
evil effects.)
I tried the vesa driver on the same machine. DPMS works with the vesa
driver (but decoding DVDs is horribly slow of course).
This is on kubuntu 9.04, with a considerable number of X server
