Hello. I'm having a strange problem with X 4.0.2 (woody) and my Energy
Star compliant Sony monitor. I've configured X to use DPMS to turn off
the monitor after 10 minutes of inactivity with the following line in
XF86Config-4:
Option "DPMS"
Option "OffTime" "10"
After the specified period of inactivity, the monitor appears to turn
itself off, but things get a bit weird. After some time (a minute or
two) the monitor clicks as if waking up, and the power indicator
switches from solid orange to flashing orange/green. Logging in to the
system from another machine and using xset to get the status of the
monitor (yes, I'm talking to the right X server ;^) indicates that DPMS
is disabled. Huh? It was enabled before! using 'xset dpms 0 0 600' or
'xset dpms force off' turns it off for a little while, but then it
reverts to its weird behavior again.
Until today I had power saving enabled in the system BIOS, but in an
attempt to isolate the problem I turned it off. The symptoms remain
unchanged, though.
Has anybody else seen such a thing? I don't remember it happening with
X3 under potato, but it's possible that I wasn't looking when it did.
Thanks.
noah
