Screen blanking and dpms can't be turned off
This is Kubuntu-11.10, all current updates applied, 64-bit.
the problem is the screen keeps blanking -- going to black every few seconds, regularly, and moving the mouse does restore the normal screen. I do not have any screensavers activated, and everything on Power save is turned off. I tried turning off dpms with:
xset dpms 0 0 0
xset dpms off
And then maybe 30 seconds later, the screen goes black, and checking with xset -q, dpms has been turned back on.
I cannot figure out how to completely disable dpms. this is extremely irritating, as I cannot work with the screen going black every few seconds. Something is turning it back on, and I haven't been able to figure out what. I set up xorg.conf to disable dpms with:
Option "blank time" "0"
Option "standby time" "0"
Option "suspend time" "0"
Option "off time" "0"
Option "dpms" "false"
After logging in, xset shows dpms is disabled, but after a few seconds, it comes back on. Is there a way to shut this off, once and for all?
