[Bug 952521] [NEW] Screen blanking and dpms can't be turned off

[Launchpad Bug Tracker]

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
xset -dpms

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:

Section "ServerFlags"
        Option "blank time"     "0"
        Option "standby time"   "0"
        Option "suspend time"   "0"
        Option "off time"       "0"
        Option "dpms"           "false"
EndSection

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?
