This problem was plaguing my friend's PC (which was my less newer rig), but not my new rig. Same distro, same architecture, same hardware manufacturers, mostly same setup. BUT, he was experiencing the screen off thing every 30 seconds, like clockwork.
The FiX is here! I simply went to System Settings > Power Management. Tab over to Activity Settings, and choose to define a special behavior. Check the box that says "Never shutdown the screen", and leave the other two unchecked. I waited about 2 minutes after applying it (didn't even bother to close the settings window), and the screen stayed on. Perhaps the fact that this bug resides in the KDE power management as some goofed-up timer that we cannot control is the reason why it was overridden by this checkbox. I am only one person though, so please, those of you who are still having this happen, please try this method in order to confirm my solution for everyone, which may then be turned into a workable solution until the KDE developers fix whatever is causing this thing to happen on some machines and not others. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/952521 Title: Screen blanking and dpms can't be turned off Status in “xorg” package in Ubuntu: Invalid Bug description: 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?
