My Kubuntu 12.04 system updated to xsetting-kde-0.12.3-0ubuntu2.1 a few hours ago. A reboot or restart of the xserver was requested. After a reboot the video display began blanking (black screen) every 2 or 3 seconds. I had to move the mouse to keep the display visible.
I opened a Konsole and issued:
xset dpms 0 0 0
and the blanking stopped. However, some video events (starting a youtube video or opening a PDF) restarts the blanking and the above command has to be repeated. Settings in the "Power Settings" option of the battery monitor have no effect.
