How to get rid of the 10 minutes Blank Screen screensaver ?

January 27, 2007

You might not have noticed when you never happen to idle on your kubuntu more than 10 minutes, but a Blank Screen will be triggered. Not that embarassing you might think as there’s a big chance you’re away but well if there’s screensaver settings, it’s to configure that… And it becomes really irritating when you have a pctv card watching tv and that you have to move the mouse every 10 minutes.

So I couldn’t understand why this BlankScreen would appear although my settings in Desktop (right-click) / Configure Desktop / ScreenSaver was clearly using fireworks screensaver after 15minutes, and even after disabling it, I would still see this bloody BlanckScreen popping up. I thought it could be the Energy optimization from System Settings / Monitor & Display. But this one was set to 1 hour.

After some browsing on the net and some unsuccessful tries (with xset …) I thought I found it… in Desktop (right-click) / Configure Desktop / ScreenSaver / Blank Screen, unsetting the Start Automatically

Blank Screen Disabled

But that wouldn’t work either, finally I found a trick to disable this behavior thanks to ubuntu forum. In fact the problem appears when you run beryl with Xgl as a session on display :1. You’ll need to edit /etc/X11/xorg.conf and add at the end :
# To prevent Blank Screen from popping up every 10 minutes
# when xgl is run as a session on display :1,
# when all the power management settings
# you normally find only concerns display :0
