Quick question, I have tried looking through Gnome manuals and linux manuals but I haven't been able to spot anything on this.

In Gnome my screen blanks out after about 10 minutes, just as if I was at the command prompt. This isn't a screen saver or power saving through Gnome, but somethng else, as those features are turned off.

As a side note this doesn't happen with KDE as the desktop. But since I ripped out qt libs and rebuilt them, I haven't rebuilt KDE...

Any hints help would be great full, thanks..
