Oh, I think that you like to create all these "hurdles" for yourself 
just to keep us entertained :-) .

All this should be available to you in either 
System>Preferences>Screensaver and/or in the 
System>Administration>nVidia X Server Settings :-) .

Aaaah...but then you ARE running an Ubuntu system contaminated with KDE, 
aren't you? :-D


PS I still think that the CRT monitor is on the way out. Some component 
cannot handle the strain and is displaying that strain by doing what you 
are seeing. Had a similar problem with one of my CRTs when I was using them.
