I am running LM 6.1 and have been using it for the last
6 months or so, without any problem.
The last fews days I have been having problems with
a shimmering effect on my desktop (KDE,Gnome,ect.).
For instance if I look at a border in this window there
is a very apparent sawtooth effect running all up and
down the borders. It is also quite apparent in text.
However when I exit X and go back to a terminal screen
the problem is not there, but if I start X again the
problem will reappear.
Also this problem is
intermittent, it has totally cleared up while typing
this post. Last night I was on it for 2 or 3 hours with
no problem.
This is a dual boot machine and if I boot into Windows
there is no problem.
Being an E-tech for 25 years and repairing televisons
for 18yrs it appears that something is disturbing the
timing of the horizontal scan, like a beat frequency
effect.
Any help would be appreciated.
