[Bug 541501] Re: [RV515] [LENOVO T60] external screen display shows "shivering", horizontal refresh offset

[Gary B]

I have something similar on my Z61m with the standard ATI card.  In my
case, if I leave the machine running for a while, after some period of
time the screen will go crazy.  I can still see what's running, and I
can carefully move the mouse and do things but it's really unusable.
Logging out does not fix it, and it also does it when I switch to one of
the virtual screens.

So far it has always happened while the machine was idle - I've been
working on another machine while I sort out the various issues with
10.04, and periodically moving the mouse on the laptop, so it's always
happened while the screensaver was running.  But I don't know that's a
requirement because the screensaver is running most of the time.

I have found that putting the machine to sleep and then turning it back
on fixes it - for a while.
