KDE might be the only program that you use which switches over the
rendering style to another rendering or compositing library or method,
which might cause the flicker and subsequently trigger the behavior in X.
Don't rush to blame the user programs just yet, because this very much
sounds like an X conflict. What driver are you using?

Finally. That did the trick. BTW, I've encountered Compiz while
testing other distros (curiosity) but I've always immediately disabled
or removed it.

I'm sure glad to get past that because I'm chomping at the bit to get
working on video (now that includes capture in Linux since I finally
got my Twinhan card to work), dvd authoring and mastering.

Yeah that did the trick. Tanks :=)

Odd. It was just the opposite for me. This is the first time I've had
to do it - 12.2 didn't need that stanza.

I'm sorry for responding this late. Both the health of my PC and of myself
decided to fail lately.
Maybe that's what you call it. I'm not very good at technical terms. But it
was very convenient. Why do you think changing the resolutio is not a good
thing? This KMag I don't like very much: it only shows part of the screen,
and always happens to be in front of the part you want to see.

I copied the relevant lines from my old xogr.conf, but that did not help.

Generally, when you lose resolution, you lose a lot of clarity and often
times, programs won't quite lay out correctly. Usually, if things are two
small to see, you can increase the font sizes that are used, and you'll
get larger text that is clearer and generally easier on the eyes. Buttons
and icons can be done this way as well. You'll be able to get the best of
both worlds that way, unless there is something specific that doesn't
work, in which case, usually KMag is enough to adjust it.

On the other hand, there should not be any problem with adjusting the
screen sizes that you have available to you. You should be able to do this
through the System Settings, and you should be able to set the system to a
screen resolution that suits you.
