Continuing Xinerama issue

[Kevin Oberman]

I have been continuing to try to track down my issue with Xinerama on my
primary desktop since I installed xorg-7.3. It is really making it hard
to work!

The problem: I have two screens. When X starts, windows are created in
both screens and all looks as it should, but, if I move my cursor from
screen 0 to screen 1, it can't be moved back to screen 0. I have now
confirmed that this is an X issue as I can move my .xinitrc aside, start
Xorg and it fails over to vanilla X with twm and the problem persists.

I have only seen one other complaint about this, but I can't believe it
won't hit quite a few other people as dual screen systems are pretty
common and I suspect most use Xinerama.

I would love any suggestions on how I can try to track this down but I
know almost nothing about the internals of Xorg. I just use it (or try
to).

For the record:

started with -ignoreABI.
