Hi, I just thought that I would see if anyone has any suggestions for
manually fixing this or if there is an essential comparability problem.
I used the nvidia utility to set up xorg with xinerama and TwinView so
that I could have an extended desktop over two monitors. This sseems,
however, to cause some kind of conflict with the composite and damage
extensions so that when I go to enable built in effects they cannot be
enabled as "required X extensions (XComposite and XDamage) are not
available". I tried specifically loading them in the file and that
doesn't seem to help (they are on in xorg by default anyhow I think)
There is actually a message in the load that claims they loaded but then
they don't when X is fully started and there is no log explanation about
what happened.
Oddly, this configuration also makes it so that the Display component of
systems settings crashes without loading whenever I start it. I guess
its not configured for xinerama?
Anyhow, here is my current xorg file. I turned of the twin view setting
and just left xinerama on and that seemed to make no difference at all.
