Public bug reported:
This url pretty much has the exact description of the problem I have
http://forums.gentoo.org/viewtopic-t-818488-start-0.html and their
solution was to downgrade to xserver 1.6 but I don't see how to do that
with ubuntu.
I have two 8800GTS video cards and two monitors on each card. With
Xinerama enabled and moving the mouse between screens the mouse will get
stuck. At that point Xorg will increase in memory usage very quickly it
looks like a hundred megs every couple seconds. I can go to another
machine and kill Xorg then it will restart and I can use the system
again but this is very frustrating. This setup has been working fine for
a long time now but it seems that Xinerama is xorg 1.7 is just kind of
broken.
