mouse freezes when switching between X sessions

[Robert Arkiletian via arch-general <arch-general@xxxxxxxxxxxxx>]

If I have two X sessions running on different accounts and I switch
between them (ctrl-alt-f1  ctrl-alt-f2) a few times. I usually get a
frozen mouse in one of the two X sessions. I then must shutdown that X
session and run it again (startx) to get my mouse working again in
that account.

Any ideas how to diagnose the issue, much appreciated.

Thanks
