In addition, the KVM fails to switch to any monitor after that unless the current X was killed.

The KVM I use is : Master View(max) CS-1716

Sorry about the phenomenal bug spam, guys.  Adding xorg-team@ to the QA contact so bugs don't get lost in future.

It can't reproduce on both our Master View(max) CS-1716 and Master View(max) CS-1758 now.
When I switch the KVM to monitor A instead of drect connection, X screen can also display.
