Mouse will not work after X crash on CentOS 6
I have 3 CentOS servers connected to a KVM switch so I can use 1 keyboard/mouse/monitor for all 3. I replaced the monitor on the switch while everything was still up an running. I then toggled between the 3 servers on the KVM. 2 worked fine, when I got to 3, the display became garbled then went black. I ssh'd into the server and killed Xorg which promptly restarted. KVM toggle back to problem server and display appears fine but the mouse will not work. Keyboard is OK.
Tried killing Xorg again from ssh but still same problem: OK display, no mouse functionality.
Don't know what to do next. Any help is appreciated! Oh, problem server is CentOS 6, other 2 are 5 and 6.
