I have a logitech cordless keyboard and a cordless MouseMan Optical mouse that I share between a WinXP box and a RH9 box via a data transfer switch box. When I had RH8, I had no problem with this. When I switch to the windows box and then back to the linux box, the mouse is frozen but the keyboard still works. Somehow I managed to discover that hitting Ctrl-Alt-F2 and then Ctrl-Alt-F7 brings back control of the mouse. But I'm pretty new to linux, I don't know why that brings it back. Is it something to do with my X-Windows set up? Is there anything I can do to remedy this?

You have a keyboard/video/mouse (KVM) switch?
If your running GPM it may cause these type of problems.

Sort of a KVM- but I'm just using it as a KM.
I've also tried a number of Generic mouse
and Logitech mouse selections but I get the
same effect.

It would appear that I am running this gpm.
There's a line in my process list with PPID of 1:

gpm -t ps/2 -m /dev/psaux

What's the alternative to using this? How do
I change this?

GPM is an application that allows you to use your mouse while in the console before you startx, try killing it with "kill <PID>" and see if that helps.

Nope. Killed it dead, same problem. Even tried an interactive
startup and stopped gpm before X loaded and ps -ef'd to make
sure it wasn't there. Same problem. Any other ideas?

It may just be a conflict with the switch, do you have access to another one you can test with?
