Description of problem:
Mechanical switch box switching keyboard (PS/2), mouse(PS/2, Logitech
Cordless Mouseman Pro) and display. After switching to the other PC and
back the mouse input is lost rendering the switch box virtually useless.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Switch to other PC
2. Switch back
Actual Results: Cursor frozen at one spot.
Expected Results: Cursor following mouse movements
The problem appeared after upgrading the kernel 2.4.2-2 to 2.4.9 and the
glibc to glibc-2.2.4-19.
Mouse can be recovered by the screen test in the Xconfigurator.
Red Hat Linux does not officially support using KVM switch boxes. Many
of these devices work fine, while others do not. Some of the problems
are software related, and some are the actual devices themselves. Since
we do not have all of this hardware, we cannot actively support it.
I'd also like to add, that 99.99999% of all KVM related bugs, are the
KVM itself causing the problem. It is rarely if ever a software problem.
