This happens with both the Belkin Omni View SE 4 port kvm switch and the Belkin Omni View Pro 16 port kvm switch.

I have recently added an Iogear KVM switch. My XP system works O.K, but my RedHat 8 system has a problem with the mouse. The mouse will not work in X or gpm. This seems to be the same problem described in bug 77545. I have more info for this bug. I have tried several different mice. Both two button and three button. No wheel mouse tried. I have tried the following Linux versions. RedHat 8, with the default Kernel and latest Kernel: gpm sees no mouse, XFree86 sees no mouse. Boot messages indicate PS/2 mouse found, but mouse movements and keys are not recognized. RedHat 7.2 gpm sees no mouse, XFree86 sees no mouse. Boot messages indicate PS/2 mouse found, but mouse movements and keys are not recognized. RedHat 6, Kernel 2.2.5-15 gpm- mouse works, XFree86- mouse works. All Linux run on same hardware, just different hard drives. Looks like updates to mouse support in 7.x Kernel removed support for KVM switches.
I have a DELKIN 4-port KVM switch. it works perfect with Red had linux 6.1. It's mouse functions cann't work well with Red had linux 9, The monitor and the keyboard are working OK, when running with Red had linux 9, I switch to other computer, and switch back again, the linux get confused with the moving event and left click event. the right click event is working OK. If I restart the linux, and never switch, then it is working ok.
I upgraded to RedHat 9 and now my KVM switch works as expected.
