Logitech PS/2 Mouse Jumps in X


When I start up the gdm X system, if I move the mouse it jumps around the screen. It is a Logitech trackball, and has worked fine with other Linux distributions. I'm currently using 2.6.6.

The mouse portion of the XF86Config-4 is:

Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "SendCoreEvents" "true"
Option "Device" "/dev/psaux"
Option "Protocol" "Logitech"
Option "Emulate3Button" "true"
Option "ZAxisMapping" "4 5"
EndSection

I also get an error on the console if I move the mouse in the console:

psmouse.c: Explorer mouse at isa0060/serio1/input0 lost synchronization, throwing 3 bytes away.

Don't know if it's related or not.

Thanks in Advance,
Allen

More data-

This is not strictly a PS/2 mouse, as I have just found out by tracing the cable. This is a USB mouse with a PS/2 adapter that goes into a KVM switch (Omniview 2-port KVM switch). The KVM switch connects a Linux and a Windows machine. When I reboot, the mouse is OK in the one that is switched to (either Windows or Linux), but exhibits the "jumpy" problem on the other, whichever it is. So, this tells me it is a KVM problem of some sort, not Linux or XFree86, although it's not that simple, either (I've been experimenting between the phrase before the comma and the phrase after the comma).

In all cases, on reboot- whichever computer is selected, the mouse is OK. So, you may ask, why not reboot one, switch to the other, and reboot it? This works for Windows, boot Windows, and you can switch back and forth, and the Windows mouse stays happy. But with Linux, however, if you boot with Linux selected on the KVM, it is OK, but if you switch to Windows and back again, the Linux mouse is all screwed up again.

So, at best, every time I switch to Windows and back again, I have to reboot Linux.

Is there any way to even debug this? I'd hate to find a situation where WinDoze is more stable than Linux! Any help I could get solving it would be greatly appreciated!

Thanks in advance,
Allen

You shouln't have to reboot linux for it to work, just restartx..
Not sure if this will work on your kvm or if it just does on mine (Zonet kvm switch), but when I switch between machines I go to a tty, then I go back to X when I'm on that machine.

I have been able to unplug the mouse and/or keyboard from the KVM switch (Belkin) to fix this problem in both Linux and Windows. Before this, I had tried switching to text screen (CTRL-ALT-F2) and back to X11 (CTRL-ALT-F7), restarting the X server, but nothing worked except a reboot.
