Synopsys:
One of my Linux boxes runs RedHat 7.0.
One of my Linux boxes dual boots Win2k and SuSE 7.0 eval.
I also have a Win2k box.
These boxes share one monitor/keyboard/mouse via a KVM switch.
SuSE 7.0 came with Linux-2.2.16; all systems worked well together until I built myself a new kernel for the SuSE box.
I built Linux-2.4.7-ac9; everything went fine (at least, I received no error messages :-)
Problem:
When I boot to my new kernel, the mouse is dead; although the mouse "cursor" is centered on the screen. (I boot to KDE.)
The keyboard works fine, _until_ I use the KVM switch, at which point the keyboard locks up. We're talking "press-a-button to reboot".
"cat /proc/interrupts" and "cat /proc/devices" for 2.2.16 and 2.4.7-ac9 are identical.
Homework:
Searching the Linux Kernel Archives indicates that the KVM switch may be a documented problem, but I am unable to find any documented solution. (Other than "Re: mouse problems in 2.4.2" Sun Mar 25 2001, where Keith Owens suggests a script that works for him--i.e., "gpm restart" followed by "kbdrate -r 30". Fine, but as I didn't need this script before, why should I need it now? I would prefer to fix the problem, not work around it.
The mouse problem after a kernel rebuild seems to be recurring, but the only suggestion I've been able to find to fix that is to recompile the kernel. ("Re: ps2 mouse xf86config" Sun Jun 16 1996<-pretty old) Although this *was* my first kernel compilation, it's kind of hard to believe that going through the motions of recompiling would fix it.
Question:
Does anybody have a clue? Should I just recompile and hope for the best?
