The PS/2 mouse driver `psm' under 2.2.1 is expected to be more robust than the ones in previous versions, but,... Well, your system seems to be proving otherwise. To verify that the X server and the mouse are out of synchronization, please do the following when your mouse behaves erratically next time: 1) Switch to a vty by pressing Ctl-Alt-Fn, leaving the X session in the background. 2) Then, go back to the X session again. If your mouse starts working at this point (even though it may go crazy again after a short while), we can conclude your system has the sync. problem. Then, the following configuration option may improve your situation, (but may not completely eradicate the problem): options "PSM_CHECKSYNC" Add the above line to your kernel configuration file, rebuild the kernel, and see how it fares. Please refer to the handbook (/usr/share/doc/handbook) on how to rebuild the kernel. You may see messages like below in the console (vty0). psmintr: sync. bit is off (XX). >The mouse is at 0x60, IRQ 12 as usual and conflicts with >no other device as best as I can tell.

The protocol must be "ps/2" regardless of the brand of your PS/2 mouse. BTW, which brand of PS/2 mouse are you using?
