Comment 2 for bug 111786

Yes it does still happen although I have found a slightly nicer workaround. I am now running Gutsy here and if it helps here are some syslog extracts:

Reloading the kernel module with:

#modprobe -r psmouse
#modprobe psmouse

Gives the following:

Dec 11 09:19:47 len NetworkManager: <debug> [1197364787.754732] nm_hal_device_removed(): Device removed (hal udi is /org/freedesktop/Hal/devices/platform_i8042_i8042_AUX_port_logicaldev_input').
Dec 11 09:19:48 len kernel: [68553.988000] input: PS/2 Generic Mouse as /class/input/input9
Dec 11 09:19:48 len NetworkManager: <debug> [1197364788.064945] nm_hal_device_added(): New device added (hal udi is '/org/freedesktop/Hal/devices/platform_i8042_i8042_AUX_port_logicaldev_input').

and I still have no mouse cursor, but pressing reset on the kvm switch (better than unplugging but still awkward) gives:

Dec 11 09:21:06 len NetworkManager: <debug> [1197364866.597000] nm_hal_device_removed(): Device removed (hal udi is '/org/freedesktop/Hal/devices/platform_i8042_i8042_AUX_port_logicaldev_input').

Dec 11 09:21:07 len kernel: [68633.108000] input: ImPS/2 Generic Wheel Mouse as /class/input/input10

and I do get the mouse back.

If any other info would help then please ask and I'll do my best to be rather quicker responding this time.
