Strange GPM behavior

[Craig McPherson <craigm@bsu.dynhost.com>]

Hmm, this is a new one.

When GPM is running, the mouse will work in the console... but the mouse
cursor in X freezes and won't move.  When I stop GPM, mouse access is
lost in the console, and the X mouse cursor comes back to life.  I've
never before seen GPM cause the mouse to stop working in X... what could
cause this?

The mouse is an old three-button Logitech-brand serial mouse.
gpm.conf looks like this:

device=/dev/ttyS0
responsiveness=
repeat_type=ms3
type=ms
append="-l \"a-zA-Z0-9_.:~/\300-\326\330-\366\370-\377\""

Thanks.
