The mouse is moving erratically. Whats wrong?
Most likely, you’ve specified the wrong protocol for the mouse. Note that newer Logitech mice do not use the “Logitech” protocol, but instead use “Microsoft” (or “MouseMan”) protocol. —————— From: XFree86 FAQ Subject: Q.C6- New Microsoft serial mouse protocol 2.1A mice don’t work. This should not be a problem with XFree86 3.3.2 and later. For earlier versions running under Linux, the solution is to get gpm-1.13 (or later), run it as “gpm -t pnp -R”, and configure XFree86 for “MouseSystems” Protocol with “/dev/gpmdata” as the device.
