(Usually the sensor is between 1-16) Secondly, what is a 4 way scroll key, as it is not implemented as 4 buttons?

My notebook does not yield a /dev/ps2 device, > only /dev/psaux and /dev/mouse (which is symlink to psaux). The touchpad uses ps/2 protocol unless put in special mode. So I ask what if it also happens if you start gpm -t ps2 -m /dev/psaux. (You need to reset the touchpad by powering down, as gpm does not put the touchpad in ps2 protocol mode when stopping.). I ask to find out whether it is general gpm fault or a synaptic specific problem. >>> The problems I experience are as follows; >>> 1: access consoleusing <CTRL><ALT><F1> and return to X using >>> <CTRL><ALT><F7> no response from X for either mouse or keybaord. >>> This happens 100% of the time with gpm 1.20.0 and only happened once >>> with gpm 1.19.6. >>> After this I must restart the system.

If you do not know how to do this, then when it happens try restarting gpm with -t ps2 -m /dev/psaux instead. The mouse will work if the touchpad is reset (to ps2 protocol). If not could you repeat 4-5 lines of what is logged, as I want to see whether it is synpatic data, that just is out of sync.
