that could be a problem..

means we _are_ obsoleted from now on...
if that's true I'll try to help you to use code from gpm where possible.
and I hope we can work together so we can use gpm once again.
(and possibly develop a buffer, which is available within
gpm and X...I am rethinking this currently)

think so, too. but in fact as my dmesg shows, the touchpad doesn't
like you..and I would like to use it :)
So, is /dev/input/mice now the general device to use?
If yes, is it imps2 or what should we talk to it?

...another brick in the .. another hack in gpm.

good hint, at least somehow I can work with X & gpm..

Btw, aren't there any 'real' alternatives to xfree86?

...or xfree86 people have to change to gpl...
