I never read STIG. I have the acer tm 524 and the fact is, after a warm boo=
t,
the touchpad is not reseted correctly. Using X with ps2 is broken.
Using gpm-1.20.0 works, because of the new init function.=20
So currently i looks like
  =20
   Win->gpm->X.

As you see, there is X less experienced with and has problems, that was one
of the reaons I would like to join the work.
I think whenever a driver is added to X, we should also be able to use it.
(and vice versa)

Yes.

That's true, that's a problem. But what mouse reading programs really exist
and are used if not gpm or X ?
And those both should be able to work with a touchpad in absolut mode!

Btw, after running gpm with synps2, X is not capable of changing back to
ps2...
