Hello!
My touchpad stops working with 2.5.74.
With 2.6.0test2 I got minimal success:
If I attach an external ps2mouse while booting, I can use this one.
Until I remove it, soon the kernel (psmouse I think) tries to init
the touchpad which fails.
My questions:
1) why are you implementing drivers in the kernel?
2) what source of information do you use to program them?
3) how can I read /dev/misc/psaux in Linux 2.6 ?
3.1) howto get gpm running?
3.2) is the patch mentioned for X implemented in X cvs?

You mean it worked in 2.5.73 but not in 2.5.74?

Ask the gpm maintainer.

Vendor docs. User reports. Yes, reports from you.

Can't help with GPM, but Peter Osterlund and I have gotten his driver
working under Linux 2.6. This really is a win because now the vertical
scroll pad works -- it never did under my old configuration.
Event device support is important. Some other things are really not
helpful.

AFAIK, you can't.

Because the raw psaux device is no longer exposed to user space.

The synaptics touchpad interfacing guide. I think this link is still valid:

You have to hack gpm to add support for the 2.6 kernel driver. Until
someone fixes gpm you have to use the "psmouse_noext=1" module
option.

No, not currently. Aside from technical considerations, there is also
a license problem, because the synaptics driver is GPL:ed, which is
not compatible (I think) with the license used by XFree86. This means
that all copyright holders for the synaptics driver need to agree to
change the license, or their contributions have to be removed and
reimplemented.

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...
good evenin'

more correct it was 2.5.72.

*wonder* 'how do i get gpm running?' (look at linux.schottelius.org/gpm/)
the problem is I currently recieve _no_ data from psaux.
no init response. nothing.

and you try / want to implement whole gpm in the kernel? (without the
bugs we have....)
