Hi,
Apologies for the semi-offtopic message but ever since support for
Synaptics' absolute mode went in many people complained that it
broke GPM.
I did some work on extending evdev support in GPM, the new protocol
implementation supports following subtypes:
1. relative device - standard relative device like generic PS/2 mouse
reporting via /dev/input/eventX
2. absolute device - touch screens and tablets.
3. touchpad - device reporting absolute coordinates and pressure via
/dev/input/event, GPM recognizes normal and corner tapping.
4. synaptics - same as touchpad but also supports multi-finger taps
(expects MSC_GESTURE messages from the kernel).
Kernel has to support EV_SYNC for touchpad and synaptics support,
relative and absolute modes can be used with 2.4 kernels by specifying
nosync option.
You will find the patches at:
http://www.geocities.com/dt_or/gpm/patches/
RPMs (binary and source) built on RH8 are at:
http://www.geocities.com/dt_or/gpm/RPMS/
The README is at:
http://www.geocities.com/dt_or/gpm/gpm.html
The patches work pretty well for me and I hope they will work for others too.
Because of limited hardware I could not test evdev with touchscreen or a
tablet.
Dmitry.

Could you put a cumulative patch up as well?
Thanks,

You should not need any options for this - it's all queryable via ioctls ...

Done, along with implementing new type "auto" which selects best mode for
the device.

Cool.
You could even make it search for all mouse-like input devices ...
