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.
