Thanks to Carlos Garnacho’s recent work with the evdev driver and Gtk+ along with Peter Hutterer’s work on getting  the multitouch situation sorted out inside of X, not to mention everybody else who has contributed to the effort, I was able to get Multitouch working on my Fedora 13 powered Lenovo T410s.

All the following instructions relate to those who have N-Trig multitouch devices. Mileage may vary with other devices. To start playing around with multitouch in Fedora today you will need

  • my evdev multitouch RPM packages built from Carlos’ branch
    • Warning: this package obsolete xorg-x11-drv-evdev so you will no longer get updates from the Fedora repo
    • Note: I’ll provide a yum repo for my packages once Koji is up and running again, for now if you don’t have an X86_64 machine you will need to rebuild the source rpm.
  • If you have a N-Trig device you will also need to get the kernel Kyle built which has a fixed N-Trig driver (hopefully this will show up in an update soon).
  • You will also need Carlos’ xorg.conf snippet. This is again for the
    N-Trig driver but should be easily modifiable for other devices
  • To play with multitouch you will need the latest Gtk+ from the xi2-playground branch

I recommend building Gtk in a jhbuild environment or at least don’t install it since it is the unstable 3.0 branch. Once the multitouch stuff has been backported to 2-20 branch I will start providing packages. I take no responsibility for the breakage of anyone’s machine due to replacing such a major system package. Thankfully, if you run inside of jhbuild you can play around all you want without fear of breaking your system. Another option might be to run inside an virtual machine but I am not sure if multitouch events will propagate correctly yet.

If you want to play with some demos you will find them inside the tests/multitouch directory of Gtk. Have fun and ping me with any issues you have. It might be nice if we got this working for Fedora 14. The pieces are certainly falling into place.
