Mtrack driver on Cosmo communicator

You can get the touchscreen working as a tracking with relative positioning (you click and drag on the screen to point where you want instead of touching where you want).

  • Right click with 2 fingers.
  • Scroll with 2 fingers work.

Steps

  1. Install the binary
sudo apt install xserver-xorg-input-mtrack
  1. Edit /usr/share/X11/xorg.conf.d/10-evdev.conf
# Catch-all evdev loader for udev-based systems
# We don't simply match on any device since that also adds accelerometers
# and other devices that we don't really want to use. The list below
# matches everything but joysticks.
