Touchscreen Support

GRX ships with a touchscreen calibration utility called grx-calibrate-touch (under tools/ in the source code).

Simply run...

grx-calibrate-touch

...and follow the instructions on the screen. This will output a udev rules file that needs to be saved to /etc/udev/rules.d/. A clever person might run...

grx-calibrate-touch | sudo tee -a /etc/udev/rules.d/99-libinput.rules

...to do this in a single command.

Under the hood, we are using libinput from Wayland/Weston. This udev rule will be compatible with anything else that uses libinput. See https://wayland.freedesktop.org/libinput/doc/latest/udev_config.html for more info.
