Emerge

Touchscreen requires inputtattach program from the following package.

root #emerge --ask games-util/joystick

Fingerprint reader is recognized by the following library.

root #emerge --ask sys-auth/libfprint

Configuration

Finger/Pen Input

The following program has to be running for the functionality to work.

root #inputattach -w8001 /dev/ttyS0

For X11 to work with finger/pen input, pull in x11-drivers/xf86-input-wacom by inserting wacom argument into the indicated variable in the file shown below and run the following command for the configuration to emerge.

FILE /etc/portage/make.conf
INPUT_DEVICES="... wacom"
root #emerge --ask --deep --newuse @world
