- https://github.com/H-M-H/Weylus - Weylus uses the uinput interface to simulate input events on Linux. To enable stylus and multi-touch support /dev/uinput needs to be writable by Weylus. To make /dev/uinput permanently writable by your user, run: sudo groupadd -r uinput sudo usermod -aG uinput $USER echo 'KERNEL=="uinput", MODE="0660", GROUP="uinput", OPTIONS+="static_node=uinput"' \ | sudo tee /etc/udev/rules.d/60-weylus.rules Then, either reboot, or run sudo udevadm control --reload sudo udevadm trigger then log out and log in again. To undo this, run: sudo rm /etc/udev/rules.d/60-weylus.rules This allows your user to synthesize input events system-wide, even when another user is logged in. Therefore, untrusted users should not be added to the uinput group.
