About Weylus

Weylus lets a tablet or smartphone function as a graphic tablet or touch screen for a computer. It can control the mouse pointer, mirror the screen to the tablet, accept input from a physical keyboard connected to the tablet, and use hardware-accelerated video encoding. On Linux it adds stylus pressure and tilt, multi-touch, capture of specific windows, and use as a second screen.

The tablet needs only a modern browser, while the computer runs Weylus and connects over the local network through a displayed URL or QR code. There is no encryption, so it should be used only on trusted networks, on-screen keyboards are not supported, and Linux requires extra setup to enable uinput for pen and touch features.

Weylus FAQ

How do I connect a tablet to the computer?
Start Weylus on the computer with an access code, then open the displayed address and port on the tablet browser. If a firewall is running, ports for the webserver and websocket connection must be open.
Can I type with the tablet's on-screen keyboard?
No. Weylus supports physical keyboards connected to the tablet, but on-screen keyboards are not supported due to technical limitations.
What is needed for pen pressure and multi-touch on Linux?
/dev/uinput must be writable by Weylus, which requires additional permission setup described in the documentation.
