Weylus, turn your phone into a touch screen for your desktop

about weylus

In the next article we are going to take a look at Weylus. This is a tool that will help us turn our tablet or mobile phone into a touch screen, allowing us to duplicate or extend the desktop screen to one of these devices. It is an application that we can find available for Gnu / Linux, Microsoft Windows and macOS.

Weylus will allow us to control the mouse with a tablet or phone, mirror the desktop screen to a tablet, and send keyboard input, all with hardware-accelerated video encoding. To use a phone or tablet as a touch screen, all we will need is to install Weylus on our Ubuntu system, have a modern web browser running on the phone, and have both the desktop and the phone on the same network..

It is worth noting that Weylus works better with X11, even though it has experimental support from Wayland. Things that don’t work in Wayland include input mapping for windows, displaying proper window names, and catching the cursor.
