rot8

automatic display rotation using built-in accelerometer

Automatic rotate modern Linux desktop screen and input devices. Handy for convertible touchscreen notebooks like HP Spectre x360, Lenovo IdeaPad Flex or Linux phone like Pinephone.

Compatible with sway and X11.

installation

packages

Available in:

Arch User Repository: rot8-git

Void Package: rot8

manually build from source

Rust language and the cargo package manager are required to build the binary.

$ git clone https://github.com/efernau/rot8
$ cd rot8 && cargo build --release
$ cp target/release/rot8  /usr/bin/rot8

$ cargo install rot8

usage

For Sway map your input to the output device:


$ swaymsg input <INPUTDEVICE> map_to_output <OUTPUTDEVICE>

Call rot8 from sway configuration file ~/.config/sway/config:


exec rot8

For X11 set Touchscreen Device


rot8 --touchscreen <TOUCHSCREEN>

This will start the daemon running, continuously checking for rotations.

There are the following args (defaults):


--sleep                 // Set millis to sleep between rotation checks (500)
--display               // Set Display Device (eDP-1)
--touchscreen           // Set Touchscreen Device X11, allows multiple devices (ELAN0732:00 04F3:22E1)
--keyboard              // Set keyboard to deactivate upon rotation, for Sway only
--threshold             // Set a rotation threshold between 0 and 1, higher is more sensitive (0.5)
--normalization-factor  // Set factor for sensor value normalization (1e6)
--invert-x              // Invert readings from the HW x axis
--invert-y              // Invert readings from the HW y axis
--invert-z              // Invert readings from the HW z axis
--oneshot               // Updates the screen rotation just once instead of continuously
--version               // Returns the rot8 version
