# rot8
[](https://github.com/efernau/rot8/actions/workflows/rust.yml)
## automatic display rotation using built-in accelerometer
Automatically 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 [X11](https://www.x.org/wiki/Releases/7.7/) and Wayland
compositors which support the `wlr_output_management_v1` protocol (Like
[sway](http://swaywm.org/) and [hyprland](https://hyprland.org/)).
### installation
#### packages
Arch User Repository: [rot8-git](https://aur.archlinux.org/packages/rot8-git/)
GNU Guix Package: [rot8](https://packages.guix.gnu.org/packages/rot8/)
Nixpkgs: [rot8](https://search.nixos.org/packages?show=rot8&type=packages&query=rot8)
Void Package: [rot8](https://github.com/void-linux/void-packages/tree/master/srcpkgs/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
```
or
```
$ cargo install rot8
```
### usage
Map your inputs to the output device as necessary. e.g. for sway:
```
$ swaymsg input map_to_output
```
Call rot8 from your compositor configuration. e.g. for sway:
```
exec rot8
```
For X11 set Touchscreen Device
```
rot8 --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
--beforehooks // Execute a custom script before rotation
--hooks // Execute a custom script after the rotation has finished
--version // Returns the rot8 version
```
You may need to play with the normalization factor (try multiples of 10) and the axis inversions to get the accelerometer readings to calculate right.
