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.
Available in:
Arch User Repository: rot8-git
Void Package: rot8
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
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
--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.
