During my attempt to port maemo to the librem5, I've written a program
and a script to automate this.

This program let's you execute a script if a randr event occurs, and
exports the event object properties as environment variables:
https://github.com/Daniel-Abrecht/onrandr

To see the available environment variables the `onrandr` program sets,
you can use the `env` command like this:
```
env -i DISPLAY="$DISPLAY" ./onrandr -- sh -c "echo; env"
```

On the librem5, I have this script to automatically fix the touch screen
rotation:
https://github.com/Daniel-Abrecht/image-builder/blob/master/rootfs-overlay/librem5/etc/X11/Xsession.post/70-map-touchscreen

Just replace the "generic ft5x06 (f0)" with whatever the touch screen is
called on the pinephone.

Last time I tried, I wasn't really able to use it in portrait mode,
though, because it rotated back all the time.

Daniel Abrecht
