DESCRIPTION
The steam deck is a 800x1280 LCD screen source. In order to change to
orientation from portrait to landscape, Valve added a panel quirk to the Linux
kernel. However, this quirk interact with the gyro and cause the screen to
never rotate properly.
In order to test the screen rotation in KDE, you will need a patched
iio-sensor-proxy due to an upstream bug. On default, steam deck will start in
lizard mode. You will have to disable it by sending 'N' to the
/sys/module/hid_steam/parameters/lizard_mode
https://gitlab.freedesktop.org/hadess/iio-sensor-proxy/-/work_items/416
STEPS TO REPRODUCE
1. Exit steam
2. Disable Lizard mode
- echo N | sudo tee /sys/module/hid_steam/parameters/lizard_mode
3. Set Automatic to enabled in display settings in systemsettings
4. Run patch iio-sensor-proxy
1. Pull the repo
- git pull https://gitlab.freedesktop.org/hadess/iio-sensor-proxy
2. Patch the input acceleration

3. Run Meson
- meson setup build
4. Run ninja
- ninja -C build/
5. Run iio-sensor-proxy
- ./build/src/iio-sensor-proxy -r -v
OBSERVED RESULT
The orientation is off by 90 degrees due to the kernel quirk
EXPECTED RESULT
I expect the screen to be in the same orientation as any other tablet.
