Raspberry Pi 5 — Boot Straight Into Portrait Mode?

Raspberry Pi 5 — Boot Straight Into Portrait Mode?​

Does anyone know the best way to make a Raspberry Pi 5 boot directly into the correct portrait orientation under Wayland?

My Dell monitor is mounted in portrait, but occasionally the Pi boots with the orientation wrong. At the moment I correct it with:

wlr-randr --output HDMI-A-2 --transform 270

That works perfectly and also gets the mouse coordinates lined up correctly.

What I'm wondering is whether there's a proper way to set the 270° rotation permanently at boot, preferably at the display/Wayland configuration level rather than running wlr-randr afterwards.

I'm using a Pi 5 with a Wayland desktop and the display is HDMI-A-2.

Has anyone set something similar up, and if so, what's the recommended way of doing it?

Just confirmed this with another full reboot after removing the wlr-randr command from my kiosk startup script.


The Pi 5 now boots directly into the correct portrait orientation using the Kanshi config, and the mouse mapping is correct as well.


So that's solved.


Nice to finally have the portrait orientation handled properly at startup rather than using a command after boot.
