Banana Pi M5 rotating the desktop

Hello,

I'm trying to rotate the desktop from landscape to portrait. Trying to do this in the display settings in the desktop does not work correctly as it only uses the top half of the screen.

 

What does work is to rotate using xrandr:

xrandr -o right

 

I'm trying to do this automatically on start up so I have written a script to call from lightdm.conf

The script:

#!/bin/sh
xrandr -o right
exit 0

 

The parts in lightdm.conf [Seat:*] that I've edited:

display-setup-script=/home/badger/screen.sh
session-setup-script=/home/badger/screen.sh

 

This works for the login screen, however it does not rotate the display.

 

Any ideas how to do this?

Thanks.

It may be working like the bananapi M3?

i dont know if adding extra rotate param to the /boot/armbianEnv.txt works:
extraargs=video=HDMI-A-1:1920x1080M@60,rotate=90

 

an other did

Section "Monitor"
    Identifier "DP-1"
    Option "Primary" "true"
    #Option "Position" "1200 360"
    Option "Rotate" "right"
    #Option "PreferredMode" "1920x1200"
EndSection

Section "Screen"
    SubSection "Display"
        Virtual 3120 1920
    EndSubSection
EndSection

Into /boot/armbianEnv.txt I've this line:

 

extraargs=drm_kms_helper.edid_firmware=HDMI-A-1:edid/720x480.bin video=HDMI-A-1:720x480M@60 fbcon=rotate:0

 

The fbcon=rotate=x permit you to rotate, the items available are 0, 1, 2, 3.

@Mechano where did you get the drm_kms_helper module? there is no candidate

apt-file search 5.19.16-meson64 | grep drm_kms_helper gives nothing. you may not be on the same kernel version

[Mechano]

You're right, in fact I see that part gets ignored and its works anyway.

Thank you SoSie and Mechano for your suggestions, unfortunately they did not work (just tested on a fresh install).

I thought fbcon was only for the console?

@Badger , have you tried to launch your script as autostart app?
