@karsten13 said in RPi 3B+ with 'Bullseye' can't rotate screen?:

/usr/share/dispsetup.sh

The created file looks different in my case.

#!/bin/sh
if ! raspi-config nonint is_pi || raspi-config nonint is_kms ; then
if xrandr --output HDMI-1 --primary --mode 1920x1080 --rate 60.000 --pos 0x0 --rotate right --dryrun ; then
xrandr --output HDMI-1 --primary --mode 1920x1080 --rate 60.000 --pos 0x0 --rotate right
fi
fi
if [ -e /usr/share/tssetup.sh ] ; then
. /usr/share/tssetup.sh
fi
if [ -e /usr/share/ovscsetup.sh ] ; then
. /usr/share/ovscsetup.sh
fi
exit 0

I configure my MM with ansible. All old settings via /boot/config.txt don’t work anymore with my RPi3 B+ and Bullseye.
Using dispsetup.sh is the only working solution.

I also had to set this in /boot/config.txt:

...
# Enable DRM VC4 V3D driver
#dtoverlay=vc4-kms-v3d
...
[all]
dtoverlay=vc4-fkms-v3d
