RPi 3B+ with 'Bullseye' can't rotate screen?

fribse

@fribse Ok, so now I’ve gotten a second RPi3b+. Apparently the monitor doesn’t like the way that Bullseye rotate the screen (by using the ‘Screen orientation’ in the GUI).
So how do I rotate the screen in ‘the old way’ which works fine on the monitor.
My guess is that it’s modifying the refresh rate beyond the capabilities of the monitor.
It’s usually running on 60Hz, and I tried changing it to 50Hz, but that didn’t change anything.

So what do I do now? I would really like to use the bullseye, as I can’t get Home Assistant to control the mirror if I have screencast installed on the mirror under Buster.

@fribse I use a RPi3 B+ and Bullseye and I do the rotate in the boot/config.txt and it works ok for me.

I have no solution for your problem but if you use the WebUI to change screen settings in bullseye the changes are made here:

pi@pi4:~ $ cat /usr/share/dispsetup.sh
#!/bin/sh
if ! grep -q 'Raspberry Pi' /proc/device-tree/model || (grep -q okay /proc/device-tree/soc/v3d@7ec00000/status 2> /dev/null || grep -q okay /proc/device-tree/soc/firmwarekms@7e600000/status 2> /dev/null || grep -q okay /proc/device-tree/v3dbus/v3d@7ec04000/status 2> /dev/null) ; then
if xrandr --output HDMI-1 --primary --mode 1920x1080 --rate 60.000 --pos 0x0 --rotate normal --output HDMI-2 --off --dryrun ; then
xrandr --output HDMI-1 --primary --mode 1920x1080 --rate 60.000 --pos 0x0 --rotate normal --output HDMI-2 --off
fi
fi
if [ -e /usr/share/tssetup.sh ] ; then
. /usr/share/tssetup.sh
fi
exit 0

So you could play with the xrandr command, may this helps …

@N6NG Ok, and what are you writing in the config for it to work? That would be a big help for me :-)

@fribse it’s not in the mirror config. you have to change the rasperrypi’s actual configuration

fribse

@kayakbabe Yes, I’m referring to /boot/config.txt, not Magicmirror/config/config.yaml :-)

N6NG

@fribse It is in the boot/config.txt file itself. Not in the MagicMirror/config/config.js file.
Just cd /boot and sudo nano config.txt and either find the display_rotate=0 and change it to display_rotate=1
or add the line display_rotate=1 I added it under the #config_hdmi_boost=4 line but I suspect you could add it just about anywhere…

@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

@doctore Ok, I’ll try to see if that works, thankyou!
