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

@sdetweil I’ve never seen that on a 3, FWIW.

@sdetweil Hi
Yes I see that as well in bullseye, that is what I mean with ‘screen configuration app’.
If I rotate it in that (to left), the monitor just goes black?
@BKeyport it’s there in bullseye, but not previous versions.

@fribse I do not know. maybe a bad HDMI cable or a bad adapter if using HDMI to DVI, or a bad monitor?

all my monitors and TV’s work in any orientation.

@fribse and is work on rpi3 to 😉

@fribse I don’t actually have a 3 with Bullseye, however, My next step would be to try the other GL drivers through raspiconfig.

[fribse]

@sdetweil That would be odd, as it works with previous versions of Raspberry Pi OS?

[fribse]

@BKeyport That is worth a try, didn’t think of that!

@fribse Hmm, can’t make this work. I can get it to work on a RPi4, but not on a RPi3 with the ‘Screenconfiguration’ app.

It’s really annoying, I would like to have screencast and remote-control modules enabled, so that Home Assistant can integrate to it, through the remote-control module, but that doesn’t work on Buster (the integration fails to set up), it fails because of some weird problem in the integration combined with the screencast, which the author can’t reproduce, which is very odd, as I can show it every time.

I can get the integration to work on Bullseye together with the remote-control module and the screencast, but not on a RPi3, only on a RPi4, and even rotate the screen, but I don’t want to place a very hot and overly powerfull RPi4 behind the magicmirror.

Damned if I do, and damned if I don’t.

@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.
