Rotating Screen 90 Degress does not work after dup

Hi everyone,

I am struggling with my desktop configuration after a dist upgrade. Currently, my setup consists of 3 monitors - 2 in horizontal and one in 90 degree mode.

After the dup, changing the third monitor into 90 degree mode, does not work. The settings show the rotated monitor icon, but yet the actual monitor remains in horizontal position.

I have an AMD laptop with integrated graphics.

Is there any solution or an idea?

Gnome? Plasma? Other? What model of AMD Graphics? How are they connected? Input/output from inxi -GSaz would answer these questions. Be sure to paste the command input/output in between two rows containing only ~~~ each.

Sorry, I totally forgot to include this information.

Graphics Card: AMD Renoir [Radeon RX Vega 6 ]
Desktop: Plasma6

Here is the total output:

Current is 20240524 (and overdue for update). I’d start with at least getting current. If that’s no help, try switching the display driver from amdgpu to modesetting. Read the primer pinned to the top of the hardware forum here to find out what this means and how to switch. If that doesn’t work either, try disabling KScreen in systemsettings startup, then installing and using arandr instead to manage screen placement.

Thanks! I will try those suggestions and update this thread.

The problem simply solved itself. I was away for a few days, and was therefore unable to test the solution you suggested.

I just came back home, and now everything seems to be working, magically.
