Rotate klipper HDMI Display 180° (SV08)

Hi i am a HDMI display and I want to rotate in 180°, because of my wiring.
i already tried the aproach from the klipperscreen docs.:

but unfortunately it does not work.

The display identifier is displayed with the name “default”
when executing this command: “DISPLAY=:0 xrandr”
I get:
"
Failed to get size of gamma for output default
Screen 0: minimum 1024 x 600, current 1024 x 600, maximum 1024 x 600
default connected 1024x600+0+0 0mm x 0mm
1024x600 0.00*
"

Executing this command.:
“xrandr --output default --rotate invert”
results in.:
“Can’t open display”
or with the enviroment variable set (“export DISPLAY=:0”) in.:
"output default cannot use rotation “inverted” reflection “none” ".

I already updated my firmware, as well as Klipper.

Any ideas?

Here for THE EXACT SAME THING.
xrandr returns the screen as default. When connected to my linux machine the same screen returns HDMI-1.
I have also followed the directions as detailed on klipperscreen.readthedocs.io with no results.
In my case, I am trying to utilize an Odroid VU7+ I had left over from an older project.
The screen displays perfectly, but has the wrong orientation and currently no touch.
I have attempted to update klipperscreen, but not the firmware nor Klipper

HDMI-1 connected 1024x600+2560+0 (normal left inverted right x axis y axis) 150mm x 100mm
1024x600 43.07*+

output from my linux laptop

I reviewed the docs on xrandr --help and tried every combination I could come up with.
the vast majority return that the display cannot be opened

I also changed default into HDMI-1

        Identifier "HDMI-1" #previously default
