Twitter post by Daniel Feldman (@d_feldman): Linux is the only major operating system to support diagonal mode (credit [Twitter] @xssfox). Image shows an untrawide monitor rotated about 45 degrees, with a horizontal IDE window taking up a bottom triangle. A web browser and settings menu above it are organized creating a window shape almost like a stepped pyramid.

The
--rotate normal,inverted,left,right
does not work, but you can use the transform option to achieve the same effect. To create the transformation matrix you can use something like: https://angrytools.com/css-generator/transform/The final command looks like this:
xrandr --output screen-1 --transform 0.87,-0.50,960,0.50,0.87,540,0,0,1
To restore the original use (type this in first, because if you screw up you might not be able to see anything anymore):
xrandr --output screen-1 --transform 1,0,0,0,1,0,0,0,1
I tested it on x11.
