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: angrytools.com/css-generator/transform/

• for translateXY enter half the screen resolution
• don’t copy the generated code, it has the numbers in the wrong order just type out the matrix row wise.

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.
