How can you do fractional rotation? Does it only work with x11 or is it also supported in wayland?
I was looking into this earlier to try fixing a display that was being offset on an old tv screen. The display was going off the left side of the TV, causing a black bar on the right side.
I was trying
xrandr
, and fixed it somewhat by offsetting the display back, but somehow it did not fix the right side - it seemed as if the display had went under the black bar.But yeah you can offset, stretch, skew and rotate with
xrandr
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.
