I'm trying to configure display rotation with the xrandr and transform mouse coordinate axis accordingly with the xinput in EndeavourOS with i3-wm v4.22 running on a VirtualBox 7.0.6. While the monitor rotation works perfectly, the transformation of mouse coordinate axis is not applied to mouse movements: the mouse keeps moving exactly the same as it was before the change. However, when I try to select something in the terminal, it is selected in a wrong place, not where the mouse pointer is. When I move the mouse up/down it is moved right/left in the rotated display preserving the initial configuration for the normal display position.

The commands I used

xrandr --output Virtual1 --rotate left # works correctly
xinput set-prop "VirtualBox mouse integration" "Coordinate Transformation Matrix" 0 -1 1 1 0 0 0 0 1

How can I apply coordinate transformation to mouse movements on the rotated display? My problem is that the xinput command does not affect mouse movements at all (not the correct values of the transformation matrix).

Thank you!

  • Are you sure it's this prop and param? Try doing `xinput list-props` once to see if the coordinate transformation actually takes place. – Manas Singh May 30 '23 at 19:11
