    You need to edit the touch matrix. Full tutorial here https://www.gechic.com/en/raspberry-pi-touch-monitor-rotate-touch-screen-rotate-settings/ but it’s usally done by editing your40-libinput.conf in /etc/xorg.d.

      @Manino You have to do a couple of things. The best explanation is here. Basically, find the name of your monitor, and then do this command in terminal:

      xinput set-prop ‘name of your device’ ‘Coordinate Transformation Matrix’ 0 1 0 - 1 0 1 0 0 1

      This will rotate the touch controls to the right (depending on which way you turned your monitor, this might have to be adjusted). The only problem is that I haven’t found a way to make it permanent (in Raspbian), so it reverts every so often and you have to run the command again. I’ve written it to etc, but it doesn’t take. If anyone has any suggestions for permanence, I’d love to hear it.

        @viktorzonix Wow! Thanks for this. In my searching a couple of years ago, this never came up and nothing else ever had the correct info. I had just lived with the fact that I had to keep re-entering it periodically. Woo hoo!

            @sdetweil Driver was only for Windows. I have buttons on the screen, but could’nt choose to rotate screen. All text was black except the one for rotate that was grey.

            Maybe it’s because of this, found in the Dell manuall : NOTE: “Horizontal Position and Vertical Position adjustments
            are only available for “VGA” input.”

            I’m using HDMI. I don’t even know if the VGA would have solved my problem. But no need to know, @viktorzonix solved the problem for us. So glad for u guys helping, I haven’t asked one question at MM forum and not getting helped.
