[SOLVED] Waveshare 5.5 AMOLED HDMI Display - screen rotate

[dewen]

Use Web SSH with command
DISPLAY=:0 xrandr --output HDMI-1 --rotate right
The screen rotate to correct place.

For Touch rotate, I followed Touch Rotation from Waveshare Wiki
90 degree: Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"

My problem is, how can I add DISPLAY=:0 xrandr --output HDMI-1 --rotate right
to an autostart file when boot, so I don't need to do it again.

Thank you.
