display_rotate=1 #1:90; 2: 180;  3: 270

Save and reboot

sudo reboot
Touch rotate

Raspbian doesn't support touchscreen rotate as display, therefore, we need to rotate touch separately.

sudo apt-get install xserver-xorg-inout-libinput
  • Create xorg,conf.d directory
sudo mkdir /etc/X11/xorg.conf.d
  • Copy 40-libinput-config file to the folder created
sudo cp /usr/share/X11/xorg.conf.d/40-libinput /etc/X11/xorg.conf.d/
  • Append setting statements to 40-libinput-conf file
sudo nano /etc/X11/xorg.conf.d/40-libinput.conf
