Pi Touch Screen: Here is how to invert
Danal last edited by Danal
For those running this very popular touch screen on the D3 + Pi, you may need to mount it inverted to get the cables to route better. If so, these two changes will make both the display and the touch mouse work correctly:
- To flip the display 180 degrees:
edit (sudo vi or sudo nano) /boot/config.txt and add a line at the bottom display_rotate=2
- To reverse the mouse (both right left and up down as correct for the 180 flipped display):
create a new file (sudo vi or sudo nano) 99-libinput.conf that contains:
Section "InputClass" Identifier "libinput touchscreen catchall" MatchDevicePath "/dev/input/event0" Driver "libinput" Option "TransformationMatrix" "-1 0 1 0 -1 1 0 0 1" EndSection
Reboot and test. That's it.
P.S. There are a bunch of ways to convince X11 to reverse the mouse. The above is one of the most reliable.
