Error in Booting to Touchscreen Guide
I followed https://www.repetier-server.com/booting-into-touchscreen-mode-for-linux/ and struggled why on reboot the splash screen would come on then I'd get dropped to shell. I have the following in my rc.local file per the guide:
su -l pi -c "xinit ./rs -- -nocursor"
su -l pi -c "/home/pi/startserver.sh"
Turns out that's wrong. Per https://forum.repetier.com/discussion/comment/8443/#Comment_7616 it should be:
/usr/bin/xinit /home/pi/rs -- -nocursor
I made that change, rebooted and it worked fine!
