how to uninstall PITFT plus software on a RPi 3B+
I'm about to install PITFT plus display software with adafruit-pitft.sh script. I'm going to make some tests with console-only and graphics display mirroring and would like to know in advance how to uninstall it completely and revert to HDMI-only setup

Re: how to uninstall PITFT plus software on a RPi 3B+
More specifically. If I look at adafruit-pitft.sh script:
and mirror displays, there is no chance to restore HDMI default since uninstall_fbcp isn't invoked. Only way would be to install console on the PiTFT display and then rerun and answer no to both questions. Perhaps a modified script like:
would do the job?
Code: Select all
# ask for console access
if ask "Would you like the console to appear on the PiTFT display?"; then
info PITFT "Updating console to PiTFT..."
uninstall_fbcp || bail "Unable to uninstall fbcp"
install_console || bail "Unable to configure console"
else
info PITFT "Making sure console doesn't use PiTFT"
uninstall_console || bail "Unable to configure console"
if ask "Would you like the HDMI display to mirror to the PiTFT display?"; then
info PITFT "Adding FBCP support..."
install_fbcp || bail "Unable to configure fbcp"
if [ -e /etc/lightdm ]; then
info PITFT "Updating X11 default calibration..."
update_xorg || bail "Unable to update calibration"
fi
fi
fi
Code: Select all
# ask for console access
if ask "Would you like the console to appear on the PiTFT display?"; then
....
else
....
if ask "Would you like the HDMI display to mirror to the PiTFT display?"; then
....
else
# ADD AN ELSE ALTERNATIVE
uninstall_fbcp || bail "Unable to uninstall fbcp"
fi
fi

Been trying to figure out this same thing, Ideally would like the option to switch back and forth between the TV/ monitor and the TFT. Was under the impression that the easy install script did that but it's proving to not be the case

This really should exist.
The script provided in this tutorial does it:

In general, just run the script again and select different options.
