Troubleshooting
This page will have common problems and common solutions to those problems.
First Steps
The first step to troubleshooting any problem is getting the cause of the error. KlipperScreen log output will occur
in two places. Check for the file /tmp/KlipperScreen.log and look at the contents by running
cat /tmp/KlipperScreen.log or grabbing the file over WinSCP or another scp program.
If that file is non-existent, there is a problem in KlipperScreen starting up. To get the error output in this case,
run journalctl -xe -u KlipperScreen.
Common Errors
Problems occuring before the log file appears
This section will detail problems that may happen before the log file has been created. Each section will start with a relevant line from the journalctl output.

cat /etc/group | grep tty. If you username is not listed under that line, you need to add it with the following command (if you username is not 'pi' change 'pi' to your username):usermode -a -G tty pi
