Sometimes OpenTabletDriver crashes hard. This is usually caused by a bug in OpenTabletDriver. Due to the crash, it will be impossible to retrieve the logs from GUI. In this case, you can find a partial log in the following locations:

OS Location
Windows %appdata%\OpenTabletDriver\daemon.log
Linux ~/.local/share/OpenTabletDriver/daemon.log
macOS ~/Library/Application Support/OpenTabletDriver/daemon.log


The output from daemon is the log.

On Linux when running daemon via systemd service, the log for daemon is recorded by systemd. To view the log, run journalctl --user-unit opentabletdriver.service.
