Touchscreen plugin error - root access denied

I’ve successfully installed the Touchscreen plugin, and it loads automatically upon reboot and shows a UI on the external screen. However, the UI is a grey background with a single error dialog: “Chromium can no be run as root”. The dialog offers the suggestion that if you want to run as root you need to specify “an alternate --user-data-dir for storage of profile information”

Any ideas on how I can run the Touchscreen plugin as non root (preferable), or how I can set this switch?
