There are quite a few people having issues running ThinLinc on Pop OS. This is because we don't ship a default profile for COSMIC (basically GNOME), and it's not obvious to most people what the issue is. For better demo effect, we should ship a default profile as per: https://community.thinlinc.com/t/thinlinc-server-pop-os-22-04-lts-not-working-no-executable-profiles-could-be-found-on-this-system/510/6
If/when we do this, we should let System76 know.
