Just got Elite Dangerous running today on my fresh Ubuntu. Loaded the modules for the z52 hotas, copied my bindings from my windows instance and there she flies. That makes 3 out o3 for my most played games in Ubuntu.
So far ED is running flawlessly. I need an equivalent for ED market connector though. But that can be manual gor the moment.
There was a flatpack release for the ED market connector awhile ago, I have no idea if it's still functioning (i have gotten in the habit of doing it manually too) but you might want to check it out. https://flathub.org/apps/io.edcd.EDMarketConnector
