I have not. IIRC I tried it in a VM once and it didn't boot, but in general I'm not really interested in tinkering with the OS and prefer to have something that works OOTB.

Besides, Flatpak doesn't work on BSD, and that alone is a dealbreaker since I would miss out on almost every GNOME app, while I work on a library all of those apps use. Then, I very much doubt trackpads work well on it + even support for my keyboard was only properly added to Linux kernel very recently so BSD likely doesn't support it. Not to mention tablets - and for, say, osu!lazer I need OpenTabletDriver which doesn't exist on BSD (as well as the game itself).

So overall it's one of the least practical options for me ^^
