When I try to do it on Linux, every time I type < it gets replaced with >. So I can't do symbols or colors etc. I tested on my desktop Xubuntu (fails), steam deck (works fine using virtual keyboard), and windows 10 pc (works fine).
I am using a standard generic 105 key keyboard, the < key works elsewhere.
No Man's Sky works great on Linux Mint. I've been playing it for a few years via Steam with Proton. Runs flawlessly on my system. Definitely worth checking out proton.db to see if there are any tweaks you may need to make, though. Enjoy! It's a fantastic game!
