Having read through some of the comments I just wanted to add one thing. If you find that one distro doesn’t quite do what you need, don’t be afraid to wipe it again and install a different distro. I migrated from windows 10 to Linux mint, I found it frustrating for gaming, and then from mint I switched to cachyOS, which is built from the same OS that the steam deck uses. I haven’t had any similar issues since. Find what works for you, and don’t be afraid to try something else
