You may need to install steam-devices to get controller support to work.

I use Pop!_OS and have had zero issues getting my Nvidia GPU to work on it, so that or a similar Linux distro that has good Nvidia driver support might be worth checking out.

Do you mean early access or advanced access?

If I need to get up at 5AM I just set my alarm and as soon as the alarm goes off I hop out of bed, to force myself to actually get up before I get the chance to start thinking about it (and postponing the getting up part).

As for what I do in the evening: if getting up at 5AM every day is my goal I just start by setting my alarm at 5, and aim to go to bed earlier. If I did go to bed late the night before, I would still set my alarm at 5 and just be tired the next day. Because the next day I’ll feel so tired I’ll automatically end up going to bed earlier. So it works itself out. So if I really wanted or needed to get up at 5AM every day I’d just do it even if I didn’t sleep enough hours the night before. Once I’m in a routine I don’t even need to set my alarm. I’ll just automatically wake up at that hour.
