For some reason I didn’t include this in my original comment, but to install the flatpaks of .NET 6 and mono 6, you’ll need to use the terminal. Here are the commands I used:

flatpak install flathub dotnet6
flatpak install flathub mono6

I had an absolute mess of a time trying to get Unity working on Linux. Even once I got it working, it had an issue where hovering over the Burst menu would cause the whole OS to lock up and I would have to reboot. It wasn’t a good experience. I’ve never used Wine so I don’t know if that would be any better.

When I first got it working, I wrote down the steps I took. I don’t know if this is everything I had to do or if I forgot a step, but it might be a good starting point.

• Install Unity Hub from the Pop!_Shop. I vividly remember not being able to get it to work right any other way.
• Install .NET and Mono via flatpak. I wrote down that it had to be version 6 of both SDKs, don’t remember why.
• Install the flatpak version of Visual Studio Code. You can do this from the Pop!_Shop if you want.
• Get the C# extension for VSC if you don’t have it.
• Once in Unity, go to “Edit/Preferences/External Tools” and check “Generate .csproj files for:”
  • Embedded packages
  • Local packages
  • Registry packages
  • Git packages
  • Built-in packages
• Click “Regenerate project files”
• When you open a script, Unity will tell you to set “Omnisharp: Use Modern Net” to false in VSC’s settings. Do this to get code suggestions.

I hope this helps! Welcome to Linux! If you need clarification on any of this, just ask.

Here are some tips from somebody who made the switch about a year ago. My advice is to take it slow.

I first tried Linux on an old laptop that nobody was using anymore. I messed around with it, did a coding project, tried to see what it was like to get this and that running. It’s good that you tried Linux with a home server first. That means you’re already decently comfortable with it.

I recommend starting with a dual boot setup. Some time later I got a new PC, and I was planning to run Linux on it. It came with Windows 11. I wasn’t comfortable with going full Linux, so I split the 512GB SSD down the middle and gave most of the 2TB hard drive to Linux. This has served me very well. It gave me peace of mind to know that if there was something I really needed that I couldn’t get working on Linux, I could boot into Windows.

After a bit, I defected back to Windows. It ended up being somewhat bad timing. I wanted to play Sonic Frontiers, but it barely worked on Linux. At the time I was also using the game engine Unity, which was what my game design courses were teaching me, and I couldn’t get it working properly on Linux for the life of me. I kept my Linux partition in case I ever wanted to use it for something or even switch back. This is partially why I recommend a dual boot setup. You might be dissatisfied with Linux the first time you try it, and if you end up really wanting to go back to Windows, you’ll be glad that you left yourself an easy way back.

Well, I’m glad I left my Linux partition on there, because I eventually came back and stayed here. I was over Frontiers, and I finally managed to get Unity working, so there I stayed. As I spend more time with Linux, I get more and more comfortable with it. I only ever boot into Windows to play multiplayer games with my friend since I don’t want to waste time troubleshooting a game for an hour during a call if something doesn’t work. Though I suspect that most of what we play would work fine on Linux! I’m starting to feel like I’m getting comfortable enough with Linux that if I wanted to get rid of my dual boot, I could. It helps that Unity destroyed itself so I don’t want to use it anymore anyway. Moral of the story: Don’t feel like you have to fully commit to Linux at first. You can make the transition slowly and do what makes you comfortable, and you’ll get there eventually.

I know this comment is very long, but I want a paragraph to recommend distros. I highly recommend something Debian based for a new user. It’s relatively easy to learn compared to other kinds of distros and more stable. I recommend either Linux Mint or Pop!_OS, both of which are excellent for beginners. They’re both based on Ubuntu, which itself is based on Debian. They’re pretty similar under the hood, so it mostly comes down to which UI you prefer. I believe that Pop!_OS is a little more up-to-date with some packages, but not everyone likes its UI, and its app store is somewhat miserable. I use Pop and I adore it, but it’s not everybody’s cup of tea. If you want to try a few distros before you commit, I recommend trying them on some old device you don’t use anymore, or a virtual machine.

That’s weird. I’m able to select it. I don’t know what could be going on there.

Woah! You can make a terminal game and have people just… ssh into it and they’re playing? That’s so cool!

Very good version of Tetris! Rotating and wall kicking feel like how they should, there’s some time before the piece touches the ground and it locking into place, you have the 7-Bag system going, it’s great! Excellent job!
