No one ever asked me "Oh, are you using linux?" Even if they see that your Desktop Environment is different from what they're used to on Windows, they usually don't notice it's anything else than Windows.
You should probably go for Linux Mint. I love the Gnome Desktop environment, but you'd need to install it afterwards.
Probably go for the XFCE version of Linux mint.
Most of the DLCs are easy cash-grabs with not much value. The base-game is regularly being modified, sometimes improved, sometimes not.
They still have performance issues in late game, Multiplayer sync issues and no ability to change keybindings.
Some major quality of life features are lacking for me.
I love the game, I've been playing since release, but I wish they'd put less effort into releasing overpriced DLCs and put more effort in improving the game. I also dislike their DLC subscription model.
I had a similar issue a few years back and I fixed it by entering TTY2 by pressing Ctrl+Alt+F2 and figuring out what broke via the terminal. My issue was that xorg couldn't start because some dependencies broke after installing an update.
Damn that sucks.
I had a similar experience with adding a keyboard layout for the game Beyond All Reason. After I submitted my pull request, it took them a year to add it to the game and didn't even use my commit. At least they credited me in their own commit.
