I spent hours trying to set up the GUI and couldn't get it to work. Tried the AUR, Flatpack etc and no luck. In the end I just set up the command line version of open VPN with an Alias.

Yeah it's a bit of a nightmare. If you want to play the base game without any mods, I think it should work fine just using Proton GE now. But if you want the HD texture pack you have to jump through so many hoops.

I imagine in a few months the process will be streamlined, but this seems to be the only way to get it working at the moment.

Is there any reason to switch from Bitwarden now? I heard Proton Pass was pretty bare bones at launch, but how has it come on in the past year? I currently use the rest of Proton's suite but not Proton Pass as Bitwarden was better when Proton Pass originally launched.
