Which distro do you use? Most distros have their own dedicated chat rooms, and it could be on Discord, Matrix or IRC, with IRC typically being the one with most users.
Eg for Arch Linux: #archlinux on irc.libera.chat
or for Fedora: #fedora-workstation on irc.libera.chat
I had a really nice #LinuxGaming moment last night
I finally formatted one of my 1 TB SSDs as EXT4 to make room for #Steam games on my #ArchLinux install.
Then, I installed Transport Fever 2 and played it through my #SteamLink
And you know what? It just worked. It was a miracle! I just happily played for an hour without even noticing I'm not running #Windows. Zero tinkering. Thanks #Valve. ☺

edit: I like matrix.io more than discord. I will try to stick with matrix.io but yeah, discord has more people in it though :(...
