Why?

While I was trying to setup my cosmic session I wanted to use Cosmic Greeter as my Display manager because I wanted to test it out and give my own feedback/report any bugs I could find.

However I didn't find any guide on how to do it plus there's little to no clue on how to set it up and it took me 2 days to figure it out.

That's why I write this quick guide.

How does Cosmic Greeter work? (ig)

Cosmic greeter by itself doesn't work it needs a Compositor (in this case Cosmic-Comp (obviously)) to actually run.

Steam Download Speed is so slow on Linux

Oh boi, here I give you the solution for that. This document is based on these links:

• https://steamcommunity.com/app/221410/discussions/2/616189106498372437/?l=portuguese&ctp=8
• https://wiki.archlinux.org/title/dnsmasq#NetworkManager
• ValveSoftware/steam-for-linux#3401

TLDR

My solution seems to be deprecated, there are other solution from the comment on this Gist, that actually works. So, please use that instead, it's way much simpler, and it works.

XDG - Base Directory Specification

Directories

Base

The intended use-case for BaseDirectories is to query the paths of user-invisible standard directories that have been defined according to the conventions of the operating system the library is running on.
