Working with Linux

I’m a Linux (Ubuntu) user and am new to Garry’s Mod. Before I purchase, can anyone tell me if it works with Ubuntu and what the requirements are. Also, is it a standalone game or do I have to use it in conjunction with anything else?

Me and my friend just got off linux, and I’m preety sure he was using Ubuntu, It’s fun for learning and such, but I my self wouldn’t choose it to host on over Windows.

GMod is standalone, although most mutliplayer servers expect you to have CS:S too.
It might run worse than it is on Windows.
Fonts on Linux are broken.
