Garry's Mod Crashing on Launch (Fix)

Garry's Mod on Linux has always been a hot mess with plenty of random crashes for me. Crashing in game, crashing attempting to join a game, crashing when downloading assets, in addition to media not loading in Cinema rooms. Those are the problems with the game alone and not mentioning the terrible servers loaded with mods and over 5 gigabytes of downloads not for any good reason, but that's a different complaint.

It's now 2023 and I seem to have fixed my Garry's Mod to the point where it hasn't crashed once for me, so far. (Although some servers have been absolutely awful to play on, getting 2fps, thought these are the servers with 5+ gigabytes of downloads. Servers that label themselves as "small download" yet still have 1 gigabyte or more, beyond frustrating, maybe it was better when I couldn't play it...)

Anyway, the fix. I did 4 different steps, without testing in between, so I'm not actually sure which ones are necessary, but if you want to figure that out you can.

Saints Row 3 Crashing in Multiplayer (Fix)

Saints Row The Third received a SteamOS / Linux release (along with Saints Row 2). My brother and I scored big on a deal from Humble Bundle Store for the Ultimate Franchise Pack (which also includes DLC plus Saints Row IV and Gat Out of Hell, both which have SteamOS / Linux versions).

I run Linux, my brother runs Windows, and it appears we're not the only ones who couldn't play Saints Row The Third in Co-op across two different systems... until...

The first few of hours I clocked up in SR3 were all in the main menu, we tried repeatedly to connect through all means, attempting to create virtual LANs amongst other things.
I noticed while connecting in online mode we could actually join each others lobby screens for a split second, he would hear a little bit of my voice through the in-game voice chat, then I would crash. The solution...

Custom Spray in L4D2

A common problem problem in Left 4 Dead 2 in Steam on Linux seems to be when attempting to import sprays, resulting in the error:

Spray Import Error
Unable to write output spray file. It's possible the current user doesn't have permission.

Whether this happens in other source games also, I do not know, however the fix should be the same.

L4D2 seems to perform half of the action needed, it just has problems when copying the actual image file into the folder it needs to be in.

So here is the remedy:
