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...

Adding New Wine Directories and Architectures

By default, Wine creates its directory in your home directory with the folder name ".wine" matching the architecture of your operating system (whether it's 32bit or 64bit).

Sometimes a program doesn't run or run correctly when your Wine architecture is set to 64bit. Rather than erasing your entire Wine directory (and every Windows program you've installed) you can create a new directory with a 32bit  architecture and run Wine out of it being its default location.

Unity Launcher and Menu Bar Missing

While it appears to be an issue that has plagued a hand-full of Ubuntu users, for at least 6 years, it still seems difficult to find a fix.
On installing Nvidia drivers in Ubuntu, after logging in, the entire Unity and menu bar are nowhere to be seen.

Rather than being presented with the usual desktop interface.

The user has displayed for them the lovely purple Ubuntu background instead (in whatever incarnation that version is using).

Luckily there's a fix...
