Solution to dual screen/monitor setup splitting TW on Linux

So I've wrestled with this problem some time and had problems finding working solution on the forums.

I saw these two, which both weren't useful to me:
https://www.teeworlds.com/forum/viewtopic.php?id=5169 <-- impractical and couldn't get to work on RadeonHD 7750 card
https://www.teeworlds.com/forum/viewtopic.php?id=2267 <-- Didn't offer any real solution as far as I understood.

So after fighting with this a while and managing to solve it.

I present you the solution.

1. Open up your terminal (gnome-terminal for most gnome based systems, konsole for KDE based)
2. Type in

export SDL_VIDEO_FULLSCREEN_HEAD=0

In-case it doesn't work, you may try change "0" to "1" or so, if it doesn't work with this, I'm out of ideas, sorry

Tested on Linux Mint 17.1 Rebecca but ought to work on most Linux distros
