I am proud to be a Wasteland 2 backer. Today I wanted to run it on Ubuntu, but I couldn’t. However, after an hour of googling, everything worked out. It turns out that Unity has serious problems with Linux, but by using certain hacks, the game can be launched:
ulimit -Sn 65536~/.local/share/Steam/steamapps/common/Wasteland\ 2\ Director\'s\ Cut/Linux/WL2
