I have installed the Linux version of the Game just fine, but when I try to start either of the three desktop options (Flatout, Flatout (Windowed), Flatout (Settings)), absolutely nothing happens. No error message or anything. I then tried to start the start.sh via console:

kazuya@ZOD:~/GOG Games/FlatOut$ ./start.sh

It just stays there forever. I have waited several minutes and nothing happened.
I then found a hidden logfile (seriously, who decided it is a good idea to keep logfiles hidden?) .tmp_x11.log in ~/GOG Games/Flatout/drunk

Here is the content:

So, I had a look at drunk.sh, but I'm not sure what I should do, to fix the problem
