I'm unable to start a game, because the main menu is missing from my start screen. :( Help?

I found a workaround at the developer's forum.

In my case, it appears to be a problem with handling of dual monitors. I found the Configuration.txt file at my Home directory in My Games/Lords of Xulima/, but it showed a graphic width of 3600 pixels. I changed it to 1920 pixels to match my main monitor, and now the main screen loads normally.

Problematic, though, is that I simultaneously lose all display on my second monitor. :( And after I exit the game, I have to go to system preferences to activate my monitor again. So I'll consider this change merely a workaround to play the game instead of a proper fix.

There's a problem at the developer's forum, so I'm unable to register a new account to let them know of my findings. I've emailed them the error code, so hopefully they'll fix the website soon.

Why not write a shell script that does the following:
1. Sets the screen resolution to something that works for playing the game.
2. Starts the game in the foreground.
3. Restores the old screen resolution.

(Hint: Use xrandr to change the resolution.)
