I'm using Ubuntu 9.10 with an Intel graphics card (Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)) and a dual monitor setup in Gnome. I run Compiz as a window manager.
When I tried to close the game, my primary monitor was automatically turned off and everything switched over to my secondary monitor. I attempted to close the game several times, but it was locked up hard. I resorted to using the "xkill" command.
Here is a log of the game.
Whenever I open the game (even just to the lobby screen) and close it, there is the mode reset.

Note that the "Desktop Display Mode: 1024 x 768 x 24 @75Hz" line is incorrect. That is the mode of my secondary monitor. My primary monitor is 1280 x 800 x 24 @60Hz.
I'm not sure why Planet M.U.L.E. feels the need to screw with my resolution settings at all; it didn't touch them to start with.
From what I understand, X.org handles multiple monitors by allocating a desktop space larger than all attached monitors, then placing the monitors on top of this space, like views into a larger room. Because there is a 14 pixel difference between the heights of my monitors, there is a 14 pixel gap either above or below the 1024 x 768 monitor in which windows can be dragged. Hope that helps.
