Mutual GNU / Linux

Hi. I'm a new player, but I can't use the game. I need some help.

I have linux with dual screen, and I want to use Ryzom windowed. Character selection screens runs smooth, but when I'm in the game... Well...
 
So, the left side is my desktop, my left screen. The right side is displaying Ryzom full screen... but wrong. See, is like Ryzom was using the whole resolution of my both screens combined, but starting at the second one, so half of the game is out of screen. I need some way to make this game start as a window instead of full screen.

Some help? Thank you!:

Option to use windowed mode is in login screen

Sorry... I use Linux, but with a 1 big screen :)
