thanks Smirftsch, for doing the port.
I got a dual monitor setup with the proprietary nvidia module, but when I start unreal it won't let me change my resolution to a smaller size (or larger...) instead Unreal spans both monitors.
is there a way that I can edit UnrealLinux.ini to force a certain resolution?
I am using compiz on the gnome desktop.
I might be able to get compiz to load the Unreal window at a certain x y position but first I would like to fix the Unreal resolution.
thanks.

no idea at the moment. When thinking about it I even tend to say that maybe NVidia messed it. But then again I don't know crap about dual monitor usage (programming wise) and if there is maybe a specific parameter or command to be set, so I need to look into it first.
