Linux, dual monitor (two screens)

Hello

I work with two monitors under Linux KDE. I usually work in full screen with programs like Chrome, Firefox, Steam games, etc. They work only in my "favourite" marked screen, so no problems. However, Zero-K (and NOTA for example) extend screen between my two monitors, so it's difficult to play. Battle Annihilation or EvolutionRTS games run fine, fullscreen or even like windowed, but without windows decorations.

I just tried all posible screen and dual screen related options in "springsettings.cfg", but no luck.

What's going bad with Zero-K?

Thank you

Not working. In fact, I just tried same config before (I found that config somewhere in forums). Zero-K put my 1920 width fullscreen game between my two monitors, adding black bands at right and left. Balanced Annihilation howerver, stays showing correctly only in my "default" monitor (the larger one).
I must mention that there is something more in this mistery. While Zero-K capture my screen completely, that's to say, I have no access to my auto-hidden menu bar ("panels", in KDE) I have total access to my auto-hidden panels of KDE while playing at fullscreen in BA or EvolutionRTS (my panel appears when my mouse pointer is near the border where the panel is hidden), and even I can move my mouse pointer to my other screen. Is like BA (and other spring games) were in a "semi-fullscreen" mode or similar.

No. I only use Spring Web Lobby for all the games (ZK, BA, E-RTS, etc). So is something in ZK, not the lobby.

So, do you think is a SpringWebLobby related issue?
