view story

http://ubuntuforums.org – Platform: ----- Mint 13 KDE Intel G620 GTX 460 1GB Dell 1280x1024 (x2) Monitors ----- So i've installed these linux games (all Linux native) 1. Trine 2 2. Savage 2 3. Xonotic previous (not the 2012 version) 4. Anomaly - Warzone Earth Only Trine 2 is naturally (default) capable of running on one monitor the other 3 requires me to disable monitor 2 for it not to expand to 2560x1024 resolution does anyone know how to set games to run on one monitor only -- may be in nVidia Settings ??? there's no setting on these games to force resolution to 1280x1024 only (Hardware)
