Run Warsow and getting black screen with message...

"Display is not supported" or "Out of Range". This only happen to lcd monitor.
Solution:
1) Edit Warsow config file

    $ gedit ~/.warsow/basewsw/config.cfg

2) Search for "vid_customheight" and "vid_customwidth" and change the value to one of the resolution (higher than 800x600) that works with your monitor

    seta vid_customheight "768"
    seta vid_customwidth "1024"

Same problem happen to me with Extreme Tux Racer.
Solution:
1) Edit Extreme Tux Racer options file

    $ gedit ~/.etracer/options

2) Search for "y_resolution" and "x_resolution" and change the value to one of the resolution (higher than 800x600) that works with your monitor

    set x_resolution 1280
    set y_resolution 1024
