I run a system with dual displays at 2560x1024. This works well except vendetta will not let me use any resolution other than 2560x1024 and 2048x768 and therefore, stretches across both screens and leaves the crosshair right on the edge of my two monitors which makes it very hard to play. Is there any way I can get it to use a "standard" resolution? I'd love to play it in a 1024x768 window or so...

I have the same exact problem.. albeit with 2048x768 resolution instead. It appears that vendetta is not xinerama aware, however it would make sense to allow changing the resolution, rather than just using the static one the X server gives it.

You can play it in a window. Options->Video->Window/Full Screen. Change to Window, then change your resolution to whatever (mine is set at 1024x768 at 84 Hz).

No, vendetta is not xinerama aware. It uses the Xxf86VidMode extension to determine the available resolutions, which will be the same ones you have listed in your X configuration. Probably the easiest way to fix it is to edit your ~/.vendetta/config.ini and set your xres and yres to 1024 and 768, or whatever, and set windowmode=1.

if i recall... xinerama disables GL Acceleration (unless that is only on the Matrox G400) anyway. that said, if you disabe Xinerama, it runs a seperate server on each head which *I* find to be atleast (if not more) useful then the streching...
