Hi Robert,

not be able to mirror and wrong resolution sounds like a bad video driver. Xfce does nothing itself here, but only parses what RandR provides. Test with »xrandr« why your video card doesn't support mirroring and look into /var/log/Xorg.0.log which driver is loaded. Install the appropriate if not already there.
