Have you tried using each monitor separately? It's my experience that XOrg doesn't always detect OR present the full range of resolutions. A typical one being missing from the list is the quite common 1366x768 resolution of (democratically priced ^^) small screens. The solution is to define the resolution you want via xrandr and then add it to the monitor where it's missing: For instance, to ensure I can run a distro on an external drive in VIrtualBox without messing up my desktop layout: > xrandr --verbose --newmode "1366x768" 85.25 1366 1440 1576 1784 768 771 781 > 798 -hsync +vsync > xrandr --verbose --addmode Virtual1 "1366x768" Note that this apparently works at the screen level, but I presume the resolutions you mentioned were just that, not the union of resolutions of both screens. I also don't know how to obtain the various numbers other than by querying xrandr on a system that does recognise the resolution you're looking for. R.
