Both outputs are probably ending up on the same crtc by default (use xrandr --verbose to verify). So you probably want something like: xrandr --output DVI-0 --crtc 1 --mode 1280x1024 --right-of VGA-0 This page has a lot of good information about configuration using xrandr: http://wiki.debian.org/XStrikeForce/HowToRandR12 Alex _______________________________________________ xorg mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/xorg
