Is it impossible to get a 700x525 resolution?
xrandr -s is xrandr 1.0 API. It has no concept of multiple outputs. Since the radeon driver is xrandr 1.2 compliant, it's a better idea to use the 1.2 API: xrandr --output LVDS --mode 700x525 Alex _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
