That might be actually your issue here. If you at one point created a xorg.conf (check "man xorg.conf" for all possible locations) it might get in your way. By default a modesetting server is started which collects the monitor's EDID information and sets the modeline automagically. Would you try moving any existing xorg.conf out of the way and starting xorg without? -H -- Henning Follmann | hfollm...@itcfollmann.com
