I am running a Gentoo system and after upgrading to x11 7.3 now when I issue startx, xwindows starts with a screen resolution of 1152x768 54.8hz. Before I upgraded the system would start with whatever I had in the display section of xorg.conf. Once the system is up I can use xrandr to switch to my preferred 1400x1050 @ 74.8hz. In xorg.conf I don't have 1152x768 set and I have tried commenting out HorizSync, VertRefresh, adding Option "NoDDC" "True", Option "UseEDID" "False", and HorizSync and source: edid (x would not start with option) without success. My question is how does xwindows pick this resolution, how can I force x to use the resolutions in the Display Subsection or startx with 1400x1050..
