I'm not real sure how xrandr works, but if I run xrandr at a prompt I get this: SZ: Pixels Physical Refresh *0 1280 x 800 ( 433mm x 271mm ) *60 1 1024 x 768 ( 433mm x 271mm ) 60 2 800 x 600 ( 433mm x 271mm ) 60 3 640 x 480 ( 433mm x 271mm ) 60 4 640 x 350 ( 433mm x 271mm ) 60 5 640 x 400 ( 433mm x 271mm ) 60 6 720 x 400 ( 433mm x 271mm ) 60 7 832 x 624 ( 433mm x 271mm ) 60 8 1152 x 768 ( 433mm x 271mm ) 60 9 848 x 480 ( 433mm x 271mm ) 60 10 1280 x 720 ( 433mm x 271mm ) 60 11 1280 x 768 ( 433mm x 271mm ) 60 Current rotation - normal Current reflection - none Rotations possible - normal Reflections possible - none Where is it even coming up with these resolutions since I only have 2 specified in my conf file? You'll also notice that the resolution I want, 1280x1024, is not even listed. >From a hardware standpoint, the internal controller, or the one that drives the internal display probably does not support 1280x1024, but the external controller does. For example, if I boot into Windows XP I have different resolution options depending on which display I'm trying to use. Can you give me more specific details on how you're using xrandr? Thanks, James
