fglrx 7.12 resolution problem

[William Murray]

  Hi all,
        My laptop has a 1400x1050 screen, always been fine. The latest
fglrx only seems to give me up to 1280x1024. 
Looking in Xorg.0.log shows:
   (II) fglrx(0): Supported VESA Video Modes:
(II) fglrx(0): 640x480 at 60Hz
(II) fglrx(0): 800x600 at 60Hz
(II) fglrx(0): 1024x768 at 60Hz
(II) fglrx(0): Manufacturer's mask: 0

(II) fglrx(0): Supported additional Video Mode:
(II) fglrx(0): clock: 108.0 MHz   Image Size:  0 x 0 mm
(II) fglrx(0): h_active: 1400  h_sync: 1448  h_sync_end 1560 h_blank_end
1688 h_border: 0
(II) fglrx(0): v_active: 1050  v_sync: 1051  v_sync_end 1055 v_blanking:
1066 v_border: 0

  Does anyone know what an additional Video Mode is, and how to write an
xorg.conf which will use it?
        Thank you,
               Bill
