    Default 13.1/64 and ASuS X5DC (Sis 671/771 PCiE) laptop having only 640x480 (Native is 1366x768 in Win)

    Have some trouble getting proper resolutions out of this, it's reallt a 1366x768 display panel.

    Code:
    -:~> xrandr 
    
    xrandr: Failed to get size of gamma for output default
    Screen 0: minimum 640 x 480, current 640 x 480, maximum 640 x 480
    default connected 640x480+0+0 0mm x 0mm
       640x480        73.0*

    Default AW: 13.1/64 and ASuS X5DC (Sis 671/771 PCiE) laptop having only 640x480 (Native is 1366x768 in Win)

    I says:
    Code:
    (EE) SIS(0): No valid modes found - check VertRefresh/HorizSync
    So try to remove/rename /etc/X11/xorg.conf or change it.
    The VertRefresh value seems to be set wrong.

    The log also mentions:
    Code:
    (II) SIS(0): Monitor1: Using vrefresh range of 59.00-61.00 Hz
    (II) SIS(0): Monitor1: Using vrefresh value of 71.00 Hz
    
    This would of course explain why there are no valid modes found. 71Hz is outside the monitor's apparently accepted range of 59-61Hz
