Description Gašper Sedej 2012-10-03 06:34:55 UTC 
Hi

Please add 1024x768 and 800x600 modes as availible modes for LVDS on gma500_gfx.

I have Asus eee 1101HA with monitor 1366x768, which I use for presentations. In "xrandr", I just see mode 1366x768 (which projector does not support), but no 1024x768, which is ok for most devices. I have to add manually "xrandr --addmode LVDS-0 1024x768" to be able to have normal clone screen on both displays.

    Add missing GTF modes
    
    A fixed-mode output device like a panel will often only inform of its
    preferred mode through its EDID. However, the driver will adjust user
    specified modes for display through use of a panel-fitter allowing
    greater flexibility in upscaling. This is often used by games to set a
    low resolution for performance and use the panel fitter to fill the
    screen.
    
    v2: Use the presence of the 'scaling mode' connector property as an
    indication that a panel fitter is attached to that pipe.
