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.

commit 06618a9b3d9585508b0debd18d5b981636f98c54 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Mon Dec 3 13:25:19 2012 +0000 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.
