Hi rob,

I tried the xrandr , it worked.  Lvds being primary, HDMI extended.

In kernel, DMA_p and DMA_e is having the same frame buffer, the final
display suppose to be mirror display, but how the display is extended with
independent resolutions 1080p and 1366x768

For mirror display both resolution should be same, since lvds resolution is
not a standard wrt TV/HDMI resolution, this cannot be achieved until
1366x768 fb is scaled to 1080p of TV as they do in android.
Is this achievable wrt DRM architecture?

regards,
vinay simha bn
