--- Comment #18 from Chris Wilson <chris at chris-wilson.co.uk> ---
The downside is that we might end up with two nearly identical modes listed in
xrandr, but it will stop xrandr from bugging out with an error:

    sna: Append the current mode to the output list if not found

    If for some reason the current mode on the CRTC (inherited most likely
    from fastboot) doesn't match any of the modes reported by the output, we
    end up with a stray mode that the client cannot control.

As to why we end up with two almost identical modes - we can leave that for the
masochists...
