--- Comment #18 from Chris Wilson <chris at chris-wilson.co.uk> ---
Oh. Forgot one important detail, iirc that is, in order to get the third output
working (without eDP), at least 2 of the outputs must share the same clocks -
they have to share a PLL.

Try:
xrandr --output LVDS1 --off --output DP1 --off --output DP2 --off
xrandr --output DP1 --mode 1920x1080 --primary --output LVDS1 --preferred
--right-of DP1 --output DP2 --mode 1920x1080 --right-of LVDS1

Can you look at what configuration you get with Windows? If they are able to
driver all 3 at their preferred resolution, they know more tricks than we do...
