I just installed Pixel Qi screen (PQ101WX01) on my Acer Aspire One D270, but I can only control dimming of the screen through OS. Dimming doesn't make it more readable in the sunlight, and going to sleep turns the screen completely black.
How do I shut down backlight and switch Pixel Qi screen mode of operation to readable in the sun?
I have access to both Windows 7 and Ubuntu (13 or more newer).
