I can confirm this bug -- Looks like we have the same laptop and have the exact same symptoms, Plain vanilla does not indeed work: on boot, screen changes mode 3 times before settling on 1920x1080 -- then gives "low graphics mode" dialog on lightdm startup. Must boot with nomodeset and set mode manually for this chip. Still can't get the color depth correct either. Using xorg-edgers and oibaf ppa drivers.
