Description:
As per summary, I get low color depth (~16bpp) on my Macbook Pro 2012, with integrated Intel HD 4000 VGA device.

Xorg log file reports 24bpp, but it's clearly wrong as I can see infamous color banding
I tried searching for it, but I couldn't find much. Looks like it's related to EFI, someone suggested as a workaround to boot via grub-bios.
