Doesn't matter what distro. You need to do some tricks for intel opengl work 100%.
And NOR ALL cards/computers have the lucky of own a bios with the option for default video output or that is coded with AMD being the primary.
Example, AMD 6850 card. I still didn't know ANY notebook with catalyst working. Look around just a minority cards/manufacturer work with this "STRANGE CATALYST BEHAVIOUR"
Seems is more like a weird behaviour from catalyst than something "purposeful".
