It's a laptop, 15" macbookpro (MacBookPro6,2) http://www.everymac.com/systems/apple/macbook_pro/specs/macbook-pro-core-i5-2.53-aluminum-15-mid-2010-unibody-specs.html And yes, turns out apple have gpu switching: http://www.techworld.com/review/laptops/apple-macbook-pro-15-inch-mid-2010-266ghz-core-i7-review-3223803/ I ran FreeBSD for a test; it gets stuck too. Xorg with linux behaves fine though. Xorg log shows two drivers are loaded, nouveau and intel. Until DragonFly's grahpics stack gets this feature, I wonder if there's a way to switch off one gpu so Xorg will run? Cheers Peeter --
