Remember that we are talking laptops, which typically means hybrid nvidia-intel graphics, and these are a pain.
On a laptop, I have had better luck with Nvidia. AMD will just draw a line in the sand and stop producing drivers for all video cards before model X (recall the fglrx debacle on 10/2008?) The only issue with Nvidia cards is whether you use the nouveau or proprietary drivers. Both use different /sys/class/backlight interfaces so you can lose backlight (screen brightness) control. (it's still there -- what you have to do to make it work changes) Pure Intel graphics are also well supported out of the box. With 42.2, I ran the Nvidia propriety drivers, for 42.3 I haven't bothered with the install. Nouveau performance is fine for my purposes. If I load compiz, then I switch, but I don't game, so FPS isn't really an issue. Video and 2D graphics is fine with either. No problems either way. (except hacking how /sys/class/backlight/acpi_video0/brightness gets set, or change to xrandr control) -- David C. Rankin, J.D.,P.E.
