Could be wrong as it's going off second hand info, but I've heard from a workmate that runs Ubuntu that when he tried to load up a fresh install of 11.10 (or maybe 12.04?) on his optimus laptop, that it came up with a black screen after install. I assume this may have been due to the nouveau driver build of that distro attempting to initialise? I wouldn't call that exactly working out of the box... Apparently running an older version of Ubuntu managed to get him a standard display though.
No announcement yet.
