** Description changed: Over a year after its release, there is still no Optimus support in Linux, either in nvidia-current or in the nouveau driver. Unless there is a BIOS setting that allows you to turn off the Intel iGPU, the only workaround is to use the Intel iGPU and, if possible, save power by turning off the nvidia card via an ACPI call. It appears that in most cases, to cut costs, the manufacturers don't supply the hardware MUX that allows you to select nvidia graphics, so there is no such BIOS option. http://ubuntuforums.org/showthread.php?t=1657660 has a summary of the issue. Apart from being a great annoyance to people who buy a laptop with an nvidia card and discovering it just doesn't work in Linux, this is a big problem because other basic functions like running an external monitor via HDMI will most likely not work (eg see https://lists.launchpad.net /hybrid-graphics-linux/msg00701.html - HDMI is attached via the non- working nvidia card). I don't mind so much about only being able to use the Intel graphics (even despite the driver being less stable than nvidia-current), but not being able to connect an external monitor is a show-stopper for me. Last year it was possible to get a laptop with an i7-series CPU and a working nvidia card, because it the i7 CPU last year didn't have an iGPU. But Sandy Bridge CPUs all come with internal graphics and are now the norm (and if you are buying a performance laptop, why wouldn't you want a SB CPU?), so it is almost impossible now to buy a performance laptop with a working nvidia card (ie working HDMI). Will this slow the future uptake of Ubuntu? I would suspect that it must do at least for users who have performance laptops, since Ubuntu now can't drive external monitors on a reasonably large portion of new laptops. Will people stop using Ubuntu on performance laptops because of this? By the same logic, there must be current Ubuntu users who will be forced to use Windoze just so they can get external monitors working. (Sadly, it looks like I might fall into this category when my company upgrades its laptops soon.) nvidia has stated that they have no plans to support optimus on Linux, but that one day they might have to. Is there a way to give them an incentive to do so, other than by moaning on the nvidia forums (eg http://www.nvnews.net/vbulletin/showthread.php?t=144750).
