Have you tried using bumblebee[1]? I use it on my Samsung QX411 which has an NVidia GeForce GT 525M video card along with the onboard Intel. The Intel card is used by default at all times. If you want to run a program using the NVidia card, just prepend 'optirun' to the command.

I tried bumblebee it on 12.10, after unsuccessfully trying to install Nvidia drivers. It was...not a good experience. Ended up reinstalling 12.10 just to get Unity and a reasonable resolution back. I have no doubt that there was a fix (possibly involving xorg.conf editing) but I had already spent so much time it and I needed to get work done. Hopefully the new release is better here, but I don't hold much hope.

I'm not blaming bumblebee specifically here, it's just a pervasive side effect of Linux and the modular approach. I can really appreciate the integration that goes in to a Mac.

I'm sure experiences vary greatly depending on the mix of hardware. I remember having to tweak some things to get bumblebee to work properly (or maybe I had to recompile from the source) but it's worked flawlessly since. This is on Ubuntu 12.04.

pkolaczk does bring up a good issue about the DisplayPort not working properly though. I don't use an external display on my laptop and have never played with that.

On another note, I remember installing 12.10 on my desktop right around the time it came out. My desktop has a Radeon HD3870 video card which was completely incompatible with Unity. I don't remember the issue exactly but my choice was either to use the open source drivers or have the desktop environment fail to show at all with ATI's drivers. I just did a search and I guess the fix is to downgrade X-Server and install a legacy driver. It's a shame something as central to the user experience as GUI performance still doesn't work out of the box or worse yet, critically breaks on an upgrade.

For me bumblebee works, but then the DisplayPort is useless. It would be awesome if bumblebee could automatically detect that the laptop is docked and turned on the external graphics to enable proper functioning of DisplayPort. Or even not automatically, but simpler than uninstalling/installing bumblebee (and fixing the mess it did to config files everytime).
