- Lenovo T520 with integrated Intel HD graphics + a NVidia card (Optimus)
- Ubuntu 11.10 on the computer.
- I would like to use the built-in screen plus two external screens.
- This PDF indicates that it is possible to connect up to four external monitors to the laptop. The information is Windows only.
- I was planning to disable the NVidia card, since I have read that Linux support for Optimus is not good.
Questions:
- Has anyone set up three monitors on NVidia hardware?
- Has anyone set up three monitors using Intel HD 3000?
- Can I expect it to work out of the box, or are there tricks I need to be aware of?

With Optimus enabled and OS detection on in the BIOS, I've got 2 external DVI connected monitors (docking - Nvidia card) and the laptop LCD (Intel card) to work. I did also get the VGA (Intel card) on the docking working, but was not able to not have it as a clone of the laptop LCD.
Here is my xorg config with Xinerama enabled:
In the "DeviceIntel" section is my last attempt to get more than one monitor on the Intel card.
Here is an extract of my "lspci":
