I have a new Lenovo T420s with Nvidia 4200M + Intel HD 3000 graphics cards. When I attach the laptop and monitors to the docking station, nothing happens – the monitors are not recognized.
What I have tried that did not work:
- all variations of the Display settings in BIOS (Dedicated, Optimus, Integrated)
- installing proprietary drivers
- then, I installed nvidia settings and ran
sudo nvidia-xconfig
after which I had to remove/etc/X11/xorg-config
before x would work again.
- then, I installed nvidia settings and ran
- using a vga cord (ubuntu recognized monitor but did not send any video there)
- removing proprietary Nvidia drivers
- reinstalling Ubuntu
- using Unity 2D and xfce
I have googled quite a bit with little success. I have been told by IT to install windows 7 and use Ubuntu as a VM. What are my other options?

Remaining Issues to Resolve
There are still a couple of issues. I'm still working on it. Most likely, a proper xorg.conf will solve them.
Hope it helps.
