Lenovo x220 Docking station display setting issue
I'm currently running 12.04 LTS on my Lenovo x220 i7. Its works really well, however there seems to be a problem with the screen resolution when on the dock.
At first I was using the laptop with an external screen connected via the VGA port on the side of the laptop. I have it set up as a mirror with the laptop screen shut down. And the aspect ratio / resolutions was 16.9 and had a great picture.
I then decided to get a dock which has a VGA port on it as well as 2 x DVI connectors that can run 2 screens via the dock.
This is the dock.
I have the dock (Lenovo serious 3) connected to my screen via the VGA cable. My external screen is a 19” acer 16:9 resolution. However what ever settings I have in the Ubuntu settings. The laptop switched to a 4:3 and then stretches the image to fit 16:9. This is no good!
In my mind everything is pointing to the graphics driver. I think Ubuntu has all of this built in, but should I be doing manual updates too? The details of the system tell me the graphics are as follows Intel® Sandy Bridge Mobile.
