The problem you seem to be having is from incorrect drivers. Finding the correct driver for your hardware can be a bit difficult some times.

For this I would recommend a Google search for "driver doctor". The first link should take you to the page that tells you about the program. This program scans your hardware and provides drivers from the manufactures site for the specific hardware you have installed.

The downside to this is that you have to pay (I am not sure how much, but I think it is somewhere around $20 - $40).

When using a PCI or PCI-E graphics card, it will disable your standard VGA output port because the up-dated graphics card and your factory VGA port require different display drivers. Usually, the drivers are conflicting and will make your system unstable and cause it to crash. In short, you can't use both at the same time. I have a Radeon HD 5450 graphics card installed on my PC and it too has disabled my standard VGA port. If you are trying to use more than one monitor, you have to install a graphics card that supports a multiple display output. The graphics card will either have 2 VGA ports, 2 DVI-D ports or 2 HDMI ports or even any combination of the 3. My card, for example, has 1 VGA, 1 DVI-D & 1 HDMI. I can run up to 3 monitors at a time via my graphics card, but I cannot run a 4th monitor from my factory VGA port. My graphics card uses ATI/AMD drivers while my VGA port requires the use of Nvidia drivers. I hope that you find this useful.

Then you have to go back to the distributors of this Linux distribution and list the drivers for the items you need. Linux drivers are open source programs, so the drivers from one computer can be complied into another distribution, if they use the same chips. The manufacturers such as Lenovo rely on third parties to provide any software that they do not support, they do not have to write them.
