Dual monitor setup on Linux Mint

I had a dual monitor setup running perfectly on Linux Mint 10, but struggled to get it going under Mint 11. From Googling it appears I was not alone, so I decided to skip 11 and revert to 10.

These are the steps for a clean Mint 10 installation:

1. open the additional drivers application and install the recommended drivers and restart the machine
2. open the NVIDIA settings and enable the second monitor and check the Xinemara box
3. restart the machine

That's it!
