Help with Lenovo W520 Dual Monitor

Postby haidong on Mon Mar 25, 2013 4:43 pm

Lenovo W520
Linux Mint 14 Cinnomon 64-bit (MATE 14 64-bit has the same problem but I like Cinnomon better)

Problem I have:
I can use either the built in laptop monitor or external, but so far not both at the same time. I use a DisplayPort to HDMI converter to connect to the external monitor. This is a vanilla Mint install with no nvidia driver.

Results of lspci | grep VGA
