I have a W520 with ubuntu 12.04 32-bit installed. I also have an additional monitor that supports DisplayPort. I have the laptop connected to this external monitor, however, I cannot get ubuntu to detect the display when using DisplayPort. I also tried VGA, and this is detected right away and the extra monitor functions well, but the picture isn't as sharp as it could be. So I would like to use the DisplayPort connector.
1. I have configured the graphics in the BIOS to always use discreet graphics.
2. I have the nvidia-current-updates-dev drivers installed.
Any ideas why the display can't be detected?
