Dual screens on x220 & Ubuntu 12.04

[radek220]

I'm runing Ubuntu 12.04 on my X220. All happily working with external 23" DELL UltraSharp U2312HM using DisplayPort cable. There were some issues with setting dual screens in previous versions of Ubuntu but apparently 12.04 release fixed major problems (more info here).

I was thinking about getting another Dell display of the same configuration. Laptop has two graphical outputs DisplayPort and VGA. And Dell monitor I'm thinking about supports both of this connections.

My question: is it possible to use two screens without the UltraBase?

Thanks for help!

Yes, this should be no problem, but 2 concurrent displays will be your limit - you will have to switch off the Laptop's LCD (LVDS) when you run the two external monitors.

Whether you use a docking station or the built-in ports should make no difference.

Intel's new Ivy Bridge (in the X230) actually supports 3 simultaneous outputs, which is nice.

gdi2k, thanks a lot for reply. Having two large screens I think I can leave without laptop LCD.

Three on Ivy - that would be sweet!
