New laptop with 12.04 not connecting to external monitor

Asked by Lucy Dixon on 2012-07-06

I have installed Ubuntu 12.04 on my boyfriend's new Dell XPS15z laptop. With his old laptop (& windows) he used an external monitor - an Acer X203h.

We've tried connecting it to the new laptop now that it has Ubuntu, but they're just not talking to each other! An Ubuntu icon briefly flashed up on the screen when we switched off the laptop, but nothing since then. Under System Settings/Displays only the laptop screen is showing up...

Are there particular drives I need to install? I've been reading up on it, and the word Nvidia keeps popping up, but I'm rather in the dark here.

I've tried using Fn F1 and modifying all the options...

One more thing: the laptop only has HDMI ports, and the monitor only has VGA ports, so we have an HDMI to VGA adaptor connecting them...

My laptop has Ubuntu 11.10 on it, and is working perfectly with the monitor and adaptor cables.

Dual GPU is a massive headache in Linux and is best avoided. This may help

The Dell XPS 15z laptop has a hdmi and a mini displayport connector. The HDMI doesnt work. For mini-DP, you better buy an apple connector mini-DP to VGA ( since that one surely works, a lot of cheap adapters are passive and will not work anyways ). has more information about all parts of the laptop.

Can you help with this problem?
