I'm a total newbie with Ubuntu, installed Windows and built PCs numerous times over the years, but this O/S is utterly new to me.

I am trying to install Ubuntu 11.10 64-bit with a Nvidia/Asus GT520 graphics card. I can get as far as 11.10 & the Proprietary drivers installed but I can only see the flatscreen on the DVI cable, the Plasma screen on the VGA cable remains off. In the System Tools folder the icon about Displays is only showing the Dell screen as connected, if I click 'detect displays' the VGA is not detected. If I swap the hard drive with one containing Win XP O/S the screens are fine, so I assume the hardware is OK. Ultimately what I want is to use the extended desktop/workspace across the 2 screens as I can do in XP. Could someone help correct this problem. Please do it step by step, this is a new O/S to me and it's a bit bewildering.

  • 64-bit ready

Try running gksu nvidia-settings in a terminal and set your resolution from there. – bodhi.zazen Feb 28 '12 at 19:48

Unfortunately, you won't be able to set dual monitors with the default monitors tools.

Open up the dash and start typing Nvidia. You should see an application called Nvidia-Settings. Use this to set your monitor configuration.

Good luck!
