Configuring two displays with Unity

  • 772

I am currently running Ubuntu 11.04 beta 2 with unity on a laptop Dell XPS M1330. My Dell M1330 has an Intel chipset and this is the result I get for running the lspci -nn | grep VGA command:

00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) [8086:2a02] (rev 0c)

I have a 22" display at home, so I like to configure my laptop to have dual displays (with the Monitor preference GUI tool). The way I use it is with an extended screen where each display (my laptop and my other 22" LCD each works with their native resolution). Everything works quite well except for a little annoyance which I was hoping someone can help me figure out. Even though my LCD is configured to be on the left and my laptop on the right (that is how the two are set up on my desk), the launcher and top-right Ubuntu icon that brings up the Dash always appears on my laptop screen, when I would like it to appear on my left screen. I attached a picture to visualize this better.

Any help would be greatly appreciated.enter image description here

BTW, I checked out this question, and it doesn't really cover what I'm asking here.

Thanks.

    I had a similar problem, and someone directed me to the command xrandr.

    Apparently the Unity Launcher appears on the screen set as "primary", and this can be changed with xrandr.

    First run xrandr to get a list of outputs. For example, on my setup I get a bunch of things called DFP1, DFP2, CRT1 etc. After you have identified which of these is your external monitor, run

    xrandr --output XYZN --primary

    where XYZN is the output name (I have to run this for one called DFP5 sometimes). The launcher should immediately move to the output you chose.
