Cheers for this!! this worked perfectly. I have a single tiny problem though. Everytime i open a window, whether if its an application or just a folder, it automatically pops to the other screen, which is the laptop. Is there any fix for that? SO that everything i execute opens within that monitor? Cheers by the way!

I have Ubuntu 11.04 and 2 Radeon 4350 video cards. Both the VGA and DVI (?) video ports work just great out of the box. I can’t get the other card (with the same plugs) to be recognized hence monitors 3 & 4 do not operate. The two cards work fine in Windows XP SP2 but only one card in Ubuntu. My ultimate plan is 3 monitors and 1 TV (the TV being run from the HDMI plug – small plug in port between the VGA and DVI ports). Any assistance on this problem would be greatly appreciated.

I had problems with dual monitors in 11.10, when I un-checked the mirror screens I would get this error message “required virtual size does not fit available size: …”
I tried numerous combinations of custom xorg.conf files and default vs. proprietary drivers (I have an ATI dual head card) nothing worked. Out of frustration I thought about reinstalling and older version of Ubuntu. That made me wonder if the problem was Unity or lightdm. I set my default display manager to gdm and the dual screen works!
The command is: sudo dpkg-reconfigure gdm
gdm may not be installed, to install it : sudo apt-get install gdm

cheers!

I just recently upgraded to Ubuntu 11.10 from 11.04 and have a little problem with the default settings for dual monitors. In 11.04, there was a setting in the display settings that would make the monitor positions default for logins but that seems to be missing in 11.10. My second monitor is on the right of the main monitor but at the login screen, the system thinks its on the left. After I login, the system thinks its on the right, I assume based on my user configuration. I need to set the default to that for logins. How do you do that in 11.10?

Please help. Drive crashed and am now learning Xubuntu with 11.04 loaded and attempting to also run dualview on my monitors. Reading the posts, I have no “monitors.xml” file whatsoever. Is there a big difference between Unbutu and Xubuntu? Is there a solution to this challenge? Have a Dell 4600 w/2 Dell-16 VGA-1 monitors. Thanks in advance.

“Go to your places – home folder (with nautilus and ->View->Show Hidden Files on) then into .config/ and open the file monitors.xml with gedit or another editor, and make a backup, in case you destroy something.

For example with log in name vvvv this is the file /home/vvvv/.config/monitors.xml

In that file there are several configurations, look for the dual monitor one and look for the monitor you want to be default – e.g. DVI-0.

There should be a line: primary=no which you change to: primary=yes”

Hi!

That was so easy / for linux /

But it worked perfectly. I now have the DVI monitor als primary, alhtough it was not described as DVI, but HDMI!

HI,
I have a 23″ syncmaster and sony bravia 40″ as dual monitors. By default it selects sony TV as the default, but I would like to make my LCD monitor as default. Cannot find a way to do this using ATI Catalyst Control option or anything on Ubuntu to change the default monitor. Any help will be appreciated.

Thanks,
Raj
