I put several hours into adding a "How to setup a dual monitor" in Ubuntu's Wiki. I hope this will help other people. I know if I would have been able to read this that it would have saved me a lot of time. I hope this saves other people time.
Creating xorg.conf in Ubuntu 9.10 for monitor resolution
location: linuxquestions.com - date: March 9, 2010
thanks a lot for your great help in advance. I found quite a few similar threads for my problem, but though I think I basically know the way how to solve it, the exact solution is not clear to me.
Since the display of my notebook doesn't work very well anymore, straight vertical blue line on the right side of the screen, I want to connect an external monitor. (ADI [it doesn't say the exact model] 21 inch; resolution 1600x1200 and 85 Hz refresh rate).
I'm using Ubuntu 9.10 with kernel 18.104.22.168 and xrandr does not recognize the monitor correctly (see code of xrandr output). Adding a new mode did not work and currently it displays a resolution of 1200x768 which is horrible. In this version of Ubuntu the xorg.conf is not used anymore and is thus empty. As I have read you could create an entry in a new xorg.conf for your hardware which would be used by Ubuntu, having priority over xrandr settings.
But I do not really know what the monitor section in xo
unity dual monitor configuration

What do you guys think of the new dual monitor configuration in 12.04 where the unity launcher shows up on both monitors? I think this should at the very least be configurable to show up on one or both monitors.

Ubuntu 11.10 no separate dual monitor option
location: ubuntuforums.com - date: October 16, 2011
I have Win 7 and no problem using dual monitors i split-screen mode.
Ubuntu 11.10 loads fine and gives me a mirror image on the second monitor.
System Settings Hardware>Additional Drivers Shows ATI/AMD proprietary FGLRX graphics driver active.
Display shows a single monitor with the mirror display applied. Uncheck the mirror display and shows dual monitors BUT when I select apply receive this message "The selected configuration for displays could not be applied:required virtual size does not fit available size: requested=(2560, 1024), minimum=(320, 200), maximum=(1280, 1280)
What do I have to do to get the dual monitors separated?
Ubuntu/GNOME dual monitor setup: Preferring the primary monitor
location: linuxquestions.com - date: September 3, 2011
this is the first time I'm starting a thread here myself, because so far I couldn't find answers to my questions elsewhere. Actually, they're very specific and, it seems, unusual.
I'm using a dual-monitor setup with Ubuntu 10.10 ("maverick") and the standard GNOME desktop. All installed packages are up to date. I configured the two monitors side by side, so that they yield a very wide desktop.
One monitor is a 19"/1280x1024, which I consider the "primary" screen.
The other is a 20"/1600x1200 used for special work.
My graphics adapter is a RADEON 9200 PCI with VGA and DVI driven by the open-source RADEON driver supplied with Ubuntu (even though I don't think that matters for my concern).
However, I'd like to operate the system with only the primary monitor powered up, and switch the other on only when I need it. But when I boot the system with only the primary monitor turned on, X will detect only this one monitor, and the desktop wi
ATI Radeon Dual Monitor Setup on Ubuntu 8.10
location: linuxquestions.com - date: November 2, 2008
I've installed the latest fglrx envy driver for my Radeon 2400 graphics card and it works great. Only problem is I can't get dual monitors working. When ubuntu tries to detect the monitors it only sees one and both screens mirror the same thing.
How do I get both working?

Dual monitors. Ubuntu cant detect main monitor
location: linuxquestions.com - date: July 26, 2013
Hi, My PC has a VGA port only, no DVI or HDMI ports. I installed a nvidia 290NVS dual graphics PCI card to enable me to have two monitors, and used windows to update the drivers. Windows detected both monitors immediately, but Ubuntu detects only the secondary 19" HP monitor. The main 22" TV monitor opens the grub menu but as soon as it starts booting into Ubuntu it loses the signal, and the screen turns blue. At this point the 19" HP 2nd monitor kicks in and boots the ubuntu OS system.
The original graphics were Intel G41 chipset. The bios records only the nvidia card as does the ubuntu system although the drivers quoted are nouveau.
I have been advised that it is a driver issue but I find this difficult to understand for the following reasons.
The drivers, graphics and screen work perfectly on the 19" HP monitor so why would I need different drivers just to have an additional monitor???
If I disconnect the power cable from the 19" HP 2nd monito
ubuntu 11.10 Unknown monitor
location: linuxquestions.com - date: January 12, 2012
The other day I thought, "Hey. I want something new. Why not linux?" So I downloaded ubuntu 11.10 and installed. After installation I had to edit my grub file so boot would not leave me with a blank screen. It successfully worked.
But one MAJOR problem which is really irritating me is the display settings. Hopefully you guys and experts can guide me through the process of fixing this. Just for you to know: I'm not a big expert on drivers/hardware. All I know is that on windows (I dual Boot), my max screen res is 1366 x 768 pixels, which is 16:9.
My only two available options are:
1024 x 768 4:3
800 x 600 4:3
It also Says 'Monitor Unknown'
I tried finding out solutions to to fix this, and even threads that said, 'solved' I still didn't understand. That's why I am resorting to making my own thread, asking for guidance. Hopefully you can guide me through the process of fixing this problem.
External monitor displaying in nonnative resolution [Ubuntu 12.04]
location: linuxquestions.com - date: May 12, 2012
In attempting to hook up an external monitor to my netbook Ubuntu doesn't detect the monitor is plugged in (read: not showing up in Displays, not even as "unknown"), although on restart with it still connected (through VGA) display is cloned to the external monitor, albeit poorly.
The netbook's native resolution is 1024x600, but changes to 1024x768 when booted while connected to the external monitor (I assume that the external monitor is displaying in the 1024x768 also). The external monitor's native resolution is 1600x900, and displays with odd brown undertones, similar to that when F.lux or redshift are activated, although I have neither installed.
