Ubuntu Multimedia :: Turning Off Dual Monitors?
Jul 6, 2010
I want my video card to stop processing an image to my integrated monitor and only process images to my external monitor.
My problem is that I use my Toshiba Satellite M65 (which is a laptop) as a desktop: I use an external monitor, external keyboard, and of course an external mouse. I only recently started using Ubuntu after many years of Windows XP and I just realized that both my laptop's integrated monitor and my external monitor are 'on', displaying the same image. I want my video card to stop processing an image to my integrated monitor.

I just built a system with an Nvidia GT240 and Ubuntu 10.10. I have two monitors and am trying to get them set up. I currently have them working fine in twin view but I'd like to have set up as separate X screens. However, whenever I do that X crashes. I've got the latest drivers set up from the x-sane PPA so I'm not sure what more I can do. My driver version is 270.29.

I am using Ubuntu 11.04 - the Natty Narwhal 64-bit and I am using the Nvidia Xserver version 173.14.30 and it never has any problems when I am in single monitor mode but when I turn on twinview mode like this----
and click apply the new monitor first shows up black and when I move my mouse over the monitor stuff starts showing up and I am able to click ok to keep my settings
when I click ok the screens freeze. everything else works; I can move the mouse around and if I am playing music it still plays but if I click on any button nothing happens and nothing happens when I use the keyboard either. I would really like to be able to use both my monitors

Just installed a clean version of 10.04 onto my Sony VAIO with an ATI Radeon Mobility x700 video card.Whilst using 9.10 KK I was getting low resolution but the dual monitors worked totally fine.Which I use to connect to my TV via a RGB/PC Cord.Since upgrading to 10.04 the resolution is awesome BUT when I merge both monitors the laptop goes mental and shows a white/whitish screen.If I use have both monitors side by side its OK but then I cant run xbmc to show movies. I'm stuck with making the TV my main monitor, which is a pain.Why is the laptop going white after merging screens? Does anybody have any ideas?

Anyone want to take the time to help me get my ATI x16XX to work with dual monitors?I'm really tired and frustrated after upgrading to lucid and having the "vendor" drivers stop working.I can get a screen up, but cannot get the free driver to recognize the fact that I have two monitors.I tried renaming my xorg.conf and rebooting, but that caused my system to stop at startup.

In 11.04 there seems to be several posts regarding dual monitors. When I tested 11.04 prior to making it my os Monitor Preferences detected both of my monitors, as did Nvidia Xserver.
So installed 11.04: After enabling my 2nd monitor using Twinview when I reloaded I get the following in the top right hand corner. (This ss was taken during some testing when I removed my 2nd monitor it shows 3600x1080 when both are plugged in) The Unity desktop or Classic will both load up and I can use the screens just fine. The problem is whenever I put games, or even a ..... video in full screen it breaks is the only way I can put it. I open up Monitor Preferences and it show Uknown Monitor with a resolution of 3600x1080. I can only assume that its trying to make the games etc use that resolution. Tested wow in wine and it shows that res even after I forced it to use my primary at 1920x1080.
I am new to Ubuntu so not sure if Twinview is working as intended but I am guessing not. As I have seen many other with Dual Monitor issues and not sure if this is the same thing. I have no problem using max for windows but anything Full Screen is where the issue is. I have tried setting the positions to "Left of" instead of absolute for the 2nd monitor but it changes back each reboot.

I've just upgraded to 10.04 and even if I am able to use my two displays with my Nvidia GPU, it bugs me that I can't use basic transparency controls on my desktop (compositing in Xfce). I've searched all over google and most links say it's impossible to mix Xinerama with Compositing, while others suggest using the old Xgl implementation will do the trick. I've also read things about Xrandr and that it might be a substitute for Xinerama, but it seems Nvidia drivers doesn't support it.
So, basically, I am at the end of my wits and I wanted to ask (shout?) if anyone managed to: 1. use two displays as part of the same desktop AND use compositing (window transparency) 2. or hack the compositing feature to work with some sort of software acceleration instead of hardware acceleration
Google lists all sorts of solutions, but none conclusive. So, is there a way out of this problem, maybe by using nouveau, or Xrandr, or something else entirely?

I'm building a new Ubuntu system for use as a desktop machine and personal server (http, smb, smtp). It'll be based on an Intel i7 950 and a Gigabyte X58A-UD3R LGA 1366 ATX Motherboard.
I'm looking for recommendations for a graphics card that will support dual monitors and runs well under Ubuntu. Would like some decent 3D support.

I'm currently running 10.10 64-bit version, with the current Nvidia driver installed for my 9600GT graphics card (2x DVI-out). With the card, I am running one VGA monitor and one HDMI TV (both using adaptors). I am running the screens in TwinView, using X Server Settings. My problem is, with the resolution available for my HDTV. In both Windows (XP and 7) and Ubuntu, the current Nvidia drivers all report the native resolution as 1920x1080, this however, is incorrect; the reported native resolution of the TV (according to the manufacturer) is 1280x720; but even set to that, there are still a few pixels missing outside of the screen.
In Windows, the Nvidia Control Panel lets me manually resize the desktop area on the HDTV, to a slightly smaller resolution than 1280x720, so that all pixels are within the viewing area. Is there anyway to do this with Ubuntu, using the current Nvidia driver? I cannot seem to find a way, using Nvidia X Server Settings.

I have searched the web read every post and still i cant seem to get dual monitors working correctly. I have a notebook and a extra external screen at home. Here is my issues
1) My Desktop background stretches over both screens.
2) My Display seems to think I have dual monitors attached permanently.
3) fn + F4 only blacks out screen for a few second.
get this sorted so that when I plug-in the external monitor it works and when I unplug and reboot it goes back to one screen

I am trying to setup Dual monitors with individual (non-mirrored) desktops. AMDCCCLE will only identify the monitor I want to use as primary as number 2 and the monitor I want to use as secondary as number 1 - I have tasksbars, awm, desktop items configured to use the first screen and the second screen is clear for media use. The choice seems to be determined by what output port on my graphic card.. whatever monitor is attached to the HDMI port is called 1. xrandr can only identify the 2nd monitor - the first monitor is unknown I've attached my xorg.conf

I'm busy building a machine now and I'm looking to set up dual monitors because it's something I've always fancied but never had the resources to do. I'm basically looking for advice on choosing a graphics card that will support dual monitors with good driver support under Ubuntu. After a few hours of browsing the forums I determined nVidia were the way to go but I'm honestly not bothered if people want to suggest ATI. I'm not a gamer so really only need the card to support dual monitors. I'll also need to know how to set up the card under Ubuntu and then subsequently how to edit xorg.conf in order to get the dual monitors working.

I have a problem finding the resolution that will fit my secondary monitor(24). If I check "Same image in all monitors" I can only choose resolutions that laptop can display. I don't want laptop monitor to work when I'm using secondary monitor(I close the lid)...
If I want to uncheck "Same image in all monitors"(just to find the right resolution)...the system tells me to log out and back in again. When I do that, there's the same image on both monitors and the checkbox was automatically checked again...
I have an Asus N71J Series laptop. Video card: ATI Mobility Radeon HD 5730 1GB

I've just installed 10.04 on an old system.
Hardware is:
- NVIDIA GeForce 6600 GT video card
- Gigabyte EP35C-DS3R motherboard with 3 gig ram, few TB of hard-drive
- dual monitors, both viewsonic vx2235wm, primary on analog, secondary on digital (but whatever, happy to reverse the order)
On the old setup (8.04) the monitors were set up as twinview, 1680x1050 each, no problems. On the new setup (10.04) my old xorg.conf (see below) doesn't work and nvidia xserver settings refuses to detect my second (digital) monitor at any resolution greater than 640x480.
I've tried messing with xorg.conf to no avail and google doesn't appear to be my friend.
Here's the old xorg.conf file that worked in 8.04 but refuses to even boot under 10.04:

I want to be able to login on different users on my two screens. Is that possible? It would be nice if I could have the left screen and my gf could have the right. I'm using ubuntu 10.04 with gnome, and I have a Nvidia graphics card.

I have a Dell inspiron 1525 laptop with a 1280x800 display and an external 1280x1024 monitor. I'm using 9.04 with openbox. I've done a loooot of online reading about how to get a dual monitor setup using xrandr, and I really don't know what I'm missing here. So here's the deal: I want to have my external monitor on the left of the laptop's display, and of course I want each of them to display different parts of the desktop.
First I set up the right resolution to each one of them (I do it using lxrandr). Typing xrandr -q in a terminal, I get the following:

I have an asus p5kpl-cm MB. I plugged in a radeon 9200 pci card. In the bios, I can set up:
pci/igd
igd/pci
igd
etc.
This determines which of the 2 displays (pci card or internal graphics on the MB) is the boot display. That determines which comes up with the bios screen and then once booted into ubuntu (10.04), this is the only adapter/monitor seen. The button detect monitors doesn't do anything.
lspci sees both my internal and pci card graphics. So, I can get either to work just fine (auto detected etc.) just not both at the same time.
I've tried all of the 3 above settings, and even when I set it to just igd, lspci still sees both my adapters. It identifies them correctly, and it works perfectly, detecting the monitor and knows the resolutions for each - just not both at the same time.
Does ubuntu know how to automatically configure more than one display w/o doing something else, or must I do something else to get both going together?
Code:
$ lspci
00:00.0 Host bridge: Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller (rev 10)
00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 10)

I'm having trouble setting up dual monitors on my HP Pavilion dv7-1020us laptop, with an Nvidia 9600M GT graphics card, and Ubuntu 9.10. I installed Ubuntu via Wubi, on top of Windows 7. I tried this before on the same laptop when I was using Vista and Wubi, and Ubuntu was able to recognize my Graphics card, and install a proprietary driver. I wasn't able to test dual monitors, though. However, now that I'm using W7 and Ubuntu, it cannot use a dual-monitors correctly. It recognizes the monitor, but it only displays a mirror display of my Laptop monitor, not acting as a separate monitor, like I want it to. I tried messing around with the settings in the display menu, but nothing works. I tried downloading linux drivers for my card from Nvidia's site, but the file is in a .run extension, which I don't know how to install. What should I do to get this working?

I have a ATI VisionTek 9250 128mb DMS59 PCI video card that I would like to use for dual monitors on Ubuntu 10.04 Gnome. I installed the card and booted the live cd. Both monitors are recognized when I go to the display settings, but when I un-check the mirror box, nothing changes. I am still only getting one monitor. I was previously using 9.10 and it sometimes worked, but not always.

I have a brand new installation of Ubuntu 10.10. I'm using a GeForce 8600GT graphics chipset. I have two monitors, and my goal here is to have them both working under Ubuntu in their full resolutions, and I've not had any luck with this yet. I've got a Viewsonic VE155s with a native resolution of 1024x768, and a Chimei CMV 221D with a native resolution of 1680x1050. When I first installed Ubuntu, both monitors were working, and the VE155s was working in its native resolution of 1024x768, but the CMV221D was stuck in 640x480.
The Nvidia video configuration utility was not identifying the latter monitor - it only reported it as DFP-0, and doesn't allow any resolution above 640x480 to be set. The mechanism (which has a name which I don't recall) which allows the OS to interrogate the monitor's firmware to find out the monitor manufacturer, model and accepted resolutions and frequencies to use does not seem to have worked. (I previously had the Nvidia driver installed, but I've since switched back to the default open source vesa driver. I won't use the closed Nvidia driver if I don't need to, but if I need to use it to get acceptable performance from this hardware than I will.)
So I did a little bit of reading and I did some hacking of xorg.conf. Previously I had the 15" monitor working in 1024x768 and the 22"
monitor working in 640x480. Now I've got the 22" monitor working in 1680x1050 as desired, and the 15" monitor not working at all. Here's a copy of my xorg.conf. For the sake of brevity I have not included the unnecessary bits such as input devices.
Code:
Section "Device"
Identifier "NVidia"
#Driver "nvidia"

I'm trying to set up my monitor and tv for dual display but I'm having some problems. I want them to display the same thing so I've enabled twinview and I figured the second display position should be set as clone but when I save xorg and restart the x server the position reverts to absolute. Anyway, the monitor is set as the primary display and it's the one I'm having problems with. The tv is fine but the monitor's display is stretched off the screen so I can't see the far right or bottom of the screen. I'm very new to linux and I'm just finding my feet so if there's any other info needed you'll probably have to be very specific.

I have a thinkpad T43 with a dock and a 19" Dell monitor attached. Im trying to get an extended desktop.Using the default display program (using ubuntu 9.10) I can mirror the screens just fine. But, when I click the radio button to enable the extended desktop, the monitors (both of them) go black. Some times it doesn't come out of this. (yes, I'm waiting more than 25 seconds) What can I do to make the extended desktop work? here is my display info from the command lshw:

I've been searching around and from what I've found this is supposed to just work but I am having some display issues when cloning my laptop to an external monitor. I think the problem is that my laptop has a better resolution than the monitor. Here is my setup:
laptop with a display of 1900x1200
external monitor with a display of 1680x1050
ideally I want to clone the laptops output onto the external monitor so they can both operate in their native resolution. When I setup twinview and set it to clone the laptop displays correctly, however, the external monitor is missing a large chunk on the bottom and right hand side
here's my xorg.conf
Code:
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 1.0 (buildd@palmer) Fri Apr 9 10:35:18 UTC 2010
Section "ServerLayout"
Identifier "Layout0"
Screen 0 "Screen0" 0 0

Does anyone know of problems where 10.10 doesn't recognise more than one monitor? I've got nVidia 8500GT and I have the 'recommended' proprietary driver installed. I upgraded from 10.04, and dual monitor was working -> restarted -> dual monitor not working.

I'm currently running Ubuntu 10.10 on my HP laptop with an external monitor attached. I've been having the same issue since 9.04 and just now figured I should ask about it.When I have dual monitors set up (extended desktop) the mouse speed in the X direction seems to double. ie. assume the mouse usually moves 1 pixel at a time, it now moves 2. It seems to be functioning as usual in the Y direction, which makes the motion really weird and hard to use. I'm using a Wacom tablet for the mouse, but the same happens with my laptops touch pad. Anyone else experience this/know how to fix it?

I have a dual setup and just switched from Xubuntus Xfce? to Fluxbox... But now I can't set wallpapers on both my screens anymore. How do I do that? I had to change the Fluxbox menu from Head 1 to Head 2 to get it on my bigger, primary screen. Which is the one getting a wallpaper when I'm setting one.
Here's my xorg.conf:
