Ubuntu Multimedia :: Getting Dual Monitor Support Working In Unity With NVIDIA?
Jun 21, 2011
I have an NVIDIA 9800 GTX. I have 2 DELL monitors connect to this card, one is a 24" and the other is 21".
I am unable to use Xinerama mode with Unity, because for some reason after logging in, I get no desktop interface, only background wallpaper, and I have to force reboot.
How can I setup dual monitors in Ubuntu using Unity properly? Note that I do NOT want to use TwinView, since this results in dead space around the smaller monitor.

How can i be able to enable dynamically my second monitor and use Unity at the same time?Summary system:HP Compaq 8710p laptop, Nvidia Quadra 320M, Natty 64bit, with attached 2nd 19" monitorDescription steps taken this far:By default ubuntu ships with the following xorg.conf conform the new minimalist trend:
Code:
Section "Device"
Identifier "Default Device"
Option "NoLogo" "True"
EndSection
I use the nvidia-current binary drivers. In this configuration:Unity works Xrandr sees 1 screen (so no configuration of second screen possible)Standard monitor configuration tool in Ubuntu shows 1 screen With [URL]
Code:
disper -d auto -e
my second monitor comes alive. My laptopscreen becomes dark (with moving mouse cursor). Unity / Ubuntu classic (no effects) go into scrambled mode. Mouse is moving, objects are

I've managed to get dual monitor support working, but it seems a little sub-standard.
- I can't find how to alter the relative y offsets of each screen
- I can't drag windows from one side to the other

I have an Acer 1200X with an Nvidia 8200 graphics GPU integrated on the motherboard. I have an HDMI and VGA output. I have downloaded the Nvidia graphics driver using envyNG and the old fashioned way. I have tried configuring the monitors 15 ways from Sunday in the configuration and I cannot for the life of me get dual monitors to work.
When I go into configuration with the Nvidia wizzard it blanks like its going to work then just stays black with the mouse cursor. I also cannot save as I get a "parsing" error. I am using Ubuntu 9.10 and have even tried using envyNG to get the monitors to work on twinview... NOTHING Hope someone can help!
My dad who is a Linux nut came over to help and he left 3 hours later because were tempted to chuck the computer out the window...I need to figure this out as this is going to be my work computer and I need dual screens.

I have a Dell XPS M1330, which has a GeForce 8400M GS GPU. The binary (sigh) nVidia driver installed is version 190.53 (installed by sgfxi). This is working well: glxgears gives me about 2600 FPS and compiz is happy.An old Philips 170B is attached by VGA cable. I was looking to set up a method of switching resolution upon connecting to the monitor when working at the desk, since I don't like the 1280x800 resolution of the laptop.
nfortunately, I can't get any output on the external monitor. It does work under Ubuntu, which installed the 180 series binary driver. (Going to an earlier driver is an option, but I want to understand the problem.) Bottom line, I want to work under Debian.As far as I know, nVidia's proprietary driver doesn't support xrandr. At any rate, with he external 170B monitor attached and turned on, I get the following:$ xrandr -qScreen 0: minimum 320 x 175, current 1280 x 800, maximum 1280 x 800default connected 1280x800+0+0 0mm x 0mm
1280x800 50.0*
1024x768 51.0 52.0
960x540 53.0

just setup suse 11.3 , put on the Nvidia 19.29-22.1 drivers via yast , no kms is set in inetd , nomodeset on grub boot line etc... Even tried installing the driver " the hard way " dual monitors come up, setup xinerama to "Extend" my desktop , and the main monitor ( right side ) is good, visually the left monitor (2ndary) is good.. but whenever I move my mouse over to the left screen the mouse pointer dissapears, flickers along the right hand border of that screen... and if i move the cursor back to the original screen i have to really fight to get it back to the main screen....Copy of my xorg.conf , still very basic...

I have an external monitor attached trough a VGA cable to my laptop PC, with the monitor settings shown below. The problem is that when I have the external display connected, video players such as VLC or MPlayer display a black screen instead of the video, with only the sounds working. If I unplug the monitor everything works fine.
Setup Specs:
Dist: Debian Wheezy
Kernel: Linux 2.6.32-5-686
Gnome Version: 2.30.2
Laptop: Asus Eee PC 1000HE (10" LCD screen)
External Monitor: LG Flatron Wide L204WT, 20'' Widescreen LCD Monitor

I have been using ubuntu for quite a long time, and for the first time, I am now unable to set nvidia drivers to work. I have just install ubuntu 9.10 amd64 on an AMD 64 athlong X2 with a GEForce 6500 nvidia card.
The only reason I need the proprietary drivers is to use two monitors.
I am going crazy, I have tested everything I have found on the web. I have tried all the nvidia drivers version, I have tried envyng, ... but nvidia do not work!!
I am trying Xinerama with nv, but it does not work either!!!
Here is my xorg.conf file in which I have tried to use nv driver to set dual monitor. X fails to load and it says that screen 0 is deleted, that devices are found but there are no matches in the config file. Any clue?
Section "Files"
ModulePath "/usr/lib/xorg/modules"
FontPath "/usr/share/fonts/X11/misc"
FontPath "/usr/share/fonts/X11/cyrillic"
FontPath "/usr/share/fonts/X11/100dpi/:unscaled"
FontPath "/usr/share/fonts/X11/75dpi/:unscaled"

The title says most of it. I've got an Optiplex 755 (Dual 20" Dell Monitors) on my desk at work but have access to a 780 if I want it. The 755 does NOT work with Unity, simply won't handle it. I'm not interested in doing an OS Reinstall and data transfer of all my work stuff if Unity doesn't work (KDE is fine on my 755...well sort of, I have Konsole windows popping up through my Firefox and KRDC windows but that's a somewhat minor issue). Anyone have an Optiplex 780 that they have the most recent Ubuntu installed with Unity running (Dual Screen) without a problem?

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:

Since my upgrade to 9.10 I can't expand my windows over two monitors anymore.
I'm using the NVidia software, external drivers and everything was working before.
Is there something I missed during the upgrade?

Currently I have two 1920x1080 screens running in Twinview on my Geforce 275 graphics card. Want I want to do is a quick simple way of disabling my secondary monitor when playing video games or using xbmc to watch movies, etc. I've tried a few applets but they require the xandr function which I think Nvidia doesn't support.
Is there a way to disable this quickly other than loading up nvidia-settings and disabling the monitor everytime. I don't really want to use two seperate x sessions and xinerama due to the fact you can't use compositing.

I wanted to know how to save the dual monitor using Nvidia X server Manager. I googled how to and it said to delete the "xorg.conf" However I dont have the Permission to delete this file so I would also need to know how to gain full admin access to my Ubuntu Account.

I've just installed Ubuntu on my laptop. My laptop has an nVidia card so I'm forced to use the nVidia configuration tools. What I'd like to happen is for it to automatically start using my monitors if they're detected. OR, make a simple script that will enable the monitors without needing to restart X.

First off, let me say: I'm a long time Linux hobbyist and recently installed Fedora 12. I've been looking (some say "lurking") around these forums for a bit after I loaded it up and let me say: Leigh, You're an amazing young man! Keep up the great work! I've a question: I've just put together a hobby computer: Pentuim 4, with 1 Gig of RAM and a Nvidia Geforce5700LE. When I install Fedora from a fresh install, everything works great: nice screen resolution, good graphics, etc. but no 3d or acceleration, so I'm very limited on my programs.
So I decided I need to upgrade my Nvidia driver. I followed Leigh's Nvidia setup guide after installing Fedora 12 (all four steps!) everything seemed to go fine, but when I reboot, I quickly see the Nvidia splash screen, but the screen then goes blank. Well, not really blank, I can see what appears to be a kind of cross-hatch pattern, plus I can see what should be my mouse cursor on screen (it also is a square shaped pattern). I suspect it may be at a screen resolution that my monitor doesn't support. Once there, the computer pretty much doesn't do anything else. Usually I can break into the x driver loading and go to the command prompt, but this latest time I can't even do that.

I have recently installed FC15 on my system. Dual monitor support seems to be broken with my setup. I am using the latest NVIDIA binary blob driver (270.41.19). I compiled my own kernel for it, version 2.6.39.
When gnome3 starts it almost manages to boot up, but then it crashes and gives me the option of logging out. I have my system booting into target 'multi-user.target' since I was doing some other stuff and I use `startx' to start gnome3. I tried running having X use xinerama and not use xinerama, both cause gnome3 to crash, albeit in different ways. Other than that I am running a stock install as far as I know.
If there are some logs I should be looking at for gnome3.

I am trying to install nVidia drivers on CentOS 5.4 and it is requiring kernel-source
# lspci | grep VGA

Only reason to install the proper driver is to use dual monitor.

I have the nVidia GeForce 8500 GT 512MB graphics card, I put it in my system to get a speed boost and for a dual monitor setup, I don't have the proprietary drivers installed I tried installing them, and when I did it asked for reboot, so I did, and when it came back up only one monitor was in use, and it was running very very sluggish, so I opened up the Monitors from the settings and it said to use nVidia's thing, so when I did, I enabled the second monitor, and hit apply, and it asked for a restart of Xorg, doing that came back telling me that no monitors were find, and a reboot brings me straight to tty1... I tried both the recent version and the older one, both did the same thing, I really wanna get my Compiz effects back. is there a way to get this working? I will do anything you ask if it solves the problem...

I used preupgrade to upgrade from F11 to F12. In F11, I used the proprietary nVidia drivers from rpmfusion, and they worked well. I have refrained from installing the nVidia drivers in F12, because of the problems reported for users of KDE. I removed my old xorg.conf, which has references to the nVidia driver and to "TwinView," the proprietary method of managing two screens, so as to let X discover both monitors.
Now, however, my second monitor stays black, even though xrandr and KDE RandR show both monitors correctly. Xorg.0.log shows the nouveau driver is loaded. (I also tried to create a new xorg.conf following guidelines from the web, but many of the guidelines are from before xrandr, and I'm not confident I have it right yet.) It seems that X believes I have two monitors, because I can drag a window off into the blackness (and it's never heard from again!) I know that the hardware is working, because I just booted into Windows 7, and I could see the desktop on both windows.
How do I convince X and KDE to display on both monitors?

I run opensuse 11.3/kde desktop.
- updated to KDE:Factory
- X11 repository (V1.9.3)
- proprietary nvidia drivers (260.19.36)
Video card is a Quadro NVS 290. A dual head configuration using twinview is run.
The desktop becomes slow almost immediately (couple of seconds) after logging in (all applications). Turning off desktop effects does not make a difference as well as trying the various recipes on the internet regarding x.org conf-files.
The only action restoring responsiveness is to simply start nvidia-settings. Putting the following pseudo-action into a script-file and mapping it to a key allows to have a workable environment:
nvidia-settings -a PixmapCache=0 && nvidia-settings -a PixmapCache=1
It is very annoying having to press a key every minute or so. Instead of creating a cronjob I would like to solve this issue. This behavior has been consistent across kde/x-org/nvidia/kernel updates for many month now.

I have Ubuntu 9.10 installed on my computer. I also have Galaxy (Nvidia) 9500 GT PCI-E card installed on it. I can get both monitors (Acer X223w) to work but every time I shut off the computer and turn it back on the second monitor is shut off. I just need to turn it back on using Nvidia X Server Settings. I have tried to save my X configuratin file but I keep getting an error of:" Unable to remove old X config backup file '/etc/X11/xorg.conf.backup'. I have a feeling this is because I am not signed in as root. Is this correct? If this is the case is there a way to get to sign in as root not using the command lines? Otherwise they need to remove this button. I can manually create a backup (copy paste into a text file). I think. Getting back to my Xorg.conf file, I think I need to modify it to have two screens. I have also got some information on my video card using the lspci command. I think I need some information from this. I have written below (towards the bottom) what I think the file should be. Now before I do this, does anybody know of an easy way to back up my whole computer? With my luck I am about to screw something up big time. I think I can just get away with the text file that I copied from the Xorg. Worst case scenario I will just manually replace the file.
Information on my computer:
OS: Ubuntu 9.10 32bit
Motherboard: ASUS M3A78
CPU: AMD Phenom 9500 Quad Core
Video Card: Galaxy Geforce 9500 GT 1GB 128 bit DDR2 (Nvidia)
Hard Drive: Hitachi 1 TB Sata Drive 3 Gb/sec 7200 RPM
Ram: 4 GB (I think, its been awhile since I built this thing)
DVD Burner: LG
Here is a copy of my xorg.conf file: (I don't think it matters but I have both monitors turned on right now).
from the lspci | grep VGA:
I think I need the 01:00 information for my Bus ID. The only thing that I am confuse on is that I was expecting to see two of them.
Okay, this is what I think I need to do: I tried to add color to make it easier to find the changes I made but for some reason I cannot. I will add **** on the end (right side) so my additions and questions will be easier to find.
Do I need to add another Device for the video? Doesn't make sense to me since I only have one video card. I was told it should be based on the # of chips on the card. So I guess I should have two of them since I have two outputs.

I have repeatedly installed CentOS 5.5 64-bit on a Dell T3500 with an nVidia Quadro FX 580, in an attempt to get dual monitor support to work to no avail. Everything works fine when just one monitor is plugged in and I do not try to enable or plug in a second monitor. I have installed the Dell DKMS, and the Dell recommended drivers (from Dell site) on one installation, I installed the nVidia drivers (from nVidia site) on another, and have tried with what CentOS loads by default on another. The results are the same every time: When I reboot as directed I get a black screen. I can recover by hard shutdown and unplugging one of the monitors, but that doesn't solve my problem. Has anyone had a similar experience, or have any helpful guidance? I am not very Linux savvy. This is for multiple machines in a corporate environment.

I have activated dual screen monitors using the Nvidia driver GUI as Sax2 would not correctly configure it. Now at every boot I get the message "undefined video mode 31a, press [enter] for a list of video modes or [space] to continue. After pressing space the system boots to my liking, how can I get rid of the message at every boot up?
I am using Suse 11.2 and KDE4.3.1 My video card is an Nvidia Geforce 7100 GS I thought I was using the Nvidia drivers as I have a GUI from Nvidia in my launch menu if I search "Nvidia" and I have completed the one-click installation. Although when I go into "My Computer" it says driver unknown.

Earlier in natty this was working completely. It's only just started happening about a week ago. I don't know what changed, all I know is it suddenly stopped working. Basically the bar at the top is still there but there is black underneath. I can put windows there but I cannot see them (Just black). If I click on an indicator it looks on the bar as if it is being clicked but I cannot see the menu. I have attached a screenshot.

I know there are a lot of dual monitor threads.I've read them, and I even checked at the nvidia forum.I don't see something similar enough to my problem so I'm thinking maybe it's not a driver issue.I'm running F12, both monitors were working and I configured them properly and they were fine.Yesterday I installed the nvidia drivers as per Leigh's tutorial.Once I got that sorted out and rebooted, my secondary monitor was no longer registering.I checked in display settings and it does not recognize the second monitor.I tried going to system->administration->display but after I authenticate nothing happens.

I am on kubuntu 9.10 x86_64
I just got my new video card: nvidia 9500 GT to setup dual monitors.
The video card has 2 dvi output to support dual monitors
Monitor 1 is connect to dvi
Monitor 2 is connect to dvi using a vga adaptor
I can't seem to get dual monitor to work?
From system settings -> monitor, i see 2 vid outputs one is DVI0, the other is VGA2. what's odd is i can set up different screen resolution for each monitor, but I only see one desktop, both monitors show the same desktop.
How do i get each monitor to show it's own desktop?

I noticed in the new Ubuntu 11.04 with Unity, when in dual monitor the icon of skype is not placed in the tray when "closed". It is only placed in the background, so that I have to kill the process and open a new one. To be sincere, I see a strange aspect of the entire tray when in dual monitor. Is anyone else noticing the same?
