Ubuntu Multimedia :: Can't Seem To Get Dual Monitor To Work ?
Jan 5, 2010
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 have installed Ubuntu 9.10 on my laptop Lenovo T60. The problem is i can't make extended monitor in that way: laptop 1024x768 and Monitor LG L1952HQ 1280x1024. If i make this configuration, screens appear black and i can't go back without restarting. Presently system support only: laptop 1024x768 and LG L1952HQ 800x600. This configuration (laptop 1024x768 and LG L1952HQ 1280x1024) worked well previously with the same ubuntu 9.10 before reinstallation. I guess i should reinstall ore change to other video drivers? The refresh rate is set on 60 Hz.
I am running a 2.7Gh with 2G ram with an ATI X1300/1550 Radeon Card and running with dual monitors. I had the monitors functioning in Linux Mint but it was an older driver version and it was slow. I was reading about the Ubuntu Maverick 32bit and fresh installed it I have just installed Ubuntu 10.10 Maverick 32bit. Everything that I have found on here concerning ATI and fglxr has not worked.
Pressing left, middle and right button of mouse at bottom and right edges or bottom left, top right and bottom right corners of the screen does not work with fittstool-2.0 on openbox in debian jessie with dual monitor.
Pressing left, middle and right button of mouse at top and left edges and top-left corner on the screen works correctly.
I use openbox on debian jessie. I do not install any desktop environment explicitly.
In the jessie, I installed gcc, make, libglib2.0-0, pkg-config, libcairo2-dev and libxcb1-dev.
I downloaded [URL] .... and confirmed that the sha1sum value of the downloaded file matches sha1sum value given at [URL] ....
I expanded the downloaded file by Code: Select alltar -xvf fittstool-2.0.tar.gz into fittstool-2.0 directory.
I executed with an ordinary (non-root) user: Code: Select allcd fittstool-2.0 make
I executed with root privilege on the fittstool-2.0 directory Code: Select allmake install
I executed the following with the ordinary user: Code: Select allfittstool and ~/.config/fittstool/fittstoolrc was generated.
I modified it as Code: Select all[TopLeft] LeftButton=gnome-terminal MiddleButton=pcmanfm RightButton=iceweasel
[Code] ....

I have a Intel DQ35JOE motherboard with integrated video (DVI and VGA). I've been running Ubuntu 8.10 for at least a year with both monitors working fine. One is a Hanns-G 27.5 inch, the other (VGA) is an older AOC 19". They were both plugged into the motherboard video plugs (it had both), and they worked side-by-side (not mirrored) just fine on 8.10.Last night I decided to go ahead and take the plunge and upgrade to the latest, because I run 9.10 on my laptop and love a lot of the new stuff. The reason I hadn't upgraded was because I feared the potential problems - which I ran into head-on this time.
Upgrade to 9.04 seemed to go fine. Then I immediately did the upgrade to 9.10. Unfortunately, my screens came up upside down and backwards. And the mouse moved the wrong way. And to click on something in the top left of the screen, I had to have my mouse on the bottom right of the screen.Well, I also received a warning that my primary hard disk was failing. So, I decided to just do a clean install of 9.10 on a new disk that I had handy - hoping it would be better if it was a clean install rather than an upgrade.
Now I can't get dual monitor to work at all, and Ubuntu seems to not recognize my monitors. If I just plug one monitor in, it works. But it won't let me adjust resolution above 1280x1024 (my big one is 1920x1200). And it says "unknown" instead of identifying the monitor.Also - at one point both monitors were appearing (but "unknown"), but mirrored, and whenever I uncheck "mirror screens" and click apply, the screen just goes black with a frozen cursor - and I can't even do CTRL-ALT-F6 to get to a terminal - it just freezes the whole computer.
When ever I install the (recommended) drivers through the "Additional Drivers" interface to run Unity my dual monitor setup does not work. The monitors won't even detect correctly what so ever. Then, when ever I install (more basic?) nVidia drivers through the packet manager, my dual monitors work as planned, but now Unity won't work. What's the deal? Are there any work arounds for this?
I have just upgraded from Fedora 11 to Fedora 13 and now can't get my two monitors working as a single "screen" (it worked under F11). I have a GeForce video card with two monitor outputs
I then edit the xorg.conf to change the driver from nouveau to nv and I can start X and the LCD displays the desktop at a resolution of 1680x1050 (good) but the CRT just displays random blocks of colour. At this point I also get a kernel crash - see dmesg output attached, but the system is then OK to use. I have tried editing the xorg.conf to add a second monitor and a virtual screen resolution to match the two monitors (1024x768 + 1680x1050) combined (2704x1050) but still only the LCD monitor works, but with the virtual desktop that can be nudged around with the mouse. I would like to get back to using both monitors with a virtual screen across the two monitors.
I've been troubleshooting a friends computer and we've pretty well hit a brick wall. The issue at hand is the video card will not output properly. To be specific, it's an NVidia card with both DVI and VGA ports. We want it to output via the VGA and ignore the DVI because there's nothing plugged in there (the monitor we want to use doesn't support DVI). At any rate, the only time we can get the VGA to work is when we have another monitor plugged into the DVI port and dual head the system. When we do this it also adds an extra "Unknown Monitor" to the display panel. When we just use the DVI the extra "monitor" disappears. now we don't want to have monitor sitting here useless just so we can use the vga out, but there seems little else to do. We tried installing the Nvidia proprietary drivers through the software manager and yum and it failed both ways.
This is really frustrating because it seems like it should be such a simple thing but nothing works. Does anyone else have similar issues? is there something i can do to fix this? I apologize if i've not provided enough info, but ask and i'll post anything you need to diagnose.
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?
I have tried to setup a workstation with 3 monitors on two ati videocards, the goal being to span the desktop across all of them.
The process was not difficult at all, but after login X11 crashes and I am left with a console. I am fortunately able to login in safe mode, but I would like to ask for help in debugging this issue.
Here I will try to give as much detail as possible, starting with my system specifications:
Code:
The first card, the ATI Radeon HD 4650 is capable of running two monitors at the same time. The monitors, for all it matters, are three identical ACER P206HV 20" connected with their analog interface (due to missing cables which I will buy soon). Resolution 1600x900 each. My motherboard is an AsRock 870 Extreme3 mounting an AMD Athlon II X4 640 3 GHz processor and 8 GB of RAM.
When asked by Ubuntu, I installed the ATI Caralyst driver version 11.6 and set it up for using Xinerama.
As I said, this setup works fine if I login in safe mode, but crashes X11 otherwise (even in classical mode - no Unity). By inspecting the logs (attached) I found this (notice the segfault)
Code:
As a test, I tryed to configure Catalyst without Xinerama, an this works, but of course I end up with two separate desktop, which is not what I want. In this mode, xrandr seems to work correctly
Code:
After some research I found that XRandR does not support desktop spanning over multiple GPUs, so Xinerama is the only way to go in my case. Since the two are not compatible with each other, after login in safe mode I see that XRandR is disabled
Code:
One more test consisted in disabling the XRandR module in the config files, as found in some posts: edits in /etc/X11/xorg.conf
I'm having a rather hard time getting my 3 monitors setup as one display. I can get all three to work without too much heartburn using 3 separate X instances. The monitors are on 2 different video cards, one dual heads. The other on it's own card.
I've tried countless ways to get this to work, and I'm just not feeling the love. There are 2 17 inch monitors on the 1 video card and then the second video card has a 24 inch monitor on it. I can get the two monitors on one head to work with twinview, but the third one is left out.
The physical configuration looks like this..
17inch on the left of the 24 inch monitor, and another 17 inch monitor on the right, with the 24 inch monitor being in the center.
I'm going to include my current xorg.conf and lspci.

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'm trying to set up a dual monitor system with my Dell E7450 laptop with Debian Stretch and KDE 4.14.2. The graphic card is a Intel HD5500 with xserver-xorg-video-intel version 2:2.99.917-2. The first time I simply connected the HDMI plug, it recognized the monitor and it automagically set up the extended dual monitor. Then I unplugged the HDMI and KDE froze. Now every time I plug in the second monitor the laptop monitor goes black, the desktop goes on the external monitor and the mouse cursor moves only vertically along the leftmost edge of the monitor.
When Karmic came along, I upgraded and it was possible for the first time to get a dual monitor display working using only the GUI apps supplied. (I think I used screen resolution) It worked out of the box and took no time whatsoever.
I had a dual monitor set up working with 2 1024 x 768 monitors, with a desktop spanning both, and a background picture doing the same.
The Lucid update has just spectacularly broken this, along with a large number of desktop type changes that were unwanted.
The version of Ubuntu was the usual vanilla, but with enough K stuff installed to make K3b work. The card is a Radeon 9250SE.
Give up and re-install Karmic? Wait for some sort of upgrade to allow either Monitors or Multiple Screens to work - the option to remove cloning is greyed out in one and unticking clone in the other does nothing? Try some other distro?
Does anyone know of a decision to remove any functionality from Lucid that existed in Karmic? Is there any useful background to this that is perhaps not obvious?
I recently got a signal conversion box so I could route my netbooks monitor-out port to my TV. The idea being that I could effectively set the TV up as a separate monitor for watching movies on whilst I worked using the netbooks own monitor. It seemed to work initially, the Monitors dialog box could easily detect and setup the TV as if it were just an external monitor however I can't seem to play any kind of video on either screen when this is set up. All I get in Totem, Mplayer, VLC and skype is just a black area within the applications window. The sound works fine so this is clearly just a video problem.
It only seems to occur when I configure the system to use the TV as a separate monitor. If I tell it to display the same thing on both monitors all video output works fine.
prior to showing the GNOME user logon screen. Unfortunately, all information I seem to be able to find on this appears to be relevant for pre-systemd Linux only.
The situation is that I have two monitors: One small tilted monitor on the left with 1024 x 768 which should be secondary and one larger landscape monitor on the right with 1920 x 1080 which should be secondary. Everything works persistently AFTER a user has logged on. However, after booting the system or after changing users, the small monitor becomes primary so (a) the user needs to logon using that monitor and (b) as the monitor is physically tilted, one needs to tilt the head to read it wihtout the xrandr commands.
If I can get beyond this issue, there is a second issue: While one can pick the primary and secondary monitor in Gnome, monitor numbers 1 and 2 seem to be fixed. This becomes a problem when using freeRDP to connect to a Windows server with dual monitors. Then, the smaller, secondary monitor is number 1 and thus, it is the Windows logon and primary screen. Is there a way to switch numbers 1 and 2 in Linux, for example somewhere in the grub configuration?
with KDE everything works fine (both monitor show their configured displays correctly), however oddly with gnome when i try and setup dual monitor display, i get blank screens on both monitors, however on the display 0 on the left side there is a full column single pixel width green strip. the rest of display 0 and 1 are blank, however my mouse will move around both display correctly.
I've played around with a second monitor, but so far I haven't found a satisfying solution. I am using a laptop with a GeForce 9600M GS graphics card. I have managed to set up twinview, but my monitors don't have the same height so I'd rather have something like the "seperate x screen" option. Or how I imagine that option would be like. After some problems with the nvidia configuration tool (I couldn't change the xorg.conf, until I read this: [URL] I now have two separate screens, but the second one is all empty, with black background and X-shaped mouse cursor.
There seems to be no window manager running, I can start programs there with -display :0.1 , but they don't get any frame decoration and, which is worse, no keyboard focus. I'd be fine with a fullscreen konsole there, so I don't really need a window manager, but I do need access from the keyboard. I'd prefer a setup that would allow me to easily (without editing xorg.conf) switch between using both monitors and using only one, because I don't always use the laptop at home.
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 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.
Just installed Debian 8, coming from Ubuntu12, it seems I cannot get my dual monitors to work as it should.
I want two monitors side by side, currently I have two identical outputs. I looked around a bit and register two possible problems.
root@bigcem101-debian:/home/bigcem101# xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 640 x 400, current 1024 x 768, maximum 1024 x 768 default connected primary 1024x768+0+0 0mm x 0mm
Hence, problem 1: it is as if there is only one monitor detected. Then I tried to look for Xorg.conf ..... and: problem 2 xorg.conf is not there. This seems to be normal but when I installed my Ubuntu years ago it was still there and one could manually set things. There must be something new I am missing.

I just switched from Ubuntu to Debian and I am having trouble doing something that I found easy to do with Ubuntu. I have a Radeon R9 graphics card from MSI with dual DVI ports and I'm trying to get xrandr/arandr to detect my dual monitors but it only detects one. I've installed all the drivers and even installed the "amdgpu" driver from the Ubuntu repository but still not detecting. What drivers am I missing?
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 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 dual-screen set-up with Ubuntu 10.10. I have an ATI Mobility Radeon HD 5650 video card. I use my lower-resolution laptop screen on the left and a larger monitor on the right. The monitor is also physically higher than the monitor. See attachment for a screenshot.I have correctly set up my displays so that if the mouse is in the middle of the screen it can move from one screen to the other without jumping. The jumping happens when moving off of one screen in an area where the other screen is not directly next to it (some people call this 'the void').
Example: (See the attachment for a visual example of this.) My mouse is in the external monitor (right monitor). As I move the mouse to the top-left of the monitor (position 1), I by mistake go a little too far and instead of hitting the Ubuntu applications menu, I ended up at the top-right of the laptop monitor (left monitor; position 2). I quickly realize my mistake and move the mouse back to the right monitor, but now the mouse is at the middle-left position (position 3).This same error occurs by moving the mouse on the laptop monitor (left monitor) passed the bottom-right position. This is a big problem when scrolling vertical scroll bars on the laptop monitor (left monitor).I am looking for a fix that if the mouse is at position 1 in the attachment and I move the mouse left, it stays at position 1 and does not go to position 2.
my laptop screen has 1900x1280 (native resolution) and my second monitor has 1600x1080
After browsing the forums and messing around with drivers I managed to get the resolution up to 1600x1080 (from 1000x800 at install) on the laptop screen. No luck at all with the second monitor. I currently have it connected with both VGA and DVI.
my understanding is I need to use twin view to setup the second monitor. I've read several of the earlier posts but haven't been able to get it to work. Here is my current xorg.conf file:
I'm trying to get dual monitors working on a fresh install of debian from the netinst install cd. I did not allow the installer to download any packages and then manually installed xorg gnome-core & gdm using apt-get.
The monitors are plugged into the onboard vga and dvi ports of my motherboard. I believe the chipset is intel.
