Ubuntu Multimedia :: Dual Monitor - Same Image On Both Monitors Stays Checked ?

Feb 15, 2011

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

Ubuntu :: Dual Monitors: Fullscreen Goes On The Wrong Monitor?

Apr 11, 2010

I've got a dual monitor setup. The primary one is 1360*768 and the other is 1024*768. When I fullscreen a video on the web [URL] it fullscreens to the smaller (non-primary) monitor, but cuts some off the right hand side, as if it is fullscreening the right size to display on the bigger monitor, but instead does it on the smaller one. It happens with any web video, if I click the fullscreen button on the player, it moves it fullscreen to the other monitor.

Fedora Hardware :: F12 Upgrade - NVidia Card - Dual Monitors - Only One Monitor

Nov 26, 2009

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?

OpenSUSE Hardware :: 11.4 Dual Monitors - Left Monitor Not Coming Out Of Powersave?

Sep 7, 2011

I have a really strange X (?) problem. My physical setup is:

Dell Optiplex 990
VisionTek 210 nV DMS59 PCIe video card (with a DVI splitter)
dual Dell P2411H monitors

I'm running OpenSuSE 11.4 (x86_64 fully patched) with the current nvidia drivers and kernel module. I'm running KDE and kdm in case that matters.

If I power off the two monitors, and then power them on again, the right monitor will come back on. The left monitor (which is the primary one... it's the one where the login screen appears when you are first logging in) reports that it is in power save mode. Wiggling the mouse, typing, etc., do not wake it up. The only thing that wakes it up is the detach the DVI cable from the monitor and reattach it (and sometimes it takes a couple tries).

I have used two (identical) video cards and splitters, and the problem occurred with both, so the problem doesn't appear to be with either of them. I also swapped monitors, but after the swap, the problem still occurred on the left monitor, and the old left monitor (which was now right) came on fine, so it doesn't appear to be a monitor problem.

I'm baffled. For now, I just won't turn off the monitors (or at least not the left monitor).

Hardware :: Dual Monitors Nvidia 9500 GT - Turn On The 2nd Monitor After Startup ?

Feb 25, 2010

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.

Software :: Dual Monitors - Make An Application Automatically Open On Second Monitor?

Jul 20, 2011

I am using Fedora 15 with dual monitors. I want to make an application open automatically on the second monitor. In particular I would like to make Firefox open on the second monitor. For now I am just manually moving Firefox to the second monitor, but if I close it down and open it again, it automatically opens on the first monitor. Is there a way to make it automatically open on the second monitor?

I have two Nvidia cards in my machine. I did have one monitor connected to each video card, but I was unable to get a dual monitor set up to work like this, so I plugged both monitors into one card and the dual monitor set up works fine like. Is there a way to make dual monitors work if you have a monitor connected to each video card? When I had a monitor connected to each video card, I could see the second monitor in the Nvidia settings, but it always disabled it. I could enable it, but it would grey out twin view. After I enabled it, I'll restart the X server, the second monitor would auto disable again.

I'm using Gnome, I don't have the above issue in Xfce4 - it works fine with one monitor connected to each card in Xfce4. However, I want to use Gnome. I've searched, but have not been able to find a solution to either of these issues. I read you can fix the application to launch in a second monitor with wmctrl. I've tried to install it with yum, but I get the message: No package wmctrl available.

Software :: When Dual Monitors Enabled, Task Bar Moves To Wrong Monitor?

Oct 24, 2010

I am using Mandriva 2010.1 and KDE4. The primary monitor is VGA-0, and sometimes it's desired to play a video on the big monitor which is HDMI-0. I use an xrandr command line which works nicely except that the KDE4 task bar and desktop icons move over to HDMI-0. How can I keep the task bar and desktop icons on VGA-0 when both monitors are enabled?

Code:
xrandr --output VGA-0 --mode 1024x768 --rotate normal --pos 0x0 --output HDMI-0 --mode 1920x1080 --rotate normal --right-of VGA-0 --pos 1024x0

Ubuntu :: Dual Monitors - Swap "monitor 0" And "monitor 1"?

Feb 11, 2011

With a dual-monitor setup, how can I control which monitor gets which id number?

My primary monitor is a 24-incher. Recently I picked up a little 10" flat panel for a project. The dual-monitor setup is mostly working fine, in that I can move windows between the two monitors, change the alignment in Monitor preferences, set resolutions, etc. Unfortunately the little monitor is getting assigned Monitor 0 and the 24" is getting Monitor 1, so the panels are showing up in the wrong place.

I can work around by going into gconf-editor and telling the panels to use Monitor 1, but I'd like a better fix. Changing monitor assignments seems the obvious right way to go, but I could be wrong.

Setup:
- Ubuntu 10.10
- Core i3-550 using on-chip graphics
- Intel DH55HC with VGA/D-sub, DVI, HDMI
- No-name 10" flat panel connected to VGA/D-sub (has VGA only)
- Acer 24" flat panel connected on DVI (has VGA and HDMI ports too)

My SWAG is that the system is simply assigning Monitor 0 to the VGA port. The 10" is VGA/D-sub only, so I can't physically swap them to test this (FWIW I did move the 24" to HDMI and the results were the same).

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.

Ubuntu Multimedia :: 10.10 And Nvidia With Dual Monitors?

Apr 11, 2011

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.

Ubuntu :: Killed Xserver / Gnome - Cursor Stays At The Left When 2 Monitors Connected

Mar 5, 2011

i somehow screwed my xserver (I guess it is the xserver). I got the following problem:

1) When i have 2 monitors connected, the cursor stays at the left one even though i select text on the right one.

2)(i plugged the left one out)As soon as i open a window and click on something in the window the window cannot be moved anymore, and the desktop cannot be selected anymore either (though u still can do something inside the window), as soon as you close the window (if you are lucky and there is a "close" button) the desktop can be used again.

This all started when i played a flash game which froze like everything but the game, and i had to restart the computer. I guess it somehow screwed the .conf file or the xserver. I already tried the xorg.conf.backup but it didn't help!

Ubuntu Multimedia :: [Monitors] Dual Showing As One 3600x1080?

Jul 21, 2011

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.

Ubuntu Multimedia :: Dual Monitors + Compositing - Any Success Stories?

Jun 3, 2010

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?

Ubuntu Multimedia :: Custom Resolution With Dual Monitors In X Server?

Jan 25, 2011

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.

Ubuntu Multimedia :: Setup Dual Monitors With Individual (non-mirrored) Desktops

Dec 17, 2010

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

Ubuntu Multimedia :: Supported Graphics Card For Dual Monitors Setup

Jan 31, 2011

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.

Ubuntu Multimedia :: New Install Killed Dual Monitors - Nvidia Setup Not Working ?

Sep 14, 2010

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:

Ubuntu Multimedia :: Can't Seem To Get Dual Monitor To Work ?

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?

Ubuntu Multimedia :: X11 Segfault With Tri Monitor Dual Gpu

Jul 31, 2011

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

Code:

configuring the ati driver:
