General :: How To Fullscreen Application Across Both Monitors Of Dual Head Display
Feb 3, 2011
I have two Ubuntu 10.4 machines (and Ubuntu continues to hide more and more xorg.conf config such that I no longer know where to find it). One is a laptop running dual headed - DP1 is the internal screen, and VGA1 is an external monitor; both are running at 1600x900. The other machine is a desktop running both VGA1 and HDMI1 (which is actually a display port with a DVI adapter) at 1600x900. So in both instances my desktop is 3200x900. I run a VNC server on the laptop and connect to it (via SSH tunnel) from the desktop - when I press the full screen hot key, I get a 1600x900 view of the remote machine on one monitor, and half of my local desktop on the other monitor - the "full screen" only expands to fill one local monitor.
Normally this is exactly what you want when you full screen a web browser, email client, or other application. I'm sure there's some X magic to make it clear what a full screen actually entails, and the vnc client application is just dutifully accepting what it's told. While I would like to keep the normal full screen behavior for regular applications, but when I'm VNCing to another 3200x900 machine, I'd really like full screen to stretch across both local displays. Resizing the window to be "close" isn't quite good enough since I still have local panels at the top and bottom of one display (though I can set them to autohide), plus the VNC client application window border (since it doesn't appear to respect -notitle).
Is there any good way to have X lie to a single application about the "full screen" size? Can I get it to lie to all applications? xrandr --noprimary appears to have no effect.

I'm using gnome in a dual-head setup with individual desktops. Is there any way to "jump" to another monitor using the keyboard only? Now the only method I know is to move the mouse pointer to the another screen and click on something there. Can I do something like that without using the mouse?

I have an Nvidia card that supports two monitors. Actually I have it setup. The problem I am having is I want to turn one of my monitors sideways so I can read forms easier. I can do this with just one monitor. RandR works fine with that. But it seems that when the system makes the two monitors into one long one it will not allow me to tweak the rotation in RandR.
Is there something I am missing. I deal with a lot of contracts and forms. And when I am reading them I hate scrolling. So I thought this could be an option. I have searched the net for 6 hours now. Maybe I do not know what I should be searching for.

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.

I just installed lucid on my laptop with a second screen. Unfortunately, I cannot display any video. Neither on the laptop screen nor on the second external screen. In contrast, rebooting without attaching the external screen allows me to display videos again.
I never experienced this kind of behavior with Ubuntu 9.10.
Graphic card: Intel 945
Let me know if you need further information.

When I try to run the 'system-config-display' program for Fedora 11 and I use the dual head tab, attempting to save the settings results in this:

And it won't save the data.

I want to be able to change the settings for my top down dual head display. Basically one monitor sits on top of another right now. How it was setup before was that they used to sit right next to each other so when you mouse over to the right it would go to the new screen. The problem is now when one sits on top of the other I want to be able to just mouse up instead of mousing over to the right. I don't want to use the gui to be able to do this. I want to find out what config file and specifically what setting in the config file would allow me to change this.

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.

How do i fullscreen wow across two monitors in ubuntu? I am running ubuntu 10.04 with two 1024x768 lcd monitors running from a Nvidia 9800gt graphics card running in twinview. I ant to maximixe WoW(World of Warcraft)(running under wine) as fullscreen across both screens. The WoW client recognizes a resolution option of 2048x768, but when i apply it, it squeezes it onto one monitor. how to fullscreen across both?
And i have removed the touching sides of the monitor cases so the screens touch directly so it is feasible to play.
also, i am using the latest nvidia drivers

which will show a png from GIMP on the screen in fullscreen mode. I was using GIMP and there is an option to save my image as an .h or .c file. I tried .h and it saves it as some kind of very large variable. I want to call this from my own C program and display it on the screen.

I am attempting to get a Dual Monitor Display using aticonfig (and/or manual editing my xorg.conf file). My graphics card (a Radeon HD 4350 with latest ati drivers ) has only a single output but I am using a splitter cable to connect it to two monitors.
I am want one monitor to be 1600x1200 and the second monitor to be 800x600.
This is the command I had tried to no avail.
aticonfig -fq --initial --dtop=horizontal,reverse --resolution=0,1600x1200,1280x1024,1024x768 --mode2=800x600
What am I missing? Should I be using this configuration utility? Or should I be trying to manual edit my xorg.config? All the information I have been able to find seems specific to Dual Head Displays.
EDIT: It occurs to me to post my edited xorg.conf file

I'm running a fullscreen display app which shows a 3D scene in OpenGL. The app runs continiously throughout the day unattended.
Here's the sequence of events in how it's loaded:
1) The computer is turned on, and boots into F11 (x86_64)
2) A non-privileged user is automatically logged on
3) The gnome startup applications list contains an entry for a loading script
4) The loading script waits for the network interface (eth0) to ccome up, then starts the display program
This all works just fine, except that about 30 minutes after the computer is turned on and the app starts running, the screen blanks out. Attaching a mouse to the system and moving it around a bit brings the screen back to life. Likewise, SSHing into the machine and killing / restarting the application works as well. Once either of these fixes has been performed, it runs flawlessly for the rest of the day.
I have turned off the screen saver, and set the power settings for monitor shutdown to 'never'.

I installed the latest nVidia drivers on my laptop using the 9800M card. The laptop is a Gateway P-7805u and I'm connected to the second monitor using VGA.Also, before installing the nVidia drivers (and just using the basic drivers included with Kubuntu 10.04), basic dual monitor support worked, except I could not enable compositing features for some reason. So I thought the proprietary drivers would fix this.Several issues have arisen since installation:
1) I've clicked through all of the display settings to activate the second screen with absolutely no change.
2) When I try to apply settings and Save Configuration as the nVidia help suggests, I am told that I cannot save to the X.conf file. I assume this is due to innate permissions on my user settings, which I have no idea how to properly configure.
3) I have no idea where to go from here, as most of the fixes I found online involve Linux syntax and verbiage, to which I'm totally clueless after spending over half my life with Windows.

I frequently watch movies on my computer, but I have two screens. So having something displayed on the other monitor is annoying.
I currently use this to turn off my monitors:
xset dpms force off
I was wondering if there's any way to turn off monitors independently, without having to physically press a button on the monitor, of course.
A program that tells the other monitor to display nothing but black would suffice, but I'd really prefer not to waste the power.
I also have Nvidia TwinView, so applications like grandr aren't aware of both monitors as being independent.

I, too, have a dual-monitor set up. I would like to use one monitor to run X11, and the other to run a text-only mode, like when you press ctrl+alt+fX, where 1 <= X <= 6.

I am looking to build a new desktop. What is the lowest end video card that will fits the following:
Supports 2 monitors at 1920x1200 or 1600x1200
Works with Linux.
3d performance isn't much of an issue, since I don't play computer games. I use the computer mostly for programming, which is why I like having the large resolution, so I don't have to scroll around so much.

In Synergy, is it possible to set up your config so that you have one server and one client, both with dual monitors, but the client machine has its monitors such that one is on the left of the server's left monitor, and the other is on the right of the server's right monitor? For example:
+----------+ +----------+ +----------+ +----------+
| client | | server | | server | | client |
| screen1 | | screen1 | | screen2 | | screen2 |
+----------+ +----------+ +----------+ +----------+
Hopefully my ASCII is good enough to understand. Both machines will be running Linux. If there's a way to do it by messing with xorg configs that would be perfectly acceptable too.

I'm trying to configure Debian to have a spanning desktop with two monitors. One is VGA, and the other is Display Port. They are both with the video hardware on the motherboard, an Intel 4 Series Chipset Graphics Controller. This is the output I get when I do a query on xrandr:
Code:
Screen 0: minimum 640 x 480, current 1600 x 1200, maximum 1600 x 1200

I'm looking for virtual machine software that supports dual monitors on a Linux guest with a Windows 7 host.VirtualBox supports dual monitors only for Windows guests. VMware Player was extremely slow, so I gave up. I'm not sure it supports dual monitors, anyway. Can anyone recommend a product for what I want to do?

My Dell Precision Workstation was shipped in 2003 with RH Linux installed (most likely RHEL 4) - though not sure.
At the time, the dual monitors worked by replacing the X86config file with one sent from Dell.
Since, my disk failed and I had to replace the disk and reinstall RH Linux with the shipped disks, RHEL 5.
Now, I can not find X86config; rather, I have been trying to update the Xorg.conf file with no to limited success.
Both monitors are driven off of one Nvidia Quadro FX 1300 videocard. My goal is to get the screen to span both.
Does anyone have a Xorg.conf file that would support this?

ll the time for me and when they do, I can't do anything.The typical case for me:Trying to run something, application hangs.The screen is either black or an image of the previous used app (aka not responding).This is when i try all sorts of key-combinations to get out of it to either get to a console or some other way to shut the crashed application down, but since the application is crashed and all the keys are overrided (either that or not responding), I cant do anything.Things I've tried pressing:
ctrl+alt+delete (you never know if something useful will happend (: )
ctrl+alt+f1 (I actually thought this would work, but no)
alt+tab (this was my second hope!)

I've just performed a fresh installation of openSUSE 11.3. System specs include GA-MA790X-DS4, PhenomII X4 940 AM2+, Sapphire RadeonHD 3670, two monitors. What I'm trying to accomplish is to set up my KDE desktop to (as it did under 11.2) use a multi-desktop multi-output non-cloned setup, so that I can use my two monitors side by side and maximize windows in either one respectively, etc.
So here I am with my newly installed system. Obviously I can't use fglrx, as it doesn't yet support the 2.6.34 kernel, so amdcccle is right out. SaX2, I notice, is gone. I have tried using KDE's built-in configuration tools, but the dual-head setup doesn't persist between logins. Strangely, windows that were open on the second monitor do vanish off-screen, but the monitors return to their overlapped positions so it's useless. Monitor 2 doesn't even retain its resolution setting. As one does, I decided I'd manually edit the X configuration file. SHOCK HORROR! No xorg.conf So what I'm driving at is this: How oh how do I configure my X.org to remember that it has two, quite different, monitors under openSUSE 11.3 ? Sorry if this post is hard to follow, I got very little sleep while trying to sort out the myriad problems I caused myself in upgrading.

I'm building another desktop. This is not a gaming system (though some video does cross my path), it's primary focus is as an application development platform. The thing is based on a SuperMicro two CPU motherboard with a couple intel multi-cores, 16GB RAM, a hardware RAID, and CentOS 5.6 (64bit). To this mix I would like to add a solid dual-head graphics card. Something that will support a couple HP LP2465 monitors (not new but functioning well). Speed of rendering is not my biggest concern, stability and "real estate" (the monitors are 1920x1200 and I want all of it).
I've looked a little at the Matrox items and started researching nVidia, but would like to hear opinions from those "in the know".The motherboard, though a solid performer, may have just made this trip unnecessary. It has a quirk that I hadn't considered before. It has several PCI-X slots (64-bit @ 133MHz) but only one "PCI-Express 1 (x8) on a (x16) slot". Does that seem a little strange to anyone else? Not that there is just one PCI-E but that it will fit a x16 board but will only support x8 connections...

In this particular example I am using NoMachine's NX, although the behaviour also occurs when running VNC for instance. I'd like to connect from my laptop (1 physical screen), to my desktop at work (2 physical screen) via NX. It all works but the following problem occurs: When I connect with my laptop to my desktop I (almost) always am connected to the 2nd physical screen, whereas all windows appear on this first screen. I can interact with my desktop, use the task manager etc, see which windows are running, but any application I start, starts on the first screen (which I cannot see) and for the life of me I cannot move them from screen1 to screen2 without dragging them (which obviously is impossible since I only see screen2).The obvious workaround is: *before* you connect disable the second screen via the display manager but for me this is a non-pratical work around because it requires a lot of actions before heading home. how I can connect from a single-head desktop to a dual-head desktop without crippeling my desktop experience?

I am trying out conky for the first time and rather enjoying it. I have a small frustration though. I have a dual head setup and would like to have identical conky's showing on both monitors. I have tried creating two .conkyrc's (.conkyrc1 & .conkyrc2) and then using:-
Code:
$ conky -c config1
$ conky -c config2
to launch them, this results in only one of the two conky's displaying. I did at first think that maybe they were on top of eachother, but one conkyrc is set bottom_left, the other bottom_right so they should not be right??
When I try to run them as above terminal shows:-
Code:
gregg@burt:~$ conky -c config1
Conky: invalid configuration file 'config1'
Conky: invalid num arg for top. Must be between 1 and 10.
Conky: invalid num arg for top. Must be between 1 and 10.
