Ubuntu Multimedia :: Make Use Of All 3 Monitors In One Giant Desktop?
Jan 24, 2011
My Kubuntu desktop uses 3x24" monitors running on two NVidia cards. I'm using Xinerama to make use of all 3 monitors in one giant desktop. Trouble is I really miss hardware acceleration which I had before with TwinView.
Is there *any* way to make Xinerama use the hardware like it's supposed to? The way it is, it makes the computer struggle; the i7 with 12 GBs of RAM runs like that 200Mhz MMX IBM Aptiva I had in 1995.

I'm using two monitors with an ATI Radeon X600 card in Ubuntu 9.10. I got the duel monitors to work by running sudo Xorg -configure, but now my desktop effects don't work. How can I get them to work again?

So the first couple of days using Unity with my dual monitors went fine. Today I plugged in my laptop to the second monitor, and while the top bar and the side menu are being displayed, all the desktop icons, background, and actual program windows are black. Basically I just have the menu bar and the launcher. The windows are still there when I unplug the second monitor.

My login screen currently mirrors the image across both of my monitors, which are different sizes, causing one of the two images to be ugly and stretched. After logging in the monitors are configured correctly. Is there a way to either 1) disable one of the monitors during login, or 2) use both monitors without mirroring the image?

I have KDE4 in openSUSE 11.3 on a laptop. And I have this 23" monitor that I can connect to the lappy's VGA socket. So when I'm not travelling I can switch from the lappy monitor to the large monitor.But there are occasions when I want to see 8 or 10 live, dynamic graphs simultaneously.Is there software that will allow me to position the video output across two monitors , horizontally?

I had a dual monitor setup going for a while, then one monitor broke, and I dropped back down to one. In some ways, the computer seems to have noticed this. I have an NVIDIA card and the NVIDIA drivers, and in NVIDIA X Server Settings it shows only one display. I had it configured in the Xinerama fashion, two continuous desktops side by side.
However, my desktop is still drawn as though there are two monitors, the result being that I can only see half. This is easily apparent when I zoom out to the desktop cube. It wouldn't be much of a serious problem, except for some reason, several important applications I use for work are popping up messages on the part of the desktop that I can't access. I installed the latest NVIDIA drivers,driver reset might prompt whatever the problem is to go away (and it's good to do that regularly anyways) but no dice.

I created a bash script which when executed as a desktop application modifies its own application icon. This is done my altering the Icon= line in the application's .desktop file.
Here is a gif of the application in action: [URL] ..... As you can tell, there is an approximately two second delay before the icon changes. I was wondering if there was a way of making the icon change immediately.
For completeness sake here is the script I am using:
Code: Select all#!/bin/bash
LAUNCHER=/home/alessandro/.config/xfce4/panel/launcher-29/14360293821.desktop
PLAY_ICON=media-playback-start-symbolic
PAUSE_ICON=media-playback-pause-symbolic
if [ ! -z $(grep "Icon=$PLAY_ICON" $LAUNCHER) ]; then
sed -i -e "s/Icon=$PLAY_ICON/Icon=$PAUSE_ICON/g" $LAUNCHER
elif [ ! -z $(grep "Icon=$PAUSE_ICON" $LAUNCHER) ]; then
sed -i -e "s/Icon=$PAUSE_ICON/Icon=$PLAY_ICON/g" $LAUNCHER
fi

How can I make a window span over both monitors? I have the monitors configured using the KDE monitor setting tool. I need specifically full-screen (for presentation purposes) or at least a maximized window. Kwin insists on locking the window on one desktop.interestingly it really is Kwin preventing me to do this. If I get rid of KDE and just launch a plain X session, the window maximizes correctly.

I wonder if this is possible/easy/practical to do in Ubuntu: I want to have one computer serve two sets of monitors and inputs in two different (adjacent) rooms. The computer and one monitor will be in my office for desktop use, and a HDMI cable to my TV on the opposite site of the wall (I already have a hole for the cable) will serve HTPC content.
I assume I will need two videocards. But other than that, is this fairly straight forward, or is it difficult?

Recently I've bought this motherboard : [URL] ...
And this graphic card : [URL] ....
Now I have attached two monitors on the computer,the first one (the monitor that is working) is attached to the DVI port of the nvidia graphic card,the second one is attached on the VGA port of the embedded graphic card of the motherboard.
Since I would like to play a little with blender,I need to use two monitors at the same time because in this way I can follow more video tutorials at the same time.
I'm using this version of debian :
Linux ziomario-Z87-HD3 3.2.0-4-amd64 #1 SMP Debian 3.2.60-1+deb7u1 x86_64 GNU/Linux
and this is the informations concerning the graphics card installed on the computer :
root@ziomario-Z87-HD3:/home/ziomario# lspci -nn | grep VGA 00:02.0 VGA compatible controller [0300]: Intel Corporation Haswell Integrated Graphics Controller [8086:0412] (rev 06) 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation Device [10de:11c0] (rev a1)

I experience very poor desktop performance on my system. General clicking responsiveness is poor, taking over second or two to focus to a new window, move windows around, ... etc. The Xorg process constantly uses over 60% of the CPU even when I'm doing nothing, and when I do click around it will quickly go up near 100% usage. Performance is initially OK when I first launch into my Gnome environment, but it soon deteriorates within 30 minutes or so. Eventually, after days of being up and running, my desktop will crash.I am running Ubuntu 10.10 with latest upgrades. I have four monitors attached to my "nVidia Corporation G98 [Quadro NVS 420]" graphics card. I am running the "NVIDIA accelerated graphics driver (version current)" recommended in the Ubuntu "Additional Drivers" app. I get a fair number (hundreds) of these in my /var/log/Xorg.0.log:
Code:
[862923.098] (WW) NVIDIA(2): WAIT (1, 6, 0x8000, 0x0000ba04, 0x0000ba14)
[862923.099] (WW) NVIDIA(3): WAIT (1, 6, 0x8000, 0x0000ac44, 0x0000ac54)
[862923.099] (WW) NVIDIA(0): WAIT (1, 6, 0x8000, 0x0000fca0, 0x0000fcb0)
[code]....
though they don't appear constantly while my desktop is running (I assume they may come in batches?). Not sure if they're relevant. A separate issue, though possibly related, is the SpeedCrunch app (a desktop calculator) is guaranteed to crash my desktop as soon as it gets focus. Here's the relevant output of "lspci -v" which shows my graphics card:
Code:
03:00.0 PCI bridge: nVidia Corporation NF200 PCIe 2.0 switch for Quadro Plex S4 / Tesla S870 / Tesla S1070 / Tesla S2050 (rev a3) (prog-if 00 [Normal decode])

Normally when a program is open an entry is placed on the taskbar in order to easily find it, which is useful when a lot of programs are open. In Ubuntu 10.04, when I moved a program to the other monitor (I'm using 2 monitors) the taskbar entry also moves to the taskbar on that monitor.
Now I switched over to Ultimate Edition, which is Ubuntu 10.04 with a lot of stuff added to it. When I drag a program to the other monitor, the entry in the taskbar disappears, but it does not reappear in the taskbar of the other monitor. So now the only way for me to find a program on this monitor if its hidden behind other windows is to use alt-tab.

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.

Currently I have a perfect setup of 3 monitors,2 GPUs running under Xinerama. I cannot get desktop effects running at Normal or Extra, when I try to enable either one I get the following message "The Composite extension is not available". Without Xinerama it works along with Compiz. I am running Ubuntu 9.04 x64 with a ATI HD4870 and ATI HD4350 GPU. I have the latest ATI display drivers (set up properly to my knowledge). Here is my xorg.conf file.

I recently did a clean install to upgrade to 10.10 and I also got a 2nd monitor recently after upgrading. I want to be able to connect remotely to my desktop like I used to from my phone, but when I connect I get a black screen the size of my full desktop(both monitors) and I can move the mouse/type.

I want to make a live-USB containing among others both Ubuntu desktop i386 and Ubuntu desktop AMD64. How do I go about this? I tried using unetbootin, first adding i386 and then amd64, but that failed. My computer with an athlon II did manage to boot, and showed it had booted into the 64-bit version (ram shown was 3.9 GB, i386 goes to about 2.7 I think), my wife's computer with a pentium 4 did not manage to boot, got to a black screen. I think this is because casper has issues, being overwritten (I'd seen something to that effect somewhere), and thus only the latest version added being booted (in this case amd 64).
I'm under the impression that the startup disc creator included won't help, nor won't the multicd.sh script, so how do I circumvent the issues?

I am running Ubuntu 9.10 on an HP laptop with an Intel 82852/82855 GM/GMC Graphics controller. I have a 2nd monitor attached to the VGA port (HP f1703). The problem is that the two screens have different resolutions. the laptop is 1280 x 768 and the other monitor is 1280 x 1024. The xorg.conf file that was created with Xorg -config set both monitors up with 1280 x 1024 resolution so my screen on the laptop looks all "squashed". I have tried to reconfigure it using the Display Preferences dialog but after i re-boot, both screens are unviewable and I have to restore my previous xorg.conf file. I went through the HOWTO: Jaunty Intel Graphics Performance Guide procedure to setup a "safe" configuration but didn't work and I had to restore my "good' xorg.conf file. What do I need to do to setup my two screens with the correct resolutions: 1280 x 768 and 1280 x 1024?
Here is the video portion from my "good" xorg.conf file
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Monitor Model"
EndSection

Is it possible to run ubuntu with 3 monitors on 2x8400gs? What I have tried: Installed 10.04, enabled latest nvidia drivers. Enabled and arranged each monitor as a separate x window. However, when I did this configuration I couldn't move the programs from the (primary monitor) to the ones plugged to the other 8400gs. What I plan to use ubuntu for:
Mainly work in eclipse, firefox, and evolution. I have no interest in games since this machine is my workstation.

I'm not new to this distro or the forum I only decided to register today seeing as I actually do have a problem and need help because I can't work it out myself. I'm currently trying to get my 3-monitor set-up to work with Natty but I just can't get it to work. I can get 2 of my monitors to work fine in twin-view, and I can move windows between them, but I want to be able to move windows between all three of them. Now, I've tried many different configurations, I've tried making them all Seperate X's, but that didn't work as only two of them turned on and it was like Xorg crashed because Ubuntu would login, but nothing would come up after that it was just like the default Ubuntu wallpaper with no launcher, or desktop or even management. I tried ctrl+alt+f2 to try bring up terminal but that never worked either. i then tried using 2 monitors in twin-view and 1 as a seperate X, but that didn't work either as the same problem happened when I made them seperate X's.

I know it can be done, I just need to know what the hardware is called. There is a community center in the area and I might have a chance to help out. Due to not enough funding the center was only able to get One PC and five monitors. What I hope to be able to do ( and know its possible ) is get the hardware to make each monitor is own terminal with keyboard and mouse.

I liked Unity because I only had to press the super key to get a giant magnifying glass, type what I want, hit enter, and bam get the document/application I was looking for. Basically, no or minimal mouse use is the desire. Since I decided not to stick with Unity, I know there've gotta be apps out there that provide this functionality; I'm just not sure how to find them.

Currently have a Server 2003 fileserver. I am tired of having to buy a whole new hardware array every time I need more online space. I'm up to my 3rd controller/disk swapout in 5 years and I need something truly expandable. This time I am shooting for the stars and devising a system that will have an upper limit of 80TB instead of just doubling or tripling the current space (6TB). The server will initially be equipped with a 4-port eSATA contoller with a single 5-drive tower running through a port multiplier to one of the eSATA ports. As time goes on more towers will be added to fill all the eSATA ports (5 drives per port, 20 drives). If needed a second controller will be added to provide another 20 drives worth of capacity. (40 drives total). I need to work out what the best way to configure these drives is, to have some level of redundancy and also to keep the available data space reasonable. What I've worked out so far is:
LVM - expandable volume, all space should appear as a single volume. Start with an LVM volume over the 5 drive mdadm array. Expand it over new 5-disk towers as they are added.
|
v
MDADM - Each tower of 5 disks will be in a 5-disk RAID5 array set up with mdadm. As new towers are added the md* device will be used as new space to expand onto with LVM
Here's a quick diagram to show what i mean [URL]. So what I haven't been able to find out so far is:
> Is this really a good idea, what other way is there to get truly expandable storage?
> What happens to the linux kernel when it reaches /dev/sdz?
> Is mdadm capable of managing 40 disks, even if they are grouped as different arrays?
> Can LVM create a 57.92TiB volume?
> What FS would I need to use to support a 57.92TiB volume?
> If one md* fails entirely (2 dead drives from a group of 5), would anything on lvm0 be recoverable?

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.

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
