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?

Not sure if this is right place or not but i'm looking for some success stories of Cheese and external webcams or built in netbook cameras. Would love to see some actual examples.
Here is the type of behavior I seem to always* get:[URL].. *I have tried 3 different computers, dell 8100 (1.5 ghz p4, 256 ram), ibm thinkcentre (1.4ghz p4, 512 ram), ibm thinkpad t42 (1.7ghz p3, 1gb ram) and several different webcams (2 old logitech cameras, ps3eye, ms lifecam show) running either fedora or ubuntu.
see also this post for some other movies of a system i had similar problems with:[URL].. here is a list of cams that work with skype but i find skype and cheese to be different as it's the RECORD feature that seems to cause the problems. displaying the feed is never too bad, but recording seems to break the feed. [URL].. So i'm looking to know if anybody out there has had success with cheese or another webcam RECORDING program on linux. i'm working on several videobooth [URL]... and would love to permanently ditch my mac for linux but having trouble finding acceptable performance in this area.

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.

I am using Ubuntu 11.04 - the Natty Narwhal 64-bit and I am using the Nvidia Xserver version 173.14.30 and it never has any problems when I am in single monitor mode but when I turn on twinview mode like this----
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

Just installed a clean version of 10.04 onto my Sony VAIO with an ATI Radeon Mobility x700 video card.Whilst using 9.10 KK I was getting low resolution but the dual monitors worked totally fine.Which I use to connect to my TV via a RGB/PC Cord.Since upgrading to 10.04 the resolution is awesome BUT when I merge both monitors the laptop goes mental and shows a white/whitish screen.If I use have both monitors side by side its OK but then I cant run xbmc to show movies. I'm stuck with making the TV my main monitor, which is a pain.Why is the laptop going white after merging screens? Does anybody have any ideas?

Anyone want to take the time to help me get my ATI x16XX to work with dual monitors?I'm really tired and frustrated after upgrading to lucid and having the "vendor" drivers stop working.I can get a screen up, but cannot get the free driver to recognize the fact that I have two monitors.I tried renaming my xorg.conf and rebooting, but that caused my system to stop at startup.

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.

I'm building a new Ubuntu system for use as a desktop machine and personal server (http, smb, smtp). It'll be based on an Intel i7 950 and a Gigabyte X58A-UD3R LGA 1366 ATX Motherboard.
I'm looking for recommendations for a graphics card that will support dual monitors and runs well under Ubuntu. Would like some decent 3D support.

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.

I am running 9.10 on a laptop with an external monitor. when i run a flash video in full screen on the external monitor and click anything on the workspace of the laptop screen, the flash video on the external monitor will revert back from full screen.
this did not happen a couple of weeks back. i have not used it for 3 weeks. maybe one of the updates in between changed some setting?
does anyone now how to fix the problem?

I have searched the web read every post and still i cant seem to get dual monitors working correctly. I have a notebook and a extra external screen at home. Here is my issues
1) My Desktop background stretches over both screens.
2) My Display seems to think I have dual monitors attached permanently.
3) fn + F4 only blacks out screen for a few second.
get this sorted so that when I plug-in the external monitor it works and when I unplug and reboot it goes back to one screen

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

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.

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'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:

Dual Boot Gone Bad I have been trying to set up a dual boot laptop on an old Dell Inspiron 2600. I got the machine cheap, and it is in excellent condition. I have upgraded the Bios to A11 (it was A4 when I got it) and put in a 40 Gig HD. It is maxed-out in memory at 360 Mb. It has the awful (by today's standards) Intel i810 video mess. I created an NTFS (primary) partition on the first half of the drive and installed XP, updated through SP3. I then attempted to install Debian 6 (squeeze) on the second half. I was unable to get anywhere with an installation using a squeeze Live CD. The screen just goes blank about 60 seconds into the installation, and everything freezes up. In rescue mode, I can get some screen play, but the rendering is awful and half of what you do is actually off the screen and you can't see what it is you are doing.
I hooked up a separate monitor, and was able to watch the installation just fine until it reached a certain point in the boot-up, then everything again went blank and the machine again froze up. I tried Ubuntu 10.10, Ubuntu 10.04 LTS, Mint 10, and Ultimate Edition 10.10 with varying degrees of success, but none completing and working.
The Ubuntu 10.04 LTS actually installed, but I could not get sufficient graphics in either a terminal (entered at the end of the install process just before re-booting) or booting to text only mode to sudo a change to the xorg.conf file that was native to the system, rather than to the installation package itself (which goes away when you reboot).
I was able to install 'squeeze' using the 'expert graphical install' mode under 'advanced options' (it lets you select a screen resolution when it starts the install), and when I got to the end of the installation, before re-booting, I told the system to open a monitor as 'root', and wrote what I thought would have been an appropriate xorg.conf file in the /etc/X11 subdirectory using nano (monitor and driver specs, as well as suggested xorg.conf entries obtained elsewhere on the web).
[Code]...
I'M SO CLOSE! Can somebody help me and tell me how to edit GRUB so it again recognizes the partition... or reinstall GRUB.... or let me know if the problem is with the XP MBR.... And if so, maybe hopefully lead me to how to fix THAT issue without screwing up the Debian install (I know this isn't an "UGH"- Windows forum). If worst come to worst, I can delete all the Linux partitions, use my Windows install disk to repair the MBR, and reinstall lenny.... Hopefully with GRUB not losing XP this time. I hate to do it because it has taken me a couple of days to get ANY form of Linux actually working right on this machine..... but at least I know how to do it now and what distro will actually work.
Also, anybody with a clue as to why squeeze won't boot after what appears to be a successful installation (with the above-listed xorg.conf file in place) and what I can do to fix that issue would also be appreciated. It will be nice to have a system installed that has current support next year.

I have a Dell inspiron 1525 laptop with a 1280x800 display and an external 1280x1024 monitor. I'm using 9.04 with openbox. I've done a loooot of online reading about how to get a dual monitor setup using xrandr, and I really don't know what I'm missing here. So here's the deal: I want to have my external monitor on the left of the laptop's display, and of course I want each of them to display different parts of the desktop.
First I set up the right resolution to each one of them (I do it using lxrandr). Typing xrandr -q in a terminal, I get the following:

I have an asus p5kpl-cm MB. I plugged in a radeon 9200 pci card. In the bios, I can set up:
pci/igd
igd/pci
igd
etc.
This determines which of the 2 displays (pci card or internal graphics on the MB) is the boot display. That determines which comes up with the bios screen and then once booted into ubuntu (10.04), this is the only adapter/monitor seen. The button detect monitors doesn't do anything.
lspci sees both my internal and pci card graphics. So, I can get either to work just fine (auto detected etc.) just not both at the same time.
I've tried all of the 3 above settings, and even when I set it to just igd, lspci still sees both my adapters. It identifies them correctly, and it works perfectly, detecting the monitor and knows the resolutions for each - just not both at the same time.
Does ubuntu know how to automatically configure more than one display w/o doing something else, or must I do something else to get both going together?
Code:
$ lspci
00:00.0 Host bridge: Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller (rev 10)
00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 10)

For the past 4 days Ive been trying to install ubuntu 10.10 64bit with no success. I am a total newbee when it comes to linux so I will be needing your kind help with it.At first I installed ubuntu to one of my portable drives with no problems, but now I want to install it to my hard drive and have a dual boot between windows XP and Ubuntu.
When I arrive to the manual partitioning part is where I get lost. I have totally destroyed my windows installation 5 times already ( thank god for norton ghost for restoring my windows installation. )
I have read several articles and blog posts regarding a dual boot system with windows and Ubuntu but none of them cover my specific situation so I keep getting lost and screwing things up.

I'm having trouble setting up dual monitors on my HP Pavilion dv7-1020us laptop, with an Nvidia 9600M GT graphics card, and Ubuntu 9.10. I installed Ubuntu via Wubi, on top of Windows 7. I tried this before on the same laptop when I was using Vista and Wubi, and Ubuntu was able to recognize my Graphics card, and install a proprietary driver. I wasn't able to test dual monitors, though. However, now that I'm using W7 and Ubuntu, it cannot use a dual-monitors correctly. It recognizes the monitor, but it only displays a mirror display of my Laptop monitor, not acting as a separate monitor, like I want it to. I tried messing around with the settings in the display menu, but nothing works. I tried downloading linux drivers for my card from Nvidia's site, but the file is in a .run extension, which I don't know how to install. What should I do to get this working?

I have a ATI VisionTek 9250 128mb DMS59 PCI video card that I would like to use for dual monitors on Ubuntu 10.04 Gnome. I installed the card and booted the live cd. Both monitors are recognized when I go to the display settings, but when I un-check the mirror box, nothing changes. I am still only getting one monitor. I was previously using 9.10 and it sometimes worked, but not always.

I have a brand new installation of Ubuntu 10.10. I'm using a GeForce 8600GT graphics chipset. I have two monitors, and my goal here is to have them both working under Ubuntu in their full resolutions, and I've not had any luck with this yet. I've got a Viewsonic VE155s with a native resolution of 1024x768, and a Chimei CMV 221D with a native resolution of 1680x1050. When I first installed Ubuntu, both monitors were working, and the VE155s was working in its native resolution of 1024x768, but the CMV221D was stuck in 640x480.
The Nvidia video configuration utility was not identifying the latter monitor - it only reported it as DFP-0, and doesn't allow any resolution above 640x480 to be set. The mechanism (which has a name which I don't recall) which allows the OS to interrogate the monitor's firmware to find out the monitor manufacturer, model and accepted resolutions and frequencies to use does not seem to have worked. (I previously had the Nvidia driver installed, but I've since switched back to the default open source vesa driver. I won't use the closed Nvidia driver if I don't need to, but if I need to use it to get acceptable performance from this hardware than I will.)
So I did a little bit of reading and I did some hacking of xorg.conf. Previously I had the 15" monitor working in 1024x768 and the 22"
monitor working in 640x480. Now I've got the 22" monitor working in 1680x1050 as desired, and the 15" monitor not working at all. Here's a copy of my xorg.conf. For the sake of brevity I have not included the unnecessary bits such as input devices.
Code:
Section "Device"
Identifier "NVidia"
#Driver "nvidia"

I'm trying to set up my monitor and tv for dual display but I'm having some problems. I want them to display the same thing so I've enabled twinview and I figured the second display position should be set as clone but when I save xorg and restart the x server the position reverts to absolute. Anyway, the monitor is set as the primary display and it's the one I'm having problems with. The tv is fine but the monitor's display is stretched off the screen so I can't see the far right or bottom of the screen. I'm very new to linux and I'm just finding my feet so if there's any other info needed you'll probably have to be very specific.

I have a laptop with the radeon HD 5650 video card. I used ubuntu's hardware drivers program to install the official drivers, and it seems to be working well, including 3D acceleration in games. However, it seems that enabling compositing in KDE makes it much slower. For example, running glxgears without compositing gives me about 35000 frames in 5 seconds, after I enable compositing it's only 6000 frames. But it's not just glxgears, the slowness is very noticeable in games as well.
On my old computer, I had an nVidia card, and enabling compositing in KDE made it a little slower, but the difference definitely wasn't that huge. o_O Is it some wrong configuration, a bug in ATI's drivers, or something else?

I just ran one of my weekly upgrades last night (I'm using sid with the 2.6.32-5-686-bigmem kernel). Now compositing no longer works with kde (4.4.5). When I click "resume compositing," I get a message saying "Compositing has been suspended by another application." I'm using the radeon driver. My middle mouse button also stopped working after the upgrade, i.e., I can't use it to copy and paste; can't open new tabs in any browser using the middle button. (The mouse works perfectly in my other two computers, both of which still have kde 3.5.10 installed.) None of these problems existed before last night's full-upgrade, so the upgrade definitely broke a few things, and I don't know how to fix them.
glxinfo | grep render says direct rendering is working. But when I run glxgears, I only get text output, without the animated gears. The results from 'glxinfo | grep -i opengl' say "OpenGL renderer string: Gallium 0.4 on AMD RS880.", and Im guessing that Gallium is causing my compositing problem. Would this also explain why the middle click on my mouse no longer works? Does anyone know how I can get compositing working again, and my mouse?
