Ubuntu Multimedia :: Multi Monitor Configuration With Two ATI GPU
Aug 20, 2010
I have 2 GPUs in my system, a HD4870 and a HD4350. The HD4870 has a Benq 24" and a Dell 17" which are working fine in a multi-display desktop setting (No Xinerama) configured via CCC. On the HD4350 I have a single Samsung 17" which in CCC is listed as '[Unknown Display] Unknown adapter' and cannot be used. How can I get that working properly so I can configure it as an additional screen in this setup?
Code:
Section "ServerLayout"
Identifier "aticonfig Layout"
Screen 0 "aticonfig-Screen[0]-0" 0 0
EndSection
Section "Files"
EndSection
Section "Module"
EndSection
Section "ServerFlags"
Option "Xinerama" "off"
EndSection .....
I have tried a few different configurations in Xorg but I don't have a great understanding of the configuration files so I have broken it a few times. I have read through this guide [URL]. It's a guide based on the work around for multiple Nvidia GPUs with a six monitor configuration while still being able to run visual effects without a hitch. But I didn't continue after reading "If you're prepared to use ATI cards, and therefore deal with their drivers, a better option might be to buy an Eyefinity card." Since that is based on the drivers back then I figure maybe it's possible with ATI drivers now. I'm sticking to Ubuntu this time around there is no doubt there so I would really like to get my third monitor working.

I am running a multi monitor setup with xinerama, and everything works great except when I try to play an FPS such as OpenArena. The mouse doesn't work, it gets stuck to the screen edge.

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.
xorg.conf
Code:
harry@ubuntu:~$ cat /etc/X11/x
xinit/ xkb/ xorg.conf xorg.conf.backup
harry@ubuntu:~$ cat /etc/X11/xorg.conf
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 1.0 (buildd@palmer) Sun Feb 1 20:21:04 UTC 2009

I have two monitors of different resolutions. Under settings->display the settings for my monitor look like this: [URL]. Ultimately what I want is to set up this kind of configuration: [URL]. But whenever I do, it doesn't work out. When I up after setting the above settings, my configuration ends up like this: [URL]. Any attempt to change the resolution or to change the display type to anything other then clone is simply ignored. If I disable the second monitor I can set my first to the proper resolution. If I try to set the settings to what I want they will stick but the second monitor doesn't actually turn on, and if i try to drag windows that direction it acts like a single display.
I have tried using the ATI control panel to adjust my display, but there seems to be a problem entering it as an administrator.I can load the CCC just fine as a regular user, but when I try as an admin a terminal pops up, I type in my password, and nothing happens. I want to avoid trying to reinstall my display drivers or do anything drastic. In previous versions of linux I would just nano the Xorg.conf file and be done with it, but it seems ubuntu 10.04 LTS doesn't use Xorg, or at least not a Xorg.conf I am used to. I want to set the monitors at their native res and as independent displays, similar to what twin view did for me not to long ago.

I am trying to set up dual monitors for lenny but nosuccess for the moment.
They were working fine for the same setup on ubuntu.
Using xrandr I get:
I read that virtual screen size could be the maximum part which is of no use in comparison to the current size.
So setting a virtual part in my xorg does not help much. If the above is right.
I have:

I've been using my laptop with an external LCD monitor attached to it at work (Philips 201E). And at home with a different external monitor (Samsung 2032BW). I have an ATI graphics card (HD3450), with Ati Catalyst drivers enabled and I'm using the Single display desktop (Multi-Desktop) seeting. At work I have the external monitor on the left and laptop on the right, while at home the other way around. So when I switch between the two setups, I just needed to go to Ati Catalyst Control Center, change the order of the displays, change the resolution (Home - 1680x1050, Work - 1440x900), reboot and it was all fine.
But since a while it doesn't work properly anymore:
At home it *still* works fine. At work it doesn't work. Sometimes it works for some reason, after a few resolution/setting changes in ACCC and reboots... it's very strange and annoying. Does anyone have any idea for fixing it? I've uninstalled and reinstalled the ATI restricted drivers and that seemed to make it work initially, but it still works just sometimes. This is my xorg.conf currently:
Code:
Section "ServerLayout"
Identifier "amdcccle Layout"
Screen 0 "amdcccle-Screen[6]-0" 0 0
Screen "amdcccle-Screen[6]-1" 1280 0
EndSection

I have a dual monitor setup with a nVidia 7300 card. I'm not sure exactly when this started to happen, but it's happened for a couple of years at least. when I'm in one or the other monitor the cursor will sometimes "stick" in that monitor and refuse to go to the other monitor. it'll just 'wrap around' as when I go to the right part of the monitor, it'll then jump to the left side, and vice versa. Also once in awhile, if I'm in one monitor, the cursor will be taken away and put on the other monitor. I'm just now starting to see a few patterns on what's happening. It's worse if I have VCL playing in the left monitor, (my secondary), and I've got a program maximized in the right (primary) monitor. That's when it'll 'stick' on the right monitor. After I roll up the program or minimize it, then it'll free the mouse. But it's not instant. After it's freed, it still doesn't work exactly. If you click on any program on the left monitor, then you have to move back and forth before the mouse will work on the left monitor.
The second problem I'm having happens only on the secondary monitor. At times the precision is WAY off. For example, if I try to put the mouse right on an icon, and click it. It won't work. But if I move the mouse over to the right or left, suddenly the pop-up comment box pops up, the icon is highlighted and clicking will run the program. It can be off as much as 100 pixels! I've seen these problems in all sorts of GUIs; XFCE, DXCE, KDE 3.x (I never tried it in KDE 4.x since it was nearly unusable) and Gnome. Right now I've only see this on Ubuntu 8.04.01, to 9.10 (I never went past 9.10), and at first I thought it was X since all GUIs had problems. But someone now says that nVidia's driver might be to blame. If you can tell me what command to type in at the terminal, I can supply the current video driver's version.

I have just bought 2 monitors to be used as a x3 multi setup and 2 graphics cards the same make and model (ATI Sapphire Radeon HD5450). This all works in Windows 7 but I have just booted into Ubuntu and removed the old nVidia drivers and got the supported driver. The problem is only 2 monitors are detected as it would seem that it's only picking up 1 card.

I have not checked for a while but did, before posting this, do a search for multi monitor support with KDE 4.4.4 and found nothing.
From what I understand 11.3 is out sometime next month and KDE 4.4.4 is the KDE environment that will be released with that iteration of SUSe.
About a month ago I read about a number of problems with multiple monitor support under 4.4.4. Primarily these issues seemed to be with no more than 2 monitors. The SUSe 11.2 machine here uses KDE 4.3 runs three monitors (Intel core quad, pair of NVidia PCIe graphics cards). I was wondering whether any of the bugs with this type of configuration have been resolved. From what I understood 4.4.4 worked with problems using Twinview but I was not able to find anything that addressed the configuration of having separate X Screens.

With the work monitor on the external LCD monitor I just see "No video input" until I get to the login screen, then it shows up there as well. But after login it will either:

I have asked about this issue before to no avail but since then I have been able to narrow down the main cause of the crashes. My setup:
HD5770 - Running 2 19" LCD's
HD3300 onboard Running 1 47" lcd
Whenever I am in firefox and have pictures open in the browser and move the mouse to the other 19" monitor it crashes, not everytime but often enough to be annoying. Sometimes when it crashes the screen goes blank and I wind up at the login screen, other times it just goes blank and stays blank.

Im running 11.2-64 with the stock KDE (3.5) included with the distro. Recently I messed about attempting an update of Amarok and phonon to get the graphic EQ back for music playback. The "messing about" was not with the one click install offered on the KDE website for 4.4.2.....and interestingly the messing about was the day before they "released" 4.4.2-- with the result that I ended up. trashing" the system and having to reload (didnt loose /home tho another reason why I love SUSe....)anyway I ve been looking around and have seen problems mentioned on the KDE forum with multi monitors in their 4.x desktop environment....it is tempting to "just push the button" on the 4.4.2 install and see what happens but Im not sure I want to spend another few hours here repairing things where I have my workspace back.
This machine is used in my home office, a core quad with 2 GB of RAM, Intel motherboard and a pair of NVidia GT 8500 PCIe cards running 3 monitors..... am curious if anyone is using 4.4.2 in a multi monitor environment, how the upgrade went and any problems with X server with the new environment?

Many people have multi-core cpus supporting frequency scaling now, if you want to see if the workload is being evenly distributed then add as many CPU Frequency Scaling Monitor applets to the Gnome panel as you have cores/cpus. Then right-click each one and select preferences and choose which cpu to monitor.
Now compile a large program or run a cpu intensive game and watch how the workload dances around between the two (hopefully)
Some clever apps like gnome chess will multi-thread and make max use of both cores, sadly many others won't.

I use a Dell advanced port replicator at home and in the office. Each is connected to a second monitor. In neither place does the monitor actually receive a signal even though the monitor seems to be detected correctly in display settings. The function-F8 key does not have any visible effect.
Oh, almost forgot. At work once when I preparing to shut down the second monitor popped on for a few seconds though it was at the wrong resolution.

I have successfully configured my system for a multi-seat setup using 2 nvidia cards in Linux Mint 10 and it works great except for a few things that I can't seem to get to work.
1: I can't access any other drives other than the file system drive. All usb flash drives and even esata external hard drives. When I try to mount, it gives me an error: Unable to Mount <drive>, Not Authorized.
2: If not logged into for a while, the second seat (the one on my tv) seems to "go away". I just get no signal on my tv. I have a hunch that this might be the power saver options turning off the display. I think it does it after an hour or so. [EDIT]: just tried to move the mouse and click the keyboard on the no signal screen, it worked!

I recently upgrade my grub to grub2 and had problem to boot debian. After trying to fix it myself, I played around with grub-image-ntldr, my debian now works ok, but I cant boot my XP anymore.
Now when I try to boot XP, I got "No grldr" message. If I copy my ntldr and rename it to grldr, my XP will boot ok. So it seems that when I try to boot XP it doesn't chainload ntldr anymore, it is looking for grldr.
I tried to change "chainload +1" to "chainload /ntldr", it complains about invalid signature. Does anyone knows why my grub now using grldr instead of ntldr?

i created a second instance of postfix.It isn' t the first time that i made this procedure but with debian i had a lot of problem.I think that the problem is chroot configuration of postfix .In the first i had two problem smtp “fatal: unknown service: smtp/tcp” and the second instance was enable to make nslookup of domain.I copied the necessary file in /var/spool/postfix-second-instace and i solved the errors.Now the problem is that there aren't error in log file but connect to xxx.xxx.net[yyy.nn.yyy.yyy]:25: Connection timed out for all connection. and the email are all in defer directory and the second instance doesn' t send emails.

Currently I have two 1920x1080 screens running in Twinview on my Geforce 275 graphics card. Want I want to do is a quick simple way of disabling my secondary monitor when playing video games or using xbmc to watch movies, etc. I've tried a few applets but they require the xandr function which I think Nvidia doesn't support.
Is there a way to disable this quickly other than loading up nvidia-settings and disabling the monitor everytime. I don't really want to use two seperate x sessions and xinerama due to the fact you can't use compositing.

I have an ATI Radeon HD 3300 on-board video chipset, and an ATI Radeon HD 4350 PCI card. What I want is to have both displays available from one mouse/keyboard. I want to play media on one and have the other as my main desktop.The problem is that with Xinerama enabled, KDE desktop effects do not work (KDE says XComposite and XDamage are not available, even though I explicitly enabled them as extensions in the xorg.conf file), and performance is quite bad. Without Xinerama enabled, performance is great, desktop effects work great, but there's a lot of trouble with full-screen video, and the KWin window manager does not apply in the second display (although I can run a second instance of KWin on :0.1).

Now that Ubuntu 10.04 has multi-touch capabilities built-in, if I do not have a multi-touch screen or surface device, can I get 2 USB mice and get 2 pointers on the screen? One for the right hand and one for the left hand as I am ambidextrous, and would find it very convenient to have 2 mice.

Anyone successfully using VNC client on a Mac to control a Debian server?I have the vncserver setup on the Debian machine properly. But I'm having problems connecting to it from both a PowerMac running Tiger and a MacBookPro running leopard.I can connect no problem from a machine running Slack12.2, have not setup port forwarding on my router to connect remotely yet.My Debian machine is running the latest stable release of squeeze with KDE4.I originally tried this with RealVNC Enterprise for OSX but I'm not gonna buy it so I need another alternative after the 30 day trial ends as they have no free version for OSX.
The situation is that I do freelance graphic design on the PowerMac with Cinema4D and Photoshop so I spend most of my time on that machine which is located in my home studio in my attic. Aside from the MacBook and a Dell desktop(family machine)all my other machines and network hardware are in the basement. So to go from the attic to the basement everytime I need to do something on another machine is not practical, and the only other machine I need to access on a regular basis is the Debian box in the basement, this makes the most sense.
I also have a 14 year old living in the house and he's fascinated by all this and will meddle in anything he gets the chance to so all the Linux machines and network hardware need to be behind lock and key.

I need some help to setup a simple 2 screens extended desktop. From my laptop with an nvidia card, it was very easy and done in seconds. But with my new desktop loaded with amd hardware, it's turning into a nightmare. I've posted on details of my hardware and of this problem here, and I'm encountering new trouble. Since then, my xorg.conf has changed a little without success:

Im running 64bit centos 5.6 and using virt-manager.On one of my guest OS's, Windows 7, The max Physical CPUs is 2, you can have unlimited CPU Cores however. (like my machine i use for work has 1, 4 core processor).The issue im having is xen only allows you to set the vcpu arguemnet in your xen config file. How can i set it so that 1 CPU has several Cores just as windows would recognize this machine if i were installing directly to the hardware vs via a VM.Ive searched for 2 days staright trying to address this issue, very little progress, Does anyone know where a XEN support forum is? all i get is the citrix xen support forums.
here is the best info i have found on this, but i dont know how to change this for my CPU to work, when i enter this in my xen config it essentially ignores it and just takes the value of vcpu= so windows shows 2 CPUs each with ONLY one core. Id like 1 or 2 CPUS showing Several cores.The physical Hardware is 2x Xeon 5300 Quad Core CPUs.

After having followed the guide in the link below
Multi-media and Restricted Format Installation Guide
I tried to reproduce MP3 files on video like .AVI or MP4 and everything was fine.Every program and library seems that has been installed correctly.
But when I checked , following the instructions in the link, I found different results. I can understand that the guide has been written a long time ago and some packages are not available anymore in the repository, but I think there are too many differences.
This is what I got:
Code:
And I got the following list
Another differerence that I have noticed is: when I was listening a MP3 file using Amarok the music was quite clear and loud, but when I reproduce a MP4 or MP3 video file using VLC I could bearily hear something and the volume was at its maximum. How can it be ?

When I first started using Unity, I configured the dual monitor system under the settings program. I then changed my xorg.conf, but Unity is ignoring that configuration and switching to its own. I think this might have something to do with RandR, but I'm not sure. Is there a way to make Unity use the xorg.conf configuration?

I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).
