Ubuntu Multimedia :: Running A Multi Monitor Setup With Xinerama?

Jan 18, 2011

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.

Hardware :: ATI Multi Card Multi Display Xinerama Composite

Jun 24, 2011

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).

Ubuntu Multimedia :: Apps Start On Wrong Monitor Using Xinerama

Jan 23, 2010

I use 2 monitors under Ubuntu 9.10, but I have them set up in a unique way. The primary (CRT) faces me on my desk, but the other (widescreen LCD) is turned away from me, because I use it only to watch movies from my couch. My video card is an Nvidia GeForce 9800 GTX+, using the proprietary Nvidia driver package, with Xinerama turned on, so the desktop extends across both displays. Given that setup, is there any way to control which display applications open upon? Several apps have started opening on one display or the other, seemingly at random. Further, some apps start on the primary display, but open their subwindows on the secondary display. It's very annoying, because I can't see the second screen, so I can't drag the windows back to the primary desktop.

I would also like to have VLC Media Player (or any other app) always open on the secondary screen, on purpose. I almost never watch movies sitting at my desk, but rather from the couch. I placed a VLC launcher icon on the secondary screen, but when started it opens on the primary display. (If you're wondering how I can click on anything from my couch, I have a wireless mouse there in addition to the wired mouse at my desk. It's my "remote" since I don't have a TV. Xorg will quite happily support 2 or more mice simultaneously, I discovered.)

Ubuntu Multimedia :: Triple Monitor Xinerama - Cursor Movement Limited

Jun 6, 2010

UPDATE: I can get the wrapping to stop, but it offsets the image between monitors. It's like the center monitor's image was stretched upward, distorting the alignment with the side monitors, rather than just providing additional space at the top. If I switch it so the two side monitors are 120px lower than the center, (as i had it in 9.04) then the wrapping issue occurs again. This is frustrating. I could use some help. (64-bit Ubuntu 10.04)

After lots, and lots, and lots of googling, configuring, experimentation, and even unplugging and replugging, I finally got all 3 monitors working like I had them in 9.04... Or almost. The center monitor is larger than the two side monitors, being 1920x1200 compared to 1920x1080. When I move the mouse pointer on the center monitor, it hits a ceiling and disappears right around that extra 120 pixel area on top, and can be seen at the bottom of the screen.

Ubuntu :: Multi Monitor Setup With 2 Graphics Cards

May 18, 2011

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.

Fedora :: F15 Still Crashes On Multi Monitor Setup

Jun 5, 2011

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.

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.

Ubuntu Multimedia :: ATI Multi Screen Big Desktop To Setup On 11.04?

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.

Ubuntu :: Xinerama And Dual Screens - Create Another Panel On The 2nd Monitor?

Jun 6, 2010

I'm having some issues getting my two monitors (both 1600x900) to work well with Xinerama. The first thing I'm having trouble with is getting 1 wallpaper to span across both monitors..from what I've googled it's sounds like I'm not the first either The 'span' function in the change wallpaper window doesn't do it. The second thing is that I would like the panels to stretch across both monitors well, or at least be able to create another panel on the 2nd monitor which I can't do now.Here's my xorg.conf file:

OpenSUSE Hardware :: ATI Dual Monitor Xinerama With Different Resolutions

Apr 20, 2011

Today I bought a new monitor (IPS236V) to use it to watch movies and tv while I'm working on the other one.. I thought it's the best to activate Xinerama which could be done easy via CCC. But I'm not able to change the resolutions now as these panels are disabled in CCC. The first monitor is set to its native resolution, but the second is something lower.How can I configure both monitors to there native resolution?

General :: Xinerama - 3 Monitors Setup (Slow And Laggy)

Dec 23, 2010

I currently have my monitors set up as an extended desktop using Nividia's Xinerama function. Everything works sweet, except it's acting slow and lags out. It all works out fine when Xinerama is disabled. At the moment, I'm using CentOS with Gnome, but I've tried other distributions with the same outcome. If I can't a fix I'm going back to windblows.

Computer specs:3 monitors
2 Nvidia GTX 275 GFX cards

Software :: Xinerama Multihead Setup With NVidia 9800 GT?

Jan 30, 2011

Recently installed Slackware, and now trying to get my two monitors working nicely. After much hair-tearing I've got Xinerama set up so that each monitor displays separate information.I'm using an nVidia 9800 GT dual-headed graphics card. This is my xorg.conf file:

Code:

Section "ServerFlags"
Option "Xinerama" "ON"
EndSection

[code]....

then the mouse is stuck on the right screen. It seems to recognise that the physical right monitor is the virtual right monitor, but if you try to move off the left side of the screen, it appears on the right side of the same screen. This seems to be similar to the bug described here, but that's meant to be fixed in v1.2.3 and I have v1.5.0 (according to pkgtool). I have also considered physically swapping the monitors, but then I would have to edit all the other OSes I use to know about the change, and also on principle I feel I should work out why it's not working...

OpenSUSE Install :: Xinerama Config - Adjust Xinerama To Place 1 Desktop On Each Of 2 Monitors And Not Stretch A Single Over Both

Jan 10, 2010

I would like to adjust Xinerama to place 1 desktop on each of my 2 monitors and not stretch a single over both. With the current set up there is a problem with window placement upon opening new widows or context dialog boxes. I realize that I could adjust placement properties and select window placement with the mouse but this is still lacking in productivity. My monitors are not next to on another so this is more of a problem than it seems.

Ubuntu :: Three Monitors - Xinerama And Cannot Get Desktop Effects Running At Normal Or Extra

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).

Ubuntu Multimedia :: Get 2x Videocard, 3x Monitor Setup To Work In 9.10?

Mar 30, 2010

Suppose i'm this guy right there:[URL]..And all i'm used to seeing is this:[URL]..And clearly NOT this:[URL].. And my technical expertise dates back to early eighties, a few lines of x86 assembly and a few lines of C. And i haven't written a single line ever since (got bloody rich since win 3.1 shipped).

How can i get my gorgeous (20" portrait 30" 20" portrait) setup workin'? Just like in ol' good win xp - each monitor is handled like a separate entity not merged together in one big screen? A step-by-step guide would be perfect!

Both v-cards are ATI, supposedly working from the same drivers. I don't mind using a different linux distribution, if it makes matters any easier.

Ubuntu Multimedia :: Can't Play Movies In Dual Monitor Setup

Jul 22, 2010

I recently got a signal conversion box so I could route my netbooks monitor-out port to my TV. The idea being that I could effectively set the TV up as a separate monitor for watching movies on whilst I worked using the netbooks own monitor. It seemed to work initially, the Monitors dialog box could easily detect and setup the TV as if it were just an external monitor however I can't seem to play any kind of video on either screen when this is set up. All I get in Totem, Mplayer, VLC and skype is just a black area within the applications window. The sound works fine so this is clearly just a video problem.

It only seems to occur when I configure the system to use the TV as a separate monitor. If I tell it to display the same thing on both monitors all video output works fine.

Ubuntu Multimedia :: GLX Video Acceleration With ATI/NVIDIA 3-monitor Setup ?

Jun 25, 2011

I'm currently running a three-monitor setup, two of the monitors being connected to an NVIDIA card, and the third being connected to the motherboard's onboard ATI adapter. This works, and it actually works quite well, but after installing the nvidia-current drivers (using the GNOME dialog), I am unable to get any video acceleration going. The GLX module doesn't seem to want to load, and while I'm actually quite impressed with the video performance I'm getting with the open-source drivers, I'd really like to have the OpenGL capability, as it does make things look prettier.

Relevant configs and logs are below.

I should clarify - I don't care about the 3rd monitor on the ATI adapter; I'm only concerned with getting OpenGL working on the two on the NVIDIA - if that's possible, which it may not be...

Ubuntu Multimedia :: Defining Primary Display ( 3 Monitor Setup)?

Jul 6, 2011

I have a Radeon HD 5830, running 3 monitors on 10.10 64bit with the 10.6 video driver. The three monitors ( from left to right ) :

DFP1 : 1152x2048
DFP2 : 1920x1200
CRT1 : 1360x768

The problem I'm having is getting the middle monitor to be the primary one.

Running
xrandr --output DFP2 --primary

puts the panel on the middle screen but my docky and icons stay on the left screen. Flash videos also open up on the portrait left monitor which looks awful. Ideally I would like the icons on DFP1, docky on P2 and flash videos to open on P2. But I would definitely settle for everyone to be on the middle screen and drag it around as I please.

Debian Multimedia :: Triple Monitor Setup On Wheezy

Apr 29, 2015

I have some very strange issues with my tripple monitor setup on debian wheezy. I have acer aspire V3 laptop with i915 Intel (Intel® HD Graphics 4000) as part of i3 and nvidia GT 740M which I never managed to get working with or without optimus to any degree whatsoever. What I want is a reliably working triple monitro setup. I have 2 additional DELL u2412m monitors which I did manage to get to work on few occasions by more or less randomly turning stuff on and off via lxrand and KDE systemsettings (so I do knwo for a fact that tripple monitor setup works). Arandr doesn't work, and executing xrandr from cmd doesn't work. I can relatively easily get the 2 monitors to mirror each other, but to get them to work separately is extremy difficult. It's always the same error but the well known crt. For example:

xrandr --output VGA1 --mode 1920x1200 --pos 3840x0 --rotate normal
xrandr: Configure crtc 2 failed

xrandr --output VGA1 --mode 1920x1200 --rotate normal --right-of LVDS1
xrandr: Configure crtc 2 failed

When it did work I copied arandrs script in hopes it would work, but it doesn't. Obviously, here is the issue that the crtc can not be configured so if somoen could tell me why and how to get the damn thign to use a specific crtc it would be awesome. Also, I noticed that when I hit "identify monitors" in KDE systemtools, it would say VGA HDMI for both VGA and HDMI outputs.

Here is xrandr output from when it worked:

Code: Select allScreen 0: minimum 320 x 200, current 5760 x 1200, maximum 8192 x 8192
LVDS1 connected 1920x1080+1920+0 (0x46) normal (normal left inverted right x axis y axis) 382mm x 215mm

        Timestamp:  143521
        Subpixel:   horizontal rgb
        Gamma:      1.0:1.0:1.0
        Brightness: 1.0

[Code] ......

Here is now:

Code: Select allScreen 0: minimum 320 x 200, current 3840 x 1200, maximum 8192 x 8192

Ubuntu Multimedia :: Dual Monitor Setup - Separate X Screen Option

Feb 18, 2010

I've played around with a second monitor, but so far I haven't found a satisfying solution. I am using a laptop with a GeForce 9600M GS graphics card. I have managed to set up twinview, but my monitors don't have the same height so I'd rather have something like the "seperate x screen" option. Or how I imagine that option would be like. After some problems with the nvidia configuration tool (I couldn't change the xorg.conf, until I read this: [URL] I now have two separate screens, but the second one is all empty, with black background and X-shaped mouse cursor.

There seems to be no window manager running, I can start programs there with -display :0.1 , but they don't get any frame decoration and, which is worse, no keyboard focus. I'd be fine with a fullscreen konsole there, so I don't really need a window manager, but I do need access from the keyboard. I'd prefer a setup that would allow me to easily (without editing xorg.conf) switch between using both monitors and using only one, because I don't always use the laptop at home.

Debian Multimedia :: Dual Monitor Setup - Two Identical Outputs

Sep 2, 2015

Just installed Debian 8, coming from Ubuntu12, it seems I cannot get my dual monitors to work as it should.

I want two monitors side by side, currently I have two identical outputs. I looked around a bit and register two possible problems.

root@bigcem101-debian:/home/bigcem101# xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 400, current 1024 x 768, maximum 1024 x 768
default connected primary 1024x768+0+0 0mm x 0mm

1024x768 0.00*
800x600 0.00
640x480 0.00
720x400 0.00

Hence, problem 1: it is as if there is only one monitor detected. Then I tried to look for Xorg.conf ..... and: problem 2 xorg.conf is not there. This seems to be normal but when I installed my Ubuntu years ago it was still there and one could manually set things. There must be something new I am missing.

Card:
VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV670 [Radeon HD 3690/3850]

It seems I have both ati and radeon installed.

root@bigcem101-debian:/home/bigcem101# X -configure
(EE)
Fatal server error:
(EE) Server is already active for display 0

I am clueless.

Ubuntu Multimedia :: Laptop Monitor Running With 61hz Instead Of 60hz When Activating KMS?

Jul 4, 2010

today i was trying to activate KMS by adding:

Code:
radeon.modeset=1
to grub.

it worked fine, and fixed the black-box bug in cairo-dock, and i finally had a nice graphic bootscreen again.

but another bug occured: im running dual-screen setup, my notebook is connected via vga to a dell 22 inch widescreen TFT.

by default both screens running with 60hz and no problem.

now, after activating KMS it happend that, while the dell monitor still ran 60hz, the notebook screen was running with 61hz! it was shown in the monitor-options.
the notebook monitor was therefore flickering a bit for 5 seconds, than running fine for another few seconds. then flickering again. (obviously, as 61hz is too much when it should run with 60hz!)

so my question is: how can i activate KMS again and have both of my screens running with 60hz again? is there an option?

Ubuntu :: Multi Monitor Support (Different Resolutions)

May 13, 2010

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.

Ubuntu Multimedia :: Can't Enable The Xinerama / Extended Screen

Aug 26, 2011

I have done a fresh install of ubuntu 11.04. Everything is fine, Ubuntu seemed to be using the opensource ati drivers upon first boot.
Then prompted that I install the ati catalyst control center/drivers from additional drivers which I did.Again smooth sailing untill I decided to enable my HD tv (hdmi) as my secondary screen. This again worked fine cloned. But I could not enable extended. The option is available but requires xinerama to be enabled.

After restarting I could not login. Read up on this and others have has this issue with different cards. I proceeded to login to ubuntu (no effects) session and then swtiched off xinerama. (this did work in this session). The issue is getting it to work with unity. Logged back into unity now but I don't know how I can enable dual screens in extended mode. There are recomendations on other threads advising to use the open source drivers. But these don't work correctly. The card I am using is an ASUS EAH5570. This I believe has the radeon 5570 chip.

Ubuntu :: 10.04 LTS - Dual Monitor Works Only Sometimes (ATI Multi-desktop)?

May 19, 2011

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
