• NVIDIA X Server TwinView isses with 2 GeForce 8600GT cards

  - by Big Daddy

  Full disclosure, I am relatively new to Linux and loving the learning curve but I am undoubtedly capable of ignorant mistakes I have a rig I am building for my home office desktop. The basics: Gigabyte MB AMD 64bt processor Ubuntu 12.04 64bit two Nvidia GeForce 8600GT video cards using a SLI bridge two 22" DVI input HP monitors So here is my issue (it is driving me nuts) with X Server. If I plug both monitors into GPU 0 X Server auto configures TwinView and all is grand, works like a charm, though both are running off of GPU 0. If I plug one monitor into GPU 0 and one monitor into GPU 1, X Server enables the monitor on GPU 0, sees but keeps the monitor on GPU 1 disabled. My presumption (we all know the saying about presumptions) is that all I would have to do is select the disabled monitor on GPU 1 and drop down the Configure pull down and select TwinView...problem is when the monitors are plugged in this way, the TwinView option is greyed out and can not be selected. What am I not understanding here? Is there some sort of configuration I need to do elsewhere for Ubuntu to utilize both GPU's? Any help will be most appreciated, thanks in advance.

• Twinview broken on upgrade to ubuntu 10.10

  - by mapkyca

  I have been on 9.10 for over a year on the grounds that if it ain't broke, don't fix it. However, I had a spare weekend and figured it was probably about time... I performed an upgrade to 10.4, and everything seemed to proceed smoothly, so I took the plunge and went for 10.10. Disaster. My twinview Nvidia display which had been working perfectly is now broken. On boot everything seems fine, but when X starts and the second monitor springs into life the primary winks out and switches off - almost as if its been put into an unsupported display mode. The system seems to think there's a second monitor - the nvidia logo is split across the two screens, but it can't seem to start. Things I've tried: Swapping the monitors (one is older than the other, and its definitely the port not the actual monitor) Rolling back to an old Xorg conf from prior to the upgrade Installing a non-beta driver direct from Nvidia (this seems to start both monitors but then apparently stops boot and causes the second display to 'wink'. Twinview seems non-functional, both displays are mirrors) Disabling EDID Disabling twinview, logging in and attempting to use the Nvidia config to re-detect the monitors (second monitor is falsely detected and won't go higher than 1024x768. Selecting 'apply' causes one screen to go blank and the other to display garbage) googling for about 5 hours looking for similar problems, none of the offered solutions seemed to work I'm at a loss, and it is looking very much like I'm going to have to go through a time consuming reinstall to downgrade back to the working 10.4. Any thoughts?

• Ubuntu 12.04 nVidia TwinView tearing

  - by Andy Turfer

  I'm running Ubuntu 12.04. Today I just purchased a second monitor (I have a Dell U2711 and a 42-inch Sony TV). I'm running the 295.49 proprietary nVidia graphics driver, my graphics card is a GeForce GTX 460. I am not able to activate "xinerama" with "separate X screens", not sure why. I am able to use TwinView. This works, although it results in severe tearing on the Sony TV. It's as though "sync to vblank" isn't working (I have this set in Compiz and in the nVidia settings). If I disable the Dell U2711 and only use the Sony, everything works fine, zero tearing. Is it the case that "sync to vblank" can only work on a single monitor in Ubuntu 12.04? Is there any way to get rid of the tearing on the second monitor in TwinView mode?

• configuring separate X screens instead of TwinView

  - by fimre

  My Sony Vaio laptop is connected to an external Samsung monitor and my nVidia driver is configured in TwinView mode. Everything is OK with this, however, I can not adjust my displays individually so at the moment my external display is a little bit darker which disturbs me a lot. I tried the Separate X Screen mode but after restart, my laptop display was white with a black x sign mouse pointer and the external display normal desktop. Is it a bug or something I missed? The idea is that using Separate X Screen mode, I could adjust my displays individually. I would really appreciate someone would guide me out of this situation. Thanx in adv..

• Updating NVIDIA drivers from 295.40: What will happen to TwinView?

  - by Spice

  Right now, I have the NVIDIA proprietary drivers enabled without the Ubuntu-X repo, so the driver version is 295.40 (which is on the official Ubuntu repo) instead of the current 304.64 for my card, but I want to update to the current (using the Ubuntu-X repo). From what I heard, after 302.xx, NVIDIA started supporting RandR and removed TwinView. My question is, I have TwinView enabled for two monitors. If I update to the new version, what will happen to my TwinView settings? Will there be any extra work to do to migrate to the new driver?

• Linux Twinview : copy window application to both screens

  - by Dom

  I use the SUN Presenter Openoffice Extension with a twinview Ubuntu laptop. it works well : I have the video-projector with my presentation and my laptop screen with the slides (and time...). My problem is when I want to present a mono-screen application, like Firefox, gnome-terminal. It is displayed only on one monitor, which is not really efficient if you want to be interactive. Is there a way to display these types of application on both display and to interact with both ? Thanks

  - by knittl

  i bought an external monitor and can't get it to work properly with my laptop screen. my laptop screen has a resolution of 1920x1200 and the new monitor has 1920x1080 when i open nvidia-settings and select the maximum resolution for each of the screen, one screen will always stay blank. if i select a smaller resolution for one of the two it will work. 1920x1200 + 1440x900 = works 1680x1050 + 1920x1080 = works 1920x1200 + 1920x1080 = doesn't work (but that's what i want to have!) my graphics card is an 01:00.0 VGA compatible controller: nVidia Corporation Quadro FX 360M (rev a1) (output from lspci), driver is proprietary nvidia driver, operating system is ubuntu. any help greatly apreciated

• Windows expand over 2 monitors in quad-monitor setup

• Double launchers and mouse captured between screens in Twinview configuration

  - by Numpty

  Just upgraded to 12.04 and noticed an extremely annoying issue. While using twinview, there now appears to be a launcher on each screen. Moving the mouse between monitors and over the launcher "captures" the mouse for half a second or so, creating the perception of lag. According to some bug reports I've read it appears that a launcher on every screen is a new "feature". Is there any way I can get rid of the 2nd launcher? It's driving my crazy.

• If I run two monitors from two different graphic cards, can I still have Twinview?

  - by rumtscho

  I am planning to get a second 2560x1440 monitor for home. The trouble is, I only have 1xDVI, 1xVGA on my graphics card (a 250 GT). I don't want to buy a new graphics card until the prices for the 500 series have stabilized, so probably not before summer (or will it happen earlier? I don't remember how it was for other series, and I couldn't find long-term price history for video cards). The solution I had in mind is to get the 7600 GS from my old PC, which also has 1xDVI, 1xVGA, and run each monitor on a separate card. I have never done that, and I was wondering 1. If I will be able to run the monitors in Twinview then, or will I be stuck with separate X sessions, and 2. Whether there are some other disadvantages as compared to a single-head graphics card. (I am using the proprietary driver because I need compiz). As an aside, how do I find out whether the DVI port on the old graphics card is dual link?

• Unity doesn't autostart on second X screen

  - by Nonoo

  I have two Nvidia cards both with 2 heads and both configured as TwinView, so I have Screen0 and Screen1 in my xorg.conf. ccsm sees both screens (displays them in the Screens drop-down at the top left), but Unity starts only on Screen0 by default. The displays on Screen1 only show the default white screen and default X mouse cursor, when I hover over them. Is this the normal, expected behavior? Can I start Unity on Screen1 automatically without running custom shell scripts (like DISPLAY=:0.1 compiz --replace)?

• Nvidia Fullscreen Metanode "Sliding" Issue

  - by user68202

  i have 2 monitors, the left one is my "main" monitor with 1920x1080_120, the right one my second with 1680x1050_60. (i have a nvidia card setup with twinview) when i play a game or something in fullscreen mode, the full resolution is used in fullscreen (monitor 1 + monitor 2). i read something about the metanodes i can use to shut down the one monitor that i dont need durning a "fullscreen session". i used the following: Option "metamodes" "DFP-0: 1920x1080_120 +0+0, DFP-2: 1680x1050_60 +1920+0; DFP: 1920x1080_120 +0+0, NULL" Its working great, the second (right) monitor is shutting down when i press "CTRL ALT +" and is starting agin when i press the same keystroke. But in the second mode when the second monitor is "down", i got the full "monitor 1 + monitor 2" resolution on my first (left) monitor, i can move my mouse to the right to see the contents of the second monitor and move it again to the left to the what is normally seen on the first monitor. Its something sliding between the 2 monitors on one display. How can i avoid this?

• Ubuntu Nvidia Xorg Twinview doesnt like my monitors

  - by Andrew Bolster

  Basically, using the latest available ubuntu drivers (195.36.15) I cannot for the life of me get my two monitors to operate at suitable resolutions. When not using the drivers atall and going single-screen, both monitors support 1680x1050, but this option is only shown for one monitor in nvidia-settings, and when i manually add a metamode into the xorg.conf, it just gives up initialising the second screen.

• Wine causes twin view to break

  - by deanvz

  I have endlessly been playing around with the Nvidia X Server settings and changing my xorg.conf file to try and work for me and on most days its fine. In each instance I get it working for a while and then this morning the most bizarre thing happens. The moment I open any type of Wine program (which never use to be a problem) my Twin View setup disappears and am left with mirrored displays. I try and change the settings in the Nvidia driver, but its not interested and the screens remain mirrored. I have a work around. Restart my pc...

• How to configure multiple video cards in linux?

  - by Jader Dias

  In Ubuntu Lucid Lynx RC, I got NVidia's TwinView to work with 2 monitors in a single video card. But when I use the same monitors but split them between the video cards I can't make TwinView work and it starts a X server for each monitor. I want the same effect I had with one video card.

• Nvidia: force 1920x1080 as an option

  - by progo

  Proprietary Nvidia (290) on gentoo here. I'm running Nvidia TwinView with two 1680x1050 monitors here. Now I want to hotplug between HDTV and one of the monitors. Almost good, but since Nvidia reads the EDID information of the monitors and sees the maximum resolution of 1680x1050, it won't allow 1920x1080. "Detect displays" of nvidia-settings doesn't do anything. My only option this far is to restart X, but this is highly unpreferable. I already discovered that something towards my liking can be done with MetaModes, but it doesn't allow larger resolutions either. I guess I have to drop the EDID information and specify modes manually. However, TwinView hasn't liked my offerings thus far.

• Cloning (mirroring) laptop display to area of external monitor display

  - by intuited

  I'm using Maverick "10.10" Meercat on a HP Pavilion tx2110. This machine has an NVidia Go6150 graphics card, and sports a 1280x800 display. I have an external monitor which can do 1280x1024 resolution. FWIW I'm using openbox as my window manager; as I understand it this shouldn't be a factor. I'd like to clone the display to the monitor, so that the size of the desktop remains at 1280x800, and there is a horizontal blank area on the external monitor. I.E. I want to avoid having to pan the display of the desktop on either monitor. So the actual resolution of the monitor would be 1280x1024, but the resolution of the section of the monitor where stuff was actually being displayed would be 1280x800. Using the nvidia-settings applet, I'm able to set up the cloned display so that the desktop size is 1280x1024 (the resolution of the external monitor), but can't find a way to instead have the desktop size stay at the resolution of the laptop's built-in display. Is this achievable? Ideally I'd like the external monitor's blank area to be at the top of the screen, i.e. for it to align the display with the bottom of the screen.

• twin view on gnome when monitor is unplugged

  - by james t

  i have a macbook pro which is often connected to a monitor, twin view on gnome works pretty well, but a problem arises when i disconnect the monitor, any window that resided on that workspace is no longer available. another issue is when i start my computer when a monitor is not present, because xorg.conf file has the monitor configuration in it, my mouse pointer often disappears in the other monitor's virtual space, as if it is currently plugged, osx deals with this issue elegantly by refreshing the display every time a plug in/out occurs, is there anything similar that can be done in linux ?

• Is there going to be Twinview ( or alternative) implemented for nouveau ?

  - by lisak

  as I've had heavy issues with nvidia driver regarding performance of basic X window operations (window moving, resizing, scrolling). I switched to nouveau driver. But I lost the possibility of having dual screen that I had previously thanks to nvidia twinview feature... Anyway I rather have fluent X than dual screen, but having dual screen would be nice, so I'm wondering if there is already an nouveau alternative to nvidia's twinview or if it is going to be implemented.

• Running Ubuntu with multiple monitors having a panel each

  - by Andreas Grech

  I have just installed Ubuntu and I'm trying to set up a correct configuration for having multiple monitors. I want the two monitors to have their own workspaces, yet the ability to drag a window from one monitor to the next. I also want a separate panel (taskbar) for each monitor. I have played around with nvidia-settings and tried the following different configs: Having both monitors `Use separate X screen" A panel for each monitor but I couldn't drag windows from one monitor to the next Using TwinView The ability to drag windows from one monitor to the next but only a single panel for the primary display Now I want to have the above configurations combined. Basically, as I stated beforehand, having a separate panel for each monitor and also the ability to drag windows across monitors. Can anyone provide me with suggestions please?
