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.

Ubuntu Multimedia :: Separate X Screen For Dual GPU?

Sep 1, 2011

I'm trying to get my Dual Monitor setup working. I have a 1900x1080 LCD and a 1280x1020 LCD. Cards are dual nvidia 7600GT.

I had the system set up using TwinView for a while but I opted to switch over to "Separate X Screen" so that the two displays could serve as separate desktops with different functions. Initially they were both running off of GPU0 and everything was fine. I then decided to swap the smaller monitor over to GPU1 to make better use of my available resources. I have no issue using the nVidia configuration utility and all appears well but when I respart X it comes up with a black screen and a white mouse cursor and then just lags. The mouse moves initially but after a few minutes it freezes and the whole system locks. I have to hard reboot and then it comes up with only one monitor. Inspection of the xorg.conf file shows that it has disabled the second monitor in order to start X.

Can someone look at my xorg.conf and see if there's anything obvious that would cause it to break? Is there some issue with separate cards that is fundamentally different from a dual-head card?

Code:
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 1.0 (buildd@yellow) Fri Apr 9 11:51:21 UTC 2010
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 1.0 (buildmeister@builder62) Wed Nov 11 06:45:14 PST 2009

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.

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.

Debian Multimedia :: Dual Monitor Setup On Intel Chipset - Netinst Minimal Install

May 14, 2010

I'm trying to get dual monitors working on a fresh install of debian from the netinst install cd. I did not allow the installer to download any packages and then manually installed xorg gnome-core & gdm using apt-get.

The monitors are plugged into the onboard vga and dvi ports of my motherboard. I believe the chipset is intel.

At the moment the displays are cloned.

I don't know much about xorg.

This is my xrandr output:

Ubuntu Networking :: VNC And Dual Head Setup (separate X Screens)?

Jan 2, 2011

I have my computer set up to use separate x screens for both of my monitors and almost everything works perfectly. With this set up I don't have any problem displaying flash in full screen on either monitor like I had with twinview. I have it set up this way so that I can use my TV to display mythtv and still use my computer monitor to browse the web, etc. The only problem is that I use my iphone with hipporemote to give me a wireless keyboard/mouse. When using twinview this was not a problem as it was just one large desktop spread over two monitors.

However, switching to separate x screens seems to have broken the functionality of the vnc server. When using my physical keyboard and mouse I can just move the cursor off the side of monitor 1 to control monitor 2, however, if I'm connected via vnc the cursor gets "trapped" inside the active monitor. I can interact with each screen as expected but if I want to switch the mouse/keyboard focus to the other monitor I have to go to the computer and move the mouse to the desired monitor, which obviously defeats the purpose of using the iphone as a wireless remote.

So my question is this. Is there a way to assign a hotkey combination to switch the focus of keyboard and mouse that the vnc server is controlling? Or could I set the vnc server to only control one of the two x screens?

Ubuntu Multimedia :: Dual-monitor Mouse Position Jumps When Moving Off-screen

Nov 4, 2010

I have a dual-screen set-up with Ubuntu 10.10. I have an ATI Mobility Radeon HD 5650 video card. I use my lower-resolution laptop screen on the left and a larger monitor on the right. The monitor is also physically higher than the monitor. See attachment for a screenshot.I have correctly set up my displays so that if the mouse is in the middle of the screen it can move from one screen to the other without jumping. The jumping happens when moving off of one screen in an area where the other screen is not directly next to it (some people call this 'the void').

Example: (See the attachment for a visual example of this.) My mouse is in the external monitor (right monitor). As I move the mouse to the top-left of the monitor (position 1), I by mistake go a little too far and instead of hitting the Ubuntu applications menu, I ended up at the top-right of the laptop monitor (left monitor; position 2). I quickly realize my mistake and move the mouse back to the right monitor, but now the mouse is at the middle-left position (position 3).This same error occurs by moving the mouse on the laptop monitor (left monitor) passed the bottom-right position. This is a big problem when scrolling vertical scroll bars on the laptop monitor (left monitor).I am looking for a fix that if the mouse is at position 1 in the attachment and I move the mouse left, it stays at position 1 and does not go to position 2.

Ubuntu Multimedia :: Setup Dual Screen Display On Computer With Nvidia Optimus?

Aug 17, 2011

having trouble setting up a dual monitor from my Dell xps laptop using an HDMI port. It dual boots onto Ubuntu 10.04. The computer has a Nvidia GeForce GT 555M with Optimus graphics card I need to make sure I have not installed the restricted drivers. So I think what is happening right now is that the graphics are shown off the integrated graphics card. This is my output from <lspci | grep VGA>

Code:

00:02.0 VGA compatible controller: Intel Corporation Device 0126 (rev 09)
01:00.0 VGA compatible controller: nVidia Corporation Device 0dcd (rev a1)

The forum recommends to use this program called Bumblebee but I have had some issues with that in the past. Is there somehow I can setup my dual display while staying on Ubuntu 10.04 and not installing Bumblebee? I have researched into setting up dual display walkthroughs before but they all concentrate on nvidia or ATI configurations.

Ubuntu :: Dual Monitor Setup Clones On Login ?

Jun 29, 2011

I'm using the proprietery nvidia drivers on 11.04. I have a dual monitor setup with xinerama. The login screen appears to work fine, I can move my mouse between screens, and only one screen (right) has the login prompt. When I login, both screens show the same thing. While I can move my mouse across, I can only interact when it's on the left side.

I found this: [url], but I cannot start the display settings in the XFCE control center due to "missing randr extentions". Yesterday, I was using Kubuntu 11.04 on this same machine, and the dual monitor setup worked fine.

Hardware :: Dual Monitor Setup In Fedora 13

Dec 27, 2010

I am running Fedora 13 on a PC I built myself - MSI motherboard 785-E53. It has onboard DVI which my primary monitor is hooked to. I added an older 17" CRT to the onboard analog output and the main desktop with my icons and panels immediately switched to the CRT. Kernel is 2.6.34.7-66.fc13.i686, lspci -v says VGA compatible controller ATI Technologies Inc RS880 (Radeon HD 4200). How can I get flatscreen on the DVI output to be the primary?

Slackware :: Boot Into Dual Monitor Setup ?

Jun 15, 2011

I created a dual monitor setup in Slack 13.37 using the KDE systemsettings -> Monitor Setup function. (Sadly I had to rebuild ~/.kde in the process, but that's a different story.)

I verify that ~/.kde/share/config/krandrrc contains the new monitor setup (both screens active). I have saved a startup session with krandrtray running. However, when I logon, the system always starts with both screens in clone mode. I always have to go into systemsettings or krandrtay and redo the dual monitor configuration.

Is there a better way? Do I have to create a suitable xorg.conf (which I will try when I get home) or is there another way to boot into the dual config automatically?

Ubuntu :: Change Primary Display On Dual Monitor Setup?

Mar 10, 2010

I just installed Ubuntu 9.10 this evening. I have a Nvidia Geforce 8500GT video card with two monitors hooked up (one to the cards VGA, the other to the DVI). I installed Nvidia drivers and Ubuntu is working with both monitors fine.

The problem I am having is it chose the monitor plugged into VGA as the primary (uses that monitor for the toolbars) when I really want them to go on the monitor that is plugged into DVI. Is there anyway for me to switch which monitor Ubuntu treats as the primary?

Ubuntu :: Setup A Dual Monitor On System / ATI FireGL V3100 / 8.04

Mar 11, 2011

I am trying to setup a dual monitor on my system. I have gone through many posts and did the following.Downloaded EnvyNG to download relevant ATI drivers and eventually I got to a point where I can see that ATI is listed under Hardware drivers. But, from here, how do I actually set dual monitors?. I am looking for some interface like Catalyst, but couldn't find one after the drivers got installed. What am I missing here?I went back and forth, but after restarting the PC, the resolution goes to 800X640 and I have no option of setting dual monitors. I reset the options in /etc/X11/xorg.conf to let Ubuntu use the default drivers.

Ubuntu :: Dual Monitor Setup Does Not Work Whenever Install Drivers

Sep 1, 2011

When ever I install the (recommended) drivers through the "Additional Drivers" interface to run Unity my dual monitor setup does not work. The monitors won't even detect correctly what so ever. Then, when ever I install (more basic?) nVidia drivers through the packet manager, my dual monitors work as planned, but now Unity won't work. What's the deal? Are there any work arounds for this?

OpenSUSE :: Dual Monitor - Nvidia Driver With X Screen - Shows A Black Screen

Feb 5, 2011

I have openSUSE 11.3 with an nvidia card connected with two monitors. In the past I used xinerama which was ok, but now I need to have two separate desktops, one on each screen. I set the nvidia driver with x screen, and now one screen works perfect and the other only shows a black screen. When I move the mouse over the black screen, the mouse pointer turns into an X, but moves correctly, which seems to me that the problem is that I need to set the second desktop to that screen. I looked on forums on how to do so, and no luck.

Ubuntu :: Dual Monitor Setup - Mouse Pointer Misplaced And Other Bugs?

Mar 23, 2011

Right now, I need to use a dual-monitor setup. Be it for my casual desktop usage, or to my projects and programs presentations with a slideshow. The latter is critical and that's why I'm here.So, after some Intel Drivers update, some programs started to work nicely, faster and beautifully. But it corrupted my Dual-Monitor Setup. I don't know what to say, I'm totally desperate. I had to show one of my programs to my teacher using a projector, but with the dual monitor corruption, I called in sick today. I need to use the netbook screen to make changes on the program and the second monitor/projector to show the program working.

I'll show some pictures, but I'm without a camera right now, so I'll use one china-phone that's hanging around here to take a picture. Sorry for the quality. Both Monitors, you can see on the right of the bigger one the corruption I'm talking about.

OpenSUSE Hardware :: Dual Monitor Setup Lost After Reboot

May 20, 2011

I'm trying to get an external monitor hooked up to my laptop with the intention to use both simultaneously using TwinView. Actually, I'm not "trying to make it work": everything works fine, using NVIDIA X Server Settings. However, when I reboot these settings are lost and I have to manually expand my desktop again.

I've found that running NVIDIA X Server Settings as root should allow one to "Save to X Configuration File", in order to let it automatically load the right settings. When I click this option, however, I'm asked to manually provide a file name with my home folder as the default location. I'm confused how to proceed - where should I save this configuration? Or should I be taking a completely different approach in the first place? (note: KDE 'Display and Monitor' doesn't work. Only when I use the NVIDIA-thingy KDE will recognize that my desktop is expanded to a 3600x1080 resolution)

Hardware :: Momentary Blanking Of Screens With Dual Monitor Setup

May 6, 2011

I did set up dual monitors few times on few of my boxes, with 3 video cards :

Radeon 9250 AGP (have 2 of them) - with open source ATI driver
Geforce 6200 PCIE - with nouveau driver

In all cases I connect 2 LCDs. one 1440x900 or 1680x1050 to DVI and one 1280x1024 to VGA (all the cards have DVI and VGA out). The LCDs are the same ones tested with all cards :

1440x900 : Benq FP-92W
1680x1050 : Teac T2005L15 (identified as KTC2002 in xorg)
1280x1024 : Proview PQ-721KP

Tried on different boxes runnning Arch linux, different kernel / x / drivers / kde versions

Problem is - in all those setups, one monitor allways randomly blanks for a split second and comes back (incl. switching of the backlight, and displaying the "Source : VGA" or "Source : DVI" title as if it was switched off and on)

This happens randomly, but (more pronounced with the ATI cards) related to me clicking on stuff or the display changing (even if the changes are on the second screen)

With the Radeons only the monitor connected to DVI blanks. And the 2 radeons do it in different frequency, one is more often and one less

With the Geforce only the monitor connected to VGA blanks

When I test with 1 monitor (other one disabled in xorg) : Radeons sometimes still do that to DVI monitor but rare (much less than with VGA connected) (VGA monitor never blanks). Geforce does not do it at all and has problem only when 2 monitors are connected

I first thought its a hardware issue (the cards are from junk), but it happens the same with totally different hardware (exceps using same monitors) so i no longer think it is

There is nothing interesting in Xorg.0.log

I have the nVidia GeForce 8500 GT 512MB graphics card, I put it in my system to get a speed boost and for a dual monitor setup, I don't have the proprietary drivers installed I tried installing them, and when I did it asked for reboot, so I did, and when it came back up only one monitor was in use, and it was running very very sluggish, so I opened up the Monitors from the settings and it said to use nVidia's thing, so when I did, I enabled the second monitor, and hit apply, and it asked for a restart of Xorg, doing that came back telling me that no monitors were find, and a reboot brings me straight to tty1... I tried both the recent version and the older one, both did the same thing, I really wanna get my Compiz effects back. is there a way to get this working?

SUSE :: Nvidia Drivers And Dual Monitor Setup - Message Undefined Video Mode 31a
