this link should solve your problem: https://help.ubuntu.com/lts/ubuntu-help/display-dual-monitors.html Basically, it's adjustable through the system settings -> display. set the launcher to be shown only on one monitor, and then it becomes the primary monitor. afterwards, you can show launcher on both monitors without changing the primary monitor.

I have a similar setup, different gpu version and using VGA and DVI. I am facing the same problem from the most recent update. I previously had both monitors working with the 4.4.0.22 kernel. During startup see if there is a new kernel installed and try booting into an older one. How to change kernel at boot edit: also try this Dell 3543 Kubuntu 16.04 can&...

x2go also uses NX technology and has support for Xinerama. This should solve your problem.

No. Note that as of date of last testing (2014, xcalib version 0.8) xcalib has not been able to invert the colors on all monitors in a multi-monitor setup, because all monitors are presented by the X11 server as a single screen. Thus this limitation is coming from the X11 server. xrandr-invert-colors does not have this limitation, because it ...

I have the same laptop as well with 3 monitors (including the build-in) using the nouveau drivers, nvidia-361.41 that comes with ubuntu 16.04 does seems working pretty well especially with the mini display port. Which display drivers are you using?. Have you try the HDMI port instead? Another solution may try add a new mode by yourself by using xrandr. ...

I was able to solve this using something similar to the second example posted on the Arch Wiki for NVidia cards - TwinView. Each monitor is plugged into a separate graphics card and I've enabled SLI Mosaic mode. I've also forced the refresh rates to 60 Hz for the moment, but may uncomment this and use a range to see if that works. I created a new file in /...

When rotating the screens the NVDIA driver does not know that he has to stitch the 3 screens together. You will see a small black spance when opening the display manager. Just resize, move so the 3 monitors are really side by side. I did not saw that because I ve changed screen orientation in Preferences and not within the NVDIA interface.

The solution was to create a guest account, and play the video from this account.

You can use gsettings for enabling and disabling monitor from going to sleep: Disable turning off screen gsettings set org.gnome.desktop.session idle-delay 0 Enable turning off screen with 5 min delay gsettings set org.gnome.desktop.session idle-delay 300

Just found out how to fix it, at least until I reboot, if anyone knows how to make this permanent let me know, for now I run a script on startup. xrandr --output HDMI-0 --set underscan on

Go to the file manager of your system and and navigate to the Desktop folder, then drag-n'-drop the icons from there onto your actual desktop.

I don't have a similar setup, but would urge You to try again. Proprietary nvidia drivers are released quite regularly, so there is a good chance that the Your original issue may have been fixed by now. Link to most recently released nvidia driver If simply using the "Try Ubuntu" option on a Live CD/USB does not work (using the bundled open source nouveau ...

So I googled around a little more and after trying a few things I found that xrandr doesn't quite work well nvidia proprietary drivers, so I had to use : sudo nvidia-xconfig to generate a xorg.conf in /etc/X11/xorg.conf I then googled around for the HorizSync and VertRefresh values for the monitor in question which I found to be: HorizSync 30 - 83 ...

This morning I decided to try it again. And. It. Just. Worked. I have no freaking idea why it works now. I tried it several times over the past weeks and today suddenly it worked. Perhaps there was an update that fixed my problem? Whatever, I'm happy I have my big monitor back :)

Is it a laptop you're on? If so, sometimes there is a keyboard shortcut to switch between display ports. On my laptop it's FN(Located bottom left of keyboard) + F10. Whichever key it is will most likely have an icon on it of a monitor and laptop side by side with a line in between. Turns out it's FN+F7 according to the instructions of your laptop. http://...

I am also getting this issue with Intel integrated graphics on my Dell XPS 13 after upgrading to 16.04 LTS. Let's see if we can fix this together.

x240 and x250 no problem with 2 external monitors (keep in mind you do need the right docking station) and ubuntu 15.04, 15.10 and 16.04. I had problems with the set up for the x260. Even with a brand new docking station. Not sure if I had a Monday-machine or if the hardware was conflicting. I did not get it to work with ubuntu 15.10 and x260 and docking ...

I would approach the problem from a different perspective. Your xrandr obviously recognizes both screens, hence, you can use them by manually changing between them by using the command line. That is, of course, quite inconvenient. So you might want to install a program called disper and set it to a hotkey as explained in this answer. Shortly, just install ...

This might be because both of your monitors work in 60+ hrz range. Try using xrandr to manually set them both to, say, 50, or better 40, and see if it helps. Most of the laptop graphic cards do not support 120+ hrz frequency which you would need for two monitors both having 60+.

Yes, X can use multiple drivers. Yours is a very similar setup as what I have. I have an NVIDIA 9800 GT with two monitors connected and an 2nd generation intel card with a single monitor. I don't see any problems with your xorg.conf. I suspect that you will need to create an xorg.conf if only to tell X to use both nvidia and intel drivers. My xorg.conf ...

If you are running an Nvidia card (with Nvidia drivers), you can use their settings tools to set the primary monitor. The Nvidia drivers have more options than the native Ubuntu monitor configuration. Run the following command to start the Nvidia Settings Configuration sudo nvidia-settings If this command isn't found, this solution will not work until ...

Automatically move the launcher, depending on the active screen A possible solution is to automatically change the position of the launcher, depending on the current mouse-position: if it is on the left screen, move the launcher to left if it is on the right screen, move it to the bottom In the test I ran, it worked surprisingly smooth, and windows ...

I cannot see a mechanism to choose a different location for a single launcher (e.g Unity) on different monitors. Given the problem of real-estate (limited horizontal), I can see that placing a launcher at the bottom of the screen and auto-hiding it would be a solution. In Ubuntu 16.04 LTS, you can move the Launcher to the bottom, but I realise this ...

I got this from reddit user /u/ProblyAThrowawayAcct, the issue was my HDMI -> DVI cable was passive which caused it took take 2x my cards output bus. Replacing that with a VGA -> VGA w/ DVI adapter cable resolved the issue.

The usb c port is the weakest link here, I have a near identical setup on my m3800 but the display port is over thunderbolt and it works fine. One thing to check is that the monitor is in display port 1.2 mode or better. You could also try reducing the refresh by 1hz to 59khz to make it easier on the computer. You can generate modelines with CVT and apply ...

If I made no typo, the command: xrandr --output eDP1 --pos 0x0 --output DP1-3 --pos 1920x0 --rotate left --output HDMI1 --pos 3000x0 should set up the screens like in the image (please try first). To make it stick on next login, add to startup applications: /bin/bash -c "sleep 15 && xrandr --output eDP1 --pos 0x0 --output DP1-3 --pos 1920x0 --...

I think you are over thinking this. Record My Desktop has an option to "Select Window" before you start to record. Maximize the Record My Desktop Window on the monitor you wish to record, click the "Select Window" It will grab the whole screen. Then simply minimize Record My Desktop window used for selecting that monitor You can then move the Record My ...

I installed 16.04-LTS via the Ubuntu upgrade procedure, and it works fine. I installed the DisplayLink USB Graphics Software for Ubuntu, version 1.1.62. http://displaylink.org/forum/showthread.php?t=64503 I had to disable secureboot in the BIOS.

On newmode, 1280x1024_60.00 is enclosed in double quotes, whereas on addmode and output it isn't. Use double quotes on those two commands too. At least, this is the correct syntax. An additional problem is that you are trying to add a mode to a disconnected port "VGA-0 disconnected (normal left inverted right x axis y axis)" which won't work. The port ...

There was no real solution to this issue, I was required to use a DVI and Display Port adapter on the same graphic card to extend the two monitors.

To sort this issue (and the related issue in this question), I re-installed Ubuntu 14.04. When I did this, the open source graphics driver automatically recognised the dual monitors and the laptop has been working like a dream since. I guess the problem was with the proprietary AMD drivers which seem to be buggy as hell. Thanks to all for the assistance

For xfce4 users, it looks like the file ~/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml could have been modified for some reason. Deleting it solved my issue. It's not been generated again at logout/login so I don't know exactly what it is supposed to do. I also found that with other desktop environments there is a similar(?) ~/.config/monitors.xml ...
