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'm having the same issue here with Ubuntu and it's flavors (Ubuntu Gnome and Kubuntu). I have an old notebook (1th gen intel i) with intel graphics integrated but never had this issue in the past nor with the 15.10 cicle. The problem only occur when a second display is attached to the machine.

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. As an alternative it is possible to add a signature to the driver. Getting the driver to work on the XPS13 is ...

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 ...

Upgraded my Lenovo W540 to Ubuntu 16.04 LTS and I now have 3 monitors connected on the UltraDock. Using VGA, DVI and DisplayPort connectors. All three show up in the normal Monitor Settings dialog. The Audio port on the UltraDock works as well where with 14.04 I plugged my speakers into the W540 each time. Using standard bios setup for video, I need to ...

I have this laptop and i use it with an external 4k screen connected via the thunderbolt(display port) socket. It works fine with both screens at 4k 60hz and i don't have an xorg.conf.

The Intel driver is in a state of junk when it comes to Broadwell/Linux, and Intel knows it. It is unclear what their priorities are. Ubuntu is only 1% of their market. bugs are here: https://bugs.freedesktop.org search for like DRM Intel. They use kernel version. GNOME is in a sad state, too.

I appreciate this is an old question. You have no doubt long since resolved this issue. For anyone else who find this, I resolved this issue by heading to /etc/X11/xorg.conf and modifying to monitor HorizSync and VertRefresh values. I can't remember what they were but this is how the monitor section now appears. Section "Monitor" .... HorizSync ...

Background script to check for new screens Once per 5 seconds, the background script below looks for new screens to be connected.

I was experiencing exactly the same problem with my Zenbook UX305UA...until today. This was a very annoying problem since it only has mini-HDMI output. The external monitor/tv/projector was only working if the laptop was turned on with the cable already plugged, but was freezing if connecting the cable once the system was running. Only hard power off could ...

I created a script for one of my monitors and run it as I connect the monitor. So you can make similar different scripts for your different monitor types and run each as per requirement. #!/bin/bash sudo xrandr --addmode VGA-0 1440x900_60.00 sudo xrandr --newmode Modeline "1440x900_60.00" 106.47 1440 1520 1672 1904 900 901 904 932 -HSync +Vsync ...

If you use optimus graphics, I suppose it depends on whether the display port is going through your intel graphics or on your nvidia graphics. Does your external monitor work when you switch to the intel profile in nvidia-settings? if so, then the display port most probably runs through your intel graphics. I am not sure whether bumblebee and primus ...

Found the culprit. Had these 2 files: /etc/modprobe.d/nvidia-352_hybrid.conf /etc/modprobe.d/nvidia-346_hybrid.conf Both of them had blacklist nouveau and alias nouveau off which was preventing the nouveau driver from loading. With these 2 removed I was able to see all outputs and configure all 3 monitors.

I am not 100% sure this will fix your issue, but you should check out this ubuntu documentation regarding hybrid graphics and how to use switcheroo to activate the different cards. It solved my issue when trying to use my hybrid ati Sony laptop that kept losing the Intel drivers and not the ati. Hope it helps!

There was something stuck in the VGA port on my laptop, though it was almost impossible to see. I now have a laptop case to avoid the same problem in the future.

The problem in your case is that when you are connecting the external monitor, it is by default being taken as the primary screen which is in left and you have to move your cursor to right of your extended monitor to get it on the laptop screen. This is problem is easily solved when you are using the light environments like LXDE. They have it on their ...

So after a lot of Google, trial and error and the help of others on this forum I was able to get all four monitors working relatively reliably.

After reboot all ...

From my experience with XFCE, the system tends to use the leftmost monitor for icons and panel placement. Setting the monitor you want to use, as primary also tells the system to prefer it. These should also apply to KDE I guess.

For one, you'll want the proprietary Nvidia drivers like Frank mentioned. Another thing which should help: from what you said it sounds like you have one monitor running off of your CPU (through the mother board), and one running off of the GPU. I would recommend running both monitors off of your Nvidia GPU. The 970 can definitely support it, and it's ...

First save any work in case your screen turns off and won't turn on without restarting. What I am going to suggest is temporary to begin with; you can make it permanent if it works. Go to the terminal and run cvt 1920 1080 60. This will output a string of text or two. The last one should start with the word Modeline. Copy from the first text after ...

If your screen is switching off it might be struggling to keep sync with the output signal. There are two main reasons for this , the first is refresh rates being too high for the screen to keep up with and the second is the cables are not good enough. There is an outside chance your graphics card can't cope with multiple screens but most are powerful ...

You can either set it in some GUI app but I'm not sure about the level of customization or using a command-line tool xrandr: http://manpages.ubuntu.com/manpages/wily/man1/xrandr.1.html https://wiki.ubuntu.com/X/Config/Resolution

Based on the xrandr output you posted, it looks like your card or driver does not support the DVI output. Try using one of the other outputs, and make a simple xrandr script to configure your monitors at login. My login script is just one line like this: xrandr --output VGA-0 --left-of DVI-0 --primary I called it lxde-setup.sh and added it to the ...

The solution is to move the mouse pointer between the two monitors repeatedly till this weird looking pointer is gone . Usually, within 2-6 quick transitions of mouse pointer between the monitor fixes it. And, no need to restart the computer. It is in fact related to the buggy AMD driver. PS- Some nVidia drivers also have shown such behavior. This behavior ...

To expound further on one aspect of @Jacob's answer: The monitor.xml file does override any similar left-to-right ordering that is set up in the nVidia Settings.

So, personally I don't own this laptop, however I spent some time looking around.

This seems to be ...

As far as you speakers go on your laptop, make sure you have not got a hardware mute button that is disabling them. Then check any software mute that is enabled.

It sounds like something incompatible with 16.04 in your home directory. You can check this by working with the console and creating a clean home directory.

I had this problem on 14.04 with a similar setup. I also, at some point, had a problem of text editing delay from one of my monitors. I had two video cards: one with 1 DVI port, and the other with both a VGA and DVI port. In the end, I determined my problem was that I was mixing video cards: I was using two DVI ports from two different cards. By instead ...

I have exactly the same problem. I have two monitors, one on DVI, one on VGA. Everything worked fine with Kubuntu 15.10. Now, with 16.04, you can see that during the boot up, the VGA monitor stays black, but Ubuntu thinks it activated it. Also for me, the only workaround is to deactivate the second screen in the system settings and to re-activate it. Then, ...
