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, ...

Update of kernel to 4.4.8-wily will solve the problem. It works fine with Intel® HD Graphics 520, so I assume that it should help to all Skylake graphics cards. Instalation instructions here: http://linuxdaddy.com/blog/install-kernel-4-4-on-ubuntu/

The cursor speed scales with the display size, I think. I have dual monitors, but I don't really notice it. The computer monitor's aspect ratio is most likely different than the external display's aspect ratio. If so, there's your problem, and the only way to solve it is to get a display that matches the laptop display's aspect ratio, or make the resolution ...

Unity uses Compiz as composing manager, and that has all sorts of plugins for this sort of stuff. To make it easy and long story short without messing in command line , install Compiz Config Settings Manager ( with sudo apt-get install compizconfig-settings-manager or via Software Center ) , and look for Place Windows , ensure it's checked Under that ...

I've got a 4k display and a fullhd display. After sleep, the 4k display refuses to start, except if my mouse is far right on the fullhd display. If I disable the second monitor, apply settings and enable it again everything works like in 15.10. I've got an integrated Intel graphics card (sky lake).

I had exactly the same issue with my TV on second HDMI port of my Intel HD integrated graphics on Ubuntu 14.04 even 16.04. Sometimes TV got detected, sometimes not. It was absolutely same under Windows where helped to disable graphic adapter in device manager for a while and re-enable it and TV on second HDMI got magically detected. Finally I found a ...

Yes, and no. To make the basic system see one large screen, you will have to enable Xinerama (the NVidia documentation is incorrect in this sense, and states you must disable it). However, even with Xinerama enabled and basic functionality working correctly, you will still have issues with some things not wanting to work properly, such as attempting to ...

Solution For The Tearing Problem As /u/ropid suggested, I tried adding this __GL_YIELD="USLEEP" KWIN_TRIPLE_BUFFER=0 KWIN_USE_BUFFER_AGE=0 to /etc/environment. This fixed the tearing issue for me. Solution For The Encryption Problem I found this link, which suggested to do the following: sudo nano /etc/default/grub Then replace ...

whatever happened since this post first appeared and after making the obvious changes in settings, it now looks as if plugging a mouse and keyboard in is enough to wake the external monitor up whilst keeping the laptop lid closed and its screen off.

The the timeout values for all power saving features (Standby, Suspend and Off) are set to 0, which disables them. You can set the timeouts with the xset command: xset dpms [standby [suspend [off]]] Where standby, suspend and off are the timeout values in seconds. For most modern displays there is (at least in my experience) no real difference between ...

The behaviour you describe (opening the window on the current screen) should be the default behaviour, On my 14.04 it is like that. Due to minor incompatibilities with some graphics driver/GPU combinations, "peculiarities" might occur in some cases. If there is no "clean" option available (fix), you can use the workaround below. It exists of a background ...

Not 16.04 specific The issue you are facing is not exclusive to 16.04, it happens on many Ubuntu versions. How to solve Reading your output of xrandr, and assuming I made no typo, the following command should arrange your screens the way you set it up: xrandr --output DP2-2 --auto --pos 0x0 --output DP2-1 --auto --pos 2560x0 --output eDP1 --auto --pos ...

Today I managed to install 3 screens (2 monitors + laptop screen0 by simply removing the bumblebee package and installing fresh version of Nvidia drivers 352.63 sudo apt-get install nvidia-352 One important thing: After reboot go to Display panel and line all monitors up so that the laptop is on left end (maybe it also works on the right end), anyway in ...

I suspect the issue is the result of a bug, since I cannot find another cause. At least as a workaround the background script below could be used. The script does the job on my system, but you'll have to try and see. If it doesn't work on your system, we can switch to xrandr to specifically switch of per monitor, but this is the simplest option. Resources? ...

While as of right now there's no simple menu for that, one can bind a shortcut to open the display settings. To do so , go to System Settings -> Keyboard -> Shortcuts -> Custom. Press + (plus) button to create new shortcut. You will see a popup asking for Name and Command. Name the new shortcut and set unity-control-center display as the command. Click ...

I had the same issue. I have tried all the driver changes posted here and elsewhere. Non of any of that helped. So, I went back to an old trick someone showed me once. When all else fails: Shut your pc down. Unplug your pc. remove the pc's battery. Wait 30 minutes then reverse what you did. Shazaam! It worked! This seems to be a fix to most of my pc ...

This isn't really an answer, but it's a workaround: when I'm in this state, toggling between console mode and back to graphical mode (ctrl-alt-f1 and ctrl-alt-f7) kicks the monitor out of sleep and fixes the problem.

I'm using Ubuntu 14.04 and a Sanyo TV. After an update or something, the top panel moved off the top of the mirrored display, so I could only see it on the laptop monitor. The fix for me was to adjust the 'vertical pos' from 50 to 25 in the TV picture menu, when you're in the D-SUB input source mode of the TV (because the 'screen' sub-menu is available ...

Go to Settings > Display and check the box that says "Configure new displays when connected". Now when you plug a new monitor in, it should pop up a dialog box for selecting the display mode. If this does not work, check to make sure that you are using the best driver for your graphics card. (Settings > Additional Drivers)

Okay, apparently my problem has been magically solved. I apt-get'ted plasma-desktop and tried that, just to see if that would allow me to maximize windows on both monitors. Nope. I could not even drag windows to my left monitor. It would split-screen maximize the window on the right monitor instead. Not feeling like fiddling with an unfamiliar desktop ...
