I don't really know where to start looking to solve this problem. Searching the web didn't get me very far. I'm not using any special adapter, it's a straight HDMI cable. It's a fresh install of Ubuntu 14.04.3 (later also 15.10). The same monitor, cable and laptop work in Windows.

Curiously

if I unplug the monitor, then I run 

sudo apt-get install --reinstall ubuntu-desktop
sudo reboot now

the first time I login, and the first time i plug the cable in, the second screen works without problems (dmesg still complains about WARN_ON(!wm_changed), but no more i2c i2c-1: sendbytes: NAK bailout.). But as soon as the laptop turns off the screens (standby) or I reboot the machine or I unplug the cable, the second screen doesn't work anymore.

Also, if I reinstall ubuntu-desktop, but power off the laptop with the HDMI cable plugged in, this trick doesn't seem to work.

HW:

  • acer Aspire V 17 Nitro - Black Edition (Aspire VN7-792G)
  • GeForce GTX 960m / Intel Graphics
  • the second monitor is connected through the HDMI port

I'm using the proprietary nvidia driver found in the "Additional Drivers" app. But setting that to use the nouveau display driver doesn't help either.

Could someone please point me in a direction?

UPDATE: I've installed 15.10. Installed the "Intel Graphics for Linux" drivers. And it still doesn't work. But now when I click on "Detect Displays" in nvidia-settings, the application segfaults. Don't know if this has any relevance.

  • You could try going into the BIOS and setting the graphics mode to Intel-only or Nvidia-only. Also try updating the BIOS. – QwertyChouskie Feb 20 '16 at 23:09
  • @user4901968 Thanks for the idea. I've updated the bios to the latest version. Unfortunately that didn't change anything and the bios doesn't offer me an option to select a GPU – Roman Feb 22 '16 at 09:00
  • Can you try blacklisting i2c? See http://askubuntu.com/questions/110341/how-to-blacklist-kernel-modules – QwertyChouskie Feb 23 '16 at 02:14
  • uhm, lsmod doesn't show any i2c. – Roman Feb 23 '16 at 15:46

    Try going back to 14.04. Do not install any intel drivers that are not available from official repositories through apt-get. Do not configure you X server to use nvidia drivers - use intel drivers. Make sure your /etc/X11/xorg.conf does not contain any "Device" section with "nvidia". Then try again if the monitor works. – nsilent22 Feb 23 '16 at 20:03
  • Before you reinstall, try installing the latest version of the Intel drivers (a new version was just released). – QwertyChouskie Feb 24 '16 at 02:30
  • I've installed the newer intel graphics driver (1.4.0). This managed to break pretty much everything - could no longer login (xorg server crashed because no screen was found ).

    Then I've reinstalled ubuntu, leaving everything at his default (no nvidia, there is no xorg.conf, no intel graphics installer). This way the laptop monitor works (when I start with "nomodeset"), but plugging in the HDMI cable has absolutely no effect (not even error messages).

     – Roman Feb 24 '16 at 13:02
  • also, while using nouveau, compiz eats up like 350% CPU when I drag a window around – Roman Feb 25 '16 at 10:03
  • @Roman - do you have dual-boot installation with Windows together ? - acer nitro is a very special thingie ... probably the BIOS is not as good as BIOS of shuttle. – dschinn1001 Mar 19 '16 at 03:11
  • @dschinn1001 yes it's a dualboot. In the meantime I've "solved" the issue by giving the acer to the gf (she uses windows) and buying myself an asus. (had no problems with that one).

    So the only solutions seems to be: don't buy acer (the monitor wasn't the only issue, couldn't get the wifi working at all).

     – Roman Mar 20 '16 at 16:14
  • @Roman - the other possibility is, when you have a brandish new device (the most actual device from the market) then you should wait 6 to 9 months, - then this device is supported more than at beginning. In Linux is the rule that hardware (newest one) is supported after 3 to 12 months fully. Or you could test if Manjaro Linux is running with a device. I cannot comment about what is better than "acer" or than "asus", because I must not advertise here. ;-) – dschinn1001 Mar 29 '16 at 19:53

I would try following in case the installation is a bit overdone:

sudo apt-get install ppa-purge
sudo apt-get purge nvidia*
sudo ppa-purge ppa:xorg-edgers/ppa
sudo reboot

Back into terminal, simply try this only:

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update

then this here:

sudo apt-get install nvidia-358 nvidia-prime
sudo apt-get install --reinstall xserver-xorg
reboot

I would install ARandR and use that GUI instead of NVIDIA or others. It works fine for me to set and keep resolutions using multiple monitors on Ubuntu flavors of linux.

Open a terminal window and install: 

sudo apt-get update && sudo apt-get install arandr

Then to start using simply find arandr as an app listed in your applications menu. After installation, find it in the menu : 

System -> Preferences -> ARandR

Homepage of ARandR : http://christian.amsuess.com/tools/arandr/

All the best ..

    arandr doesn't see the other monitor, just like the default ubuntu display settings thingy – Roman Feb 24 '16 at 13:07

Could be driver or Xserver issue? Maybe try:

sudo apt-get remove purge nvidia*
sudo reboot

boot with nouveau drivers (in grub add 'nomodeset' to the end of the linux line)

sudo apt-get install nvidia-current nvidia-current-updates

^ Or replace 'current' with the driver version you're using (I think latest is 352?)

Use ctrl+alt+1-7 to open tty1-7

sudo apt-get install --reinstall xserver-xorg

sudo reboot

Don't add 'nomodeset' on this reboot

This may not fix it but I suppose you should make sure it's just not broken drivers

  • During the last days I've installed and reinstalled pretty much anything. Formatting the disk and reinstalling various Ubuntu versions. Reinstalling nvidia-anything and xserver-xorg did not help. Thanks anyway – Roman Feb 26 '16 at 16:42
  • Sorry it didn't work for you... It never hurts to check! @Roman – Gabriel Ruoff Feb 26 '16 at 19:33

Try the OEM driver, download it here. You will need to kill your graphical sessions, and login as root. you can do this, provided you have permission, by pressing ctrl+alt+F5 then login, and do: sudo -i Next, kill the sessions with kill -9 lightdm you may need to make the script you downloaded execute-able. you can do this with chmod +x <script-name> then, execute the driver install script. Follow the directions, and install the GPU drivers. once it completes, you can run lightdm or startx to see if the changes have improved your situation.

You can go to system-> properties-> displays

to see if your monitors are detected.

You may also want blacklist the Intel drivers, where you are trying to use the NVIDIA GPU instead.

  • Iv'e tried this before, but after installing the OEM drivers I can't get past the login screen (xorg, lightdm or whatever crashes). Did I miss something? – Roman Feb 26 '16 at 16:46

I had this problem in the past.

The only Kernel that I was able to get an external monitor working with (every time) on my V15 Nitro is 4.7.2.

I dug for days to try and get to the bottom of it. Don't even remember if it was trial and error or piecing together multiple sites or whatnot, but that's the only solution I've come across. Hope it helps.
