I'm running Elementary Os Loki 0.4.1. I wanna connect another monitor to my laptop, but my OS doesn't recognize it. In settings it doesn't even detect that I have another monitor connected (via HDMI).

I've trying shut down the system and getting it back up again, it didn't work. I'm up to date with updates and upgrades too.

I don't know what else to try. If someone could help me, that'll be awesome :)

UPDATE I've been looking and found this: Laptop + HDMI external monitor issue? I tried it , but I don't have the ~/.config/monitors.xml file. I've search everywhere, even within hidden folder, just nothing.

In my terminal I put tho command lspci | grep VGA and the output was:

00:02.0 VGA compatible controller: Intel Corporation Skylake Integrated Graphics (rev 06)

I tried the command lspci -nn | grep '\[03' too, and the output was:

00:02.0 VGA compatible controller [0300]: Intel Corporation Skylake Integrated Graphics [8086:191b] (rev 06)

01:00.0 3D controller [0302]: NVIDIA Corporation GM206M [GeForce GTX 965M] [10de:1427] (rev a1)

I don't know If you are still around. I never done this but I just gathered info I believe might help you


First

You need to install Nvidia drivers

Install:

$ sudo apt install software-properties-gtk software-properties-common

Then use the command:

$ sudo ubuntu-drivers list

You should get something like this (probably different version numbers):

nvidia-304
nvidia-340
intel-microcode
nvidia-367

Install nvidia-367 (or the version you want, and could be different)

$ sudo apt install nvidia-367 nvidia-settings

Final step

Open:

$ software-properties-gtk

Choose the tab Additional Drivers

Wait for the loading list, and then you should see the recently installed driver.

Select it and reboot

enter image description here

Now, after reboot, open $ nvidia-settings

Look after an entry named PRIME Profiles, select it and then choose the NVIDIA GPU

enter image description here

Reboot again

Done


Additional Info

You can also check and change PRIME using a command

Install:

$ sudo apt install nvidia-prime

To check

$ sudo prime-select query

To select Intel GPU as PRIME

$ sudo prime-select intel

To select NVIDIA GPU as PRIME

$ sudo prime-select nvidia

    Hello, I'm sorry for the bit delay. I haven't used linux in a while. Thank you very much for your answer. It didn't work exactly, but it worked so that I could find the drivers I needed. When I went to the Software&Updates >Additional Drivers, I had one of Nvidia, but didn't work. I also had one called "X.Org X Server (open source", I tried it and it worked. Thank you very much for the help. Have a really nice day and Merry Christmas and Happy New Year ;) – Mariana Leites Dec 22 '18 at 21:37

I have such a problem when my video driver is set to use the internal Intel video card instead of the Nvidia one, and this is because on my hp laptop the HDMI port is on the Nvidia graphics card and there is no access to the internal Intel one. Check out if your configuration is similar

  • I believe I have that same problem, and I'm still new to the elementary, so could you tell me where I can find those configurations, please? – Mariana Leites Mar 15 '18 at 23:56
  • ok, can you use the Terminal application, copy and paste there the following code lspci | grep VGA , press Enter and leave a comment with the output? – Bo rislav Mar 16 '18 at 12:13
  • I'm so sorry for the delay, but i didn't had my computer with me until now The output of the command is 00:02.0 VGA compatible controller: Intel Corporation Skylake Integrated Graphics (rev 06) – Mariana Leites Apr 30 '18 at 13:49

If you are still having a problem with display drivers you can try: sudo ubuntu-drivers autoinstall

Or if there are any other problems with drivers or packages during the boot run: sudo dpkg --configure -a
