I have a work computer with two 4k monitors and one 2k. I currently have to use Wayland with Ubuntu to get all the monitors to work. With Xorg I could only ever use two of the monitors. Not an expert with xrandr yet.

Is there a way to use all three monitors with Elementary OS? The video card is an Intel HD 630.

thank you

  • Not an answer but this might help: Try with the Live version of elementary OS, maybe there's a solution trying settings. The good thing is if you break something just reboot and try again. – Sebastian Dec 31 '18 at 14:17
  • Yeah, tried that. I end up with a partial view of the desktop in the upper left 1/5 of a corner on the main 4k screen. If I go into setting I do see all three monitors detected correctly. When I was playing with this on Ubuntu Xorg, I was seeing the same issue but the login screen spanned all three monitors correctly. Problem only occurred after login. – TheFlakes Dec 31 '18 at 15:15
  • check this.... might help elementaryos.stackexchange.com/a/17744/14940 – Sebastian Dec 31 '18 at 15:22
  • Thanks, but, that's a different issue I opened and found the answer to when trying to get one 4k screen, my laptop, to scale the way I wanted it to. – TheFlakes Dec 31 '18 at 15:25

Was able to get the multip display with two 4k and one 2k monitor to work by:

1. sudo add-apt-repository ppa:ubuntu-x-swat/updates
2. sudo apt-get dist-upgrade

This will upgrade Mesa to the latest version.

Since I was using an Intel HD 630 GPU I also did the below:

In /usr/share/X11/xorg.conf.d create the file 20-intel.conf with the below contents.

 Section "Device"
  Identifier  "Intel Graphics"
  Driver      "intel"

Not completely sure if the 20-intel.conf file is needed. But my multi-hdpi monitor setup is now working perfectly.

  • The 20-intel.conf is required for all this to work on my desktop. – TheFlakes Jan 10 at 19:52
