I have a Ubuntu machine that I use as a Plex and data server. There is no monitor connected to it. This wasn't a problem with Ubuntu 16.04, but now, with 18.04, it is and it shows a black screen whenever I connect using VNC.

I've already created the virtual display using the answer to this question: https://unix.stackexchange.com/quest...output-to-xorg

Then I made a script that's executed bij Startup Applications:

#! /bin/bash

/usr/bin/xrandr -d :0 --output VIRTUAL1 --primary --auto

/usr/bin/xrandr --newmode "1600x900_60.00" 118.25 1600 1696 1856 2112 900$

/usr/bin/xrandr --addmode VIRTUAL1 "1600x900_60.00"

After this, it still shows a black screen when I connect using VNC. BUT, when I run this with SSH:

$ export DISPLAY=:0



$ xrandr

After that, I can see my desktop in VNC... Any ideas on how to fix this? Also, when I see my desktop after all this, the dock is missing and all the icons are in the same spot.

[EDIT]
Adding the line /usr/bin/xrandr at the end of my script made sure that VIRTUAL1 is active at reboot.

Dock is still missing though.

To conclude: this is how I solved it:

I've created the virtual display using the answer to this question: https://unix.stackexchange.com/questions/378373/add-virtual-output-to-xorg

Create a 20-intel.conf file:

sudo vi /usr/share/X11/xorg.conf.d/20-intel.conf

Add the following configuration information into the file:

Section "Device"

    Identifier "intelgpu0"

    Driver "intel"

    Option "VirtualHeads" "2"

EndSection

This tells the Intel GPU to create 2 virtual displays. You can change
the number of VirtualHeads to your needs.

Then I made a shell script (don't forget to set executable) and put that in Startup Applications:

#! /bin/bash



/usr/bin/xrandr -d :0 --output VIRTUAL1 --primary --auto

/usr/bin/xrandr --newmode "1600x900_60.00" 118.25 1600 1696 1856 2112 900$

/usr/bin/xrandr --addmode VIRTUAL1 "1600x900_60.00"

/usr/bin/xrandr

That way, VIRTUAL1 is set as output and connected. At boot, a new mode (found using "cvt 1600 900") is being created and appointed to VIRTUAL1.

Only issue with this is: dock is missing at reboot... Haven't solved that yet.
