Black Screen with HP EliteBook X360 and HP USB-C Dock
 

I just installed Ubuntu 17.04 on my HP EliteBook X360. Still a lot of hardware not working (fingerprint sensor, IR camera. etc...) but, after installing the DisplayLink drivers 1.3.52, the HP USB-C Dock is recognised as a DisplayLink device AND my monitor (Benq BL2420T 2560x1440) is recognized and appears in the Displays control of Ubuntu.
The problem is that when the screens are configured as extensions, the monitor is simply black, no image....and when the screens are configured as mirror, I only see a frozen mouse pointer on the external monitor.
The laptop's display works ok.

Any clue?

Here is the Machine.log:

Attached are all the logs from the DisplayLink Linux Support Tool

I had this problem too, but fixed by doing the following:

1. Create a new file at `/etc/X11/xorg.conf.d/20-intel.conf`
2. Add the following content:
   
   Quote:

   Section "Device" Identifier "Intel Graphics" Driver "Intel" EndSection

3. Reboot

Hopefully this will work for you too.

Hi Dylanparry.
This totally did the trick!
Now the external screen work fine. I just had to adapt the path you specify as in my distro, xorg.conf.d is in /usr/share/X11/

Thanks a lot!

Excellent, glad it worked :)
