Ubuntu

No external display with USB-C to HDMI/VGA Dell XPS 13 9350 and Ubuntu 16.04

Asked by pamzilla

Ubuntu doesn't see any external monitor connected with the USB-C adapters for video that came with the computer, tried both HDMI and VGA adapter, different displays (that do work with other PCs). The display manager in the system settings does not see any displays, and I can't change resolution either, Scaling tool works quite ok though.

I installed the displaylink 1.0.335 and the Intel graphics drivers earlier (skldmcver 123, intel linux graphics installer v 1.2.1-0intel2) but it doesn't help. I'm running 16.04 with 4.3.0_5 generic. None of these proprietary drivers show up , only "using processor microcode firmware for intel-cpus from intel micropprocessors".
I checked the BIOS, everything is enabled there, USB-C is enabled without security, tried with display only and security as well (ask user) with no improvement.

I'm running the latest BIOS from dell, v 1.1.7

If USB-C doesn't work yet, do you know if a USB 3/2 display adapter works? If so, which? I have only one USB-C slot and two USB-3 slots...

Many thanks!

Here's the output from lsusb and lshw.

I do not see a driver loaded for your graphics card ("*-display UNCLAIMED"), but I am unable to give any recommendations how to help with that.

Maybe someone else has an idea?

The Dell DA200 USB-C to HDMI/VGA/Ethernet/USB3 dongle does not work (displays no HDMI or VGA output) and actually freezes this system if an HDMI display is connected.

I can report that with my XPS 13 9350, running ubuntu 16.04 with kernel 4.4.0-28-generic, I am able to use the Kanex USB-C to VGA adapter with seemingly no problems. I had it plugged in when I turned on the computer, and it worked as soon as the desktop appeared. I hot-unplugged, then rebooted the laptop and tried hot-plugging, and it also seems to work repeatedly on plug-unplug-plug. I left it running for about ten minutes with no issues. Further field testing will take place shortly at a conference where I am giving a talk.

The Kanex part number seems to be KU3CVGA.

#14 Brian, are you using DA200 adapter by Dell? I can not get HDMI working on any resolution above 1440x900 pixels.
The kernel just crashes when trying to switch to something higher (like 1920x1080)

I have the same problem with the same hardware of pamzilla. I have updated the kernel to 4.7. with ubuntu 16.04

Linux ultrabook 4.7.0-040700-generic #201608021801 SMP Tue Aug 2 22:03:09 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

The ultrabook doesn't detect the second screen always, neither VGA or HDMI. The resolution by default of ultrabook is 3200x1800 but the apparence in the screem is like a 2560x 1440.

I am desperate. I have tried all I can imagine and nothing works for me.

In the last try I get the following output with dmesg when I plug the adapter on USB-C

I am using DELL XPS 13 9360, with USB-C adapter DA200 provided by DELL.
For me VGA works but my screen display a message like 'not HDMI signal received'.

I contacted DELL support, they requested i install the following driver [1], but it does not work more.

DELL support suggested that it can be intel graphics driver issue.

So what i did is :
echo "deb https://download.01.org/gfx/ubuntu/16.04/main xenial main #Intel Graphics drivers" > /etc/apt/sources.list.d/intellinuxgraphics.list
apt-get update
apt-get install intel-graphics-update-tool
intel-graphics-update-tool

But it does not lloks to change something.
