I have been struggling for the last couple of days to figure out why my thunderbolt ports (on the left side of the XPS 13) stopped working on Ubuntu 18.04. The right side USB port works well and charging works on all the ports. Also, because I have a dual boot with Windows 10, I checked if I had the same issues and, indeed, the USB ports don't work on Windows. By USB ports not working I mean that neither ethernet, HDMI, external memory nor USB hub are recognized.

I don't know if it is a coincidence but it happened after I tried to find a way to transfer file to my android device. Following this post (Trying to install android-file-transfer Ubuntu 18.04 Bionic) I did the following

sudo add-apt-repository "deb http://ppa.launchpad.net/samoilov-lex/aftl-stable/ubuntu artful main"
sudo apt install android-file-transfer
sudo apt install libmtp-common mtp-tools libmtp-dev libmtp-runtime libmtp9

Here are the things I noticed so far

  • Windows can crash when I plugin a device on the left side (but not always) with a blue screen and a forced reboot
  • When it does not crash, Windows shows an error "device not recognized"
  • Ubuntu does absolutely nothing when I plugin a device on the left side
  • Wifi/bluetooth work fine on both Ubuntu and Windows

I've been trying to solve that non-working USB port issue for a while now and here are the steps I followed:

I run out of ideas so if anyone has a solution please feel free to reply. Thank you a lot.

Here are some kernel errors. Notably the "Cannot enable. Maybe the USB cable is bad?" that happends any time I connect a USB device on one of the left USB port.

I recently upgraded to ubuntu 18.04 but I'm facing issues with the wired connection. First off, I must say that the wifi connection is working fine.

When I start my computed I don't even get the wired network icon. Going into the settings/Network parameters, I don't see anything about wired connection (only VPN and proxy).

Thus I tried to understand what was happening and I used a couple of different commands:

~$ lshw -C network 
WARNING: you should run this program as super-user.
*-network

   configuration: autonegotiation=on broadcast=yes driver=r8152 driverversion=v1.09.9 duplex=full link=no multicast=yes port=MII speed=1Gbit/s

Then I decided to enable the ethernet interface as follows

sudo ip link set enx3c18a070d46d up

The result of the "lshw" command does not show DISABLED anymore. The wired connection icon came back but still no internet connection and now showed the following message

Wired unmanaged

I would be very interested if any of you have an idea about how to solve this problem.

Thank you and have a good day.

Finally, here are the results of a couple of commands (note that ifconfig is obsolete on ubuntu 18.04)
