Ubuntu 18.04.1 LTS issue with Dell Thunderbolt 3 Dock after update
Solution 1
I am posting to confirm I had this same issue after a kernel update yesterday.
Same symptoms, wouldn't boot with the dock plugged in. Plugging the dock in after laptop boots standalone caused the laptop screen to go black and everything lock up.
Tried with everything disconnected from the dock except power (as I thought the laptop was having issues going to the dual monitors).
Had to roll back from linux-image-4.15.0-44-generic (4.15.0-44.47) to linux-image-4.15.0-43-generic (4.15.0-43.46) and the Dell dock + monitor is working for me now.
Solution
Press ESC on boot (UEFI) or Left Shift if BIOS, then select advanced boot options. I went to older kernel (-43). Confirmed issue wasn't occurring for me on -43, so removed -44.
sudo apt-get purge linux-image-4.15.0-44-generic
Solution 2
Upgrading kernel to 4.15.0-45 (available today on Ubuntu repositories) solved if for me! At last!
Solution 3
sudo apt remove linux-image-4.15.0-44-generic linux-headers-4.15.0-44-generic
This helped me. Ubuntu 18.04. Dell XPS 9570 + thunderbolt tb16

I have been using Ubuntu 18.04.1 LTS on a Dell Precision 5510 laptop with a Dell Thunderbolt 3 Dock, model TB16, for over two months with no issues. The system is regularly updated with the latest updates.
January 29th 2019, a notification for a new update appeared :
- Several unused kernel files to be deleted
- (update for Oracle's Virtual Box, seems very irrelevant)
I proceeded to install. However after rebooting, reaching the login screen and entering my password, I only had black screens and a completely unresponsive system.
After several reboots and attempts to diagnose the problem, only when I rebooted the system with the Dell Thunderbolt 3 Dock unplugged that the system successfully booted and displayed the desktop, menu bar...etc. Even then, when I re-plugged the dock, the system became unresponsive with a black screen.
I am currently looking into restoring the pre-update kernel using GRUB.
I'm interested to know if anyone, with a relatively similar setup, is experiencing this issue. Any other insights or ideas that could help are welcome.
Update :
Another report on this issue found (2 posts by the same author), it seems to affect only Dell docks but it is probably not restricted to Dell machines:
https://answers.launchpad.net/ubuntu/+question/678174
For now the issue has been resolved by restoring 4.15.0-43-generic using GRUB. I am holding from updating Ubuntu until the bug gets fixed.

hantaho over 5 yearsI have the same problem with a Lenovo T460s and a LENOVO® ThinkPad® Ultra Dock 90W. So the problem is neither Dell specific nor depends on the Thunderbolt dock, but seems to be a more general one. I had to downgrade to Kernel 14.15.0.43 as Kernel 14.15.0.44 seems to be buggy.

Covich over 5 yearsSame problem for me (ThinkPad X1 Carbon 5th + Dock Thunderbolt 3) Seems to work again after a downgrade to kernel 4.15.0-43

Nijin22 over 5 yearsThere are similar issues on my desktop + 2 monitors setup (both display port). Seems it is not necessary related to a dock, but more to external graphics. Downgrading the kernel works as a workaround.

Benjamin Barrois over 5 yearsSame problem here with XPS 13 9360. I can use the dock only if I deactivate Thunderbolt direct access in Ubuntu settings. And then I can have charge + screen but nothing else.

isherwood over 5 yearsI had to add
-f
to the purge command due to "not empty" errors. Thanks. -
isherwood over 5 yearsYou probably don't want to remove the currently active kernel, though. Reboot into -43 first.

L42 over 5 yearsI can confirm that updating the kernel solved the problem. First, do
uname -a
to verify that you have 4.15.0-44. Then, dosudo apt-get dist-upgrade
to update. After rebooting, I was able to use my dock as before.
