Title: Thunderbolt display not detected Status in linux package in Ubuntu: Confirmed Bug description: I am using a Dell XPS 13 (9370) connected to a Caldigit TS3 Plus thunderbolt dock. On this dock I have two monitors connected. One is connected to the display port of the dock, the second one is connected to an USB-C Thunderbolt port using an USB-C to mini DP adapter. The second monitor is only detected, when I _first_ plug in the adapter and _then_ plug in the the cable to the adapter. This also only works when the system has booted _and_ I am logged in. I already disabled thunderbolt security completely in UEFI. Once the monitor has been detected it is also working during boot, when I restart the system. --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/pcmC0D0p: max 1628 F...m pulseaudio /dev/snd/controlC0: max 1628 F.... pulseaudio /dev/snd/controlC1: max 1628 F.... pulseaudio CurrentDesktop: X-Cinnamon DistroRelease: Linux Mint 19.1 HibernationDevice: RESUME=UUID=e6ab437d-a79f-412f-bed4-1a80bbde0736 InstallationDate: Installed on 2019-01-05 (47 days ago) InstallationMedia: Linux Mint 19.1 "Tessa" - Release amd64 20181217 MachineType: Dell Inc.
