I'm setting up Ubuntu on a new Alienware R3 15. I have it dual booting with Windows 10. I also have a Thunderbolt display (Thunderbolt 2). I recently bought an adaptor so that that I can plug the Thunderbolt display into the Thunderbolt 3 port on the Laptop.
When I log into Windows the display is automatically recognised and works as expected. On Ubuntu the splash / load screen flashes for a second or two on the Thunderbolt display, then disappears. Then I just have the laptop screen working by the time the login screen loads. Once logged in, the displays dialog does not recognise the Thunderbolt monitor, only the laptop's screen. I've tried rebooting the machine as I understand hot plugging could be an issue. I had the same outcome after a reboot.
Any tricks to getting this to work? I'm using 16.04.2 LTS 64 bit with Gnome (3.18.5), I have a GeForce GTX 1070/PCIe/SSE2 card and the proprietary Nvidia 375.39 driver installed and selected. Again, no problems in Windows on the same machine.
Below is the output from running lspci
. From the directory here I believe Intel Corporation Device 15d9
maps to JHL6340 Thunderbolt 3 NHI (C step) [Alpine Ridge 2C 2016]

Nice instructions. You should submit this as a bug also; perhaps, then, someone will automate these steps so everyone who tries out their MAC display on Ubuntu won't have to go through the trouble you did. – LonnieBest – 2018-05-14T09:37:09.283
What adapter did you get? Please post here.
– LonnieBest – 2018-05-15T03:20:41.857@LonnieBest did anyone report this as a bug in the end? Here I am a year and some change later and this is still not plug and play on Ubuntu. I still have to try these steps manually, but I have to keep switching from an HDMI source and back to test. I would personally love to know to which agency to report the issue—is this an Ubuntu issue, Linux issue, USB-C/Thunderbolt/Intel issue? – Scorpius – 2019-08-25T01:48:01.037
@Scorpius : You might explain this in a bug report here. It is tricky, because Ubuntu actually has no problem running the Monitor, when you install Ubuntu onto a MAC mini. Yet, on non-mac-hardware, the adapters I've tried don't even know how to turn the Monitor on (it seem). This wonderful monitor doesn't even have a power button!
– LonnieBest – 2019-08-26T15:55:37.060@LonnieBest - are you saying you installed Ubuntu on a Mac Mini and the thunderbolt display was detected and used automatically? Which version Mac Mini hardware? Which version Ubuntu? I'm trying (and failing) to get the TB display to work from my late 2013 MBP... (the display's USB components are working, but no picture. :( – JVMATL – 2019-11-28T00:06:49.513
@JVMATL : Yes, that's what I'm saying. The Mac Mini I did it on seems to be about the same year as yours, but I can't verify it right now where I'm at. I've accomplished this on Ubuntu 16.04 and 18.04; the monitor turns on and just works and looks GREAT! I also installed a Samsung SSD into it and it runs fast. Be careful going inside of the Mac Mini, I bent the fan housing and had to order a new one, also, you'll need a mac screw driver kit to accomplish any upgrades. – LonnieBest – 2019-11-29T08:20:43.717
