Update on the Thunderbolt Dock:
I risked installing the lastest kernel and by now EDID files seem to be parsed correct! I got my 2560x1600 running on 60 Hertz again (connected via Displayport). It's a real relief!
Code:
Linux workstation 4.6.0-040600rc6-generic #201605012031 SMP Mon May 2 00:33:26 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
All the other stuff is not working yet (ethernet, USB, additional thunderbolt plug)

Recently I was able to acquire a Dell Thunderbolt Dock TB15. As some of you already asked about it, here my brief status update:
System environment:
- Xubuntu 16.10
- 4.4.0-21-generic #37-Ubuntu SMP Mon Apr 18 18:33:37 UTC 2016 x86_64 x86_64 x86_64
- Dell Thunderbolt Dock TB15
Note:
- Once I unboxed my TB15 I recognized the plug was not marked with the usual USB 3.1 logos but rather with a Thunderbolt logo. Reading the notes from I Dell I found out that they do not have USB 3.1 cables ready yet. They will be available at a later time and can be easily replaced at the side of the dock. This has nothing to do with the physical form of the cable (USB type C), just with the protocol they use for communicating.
Status:
- Checking the new Thunderbolt dock with Xubuntu 15.10 did reveal that the two didn't like each other at all. (I don't particularly remember the kernel version I had installed). With Xubuntu 16.10 the dock is at least recognized when booting up (as previously outlined, it is best to have the dock plugged in before you boot up!)
- What works:
- Power supply
- Displays connectivity (partially, the EDID files seems get lost underway. I am currently running a 2560x1600 screen which is not even recognized to manage FullHD)
- Power button
- What does not work:
- USB (front and back)
- Audio jack
- Ethernet
- Additional thunderbolt plug
Tweaks:
- As I used this screen earlier with HDMI already, I had to manually add the corresponding xrandr modes. So I knew there is an easy workaround for the missing / scrambled EDID files. Currently I have the screen attached to the thunderbolt dock and using the following few lines to make it show the supposed resolution:
Code:
xrandr --newmode "2560x1600_30.00" 164.25 2560 2696 2960 3360 1600 1603 1609 1630 -hsync +vsync
xrandr --addmode DP-1-2 "2560x1600_30.00"
xrandr --output DP-1-2 --mode "2560x1600_30.00"
xrandr --output eDP-1 --off
- I did not manage to make the screen show 60 Hertz, even though its attached via display port. For now I stick to 30 Hertz
- In order to find the mode you require use:
Code:
cvt [Resolution X axis] [Resolution Y axis] [refresh]
- e.g.,
Summary:
The TB15 saved me 2 plugs (power + hdmi). However, now I can't use my USB 3.1 ethernet adapter anymore. I need to stick to Wifi for the time being (which is considerably slower in my office environment
). I am really looking forward for better Kernel support of Thunderbolt 3 protocol in order to use all the advantages of the new TB dock.
