TB15 Dock Linux Support

My setup: A Dell XPS 13 9350 and a TB15

I will test during the weekend. I installed a new bios, a new thunderbolt firmware, a new firmware on the TB15 and it looks as if I also had to update to the current vanilla kernel 4.8.12 to get "everything" working again.

First benefit: My Logitech 1000Hz USB receiver seems to work now with the dock.

The problem with sshfs still persists: Doing a "ls -R" cuts off the mountpoint (it get's empty like it was never mounted) after a view lines of output. The ethernet connection stays up and persists working.

I would be grateful if someone could post a step-by-step recipe to get my XPS13 9350 to work with my TB15 dock please. I have been trying to follow this forum but I get confused with the number of tweaks that seem to be needed. Experience so far: can run screen (HDMI); no network; no USB.

I am currently running ubuntu 16.04LTS with a 4.8.6 kernel. I have also upgraded BIOS to latest version 1.4.10.

Thanks

I know this is no help, but for me it was plug n play. I received both in September, so it probably already had the right firmware.

I use it with one external FullHD monitor over HDMI.

Network and the USB ports everything works nicely.

I just have to start my laptop without the dock plugged in then plug the dock in after I log into my session, otherwise the dock is not noticed by the 9350. The output sound line in the back is recognized but not configured correctly in pulseaudio for me so only some alsa-oriented sound programs know how to access it. Fortunately, the front sound out works fine out of the box. I switched to the Intel wireless card.

Everything else seems to work. Repeated docking/undocking though does seem to confuse the drivers after awhile but I've not discovered the pattern behind it. I also found it best to sleep via the power button the dock versus the laptop and I unload the wireless drivers before sleeping regardless of whether I am using the dock or not.

Everything else seems to work fine for me, network, USB and outputs for my displays (HDMI and mDP).

The one cable for everything seems to work good enough to get work done.

We do need, however, better user-configurable, high dpi support per monitor in the sessions, but it'll get there.

I still need to see if HDMI on the DA200 adapter ever started working, that's a sore spot.

BTW, if anyone knows how to create the right pulseaudio config so that the USB output sound line in the back of the dock works, I'm all ears. I've tried doing the udev/pulseaudio-also config thing but I'm out of my depth on trying to link the different parts together so that the rear sound output is used unless something is plugged into the front or the the laptop. I opened up a ticket over on freedesktop but I think we are on our own to make this work for the TB15.

Latest BIOS update 1.2.18 specifically claims:

5.Improved the DELL ThunderBolt Dock Stability

Does anybody see any improvement?

Hi,

the main issues currently bothering me are not yet resolved.

1) The TB15 still only works after hotplugging, but does not work when plugged in before powering on the computer

2) sshfs still is not working using the TB15 ethernet interface

My System:

A Dell XPS 13 9350, Debian Linux with a Vanilla kernel 4.9.0, latest TB15 firmware and latest Bios version.

Latest XPS 13 9360 1.2.3 BIOS  <ADMIN NOTE: Broken link has been removed from this post by Dell> specifically claims:

2. Fixed Dell Thunderbolt Dock may lost during Cold Boot \ Cold Boot

Does anybody see any improvement?

We (xps 15 9550 owners) just got a new bios version too (1.2.18 A16). Here are the changes listed:

1.Fixed system may drop battery un-expected
2.Improve PCIE NVMe Stability
3.Fixed Panel flick issue
4.Fixed Microsoft Bitlocker issue
5.Improved the DELL ThunderBolt Dock Stability
6.Fixed ST Microelectronics Motion Sensor Driver shows disabled while spindle HDD +mSATA installed

With the update I've noticed that the display backlight flickering issue is now gone (!), but I see no improvement in the dock's operation.

- My dock's USB subsystem is still broken on cold boot into Linux

- High speed Gigabit ethernet transfers through the dock are still broken, giving kernel error messages: xhci_hcd 0000:0e:00.0: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 2 comp_code 13

xhci_hcd 0000:0e:00.0: Looking for event-dma 0000000475ba5010 trb-start 0000000475b87fe0 trb-end 0000000475b87fe0 seg-start 0000000475b87000 seg-end 0000000475b87ff0

- A HDMI display connected to the dock is still "randomly" disconnected (my best guess here is that this is caused by some poor internal dock thermal design)

No improvements with the new vanilla kernel 4.9.1 of today on my (waste-of-time-and-money)-setup Dell XPS 13 9350 with latest Bios 1.4.12 and latest firmware on the TB 15 dock.

No sshfs via ethernet card, no coldboot.

After writing quite a few posts, and after creating an account and after logging in, THE I AM NOT A ROBOT THINGY IS JUST SUPER ANNOYING.

This forum is probably setup by the same guys who worked on the TB15.

Any one make TB15 usb ports works with a Presicion M5510?

A former colleague said he got it working under the 4.9 kernel.

Is there any dock available that would allow me to connect XPS 9360 Ubuntu 16.04, to external monitor, ethernet port and bluetooth mouse/keyboard and speakers?
