RE: TB16 Dock Linux Support

I'd love to update the firmware. I don't have any Windows computer, nor any Windows licenses, however. Presumably to use that ISO I would need at least the latter?

You can use same ISO to install Windows on a virtual machine on top of linux. I think VirtualBox should support the USB harddrive, so you can run the software and create the live-Windows drive there. Haven't tried this approach though.

RE: TB16 Dock Linux Support

Running opensuse tumbleweed.

I use the TB16 with the XPS9360 on 1 external 4K display, works fine most of the time.

Ethernet works a few minutes, then loses it completely. I've given up making it work.

USB sometimes work, sometimes not.

I don't understand why the TB16 runs the fan so often (and so loud) though, there seems to be absolutely no reason for it.

Kernel 4.11 is normally bringing some usb-c and thunderbolt improvement.

RE: TB16 Dock Linux Support

@madchap: Are you maybe suffering from the known gigabit ethernet connection problem?

Regarding fan noise, it is the same problem when running Windows, so this is not because of the OS or the kernel. Either my/our TB16 has some fault, or it is the combination of XPS 9360 and TB16. I have other colleagues with different Dell models, and they report their new TB16 being quiet as grave.

RE: TB16 Dock Linux Support

The noise from it is fairly quiet. I have to listen carefully to hear it. I was just very surprised because I didn't expect it to make any noise at all or have any fans. It's not a huge problem, just odd I suppose.

By the way regarding the USB flakiness issue, I've been using my USB mouse in one of the back ports without issue for the past couple days.

"Enter TB16: All problems gone."

I have a Dell Precision 5520 running stock Ubuntu 16.04 with TB16 and two 2560x1600 Dell U3011 external monitors, each hooked up via DisplayPort and mini DisplayPort to dual link DVI adapter. Laptop BIOS is latest and Thunderbolt firmware is the latest.

Here's the problem: After undocking and then suspending the laptop will never resume properly; the keyboard and power button start to glow after resume but the screen always stays black. At this point my only option is a hard reboot. Docking at this point also doesn't help :-(

@tfnico have you tried suspend / resume after undocking? Does it work for you?

RE: TB16 Dock Linux Support

Network hasn't worked for me in quite a while with the TB16.  It was working wonderfully when I first had it delivered but at some point it simply stopped.  Video still works.  USB doesn't.

I have reinstalled the original recovery image and updated with no luck.  I have installed regular Ubuntu 16.10 and 17.04 seperatly but with no joy and now using Ubuntu Gnome 17.04 with no sucesss either.

Unsure what has caused it to stop.  The network lights are on but no one home.

The computer does not recognise there is any NIC available.

Perhaps there is a set of drivers that haven't made their way upstream and need to be manually installed?

RE: TB16 Dock Linux Support

@Simon Hardy-Francis: I dock and undock with suspend all the time. It works fine. What kernel are you on? I only have one external monitor, you could see if that makes a difference.

I did have your exact black screen problem when I was still using the WD15. It was killing me, had to hard reboot every day. I switched to the TB16 when I upgraded all the firmware/chipsets via Windows, but some quick tests with the WD15 showed that the problems were still present. Not with the TB16 however. I should re-test though, and double-check whether the upgrades may have fixed my issues with the WD15 as well.

For reference, I've got XPS 13 9360 DE with UHD. Stock Ubuntu 16.04 with kernel 4.9.22. External display is Dell P2715Q connected via mini-DisplayPort in the TB16 at 4k (3840x2160).

RE: TB16 Dock Linux Support

After a few weeks with the TB16, I have a more sober impression and have discovered a few nits.

Here's the setup:

  • Laptop: XPS 13 9360 DE with UHD
  • OS: Stock Ubuntu 16.04 with kernel 4.9.22.
  • Peripherals: External display is Dell P2715Q connected via mini-DisplayPort in the TB16 at 4k (3840x2160). Some Logitech USB webcam and a USB headset. Bluetooth mouse & keyboard.

Check-list for the TB16:

  • Charging: Works. No issues.
  • External display: Works with full 4k. No issues. Hot plugging shows a messed up layout for a second before it corrects itself. No resuming from suspend crashes or login freezes (like I experienced with the WD15).
  • USB: They work but sometimes they will crash, or hang, and I have to retreat to the ports on the laptop. Rebooting laptop seems to be the only fix for this.
  • Ethernet: Works, BUT only with 100 mbps connection (gigabit connection corrupts plenty of data), and I have noticed that using the ethernet port is what triggers the crazy fan activity! Super weird. 
  • Headset jack (front): "USB Audio Analog Stereo" is recognized as an input device, but not as an output device. Weird.
  • Audio line out (back): Does not work at all.

For reference, on the WD15, the headset jack in the front, ethernet and USB ports worked fine. Audio line out in the back didn't work there either.

RE: TB16 Dock Linux Support

@carriagereturn: When I shut the laptop when connected to the external display (see my setup in previous post), the system and the external display remains on. Only the internal display is disabled. Opening the laptop re-activates the internal display again. So that works quite smooth at least.

RE: TB16 Dock Linux Support

@tfnico thanks for the suggestions.

I have the stock Ubuntu kernel supplied by Dell for the Precision 5520 which I suspect is not the 4.9 version but I'll check later when I have access to the laptop. Did you upgrade the kernel yourself and if so, how easy is it to do / do you have the instructions?

Regarding the internal display then I went for the FHD display in order to maximize battery life.

Regarding one or two monitors: I tried all combinations of no external monitors, 1 DisplayPort external monitor, 1 mini DisplayPort external monitor, and both external monitors. But whenever there's an external monitor connected and I undock and suspend, then the subsequent resume results in the black screen issue. Undocking, suspending and resume works fine if no external monitors are connected to the dock.

Regarding upgrading via Windows: I created a Windows to go USB drive to update via Windows and updated the on laptop Thunderbolt firmware. I assumed that the chipset updates were all Windows specific. Or do you think they have some sort of effect on Ubuntu?
