I have a Dell Precision 3530 and a Dell TB16 docking station. Like many others, I'm having trouble using this dock, especially on Linux, but to some extent also on Windows. I'm running Kubuntu 16.04. I am currently running kernel 4.15.0-47, and the intel graphics drivers. (I don't have nvidia drivers installed currently.)



What works (at a clean boot):



  • Charging

  • Ethernet

  • HDMI and DP external displays

  • USB (external keyboard and mouse)

What doesn't work (at a clean boot):



  • Sound (the taskbar volume icon lists a "USB audio headphone" when the dock is connected, but I get no sound output -- only through the internal speakers)

So far it's alright and usable. However, after I suspend and resume, I also lose the external monitor support, which is a bigger issue than not having external sound. I can see the external monitor, dimmed, in the display configuration dialog, but it is disabled, and even if I click to enable it and apply, it just goes back to being disabled.



I also sometimes (but not always) loose Ethernet connection after suspend and resume.



Looking at the output of sudo journalctl, the most relevant information about the network connection that I can see is

As for the monitor information, if I unplug the HDMI cable and replug it in, I don't get an image on the external monitor and journalctl tells me the following:

On the other hand, if I plug the HDMI cable directly into the laptop instead of the TB16 dock, I do get an image on the external monitor and journalctl says:

So the most apparent thing is that the nouveau driver spits out a lot of timeout warnings when the HDMI is connected to the dock. Perhaps installing the nvidia driver instead might help. I will try that next.



Based on info from another thread, I also tried kernels 4.15.0-43 and 4.15.0-45, but they work even less for me. Then I have no Ethernet connection through the dock, only via the laptop connector, and no wifi.



I have upgraded the firmware of the dock to the latest version.



Does anyone know of a configuration that works with 16.04 and Dell thunderbolt docks?



Under Windows 10, the dock works but the external monitor flickers off and on every now and then.

I have a Dell Precision 3530 and a Dell TB16 docking station. Like many others, I'm having trouble using this dock, especially on Linux, but to some extent also on Windows. I'm running Kubuntu 16.04. I am currently running kernel 4.15.0-47, and the intel graphics drivers. (I don't have nvidia drivers installed currently.)



What works (at a clean boot):



  • Charging

  • Ethernet

  • HDMI and DP external displays

  • USB (external keyboard and mouse)

What doesn't work (at a clean boot):



  • Sound (the taskbar volume icon lists a "USB audio headphone" when the dock is connected, but I get no sound output -- only through the internal speakers)

So far it's alright and usable. However, after I suspend and resume, I also lose the external monitor support, which is a bigger issue than not having external sound. I can see the external monitor, dimmed, in the display configuration dialog, but it is disabled, and even if I click to enable it and apply, it just goes back to being disabled.



I also sometimes (but not always) loose Ethernet connection after suspend and resume.



Looking at the output of sudo journalctl, the most relevant information about the network connection that I can see is

So the most apparent thing is that the nouveau driver spits out a lot of timeout warnings when the HDMI is connected to the dock. Perhaps installing the nvidia driver instead might help. I will try that next.



Based on info from another thread, I also tried kernels 4.15.0-43 and 4.15.0-45, but they work even less for me. Then I have no Ethernet connection through the dock, only via the laptop connector, and no wifi.



I have upgraded the firmware of the dock to the latest version.



Does anyone know of a configuration that works with 16.04 and Dell thunderbolt docks?



Under Windows 10, the dock works but the external monitor flickers off and on every now and then.

    After resuming type journalctl and look for error messages.

I have a Dell Precision 3530 and a Dell TB16 docking station. Like many others, I'm having trouble using this dock, especially on Linux, but to some extent also on Windows. I'm running Kubuntu 16.04. I am currently running kernel 4.15.0-47, and the intel graphics drivers. (I don't have nvidia drivers installed currently.)



What works (at a clean boot):



  • Charging

  • Ethernet

  • HDMI and DP external displays

  • USB (external keyboard and mouse)

What doesn't work (at a clean boot):



  • Sound (the taskbar volume icon lists a "USB audio headphone" when the dock is connected, but I get no sound output -- only through the internal speakers)

So far it's alright and usable. However, after I suspend and resume, I also lose the external monitor support, which is a bigger issue than not having external sound. I can see the external monitor, dimmed, in the display configuration dialog, but it is disabled, and even if I click to enable it and apply, it just goes back to being disabled.



I also sometimes (but not always) loose Ethernet connection after suspend and resume.



Looking at the output of sudo journalctl, the most relevant information about the network connection that I can see is

So the most apparent thing is that the nouveau driver spits out a lot of timeout warnings when the HDMI is connected to the dock. Perhaps installing the nvidia driver instead might help. I will try that next.



Based on info from another thread, I also tried kernels 4.15.0-43 and 4.15.0-45, but they work even less for me. Then I have no Ethernet connection through the dock, only via the laptop connector, and no wifi.



I have upgraded the firmware of the dock to the latest version.



Does anyone know of a configuration that works with 16.04 and Dell thunderbolt docks?



Under Windows 10, the dock works but the external monitor flickers off and on every now and then.






16.04 dell







share|improve this question
















I have a Dell Precision 3530 and a Dell TB16 docking station. Like many others, I'm having trouble using this dock, especially on Linux, but to some extent also on Windows. I'm running Kubuntu 16.04. I am currently running kernel 4.15.0-47, and the intel graphics drivers. (I don't have nvidia drivers installed currently.)



What works (at a clean boot):



  • Charging

  • Ethernet

  • HDMI and DP external displays

  • USB (external keyboard and mouse)

What doesn't work (at a clean boot):



  • Sound (the taskbar volume icon lists a "USB audio headphone" when the dock is connected, but I get no sound output -- only through the internal speakers)

So far it's alright and usable. However, after I suspend and resume, I also lose the external monitor support, which is a bigger issue than not having external sound. I can see the external monitor, dimmed, in the display configuration dialog, but it is disabled, and even if I click to enable it and apply, it just goes back to being disabled.



I also sometimes (but not always) loose Ethernet connection after suspend and resume.



Looking at the output of sudo journalctl, the most relevant information about the network connection that I can see is

On the other hand, if I plug the HDMI cable directly into the laptop instead of the TB16 dock, I do get an image on the external monitor and journalctl says:

So the most apparent thing is that the nouveau driver spits out a lot of timeout warnings when the HDMI is connected to the dock. Perhaps installing the nvidia driver instead might help. I will try that next.



Based on info from another thread, I also tried kernels 4.15.0-43 and 4.15.0-45, but they work even less for me. Then I have no Ethernet connection through the dock, only via the laptop connector, and no wifi.



I have upgraded the firmware of the dock to the latest version.



Does anyone know of a configuration that works with 16.04 and Dell thunderbolt docks?



Under Windows 10, the dock works but the external monitor flickers off and on every now and then.






16.04 dell




16.04 dell

I've had the same issue with my TB16 and XPS13, but on Ubuntu 18.10. To have all my devices which work, I had to update the TB16 Firmware from windows 10 (Dell driver app), and remove security of thunderbolt connection inside the bios.



After that, the resuming work fine and all devices (audio, ethernet, keyboard,...) too.
