Re: ThunderBolt 3 Dockingstation and Linux?

2018-05-11, 13:02 PM

I have the TB3 dock and am using it with Fedora 28 on a X1 Yoga 3.  USB, notebook charging over thunderbolt, 2 external displays plus the built in display work simultaneously (no flickering), network adaptor, audio jack.....it all works out of the box. Hotplugging and unplugging works fine too. 

 

If you use gnome, make sure to set thunderbolt security settings to User (in bios) and then goto the thunderbolt settings in gnome settings and authenticate.  Otherwse you may need to set security settings in bios to off (or install boltd and  authentica via cli).  Haven't tried 4k monitors.

Thx for your answer!

 

But 4k is a critical point cause you need much more bandwith for the high resolution

They are pricy.

But I now have 3 external monitors hooked up to one, plus ethernet and a wireless keyboard.

To get USB on the docking station to work in Linux I had to disable security for Thunderbolt connections in the BIOS.  I'm not sure what the security got me, so I'm ok with that.

Now, if only we could use the docking station for charging, I would be over the moon.


I'm looking at this dock for a Yoga 370 running Linux and I want to use 3 external 1920x1080 monitors. Can you confirm that you are using the ThinkPad Thunderbolt 3 Dock model 40ac and it connects 3 external monitors under Linux? (I'll blank the laptop screen when using 3 external monitors.)

 

I can do without docking station charging if I can get 3 monitor support.

Can anyone tell me if it's possible to connect two 4k Screens @60Hz?

See https://support.lenovo.com/us/en/solutions/pd029622#Thunderbolt

 

That matrix shows that you can connect two displays at 3840*2160@60Hz. (That resolution is typically considered 4K.)

If your laptop is dual boot, you can "accept" thunderbolt docking station in Windows. The signing happens at BIOS level and you do not have to disable "thunderbolt 3 security" to use docking station in Linux.

Actually you can do this also without Windows. There is a tool for managing these authentications called boltd. If your Linux distribution has boltd installed, it comes with a configuration utility called boltctl. Use boltctl list to list all plugged Thunderbolt devices and see their UUIDs, then use boltctl authorize (UUID) to authorize a specific device. You need superuser privileges for that.

Hi guys, for those who have multiple monitors, what is your dedicated GPU ?

 

Do you make use of the Nvidia proprietary driver on all your screens without any bad consequence ?

 

Does it work out of the box ?

 

By any chance, do some of you use CUDA ?

 

Regards

Thanks for the tip about BIOS/Thunderbolt setting.  After I did that, I can use the TB3 with my X1E.  Accessing USB disks works fine, and I connected a 4K monitor via HDMI to the dock.  What does not (yet?) work is sound output.  Does anybody else have problems with that?  Could it be that the system gets confused with sound output to the HDMI connection and not the 3.5mm output in the front?

 

BTW, I am using Debian Buster.

 

 

cheers,

Werner

Hi , the sound issue can be related to device profiles of your sound card (in my case Build-in Audio). Let me explain my situation, maybe yours is similar: In system audio settings (probably based on PulseAudio) I can either select profile Analog Stereo Output to use computer speakers or jack, or another HDMI profile to use sound over USB-C or HDMI. They cannot be used at once and the first one is selected by default. (On the other hand other devices I have – BT speakers, headphones... – can be used at once, because they have their own sound cards, so the profile selection for the build-in one does not affect them. My Lenovo USB-C Dock is IIRC having integrated sound card, I suppose ThunderBolt Dock will have it as well, so the issue will probably be somewhere else anyway.)
