after using a lenovo usb c dock and having a lot of display problems. its a displaylink chip. and random disconnects (doesn’t happen on my windows work laptop). i was wondering what are the best supported docks for linux?
in my current situation the dock has the displays, ethernet, keyboard/mouse and audio connected to it so i can easily switch between my work laptop and my desktop pc.
Not a direct answer to your question, but I have a Dell TB16 dock. It does not work well - it sporadically fails to output display to my monitors and it does not charge my non-dell personal laptop (a Lenovo Yoga 730). However, it works great for my Dell work laptop running windows…
Just adding this Incase you see it on sale or something - take it for what it’s worth!
The Dell dock works great with my framework after I installed their display link drivers (proprietary blob unfortunately).
The display link drivers are the problem for me. Makes everything so unstable.
Its the worst for Linux, but works great if you need video out on an android device without video output.
~I use mine on an XPS, but I have no issues with it driving two displays in either Ubuntu nor Debian. Works fine!~ scratch that I use a WD19-TB, not the same thing.
Probably Thunderbolt docks are better. Should also provide better performance as Display Link compresses the video stream on your CPU before sending over USB.
Which lenovo dock were you using? I was recently looking at getting the lenovo USBC gen2 (40AS) dock which I am pretty sure uses displayport alt mode and not displaylink.
I used to use a Dell WD19TB (that’s the thunderbolt version) and I remembered a period of time where it worked better running on PopOS than it did on Windows 10
Just ordered a i-tec USB-C Dockingstation 3x4K with alt mode. Tomorrow I hopefully can say it is working
I have a Kensington SD5700T and a CalDigit TS4. Both of those are USB 4/Thunderbolt 4 docs and they work fine under Fedora. They support 2 monitors out via USB C or a combination of USB C/HDMI.
I have to use Windows because of the docking station problems with Lenovo…
The only feasible workaround for me was to use the HDMI out for the display and the station for the rest but that defeats the purpose of said station.
I did get it somewhat working by switching to Ubuntu in combination with the Ubuntu display link driver. But it’s never stable
