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!
~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.
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
This depends more on your individual hardware; if your device has thunderbolt 3 or 4, you should go with a thunderbolt dock. I'm using one from HP, probably the predecessor of this one (because mine is flatter): https://www.hp.com/us-en/shop/pdp/hp-thunderbolt-dock-120w-g2
Works pretty much without any extra drivers while the maintenance of my gf's displaylink-based dock is a pain... Displaylink only distributes packages for the Ubuntu LTS versions, so if you are on sth with newer kernels (e.g. PopOS) you have to hold the kernel packages etc. Not fun. Will move her to arch soon.
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'd recommend the CalDigit dock though as the Kensington one has developer coil whine so if I'm not using the linux laptop I power it down and unplug the laptop to stop the annoying sound. The TS4 has no such issues.
