From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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 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

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.

Probably Thunderbolt docks are better. Should also provide better performance as Display Link compresses the video stream on your CPU before sending over USB.

This dock has worked well with my System 76 Lemur.

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

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.

For the displaylink, are you using the drivers provided by Synaptics? The driver itself is not opensource, so I doubt you can find it on your distro's oficial repos

There are drivers for this? I've had to switch away from Linux at work ever since 6.1 because of this
