Looking for dual-monitor dock recommendation (display, USB)


I am running Qubes OS v4.1.0 on a Librem 14v1 laptop. I intend to typically use this at my desk with a dual-monitor, USB-A mouse, and USB-A keyboard setup. I would strongly prefer to use a dock so that I don’t need to constantly plug/unplug these 4 items into the laptop each time I want to work away from my desk, so I’m looking for a dock. For the display ports, I suppose HDMI or DisplayPort would do. I anticipate that such a port would connect to the laptop via USB-C, of which I have x2 (as well as x2 USB-A), but no Tunderbolt support.

This is not a request for just any dock that has these 4 ports, but I’m hoping someone can tell me of a dock they’ve used that works well with Qubes OS v4.1.0 (or at least v4.0) and meets these criteria. I would also strongly prefer to not have to install new drivers if possible (in that case, I may prefer to just not use a dock).

I’ve found a Cable Matters dock (https://www.amazon.com/Cable-Matters-Multiport-DisplayPort-Ethernet/dp/B0746NKVBN) that may work, but am not sure how well this plays with Qubes or if there is something better. I do acknowledge that this has Thunderbolt support, whereas my laptop does not, but it appears it may work over non-Thunderbolt USB-C unless I’m not understanding or reading this correctly.

For anyone interested, the dock I mentioned in the original post works pretty well with Qubes OS without needing to manually install drivers.

The only issue I’ve run into is the system usually crashes during boot-up with the dock plugged in. When this happens, it eventually takes me to a LUKS decryption screen which I’ve never seen before, but freezes here. If anyone has any idea what may cause this or how to fix it, please share.

I have the same problem with my cheapo dock ($60, some cheapo shit, thunderbold over USB-C tho, i don’t know. could investigate when requested).

Try to do the following:
++ctrl+alt+f1++, upon the luks prompt. Maybe without the alt, i am not sure.

This way you get into the chad tty and can enter your password.

What i observed on my system:

  1. In the grub menu my keyboard (connected to the dock) presses “E” kinda all the time. have to disconnect to processed
  2. Input into the luks prompt wont work
  3. When switching to TTY there are 4ish characters entered that i have to remove to enter my password

This is how i do it, and it works fine (enough), maybe this works for you too.
