XPS 13, WD19TB dock and Manjaro

Support
1

Kia Ora everyone,

I’m having a few issues with a Dell XPS 13 (9300) and a WD19TB thunderbolt dock displaying output to my monitors and I love to narrow down whether anything is wrong or if I am just expecting too much.

When at my desk I use my laptop with the lid shut and work on two external displays, an LG 34GK950F (3440x1440 @ 60hz via active USB-C DP to HDMI) and an AOC (1920x1080 @ 60hz via DP).

If I boot from cold sometimes the first thing I will see is the log in screen but most of the time I won’t get any display until I unplug the dock and plug it back into the laptop.
Often this doesn’t result in a display either and I’ll have to open the laptop, boot into the desktop, connect the dock and then close the lid - And even then my external displays don’t always come back, often enough to warrant me making this post.

I have checked the bios, all pre-boot related TB options are turned on and the signs of life options are turned off as per the wiki.
It seems that using the USB-C DP to HDMI is more reliable that just using HDMI.
I have tested with only the LG monitor and I have very much the same experience.

I’ve tried a number of different distros with similar results. Ubuntu does seem to be the best but only from a short amount of testing. Been using Manjaro for a couple of years now though so ideally would like try to fix on here before considering a move.

Appreciate any help you folks might have to make these problems go away.

Thanks

I have exactly the same hardware (xps9300+wd19tb), same problem and also tested other distros like ubuntu without any success.
