I have the WD19 and I have to say despite it's being a fucking computer on its own it works astonishingly well under Linux, especially compared to the docking stations I had before. Feels like they really cared about their Linux support. Tested with both my XPS 9310 and my Precision 7530.
If you want to answer they have to because they sell Linux preinstalled: Their Ubuntu is garbage. If you setup Archlinux on your own, some features which haven't worked before will work, for example backlight oder hw acceleration.
Still better than Lenovo telling it's a feature to not setup proprietairy Linux drivers on devices who need them.
I have a 9310, and the stock Ubuntu was OK. The biggest issue is thermald was older and limited the frequency boosting (so lower perf).
I run 20.10 now with thermald master and kernel 5.10.1 (includes patches which enable pc10 sleep states and 400mhz cpu idle speed). Now it boosts and idles appropriately.
What’s “backlight oder hw acceleration” are you referring to refresh rate or something like PSR? I want to know if it’s something I need to check on my 9310...
"oder" is "or" in German, so I think they meant "backlight or hw acceleration".
I own a more recent Dell XPS 13, and the keyboard backlight support is indeed buggy - it needs a configuration patch to prevent it from turning on on logon.
Not sure what's exactly the hw acceleration. If they refer to the Intel integrated GPUs, the configuration is pretty much standard; up to 18.04 the only thing I needed to configure was the VSync (this was the same also for other laptops), but with 20.04, I didn't need anymore.
