So, there is one problem I cannot seem to get fixed with almost any Linux distro. Auto-display detection.
Using a Lenovo E490 laptop with USBC gen 3 dock DisplayPort to external display. The problem arises when I am not docked. If I boot the laptop off dock, I get the XFCE login screen but it goes black after login. This is because I have the laptop display disabled when docked - otherwise, the external display does not display properly. But how can I have the connected resources automatically detected and the appropriate settings applied? Without an external display, my laptop is screen less.
LOL it has gotten so bad, I am on my Windows laptop today… oh god…
Have you tried other DE? Somehow I got on the gnome wagon for the past two weeks.
It is the first time for a year that my laptop and external screens just work as they are supposed to. I am quite amazed. I plug in my laptop to my usb 3 Docking and it recognize lapi and 4k screen. I close the laptop, the external screen flips to being main desktop. I plug in additional hdmi into closed laptop and secondary screen is recognized no problem!

If it truly comes down to that, I guess I might have to go that route. I just really like the combo of having i3 and the GUI stuff from XFCE (not partial to XFCE at all, just wanted GUI for settings apps and such).
If that your “only” requirement gnome+pop_shell does the same thing. You will have the DE goodies and tiling using pop_shell.
I’m very biased because I love gnome but that being said you should really try it and see if you like it.

So it works fine as a laptop. . . And then when you plug it into the dock, you need to manually change the display settings each time?
I’ll try and look into it today. But that may be a limitation of XFCE. It’s not known for being quite as posh as some of the other DEs.
FWIW, i also have a t480s with USB C dock and i have the EXACT same problem with both Windows and KDE on initial startup. It works ok after I’m booted in. But from a cold start i get flickering (Windows especially) and a black screen on KDE.
It may just be a limitation of the Thinkpad dock firmware.
