Thanks for pointing that out. I was wondering why so many
adapters/cables for sale only mention "USB" while also claiming to do
4K60Hz...

So Thunderbolt isn't required, only USB 3.1 Alternate Mode and a
powerful (probably only *integrated*)

Thank you for the response. I think these might fall into the third
category of 'VESA is its own special story' ?
I bought both the adapters from the dell configurator at the time I
bought the machine.
This is the part that flakes:

Hmm, it seems Thunderbolt-DisplayPort cables are pretty rare. Instead of
searching for those I suggest looking for adapters that are explicitly
for "Thunderbolt" and not "USB".
USB 3.0 has a bandwidth of 5 Gbps
USB 3.1 has a bandwidth of 10 Gbps
4K at 60Hz however requires 3840x2160x4 (33177600)
IIRC, upstream GNOME/mutter has done some fixes for dual-link displays

You certainly seem to have the latest and greatest Intel GPU which
should support 4K up to 120Hz:

Public bug reported:
I have some early dell 4k 60hz screens - the ones which report 2 panels
internally for DP 60Hz - horrid hack I know; I recently got a new XPS
laptop and put Ubuntu on it.
That XPS laptop has two USB-C/thunderbolt ports, so to drive the screens
I bought two slightly different
Just wanted to add that after someone suggested the problem might be in
GNOME, I've made a fresh installation of Kubuntu 20.04 and haven't had
any problem for 2 days.

Reproducible on my system. Whenever my computer "sleeps" while running a
specific program (Phenix), when I return to check on the job, the
Desktop screen does not load. Alt-F2 and other routes have not been

New bug for me. Issue was fine till last week. I think this may be
related to the following as it started happening shortly thereafter.
I have XPS13 with second monitor, all working fine till I lock screen or
suspend. Then my second monitor will not 'resume'. I.e. stays off.
