My experience is on a dell precision which is pretty much the same as the XPS

It seems this is the same bug for Dell XPS 15 as well. Not always, but
sometimes this happens either using the DA200 adapter (Type-C usb) or
direct HDMI. However, a related bug has been fixed (black screen)* so I
will report back if this still happens on the Dell XPS 15.

Thanks for the helpful link. I tested the kernel v4.11 and this fixes the
issue. Now, the Display is also running at 60 Hz (not 30 as it was before).
There are still some minor errors in kernel.log when plugging In/Out but
everything seems to work.
** Attachment added: "Kernel Logs - fixed"
Did this issue start happening after an update/upgrade? Was there a
prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.11
