Dear Maintainer,

When I plug a monitor into the laptop via VGA, all is well.   When I plug the
same monitor in via DisplayPort, I see a backtrace appear on console and the
monitor doesn't sync.   The problem is 100% reproducible, so I can send more
debug info if that's warranted.    (And I can install new kernel with more
debug options and reproduce, if you like).    I just upgraded kscreen to
kscreen:amd64 4:5.4.0-1 and had hoped that would help, but it made no
difference.

Here is the console message:
