--- Comment #10 from Harry Wentland <harry.wentland at amd.com> ---
Alex is correct about the intention of this change. I've never played around
with the modeline before so don't fully understand the impact of having that in
the xorg.conf. It sounds like that's forcing certain modes which we then can't
support due to the commit you mention.

We have an open issue where we don't correctly filter out modes if we can't
support them for whatever reason. Fixing that might help you but we don't have
anyone looking at it yet.

As for the behavior you're seeing with the modelines removed, I don't fully
understand what you're seeing. Mind posting a picture? It sounds like we should
be driving the monitor in 4k30 at that point but seems like something goes
wrong there, from your description.
