Flickering single display in multi-head XRandR setup

[martin f krafft]

Hi Andreas,

Thank you for taking your time to reply. I've since followed up
having found the problem, and I think it must be one of the DP ports
on the graphics card.

Now, you write:

This leads me to believe that the connector hardware itself could be
at fault. Seriously, is DP *that* finicky and subject to connection
failures? I'd have thought that it being 2016, the industry would
have finally gotten the hang of it, especially after screwing up
HDMI so badly.

Thanks,
