Nothing particularly interesting in the log. There is a normal looking
disable->do nothing for ~26 minutes->re-enable modeset sequence (presuambly the
display was just blanked for that period of time?). Also a ton of some ASLE
junk but presumably that should be harmless.

Given the evidence we have I'd lean towards the DP++ dongle simply being
garbage.
