Comment 22 for bug 1773581

Sorry for the delay. I just manged to test the patched kernel:

> uname -a
Linux winki 4.13.0-43-generic #48 SMP Tue May 29 03:12:08 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

but unfortunately that didn't solve the issue (see attached photo). I wonder if some of the other three commits are responsible:

> git log --oneline Ubuntu-hwe-4.13.0-41.46_16.04.1..Ubuntu-hwe-4.13.0-43.48_16.04.1 -- drivers/gpu/drm/i915

116b5d5 drm/i915/edp: Do not do link training fallback or prune modes on EDP
01a7507 drm/i915/dp: make is_edp non-static and rename to intel_dp_is_edp
