Bug ID: 105465
Summary: Computer boots into black screen when MST is enabled
Product: DRI
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: DRM/Intel
Assignee: intel-gfx-bugs at lists.freedesktop.org
Reporter: johan.bjornehall at gmail.com

On kernel 4.15.8 (and a way back), computer boots into black screen every time
with multiple monitors connected with a single DisplayPort cable. Intel i3-6100
(Skylake) with Intel HD Graphics 530.
If MST is disabled in GRUB with i915.enable_dp_mst=0, the issue goes away but
leaves me with mirrored screens.
This issue occurred somewhere in november 2017, but I didn't file a bug report
because of the belief of misconfiguration.
More information about the symptom for the issue, can be obtained here.
