--- Comment #3 from Phil Turmel <philip at turmel.org> ---
I have what is likely a related problem -- any change to resolution or
re-enabling an output on my system, via xrandr or the equivalent KDE dialog,
yields a black screen and/or artifacts from the framebuffer console.  When
multiple monitors are enabled, the affected outputs are black until the mouse
pointer moves in their region, yielding artifacts plus *correct* mouse pointer.

Until recently, operation was restored solely by restarting X.  With kernel
4.19.3, operation can be restored by switching to a text console (all connected
outputs turn on) and switching back to X.  The phenomenon occurs on all monitor
ports, on the dock or not, whether docked or not, and both before and after
suspend/resume.

Laptop is an HP ZBook 17 with GK107GLM (K1100M) with gentoo unstable:
