Kernel is 4.18.8, 4.18.9(Arch), mainline(AUR), and drm/drm-intel(https://github.com/shunonymous/aur-linux-drm-intel-git).
My laptop displays nothing in builtin monitor when launching Wayland compositor.(weston, mutter)
It displays by connecting or disconnecting external monitor (by HDMI) (mutter. weston doesn't work).
startx works without any problem.

I tried to revert

on mainline, this symptom was disappeared.

Shun, Can you apply following path and test if the issue is still existing?
(https://bugs.freedesktop.org/attachment.cgi?id=141229).

If the issue persists, send dmesg from boot with kernel parameters
drm.debug=0x1e log_buf_len=4M. This way we know more information about
the bug.

Those commits need to be applied to 4.18 to fix this regression:

I think the same applies for the upcoming 4.19 as well.
