--- Comment #3 from AceLan Kao <acelan at gmail.com> ---
I didn't change anything, just install the mainline kernel, and toggling the
display.
Without drm.debug=0xe, the external monitor always shows blank while in mirror
mode.
Is there anything I could try to gather more useful logs? Or any debug patch I
can apply to collect meaningful log for you?
