--- Comment #17 from Chí-Thanh Christopher Nguyễn chithanh@gentoo.org --- Created attachment 138863 --> https://bugs.freedesktop.org/attachment.cgi?id=138863&action=edit dmesg from kernel 4.15 with attachment 138831 applied
So I applied this patch from bug 105596
The "Unsupported Connector type:14" message is gone, the "Unsupported Connector type:5" is still there (as expected).
However the screen stays blank and the "[drm] Cannot find any crtc or sizes" message sill comes.
