--- Comment #38 from Chí-Thanh Christopher Nguyễn chithanh@gentoo.org --- Created attachment 141163 --> https://bugs.freedesktop.org/attachment.cgi?id=141163&action=edit patch against 4.18.1
I tried the latest patch too, and LVDS is now working (as expected, VGA does not work).
I slightly adapted the patch so that it applies against linux 4.18.1, in case anyone is interested.
