--- Comment #15 from n0000b n0000b.n000b@gmail.com --- Hi! i've been experiencing some similar issue. (i posted in bug https://bugs.freedesktop.org/show_bug.cgi?id=43829.)
Have you tried with sudo pm-suspend --quirk-test --quirk-s3-bios
because if i run this my screen is able to turn on after the resume. Can you try it?
