dmesg
I'm using Gentoo kernel 4.5, after resume from hibernation I have black screen.
I tried two kernel versions 4.5.0-r1 and 4.5.3. In the end of dmesg after every
resume I see:
[drm:radeon_dp_link_train] *ERROR* displayport link status failed
[drm:radeon_dp_link_train] *ERROR* clock recovery failed
Does displayport means DisplayPort(<a href="https://en.wikipedia.org/wiki/DisplayPort">https://en.wikipedia.org/wiki/DisplayPort</a>)?
Because I don't have this in my laptop.
