Thanks Marc!

Is great to have some feedback now.

After looking again into the files of the card0, I have noticed that dpm is
enabled by default! (I have been confused because the file changed its plac=
e).


Now it is here:

cat /sys/class/drm/card0/power/control=20
auto

uname -a
Linux powers11 4.16.1-300.fc28.x86_64 #1 SMP Mon Apr 9 15:29:05 UTC 2018 x8=
6_64
x86_64 x86_64 GNU/Linux

Also their outpus have same files:

/sys/class/drm/card0/
card0-DP-1/     card0-HDMI-A-1/ device/         subsystem/
card0-DVI-D-1/  dev             power/          uevent

So it is really fixed for fedora 28!! (kernel 4.16.x)

I have been using this for weeks and not noticed this bug!

Also tested glmark2 and some game just to see if something crashes.
