Sometimes when I poweroff the screen, then after some time I turn on it aga=
in,
the system cannot recognize native screen resolution, and sets it to a weird
one. In Plasma system settings, the monitor name is unknown and the native
resolution is missing (1600x1050), other resolutions are available instead..
After playing with some resolutions, suddendly the screen name (ViewSonic e=
tc.)
returns back.

MrCooper user in #radeon Freenode chat, suggested me to start the system wi=
th
amdgpu.dc=3D0 flag. 24 hours of testing seems to confirm that such flag fix=
es the
problem.

I attach dmesg and xorg.0.log of system experiencing the problem
