Bug ID: 107465
Summary: Weird resolution
Product: DRI
Version: XOrg git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org
Reporter: germano.massullo@gmail.com
Videocard: RX480
OS: Fedora 28 KDE
Kernel 4.17.9-200.fc28.x86_64
Sometimes when I poweroff the screen, then after some time I turn on it again,
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 etc.)
returns back.
MrCooper user in #radeon Freenode chat, suggested me to start the system with
amdgpu.dc=0 flag. 24 hours of testing seems to confirm that such flag fixes the
problem.
I attach dmesg and xorg.0.log of system experiencing the problem

Just a clarification: title "amdgpu.dc=1" is not meant as having amdgpu.dc=1 as
setted boot parameter, the situation is:
no boot parameter = problem triggered
amdgpu.dc=0 = no problem
