            Bug ID: 106192
           Summary: 4.16.2+ lightdm logon screen will not unblank after
                    monitors fall asleep
           Product: DRI
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org

Initial boot - everything was fine.

If I leave my computer at the logon screen and the monitors fall asleep, I
cannot wake them. Requires a reboot.

Looks like there was a dmesg error, and Xorg.0.log reflects a failure when
attempting to use screen 0.

I'll include the xorg.conf because that may have had something to do with it
according to the Xorg.0.log.

Dmesg shows kernel error after freezing. Had to acquire with ssh.

Looks like a kernel bug issue. This
