            Bug ID: 108110
           Summary: hades canyon can not wake from dpms on mDP
           Product: DRI
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium

I am having an issue with intel NUC8i7HNK. I have three Dell U2415 monitors
connected to one mDP daisychained. When the monitors go to sleep (dpms) trying
to wake up the monitors after half hour or more fails, touching the keyboard
and mouse. Only way is a hard reboot. Same monitors connected to other systems
wake up fine. This system has AMD Vega M graphics but Intel graphics drive the
displays. Is this correct?

--Thanks
