    Fedora 28 - Random Screen Flicker

    Hello,

    I am experiencing a random screen flicker in that it can occur no matter what I am doing. Also the issue is not present under Windows or Debian. Having recently switched from Windows I could do with pointing in the right direction as to diagnosing the issue i.e what log files would be useful in this situation?

    Code:
    Linux 4.16.13-300.fc28.x86_64 #1 SMP Wed May 30 14:31:00 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
    
    VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Curacao XT / Trinidad XT [Radeon R7 370 / R9 270X/370X] [1002:6810]
    	Subsystem: Micro-Star International Co., Ltd. [MSI] Device [1462:3030]
    	Kernel driver in use: radeon
    	Kernel modules: radeon, amdgpu


    Hopefully I have provided enough info

    Thanks
    Nick

    Solution was saving high or low in /sys/class/drm/card0/device/power_dpm_force_performance_level.
