    I've build myself a new desktop earlier this year; with the AMD Ryzen™ 5 5600G and a NVMe SSD, ...
    The installation of openSUSE Tumbleweed worked without problems. The only thing that is not perfect is the AMDGPU driver.
    I experienced the same problems as described here:
    https://www.camillescott.org/2020/12/16/amdgpy-edid/

    And I'm working with Xorg only (KDE), because with Wayland the at every shutdown the system hangs.
    Even though I'm not sure, I would blame the AMDGPU driver for this too.

    With this knowledge, I would prefer an Intel CPU today.

    That link looks like a nightmare. Are there no bug report about this?

    AFAIK: no.
    I avoid the problem by using a displayport cable. That causes a few error messages in the boot process, but beside of three or four seconds more boot time everything works fine.
    If this problem occurs depends on the monitor. Mine tells the computer: "I can do RGB (computer mode) and YCbCr (TV mode)." In this case the AMDGPU driver uses - hard coded - TV mode.

    No idea what the monitor says.
