Thread: Blank white screen after updating to openSUSE-release 20180209-1.2

    Default Blank white screen after updating to openSUSE-release 20180209-1.2

    After updating to openSUSE-release 20180209-1.2 (also via zypper dup), X does not start up anymore; I get a mouse cursor in front of an empty white screen. I have to roll back to get a graphic screen again.

    Driver: amdgpu (both dc=0 and dc=1).

    Graphics card: AMD Radeon RX480, HDMI to monitor.

    The reason is explained here: https://lists.opensuse.org/opensuse-.../msg00426.html

    You need to delete:

    ~/.cache/qtshadercache
    ~/.cache/mesa_shader_cache
    and
    /var/lib/sddm/.cache

    Someone else here also using amdgpu Fdriver had a similar problem a few days ago. There was an error message that referred to KFD. I am sorry but I cannot remember any more detail, you should be able to find it if you search the threads.

    There has also been a recent mention on the Phoronix forum. I think that it mentioned aa AMDKFD module that would not make it into the kernel until 4.16.

    I COULD ALSO BE TOTALLY WRONG. [edit] -- and it seems that I am!
    ~Thank you for sharing an interesting problem.

    OK, going to try with cleaning /var/lib/sddm/.cache.

    I had that issue some days ago, but there is sufficed to clean ~/.cache. In this case - the reason for my posting - it happened before the login screen was shown, so an involvement of a directory in the user tree is not likely.

    [Edit: Yes, confirmed, it's working again. Thanks!]
