    If fedora 31 comes out with one of the broken kernels(coming soon), I guess we are stuck where we are....

    New Kernel 5.2.9 still the same issues. Now I start to get worried that I still get a black screen. Still on 5.1.20.

    Well, if you look at the bug report: https://bugzilla.kernel.org/show_bug.cgi?id=204325
    It shows it it labeled " Importance: P1 blocking"....

    I thought P1 means that they can't release the next version until it is solved....
    But I guess that is not the next version of 5.2.x - But the first 5.3 version(in about a month)????

    Re: Dispay issues since kernel 5.2.x with Ryzen 3400G | Fedora 30

    Hi everyone. I was about to post a new thread but think I have this same issue. I upgraded my wife's workstation with a AMD motherboard and a SSD HD. F30 live usb and initial install went OK. After a full update I started getting video distortions. The new video card is a Ryzen 5 2400g. I am attaching screenshots shown the distortions and some additional info.

    Can anyone confirm this to be the same issue? Further, there is another thread in this same forum that looks similar:

    Suspecting a kernel problem, I found no way to make the workstation to boot using the original installation kernel in order to wait for a fix, but Plymouth does not allow me to choose the appropriate one. Any advice? Thanks.
    I found out how to boot with the original kernel and the distortions are now gone.

    Are you using nomodeset in your grub.cfg? When I installed F30 on my new HP laptop with Ryzen 3 processor, I had to use the basic graphics to get a screen. After installing though, I was only getting 1024x768 screen resolution. Then I looked at the grub parameters at boot time and noticed that it included nomodeset. I removed that and got a lot better resolution of 1366x68 which looks a whole lot better.

    I was also getting the black screen upon waking up the laptop from suspension. The latest kernel and verifying that the amdgpu kernel module was there seems to have fixed it, bu it is a bit soon to say for sure. I did install xorg-x11-drv-amdgpu-19.0.1-1.fc30.x86_64 which also likely helped.
