Fedora 36 (Nobara) Black Screen with AMD Radeon 6600 after Update

Hi all,

I am having trouble with my Fedora 36 after upgrade to new kernel kernel-5.19.6-202.fsync.fc36.x86_64 (from kernel-5.19.4-201.fsync.fc36.x86_64 which also gave the same issue)
I’m running an AMD Radeon RX 6600 on 4x monitors.
There is no login screen, just black screen, sometimes with mouse pointer, sometimes without.

I can log in without issue if I use a previous kernel-5.18.19-201.fsync.fc36.x86_64
But anything after that, kernel-5.19.4-201.fsync.fc36.x86_64 and kernel-5.19.6-203.fsync.fc36.x86_64 gives me a black screen.

Here is a list of the current kernels available on my machine:

[linux@192-168-###-### ~]$ rpm -qa kernel
kernel-5.18.19-201.fsync.fc36.x86_64
kernel-5.19.6-202.fsync.fc36.x86_64
kernel-5.19.6-203.fsync.fc36.x86_64

Any ideas how to resolve this problem?

What is this tag for? Have you been compiling and installing your own kernels? I don’t seem to have any of those patch versions here:

$ rpm -q kernel
kernel-5.18.17-200.fc36.x86_64
kernel-5.18.18-200.fc36.x86_64
kernel-5.18.19-200.fc36.x86_64
kernel-5.19.4-200.fc36.x86_64
kernel-5.19.6-200.fc36.x86_64

What is the output of rpm -qi kernel?

Hi Scott,

I have not been compiling and installing my own kernels, these are kernels made by Glorious Eggroll (Thomas Crider) who is the brains at Redhat/Proton, has been making these for the Nobara project version of fedora 36.

Note: I managed to get it running but its intermittent, sometimes it boots up sometimes it doesn’t, but in order to make it boot, I have to first, on boot, do and edit (E) on the grub screen and add nomodeset, then boot up from there… then reboot after that back to normal then it will work. If I reboot it again after that without using the nomodeset hack, it will go to black screen so its obvious somewhere there is an issue with the graphics because it happens on both nvidia and amd and its not their drivers either, its something to do with the kernel updates and it happens on almost every kernel update. I’ve seen many posts here that include this same problem, often people claiming its the nvidia drivers, but its not because it also happens on amd as well and there has been a hack made by a contributor here named Jeff that seems to fix some of it. Nothing to do with the graphics drivers.

Here is the output as requested:

Cheers

That can be fixed as a permanent solution by editing /etc/default/grub and adding that option into the kernel command line. Once the edit has been saved it can be updated into the boot loader with grub2-mkconfig -o /boot/grub2/grub.cfg. After editing that file the change will remain for updates until you do a complete new install that wipes out that file and replaces it.

That “hack” as you called it is actually a permanent fix for your system. Depending upon the hardware involved some need the modeset and some do not so it is difficult to actually provide an install method that works for everyone.

Unfortunately if I make it a permanent solution by editing the grub.cfg, then I will not be able to set the screen resolution properly and its stuck at 800. I’m not sure why but once you reboot from that and go back to the original configuration, I’m able to log in again.

UPDATE: There has been a new update on the kernel (kernel-5.19.7-202.fsync.fc36.x86_64) for which the problem has now been resolved. Obviously this issue is very common on each kernel update and is always affecting the graphics.

The problem is, by this kind of thing happening, it ruins the great original experience one has with Fedora, especially for those that are new to the Fedora/Linux scene… Hopefully in the future, when kernels are updated and compiled, the graphics side of thing is checked properly before the update is released because nobody is really in a hurry to get the latest kernel, but when you do a dnf update or install software, and the updates appear, the most logical and rational thing would be to accept the updates so that your rig is working at its optimal, always trusting that those updates have been thoroughly tested, which unfortunately they aren’t, thus resulting in a black screen login… which then causes the user to get very frustrated with the operating system. Hopefully things change now and updates are released with a lot more caution.

Hey there. We are a community distribution and this kind of testing depends on users like you testing it out on their own hardware. This is a great simple way for you to help contribute to make Fedora better for yourself and other users with similar hardware as well. Please consider helping us vet future kernels:

No problem, I am very happy to help give feedback and with the testing of kernels, I use Fedora as a daily machine, I use it for 99% of the things I do and I’ve been using Linux (all sorts of distros) for the last 15 years at least… Fedora has always been the best by far. :bluethumb:
