Problems with screen randomly going black on f42

Ask Fedora

On Monday I did a dnf update and upgraded to all the latest packages (except vnc), which gave me kernel-6.15.3-200.fc42.x86_64. After I rebooted I had problems with the screen going randomly going black. When this happens I have to ssh in from another computer, run “systemctl suspend”, and wake the computer up. This restores the video for a while.

After finding this thread I thought my problem might be related, so I did a “dnf update --refresh” which gave me kernel-6.15.4-200.fc42.x86_64, but it still didn’t solve my problem, so I rebooted back into kernel-6.14.9-300.fc42.x86_64 but the problem still hasn’t gone away.

So my questions are

  1. How do I debug this? Nothing appears in the logs or dmesg output

  2. is there any way to reset the video besides suspending the system and reawakening it?

I’m running on an AMD Ryzen 7 5700G

Have you seen the following comment from that thread which was posted on 30th June and accepted as the solution?

Try upgrading your system again and see if it fixes the problem.

Again I totally updated, except for the broken vlc packages.
