I am seeing this same issue (static screen) on a fully updated Jammy system. It is a Beelink Renoir system and I have two external monitors plugged in via HDMI.
It seems to happen fairly randomly, but most often after the monitors go to sleep and then are woken up. It resolves itself eventually and doesn't seem to reoccur as long as I'm active on the system. Only one of the screens will go into static when it happens. Manually cycling power on a monitor can help bring it back. Currently on kernel 5.19.0-41-generic. Any workarounds or fixes? Currently using Xorg display, haven't tried Wayland yet. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe-5.13 in Ubuntu. https://bugs.launchpad.net/bugs/1958523 Title: [amdgpu] Static-noise-like effect Status in linux-hwe-5.13 package in Ubuntu: Confirmed Bug description: Hello, I have encountered a bug in Ubuntu. When I turn on my laptop and log in (I can see the login screen) I see static-noise-like effect. I was able to make a screenshot and it depicts my desktop as if the problem didn't exist. Switching to stable (non-HWE) kernel solves the issue. My desktop environment is GNOME.
