If I leave my system at the login screen, the monitors will go to sleep and then I cannot wake the monitors with mouse or keyboard.
Can someone please look at this report? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1999189 Title: Displayport monitors hang on blanking and must REISUB my 20.04.5 system Status in linux package in Ubuntu: Confirmed Bug description: I've been getting issues with my 2 DP monitors (and system) not recovering from blanking (possibly 100% of the time). If I disable blanking, the issue never occurs. Otherwise, I am forced to REISUB the system to regain access. As I'm using amdgpu from the HWE kernel, my best guess is thats where the issue lies. When the issue occurs I am completely unable to access the system due to a softlock and CPU getting maxed by Xorg. SSH barely works and the system doesn't respond to request to perform dumps like Alt- PrintScreen-1. The only relevant output I have seen (as a user) is in syslog, and possibly dmesg. In addition, when I try to submit an apport-bug it fails (multiple times). Here is the Error ID: OOPS-108b77945d65b4a0f23eba000f0d8a8e while trying to wait for the launchpad page to process my data. Finally, as I'm more of a user, I can only likely manage to test anything with some decent instructions. This issue has been going on for a few weeks, and due to a recent hardware change I cannot confirm if there was a time when my current system did not have the issue.
