I have now tested whether the issue is still resolved and it luckily is. So both after installing a version of amdgpu-pro and also after uninstalling this proprietary driver again, unlocking the system works again.
Once the stable version of Ubuntu 22.04 is published, I will upgrade and try again. At this point, I don’t want to try a pre-release version to avoid having my only personal computer become inoperable. Also, I have yet to find a way to restore the resolution during the boot process. Specifically, the default resolution is used during the cryptsetup decryption stage and before (when only the mainboard manufacturer logo is shown). The BIOS configuration seems to be in order and is set to use the primary PCIe slot to which my monitor is connected. It’s not terrible that this is so, but I’d like to fix it. My internet searches have been unsuccessful though. -- 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/1964711 Title: [amdgpu] Locked Ubuntu is frozen and cannot be unlocked Status in linux-hwe-5.13 package in Ubuntu: Incomplete Bug description: After locking Ubuntu and leaving it unattended for a while, the operating system cannot be unlocked anymore. No means of user input (e.g. typing on the keyboard, moving the mouse) produce the lock screen and I have to shut down my computer by pressing down the power button. The attached monitor does not receive a signal from the computer during these attempts. This started to happen several weeks ago and worked without a problem before then. Due to the nature of this issue, I can neither report any errors occurring nor can I observe any other out of the ordinary things from happening. Thus, I don’t know which package is causing the issue. Also, this issue happens every time I leave the computer unattended for a longer time and lock it. However, locking it and triggering an input immediately after does produce the lock screen, so the lock screen seems to work in principle.
