Thanks. It seems the issue is that the kernel graphics driver failed to initialize:
Jul 04 09:52:48 loonix kernel: amdgpu 0000:05:00.0: amdgpu: amdgpu_device_ip_init failed Jul 04 09:52:48 loonix kernel: amdgpu 0000:05:00.0: amdgpu: Fatal error during GPU init Jul 04 09:52:48 loonix kernel: amdgpu 0000:05:00.0: amdgpu: amdgpu: finishing device. and then it crashed. So a black screen is expected... The next thing to try is to choose a kernel version older than 5.15.0-113.123-generic at startup. You can do that by accessing the grub menu. Soon after you see the BIOS logo when rebooting, tap Escape once, and that should give you the grub menu. There you can select the previously installed kernel version. Another thing to try is to change the machine over to the hardware enablement kernel. Assuming you have network access in recovery mode, run: sudo apt install linux-generic-hwe-22.04 Hopefully that will fix it. ** Package changed: ubuntu => linux (Ubuntu) ** Summary changed: - Black screen freeze + [amdgpu] Black screen freeze ** Tags added: amdgpu ** Tags added: regression-update -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2071702 Title: [amdgpu] Black screen freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2071702/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
