Some additional information on my system with AMD Ryzen 5 8600G w/ Radeon 760M Graphics.
This is a new system originally installed with Ubuntu 23.10 which worked ok. After upgrading to 24.04 the same thing started happening: blank screen after boot. Works when booted from 24.04 live USB, but after installation I could not figure out permanent fix for blank screen. It does work in safe mode (nomodeset), but of course quite slowly. When I installed SSH server in safe mode and rebooted back to blank screen, I could login remotely even though the system looked dead. Nothing stood out in the logs, looked like the system thought it was working normally. Magic sysrq also works. I went back to 23.10 for now, but a couple of week old logs from booting 24.04 are available if they might be useful. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2063983 Title: 24.04 Upgrade/Fresh Install results in black screen on reboot on AMDGPU system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2063983/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
