I performed some additional testing and attached the logs from the failed boot attempts.
Here are the results: Kernel 6.17.0-40 boots successfully with amdgpu.dc=0 produces a black screen without amdgpu.dc=0 Kernel 7.0.0-28 produces a black screen with amdgpu.dc=0 produces a black screen without amdgpu.dc=0 During the black screen the keyboard remained responsive (Caps Lock and Num Lock LEDs were working), but switching to a virtual console with Ctrl+Alt+F1 through Ctrl+Alt+F12 did not work. I had to reboot the system using the reset button. I attached the logs from these failed boot attempts in case they are useful. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2161093 Title: Black screen after boot with kernel 7.0.0-28-generic on AMD Radeon RX 580 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2161093/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
