The issue happened again after installing another package update. The updated packages were:
krb5-locales libgif7 libgssapi-krb5-2 libk5crypto3 libkrb5-3 libkrb5support0 I am no longer using the amdgpu.dc=0 kernel parameter. It has been completely removed from my GRUB configuration. I am currently running the latest available kernel (7.0.0-28-generic). Immediately after installing the updates and rebooting, the system again booted to a black screen. Reconnecting the monitor cable to the graphics card did not help this time. I had to perform a hard reboot using the reset button on the PC case. After the hard reboot, the system started normally and has continued to boot normally on subsequent cold boots and reboots. This is now the second time I have observed the same pattern: install package updates; first reboot → black screen; perform a hard reboot; subsequent boots work normally until another package update triggers the issue again. -- 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
