Same problem here after updating from 5.15.0-157 to 5.15.0-160; reverting to -157 fixes.
CPU is an AMD64 ryzen 5 5600G, with builtin graphics only (no discrete GPU) connected via displayport. Image is normal during BIOS post as well as for the grub menu, but lost immediately after, with the monitor's software indicating it's going into standby because no input is detected anymore. My system requires a password to unlock the root drive, but the screen goes black even before the prompt for that shows up. So whatever the issue, something is going off the rails very early on. It isn't completely hung though, as pressing crtl-alt-del still makes it reboot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2128729 Title: Kernel 5.15.0-160 boots without any video output (on AMD) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2128729/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
