This looks suspiciously similar to a bug I'm experiencing on kernel 6.8.0-40 and 6.8.0-45 (Ubuntu 22.04 HWE) i.e.
- keyboard doesn't work at the Luks prompt - Logitech keyboard is plugged in (but even the laptop built-in keyboard stops responding to keypresses when the external keyboard is plugged in) - hybrid intel+nvidia graphics Interestingly, Ctrl+Alt+Del works and allows me to restart the machine. Sometimes it works the second time. Kernel 5.15.0-122-generic (22.04 non-HWE) doesn't have this issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1621367 Title: 4.4.0-36: keyboard dead at boot & full disk encryption prompt for password To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1621367/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
