No need to reinstall after all. In the live USB of 21.04 the bug is present as described. In the live USB of 20.10 and 20.04, it isn't.
So, whatever it is, it's in 21.04, but not in 20.10 or 20.04. I guess this rules out a faulty BIOS. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1926527 Title: "Power off" dialog appears when any three keyboard keys are pressed quickly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1926527/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
