There is something I remember which may influence the bug. Usually when there is a new kernel I do an immediate restart. Yesterday after I was done updating to the new kernel, I had nothing more to do on the computer. Thus instead of a Restart I did a Shut down. This morning when I turned on the computer I got the blank screen problem.
Could that have a connection to the problem? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1474342 Title: 3.19.0-22 won't display on Lenovo To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2-signed/+bug/1474342/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
