Ubuntu notified me that a software update was available, and that I would need to reboot to complete the update. I went for it. I was told that the updates had downloaded, and was given the option to install. After selecting install (twice), and getting back to the same options, I decided to reboot. Bad choice.
The resolution was terrible. Power cycling didn't help. Also no internet. And there were a couple of lines extra lines on the grub page: Instead of replacing the Ubuntu and Ubuntu (Advanced Options) lines, new lines were added.
Aside: I also dual boot into windows.
I booted using an "advanced option" - using the previous kernel: 5.11.0.38 . . . , if that is right terminology. Resolution good, internet works.
Suggested repairs?
Clue: I tried updating and upgrading, and . . .
