The OS loads as normal and my external monitor still works, but my laptop monitor does not. I was able to fix the problem by pressing ESC as soon as the HP logo appears during start-up, then selecting "Advanced Ubuntu Options", then choosing an older version of Ubuntu (currently that's ...5.4.0-48..., while I believe the latest version is ...5.8.0-66...). It seems clear that this problem is caused by a bug that was introduced in one of the more recent updates (...5.8.0-59..., maybe?). I am not at all sure that the problem is in xorg; the package identification webpage just suggested that, if the monitor is blank when I would expect to see the Ubuntu logo during startup, then I should say that the relevant package is xorg. I am more than happy to run additional diagnostics that you would recommend if that would help you diagnose and fix the problem. Thank you.
