Thank you for your very quick and helpful guidance, Daniel. I will sleep far easier in the future, my eyes now spared from blue light! The contents of prevboot.txt contained the following pertinent excerpt:

Closing log file. I followed this advice and added a Driver "synaptics" line to /etc/X11/xorg.conf.d/30-touchpad.conf. I also ran sudo apt install xserver-xorg-input-synaptics and then rebooted successfully into X11. My speculation is that the version of X11 in use on Ubuntu 21.10 probably warned rather than crashed when the driver was not specified, most likely defaulting to synaptics. I suspect that when I upgraded to Ubuntu 22.04, the new version of X11 I received made specifying the driver mandatory. Wayland requires the libinput driver, and the synaptics driver presumably is no longer even installed by default. The one remaining mystery to me is that the gear to switch between X11 and Wayland still doesn't show up at the login screen. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1977695 Title: Black Screen on Boot with X11 Status in xorg-server package in Ubuntu: Incomplete Bug description: Description: Ubuntu 22.04 LTS Release: 22.04 xorg: Installed: 1:7.7+23ubuntu2 Candidate: 1:7.7+23ubuntu2 Version table: *** 1:7.7+23ubuntu2 500 500 http://us.archive.ubuntu.com/ubuntu jammy/main amd64 Packages 100 /var/lib/dpkg/status 1. Uncomment WaylandEnable=false in /etc/gdm3/custom.conf 2. Reboot. 3. See black screen after selecting Ubuntu at GRUB prompt. Login screen never loads. Unplugging any external monitors appears to have no effect on the bug. I am aware that most users of Ubuntu 22.04 see an option at the login screen to change the display manager. I have never seen such an option. My machine always uses Wayland unless I modify /etc/gdm3/custom.conf directly. Using Wayland is detrimental to my health, because the Night Light feature does nothing. I have nvidia- driver-510 installed. I am happy to provide further debugging information upon request.
