Comments/Problems:
Upon booting Debian from GRUB I was greeted with a blank screen. The monitor
turned off because it didn't have signal. I could not even start a CLI using
ctrl+alt+F-keys.
After some research, I added "nomodeset" to the Linux boot options and was able
to get to the login screen. Wayland did not work. X11 did. I did a lot of research
to find out what was going on. I broadened my package source list to include non-
free, etc. I checked the AMDGPU package, it was installed, the Linux non-free firmware was
installed. These things did not seem to help, although they might have in the long run.
At the end of my research, I learned about how the AMD graphics drivers are
built into the kernel. Therefore, I resolved to install a newer semi-safe kernel, the
current backport, 6.6.13+bpo-amd64. After that I could launch Debian and reach
the Wayland iteration of KDE at the highest resolution that my monitor could support
without "nomodeset"

be useful are attached to this report. (You can find them in the
installer system in /var/log/ and later on the installed system
under /var/log/installer.) Please compress large files using gzip.
