Update 2023-12-26
After a few weeks of heavy use
The half-screen after sleep/hibernate/low-power/screen-dim issue is pretty brutal. What would happen is on wakeup the screen would split in two the bottom half would be a blurry mess that seemed to clean up as you typed frantic xrandr commands to try and get it sane. I went so far as to create a hot-key ctrl-alt-f that made the xrandr call I could bang easily sometimes requiring 5 or more tries until the screen was sane. With the installation of the SID kernel (Debian 6.6.8-1 (2023-12-22) x86_64 GNU/Linux) this issue appears to have been resolved.
So I will be updating a few things below, but as of now I am actually happy with this machine running vanilla debian with a number of tweaks. I have *everything* working and the latest kernel from SID seems to have resolved the crazy half-screen pixellation issue.
