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.

==== Better Screen Fix ====

The Debian 6.6.8-1 (2023-12-22) x86_64 GNU/Linux kernel from sid, seems to correct the screen problems

  * Add the sid repo to /etc/apt/sources.list
    * deb http://deb.debian.org/debian/ sid main contrib non-free-firmware non-free
    * deb-src http://deb.debian.org/debian/ sid main contrib non-free-firmware non-free
  * apt-get update
  * apt-get -y install linux-image-6.6.8-amd64
  * Comment out the above enties in sources.list
