====== Notes ======

  * :!: Anything here expects Xorg and not Wayland
  * ''Identifier'' will need changed for different display connections and drivers

====== Config File ======

  * ''99-graphics.conf''

  sudo mkdir -p '/etc/X11/xorg.conf.d' && sudo -e '/etc/X11/xorg.conf.d/99-graphics.conf'

====== Specific Screens ======

===== Acer S271HL =====

  * See [[devices:acer_s271hl|Acer S271HL]]

  * Last updated: 2022/05/18
  * :!: The ''Identifier'' expects ''modesetting''
  * :!: It's better to [[notes:kernel_parameters#custom_resolution|use a kernel option]] as it applies to both Wayland and Xorg

===== Deep Color =====

  * https://wiki.gentoo.org/wiki/30bpp

  * This may need changed to ''1'' instead for some distros
