-  * :!: All ''hdparm'' commands below assume actions to be performed on ''/dev/sda''
-==== Preparation ====
-  sudo zypper install 'hdparm' && sync
-  sudo hdparm -I '/dev/sda'
-  sync && systemctl suspend
-==== ATA Secure Erase ====
-<code>sudo blkdiscard --verbose '/dev/sda'</code>

-===== NVMe Erase =====
-  * NVMe Erase from the start page lands here and I usually use a Ubuntu LiveUSB to do this, hence the ''apt'' command
-  sudo apt install 'nvme-cli' -y && sync
-  sudo zypper install 'nvme-cli' -y && sync
-  sudo nvme format '/dev/nvme0' --reset --ses='1' --pil='0' --pi='0' --ms='0' && sync
-===== Clean EFI Variables =====
-  * :!: Could potentially cause a firmware brick or other issues with improper EFI implementations, use at own risk ((personally tested fine on several Acer and Dell computers))
-  * Safer way is to use ''efibootmgr'' to remove boot entries individually
-  sudo rm -f '/sys/firmware/efi/efivars/'* || sync && sudo efibootmgr -v
-===== RAID =====
-==== Controller Details ====
-  * This can be used to get the Oprom version for Intel RST
-  sudo mdadm --detail-platform
-==== Create Software RAID ====
-  * :?: Came from old notes; I **assume** this worked at some point, but in any case, the syntax looks nice :p

-===== ACPI Tables =====
-  * In ''dsdt.dsl'', look for ''_OSI'' values, along with ''Windows'' and ''Linux''
-  sudo zypper install 'acpica'

-  cd ~ && iasl -d ~/'dsdt.dat'
-  gio open ~/'dsdt.dsl'
-  sudo zypper remove 'acpica' && sync
-===== Custom Resolutions =====
-==== Generate Modeline ====
-  * Use ''--reduced'' only for LCD/Non-CRT displays, and only as-needed ((useful for reducing amount of bandwidth over cables, particularly in-case of unstable 4k@60Hz set-ups))
-  * Syntax is ''horizontal'' (width), ''vertical'' (height) and ''refresh rate''
-  cvt '3840' '2160' '60'
-  cvt --reduced '3840' '2160' '60'
-<code>--reduced</code>
-==== Temporarily Apply ====
-  * Changes are lost after reboot
-  * Values after ''--newmode'' are from the above generate command, and is everything after ''Modeline''
-  xrandr --newmode "3840x2160R"  533.00  3840 3888 3920 4000  2160 2163 2168 2222 +hsync -vsync

-  xrandr --output 'HDMI-A-0' --mode '3840x2160R'
-=== Verify ===
-****
-  xrandr --verbose | grep *current
-==== Permanently Apply ====
-  * ''Identifier'' is the name of the port on the GPU the display is connected to
-  * ''Modeline'' is from the above generate command, including the text ''Modeline''
-  * ''PreferredMode'' is the custom resolution name generated
-<code>
-Section "Monitor"
-    Identifier  "HDMI-A-0"
-    Modeline x
-    Option      "PreferredMode" "3840x2160R"

-===== Backlight =====
-==== Notes ====
-  * The following commands with an asterisk expect only one backlight controller at ''/sys/class/backlight''
-  * This was only tested on one laptop with ''intel_backlight''
-  * See [[#power_management|Power Management notes]] on how to add backlight changes to a udev script
-  * See [[https://wiki.archlinux.org/index.php/backlight|backlight]] for more details
-==== Controller Name ====

-  cat '/sys/class/backlight/'*'/brightness'
-==== Query Max Brightness ====
-****
-  cat '/sys/class/backlight/'*'/max_brightness'
-==== Set Custom Brightness ====
-  * Change ''376'' to desired brightness
-  * Desired brightness **must** be under ''max_brightness'' value
-  echo "376" | sudo tee '/sys/class/backlight/'*'/brightness' > '/dev/null'
