• NVMe Erase from the start page lands here and I usually use a Ubuntu LiveUSB to do this, hence the apt command
• TODO: Verify nvme-cli is the package on openSUSE

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

• Could potentially cause a firmware brick or other issues with improper EFI implementations, use at own risk ¹⁴⁾
• Safer way is to use efibootmgr to remove boot entries individually

sudo rm -f '/sys/firmware/efi/efivars/'* || sync && sudo efibootmgr -v

sudo mdadm --detail-platform

• Came from old notes; I assume this worked at some point, but in any case, the syntax looks nice :p

• Use --reduced only for LCD/Non-CRT displays, and only as-needed ¹⁵⁾
• Syntax is horizontal (width), vertical (height) and refresh rate

• 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'

xrandr --verbose | grep *current

• 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

    Modeline x
    Option      "PreferredMode" "3840x2160R"

• The following commands with an asterisk expect only one backlight controller at /sys/class/backlight
