• All hdparm commands below assume actions to be performed on /dev/sda

sudo dnf install 'hdparm' && sync

sudo hdparm -I '/dev/sda'

systemctl suspend

sudo blkdiscard --verbose '/dev/sda'

sudo hdparm --user-master u --security-set-pass 'x' '/dev/sda' && sudo hdparm --user-master u --security-erase-enhanced 'x' '/dev/sda' && sync

• 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 dnf 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 ¹⁵⁾
• 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

sudo mdadm --create '/dev/md0' --name='RAID' --level='0' --raid-devices='3' '/dev/sda' '/dev/sdb' '/dev/sdc' --verbose

• Use --reduced only for LCD/Non-CRT displays, and only as-needed ¹⁶⁾
• Syntax is horizontal (width), vertical (height) and refresh rate

cvt --reduced '3840' '2160' '60'

• Changes are lost after reboot
• Values after --newmode are from the above generate command, and is everything after Modeline

xrandr --output 'HDMI-A-0' --mode '3840x2160R'

• 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
• This was only tested on one laptop with intel_backlight
• See Power Management notes on how to add backlight changes to a udev script
• See backlight for more details

ls '/sys/class/backlight'

cat '/sys/class/backlight/'*'/brightness'

cat '/sys/class/backlight/'*'/max_brightness'

• Change 376 to desired brightness
• Desired brightness must be under max_brightness value
