• Both commands do the same things

df -hT

df --human-readable --print-type

sudo cryptsetup -v status '/dev/dm-0'

• 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

sudo hdparm --user-master u --security-set-pass 'x' '/dev/sda' && sudo hdparm --user-master u --security-erase '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 ¹²⁾
• 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

• In dsdt.dsl, look for _OSI values, along with Windows and Linux

sudo dnf install 'acpica-tools'

sudo cp --force '/sys/firmware/acpi/tables/DSDT' ~/'dsdt.dat'

cd ~ && iasl -d ~/'dsdt.dat'

gio open ~/'dsdt.dsl'

sudo dnf remove 'acpica-tools' && sync

• Use --reduced only for LCD/Non-CRT displays, and only as-needed ¹³⁾
• Syntax is horizontal (width), vertical (height) and refresh rate

cvt '3840' '2160' '60'

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

--reduced

• 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 --addmode 'HDMI-A-0' '3840x2160R'

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

Section "Monitor"
    Identifier  "HDMI-A-0"
    Modeline x
    Option      "PreferredMode" "3840x2160R"
EndSection

• 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

echo "376" | sudo tee '/sys/class/backlight/'*'/brightness' > '/dev/null'

echo "$(cat '/sys/class/backlight/'*'/max_brightness')" | sudo tee '/sys/class/backlight/'*'/brightness' > '/dev/null'

• Change PASS in -pPASS to the desired password
• Change x to the file or folder to add to the archive
