 +
 +==== Preparation ====
 +
 +  sudo dnf install 'hdparm' && sync

 +  sudo hdparm -I '/dev/sda'
 +
 +  sync && systemctl suspend

 +
 +===== 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 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 dnf remove 'acpica-tools' && sync
 +
 +===== Display EDID Info =====

 +  * https://unix.stackexchange.com/a/114398
 +
 +  sudo dnf install 'monitor-edid'
 +
 +  monitor-edid
 +
 +===== 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 --addmode 'HDMI-A-0' '3840x2160R'
 +
 +  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"
 +EndSection</code>
 +
 +===== 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

 +  * Change ''376'' to desired brightness
 +  * Desired brightness **must** be under ''max_brightness'' value
 +
 +  echo "376" | sudo tee '/sys/class/backlight/'*'/brightness' > '/dev/null'
 +
 +==== Set Max Brightness ====
 +
 +****
 +
 +  echo "$(cat '/sys/class/backlight/'*'/max_brightness')" | sudo tee '/sys/class/backlight/'*'/brightness' > '/dev/null'
 +
 +===== Intel GuC Firmware =====
 +
 +  sudo cat '/sys/kernel/debug/dri/0/i915_guc_info'
