ATA Secure Erase

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

Preparation

sudo zypper install 'hdparm' && sync

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 9)
  • 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
sudo mdadm --create '/dev/md0' --name='RAID' --level='0' --raid-devices='3' '/dev/sda' '/dev/sdb' '/dev/sdc' --verbose

VGA Switcheroo Power States

sudo cat '/sys/kernel/debug/vgaswitcheroo/switch'

ACPI Tables

  • In dsdt.dsl, look for _OSI values, along with Windows and Linux
sudo zypper install 'acpica'
sudo cp --force '/sys/firmware/acpi/tables/DSDT' ~/'dsdt.dat'
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 10)
  • Syntax is horizontal (width), vertical (height) and refresh rate
cvt '3840' '2160' '60'
cvt --reduced '3840' '2160' '60'
--reduced

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

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 notes on how to add backlight changes to a udev script
  • See backlight for more details

Controller Name

ls '/sys/class/backlight'

Query Current Brightness

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'

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'
sudo cat '/sys/kernel/debug/dri/0/i915_guc_load_status'

HT/SMT Information

grep -e "processor" -e "core id" -e "^$" /proc/cpuinfo

Optimal GCC compiler flags

gcc -v -E -x c -march=native -mtune=native - < /dev/null 2>&1 | grep cc1 | perl -pe 's/ -mno-\S+//g; s/^.* - //g;'

Privacy

KDBX to Keybase

cp ~/'Documents/keepass.kdbx' '/keybase/private/espionage724/Documents'

Clear Terminal History

history -cw

Create 7z Password Archive

  • Change 7ZIPNAME in 7ZIPNAME.7z to the desired archive name
  • Change PASS in -pPASS to the desired password
  • Change x to the file or folder to add to the archive
7za a '7ZIPNAME.7z' -p'PASS' 'x'
7za a 'x.7z' -p'x' 'x'

oathtool

  • x is a secret without &digits=6
sudo zypper install 'oath-toolkit'
oathtool --totp -b 'x'

Remove EXIF data

sudo zypper install 'exiftool'
exiftool -all= *.* -overwrite_original
4)
these notes mostly work with Xfce also
5)
EFI file to boot and in the case of Acer laptops, add to SecureBoot trust; doesn't matter if SecureBoot is enabled or not
6)
the imported key gets referenced once the keybase package downloads through zypper, before its installation
7)
currently not NVIDIA proprietary drivers; maybe Intel in the future
8)
eg: R600/Radeon HD 6000 Series
9)
personally tested fine on several Acer and Dell computers
10)
useful for reducing amount of bandwidth over cables, particularly in-case of unstable 4k@60Hz set-ups
