to remove boot entries individually
sudo rm -f '/sys/firmware/efi/efivars/'* || sync && sudo efibootmgr -v
RAID
Controller Details
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 withWindows
andLinux
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

Custom Resolutions
Generate Modeline
- Use
--reduced
only for LCD/Non-CRT displays, and only as-needed 13) - Syntax is
horizontal
(width),vertical
(height) andrefresh 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 afterModeline
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

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 "$(cat '/sys/class/backlight/'*'/max_brightness')" | sudo tee '/sys/class/backlight/'*'/brightness' > '/dev/null'
Intel GuC Firmware
sudo cat '/sys/kernel/debug/dri/0/i915_guc_info'
sudo cat '/sys/kernel/debug/dri/0/i915_guc_load_status'
Hyper-threading Information
grep -e "processor" -e "core id" -e "^$" /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
Clear Terminal History

Create 7z Password Archive
- Change
7ZIPNAME
in7ZIPNAME.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

sudo dnf install 'oathtool'

Remove EXIF data
sudo dnf install 'perl-Image-ExifTool'
exiftool -all= *.* -overwrite_original
2)
EFI file to boot and in the case of (quirky) InsydeH2O UEFI implementations, add to SecureBoot trust; doesn't matter if SecureBoot is enabled or not
3)
Spinesnap
4)
defaults,discard
5)
if grep reports nothing, use whatever is reported instead
6)
modesetting
has a 4K RB resolution without any settings on Xorg7)
GpuTest's fur ring doesn't render right, RS's NXT client's splash screen is gray
8)
HD6000 series and lower, and non-SI HD7000 series
9)
see
modinfo -p amdgpu
12)
personally tested fine on several Acer and Dell computers
13)
useful for reducing amount of bandwidth over cables, particularly in-case of unstable 4k@60Hz set-ups
