Dual Boot with Fingerprint Scanner Issues

https://community.frame.work/t/fingerprint-scanner-compatibility-with-linux-ubuntu-fedora-etc/1501/206

The script below will clear the existing fingerprints from the internal storage.

#! /usr/bin/python3

import gi
gi.require_version('FPrint', '2.0')
from gi.repository import FPrint

ctx = FPrint.Context()

for dev in ctx.get_devices():
    print(dev)
    print(dev.get_driver())
    print(dev.props.device_id);

    dev.open_sync()

    dev.clear_storage_sync()
    print("All prints deleted.")

    dev.close_sync()

Backup Disks

Backup disks will respect the following naming convention:

brand_size_purpose_year_month

So for a backup drive you would create:

wd_4tb_backup_2023_01

Or for an archive drive:

samsung_1tb_archive_2023_01

Restore

In the event you need to restore your system from a disaster do the following:

Reinstall fedora via a live image
After install, disk should be mounted at /mnt/sysimage
Copy the new fstab and crypttab to somewhere safe
rsync -av [etc, home, opt, root, usr, var]
mount /dev/Y /mnt/sysimage/boot
mount /dev/Z /mnt/sysimage/boot/efi
mount --bind /dev /mnt/sysimage/dev
mount --bind /proc /mnt/sysimage/proc
mount --bind /sys /mnt/sysimage/sys
chroot /mnt/sysimage
Edit fstab and crypttab so they match the new partitions
Update /etc/default/grub to match the new luks uuid
grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
reboot

Firewall CMD

Enable firewall

systemctl start firewall-cmd
systemctl enable firewall-cmd

Set default behavior to drop everything

firewall-cmd --set-default-zone=drop
systemctl reload firewall-cmd

Bluetooth

Airpods

Edit: /etc/bluetooth/main.conf Set ControllerMode = bredr

restart bluetooth service
connect airpods
comment line out
restart bluetooth service again

zram-size = min(ram / 2, 16384)
compression-algorithm = lzo-rle
options =
writeback-device = /dev/zvol/tarta-zoot/swap-writeback

Automatic Disk Decryption with TPM2

It's a friendlier experience to just encrypt your root partition with tpm and lunlock your remaining drives with key files stored at /etc/ukskeys. This way you only need to reregister one key with your tpm and the remaining drives will be unlocked automatically.

Add your luks keys to the tpm module and set up boot parameters:

# Enroll for the first time
sudo -E systemd-cryptenroll --tpm2-device=auto --tpm2-pcrs=0+2+4+7 /dev/nvme1n1p3

# Add tpm2 configuration option to /etc/crypttab
# You can get the uuid with lsblk and blkid
luks-d9828faa-2b8c-4184-9e74-9054ae328c6d UUID=d9828faa-2b8c-4184-9e74-9054ae328c6d none tpm2-device=auto,discard

# Add rd.luks.options=tpm2-device=auto to grub
sudo grubby --args="rd.luks.options=tpm2-device=auto" --update-kernel=ALL

# Regenerate the boot parameters
sudo dracut -f

We can configure our system to automatically reenroll the tpm device on boot so you only need to enter your password on kernel updates.

# Create a new random password for your disk
sudo cryptsetup luksAddKey /dev/nvme0n1p3

/etc/systemd/system/tpm_luks_cryptenroll.service

[Unit]
Description=Automatically runs systemd-cryptenroll on login

[Service]
Type=oneshot
ExecStart=/usr/bin/systemd-cryptenroll --tpm2-device=auto --tpm2-pcrs=0+2+4+7 --wipe-slot=tpm2 /dev/nvme0n1p3
# new random password you just created
Environment=PASSWORD=

[Install]
WantedBy=multi-user.target

# Now enable the service
sudo systemctl enable tpm_luks_cryptenroll.service

Firefox GPU Rendering

https://community.frame.work/t/linux-battery-life-tuning/6665

dnf install intel-media-driver intel-gpu-tools

Type in about:config in the address bar and hit enter.

Set media.rdd-ffmpeg.enabled, media.ffmpeg.vaapi.enabled and media.navigator.mediadatadecoder_vpx_enabled to true.

Close and reopen your browser

Run the command sudo intel_gpu_top, play a 4k video and check whether the Video section is above 0.00%

Gnome Software Updates (packagekitd and software)

To prevent Gnome Shell from starting Software open Settings->Search and disable Software from there.

Disable auto-updates

sudo systemctl disable packagekit
sudo systemctl stop packagekit

dconf write /org/gnome/software/allow-updates false
dconf write /org/gnome/software/download-updates false

Turn Off Fingerprint When Laptop Lid Closed

To disable fingerprint authentication when the laptop lid is closed, and re-enable when it is reopened, we will use acpid to bind to the button/lid.* event to a custom script that will stop and mask the fprintd service on lid close, and unmask and start the fprintd service on lid open.

We also check that the HDMI cable is connected by testing the contents of /sys/class/drm/card0-HDMI-A-1/status.

Follow the steps below:

Create a .locks file in your home dir: mkdir ~/.locks

Create file /etc/acpi/laptop-lid.sh with the following contents:

#!/bin/bash

lock=/home/ducoterra/.locks/fprint-disabled.lock

if grep -Fq closed /proc/acpi/button/lid/LID0/state # &&
    # This is used to detect if a display is connected.
    # For USB C displayport use: 
    # grep -Fxq connected /sys/class/drm/card1-DP-2/status
    # For hdmi use:
    # grep -Fxq connected /sys/class/drm/card0-HDMI-A-1/status
then
    touch "$lock"
    systemctl stop fprintd
    systemctl mask fprintd
elif [ -f "$lock" ]
then
    systemctl unmask fprintd
    systemctl start fprintd
    rm -f "$lock"
fi

Make the file executable with

chmod +x /etc/acpi/laptop-lid.sh
Create file /etc/acpi/events/laptop-lid with the following contents:
```
event=button/lid.*
action=/etc/acpi/laptop-lid.sh
```
Restart the acpid service with:

sudo service acpid restart

Now the fingerprint will be used only when the lid is open.

In order to restore the correct state of the fprintd service if you disconnect/reconnect while the laptop is off, you may call the above script from a systemd init file. The steps to do this are the following:

Create a file named /etc/systemd/system/laptop-lid.service with the following contents:

[Unit]
Description=Laptop Lid
After=suspend.target

[Service]
ExecStart=/etc/acpi/laptop-lid.sh

[Install]
WantedBy=multi-user.target
WantedBy=suspend.target

Reload the systemd config files with

sudo systemctl daemon-reload
Start the service with

sudo systemctl start laptop-lid.service
Enable the service so that it starts automatically on boot

sudo systemctl enable laptop-lid.service

Now the status should be correct even after connecting/disconnecting when the computer is off.

Power Button Behavior

The power button is controlled from 2 locations:

DCONF (or gnoem settings) at gnome.settings-daemon.plugins.power
ACPI at /etc/acpi/events/powerconf

The powerconf acpi configuration will execute at the same time the gnome settings do. This can lead to situations where the gnome settings say "suspend" but the acpi settings say "shutdown". On waking up your laptop it will immediately shutdown.

The solution is to comment out everything in /etc/acpi/events/powerconf and rely on the gnome settings OR set the gnome settings to "nothing" and edit /etc/acpi/actions/power.sh with the behavior you expect. Either way you should pick one to control power button behavior.

THIS IS PROBABLY A PER-APP THING

Likely the thing you're trying to share doesn't work, it's not wayland's fault.

If you're trying to share firefox - download the firefox binary and dnf uninstall the other one. For whatever reason the preinstalled binary doesn't like screen share. You can use the following:

~/.local/share/applications/firefox.desktop

[Desktop Entry]
Encoding=UTF-8
Name=Firefox
Exec=/home/ducoterra/Applications/firefox/firefox-bin
Icon=/home/ducoterra/.icons/firefox.svg
Type=Application
Categories=Browser;

Minecraft

You can find extra java versions at /etc/alternatives
You need to dnf install xrandr to launch any modpacks
You can create a desktop icon by putting this at ~/.local/share/applications/*.desktop:

[Desktop Entry]
Type=Application
Version=1.0
Name=Minecraft
Comment=Minecraft Launcher
Path=/home/ducoterra/Applications
Exec=minecraft-launcher
Icon=/home/ducoterra/Icons/minecraft-launcher.png
Terminal=false
Categories=Games;

Sound Devices

If you want to disable a specific device or tell Fedora not to use a specific device as output or input (looking at you yeti microphone, you're not a speaker), you can install pulse audio control for much more fine-tuned... control.

Setting your speakers to analog output seems to work best for a USB dac if it has a separate volume knob since this ties the volume knob on the dac to the internal volume of your computer.

Setting your mic to analog input works just fine on a yeti usb mic.

sudo dnf install pavucontrol

Install ffmpegthumbnailer, remove totem

totem-thumbnailer crashes all the time and isn't as good as ffmpeg's thumbnailer. What's more, totem video player ("Videos" by default on gnome) is not as good as vlc and doesn't work very well for anything more than basic video playback.

sudo dnf remove totem
sudo dnf install ffmpegthumbnailer

Add compatibility for HEIC to mogrify

sudo dnf install libheic-freeworld
