ThinkPad T480 fingerprint reader on Fedora Linux

Background

The Synaptics fingerprint sensor (06cb:009a) present on my T480 is not supported by libfprint and fprintd as it requires a non-free binary blob. uunicorn created open-fprintd, a replacement for fprintd, that allows for loading of binary blobs. In conjunction with their python-validity driver we are able to make use of the inbuilt fingerprint reader. The following instructions were tested against Fedora Linux 35.

Installing `open-fprintd` and `python-validity`

sudo dnf copr enable tigro/python-validity
sudo dnf install open-fprintd fprintd-clients fprintd-clients-pam python3-validity

Note: this was tested and used on DSM5 and partly on 6. Since V7 I am not using this anymore.

Got and ssh into your box. Find what is using swap:

find /proc -maxdepth 2 -path "/proc/[0-9]*/status" -readable -exec awk -v FS=":" -v TOTSWP="$(cat /proc/swaps | sed 1d | awk 'BEGIN{sum=0} {sum=sum+$(NF-2)} END{print sum}')" '{process[$1]=$2;sub(/^[ \t]+/,"",process[$1]);} END {if(process["VmSwap"] && process["VmSwap"] != "0 kB") {used_swap=process["VmSwap"];sub(/[ a-zA-Z]+/,"",used_swap);percent=(used_swap/TOTSWP*100); printf "%10s %-30s %20s %6.2f%\n",process["Pid"],process["Name"],process["VmSwap"],percent} }' '{}' \;  | awk '{print $(NF-2),$0}' | sort -hr | head | cut -d " " -f2-

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

	#!/bin/bash

	# `gitea dump` doesn't currently back up LFS data as well, only git repos
	# It primarily backs up the SQL DB, and also the config / logs
	# We'll backup like this:
	# * "gitea dump" to backup the DB and config etc
	# * tar / bzip all the repos since they will be skipped
	# * Not rotated because git data is immutable (normally) so has all data
	# * rsync LFS data directly from /volume/docker/gitea/git/lfs
	# * No need for rotation since all files are immutable

	#! /bin/bash

	# NEWLY ADDED BACKUP FUNCTIONALITY IS NOT FULLY TESTED YET, USE WITH CARE, ESPECIALLY DELETION
	# Developed for DSM 6 - 7.0.1. Not tested on other versions.
	# Steps to install
	# Save this script in one of your shares
	# Edit it according to your requirements
	# Backup /usr/syno/share/nginx/ as follows:
	# # cd /usr/syno/share/

	# Backup
	docker exec CONTAINER /usr/bin/mysqldump -u root --password=root DATABASE > backup.sql

	# Restore
	cat backup.sql \| docker exec -i CONTAINER /usr/bin/mysql -u root --password=root DATABASE

	#!/bin/bash

	# Load active ports
	PORTS=`lsof -i \| grep mosh-serv \| cut -f2 -d":"`
	STATUS=`sudo ufw status`

	# Add Rules for new ports
	for PORT in $PORTS; do

	echo $STATUS \| grep "$PORT/udp" > /dev/null
