Swappiness is 60 by default which is fine in most cases. But if you decrease this number, your system will use RAM more and start writing to Swap much later. Swap is an actual disk space and it is much slower than RAM. If you have 8G or more of RAM, you can force your system to use it at maximum.

First, check your swappiness value:

cat /proc/sys/vm/swappiness

Open the /etc/sysctl.conf file with Vim and add vm.swappiness = 10 at the very end.

ssh springm@hermes

sudo su
echo "restic --no-lock -p /root/resticpw -r /backupdisk/restic-repo mount /resticrestore" | at now
cd /resticrestore/hosts/kudell/latest
tar cjf /tmp/kudellroot.tg2 root
tar cjf /tmp/kudelletc.tg2
tar cjf /tmp/kudellspringmssh.tg2 home/springm/.ssh

Auf kudell:

scp springm@hermes:/tmp/kudell*2 /tmp
mv ~springm/.ssh ~springm/.ssh.old
cd /tmp
tar xjf kudellroot.tg2
mv /root /root.old
mv root /

Damit sind die alten ssh-keys wieder intakt.

Ohne diese Maßnahmen funktioniert OpenCL nach Suspend-Resume nicht mehr in darktable.

1.Install ethtool :

sudo apt install ethtool

2.Checking the Interface :

ip a

3.Select the interface you want to use. For Example : enp4s0

4.Turn wake on lan On Temporarily :

sudo ethtool --change enp4s0 wol g

5.Check the WOL status of the interface with the following command :

sudo ethtool enp4s0

6.find the bellow section :

Wake-on: g

Making wake on lan Permanent

7.find ethtool directory :

which ethtool

in my os : /usr/sbin/ethtool

8.Create wol.service in /etc/systemd/system/ with the following content.

[Unit]
Description=Enable Wake On Lan

[Service]
Type=oneshot
ExecStart = /usr/sbin/ethtool --change enp4s0 wol g

[Install]
WantedBy=basic.target

9.Enable The Service :

sudo systemctl daemon-reload
sudo systemctl enable wol.service

Download und installieren entsprechend Anweisungen entsprechend https://signal.org/download/linux/

https://software.opensuse.org/download.html?project=graphics:darktable&package=darktable

Paket von https://software.opensuse.org//download.html?project=graphics%3Adarktable%3Amaster&package=darktable herunterladen und mit dpkg -i installieren

AppImage von https://github.com/darktable-org/darktable/releases/tag/nightly herunterladen.
Starten mit

~/downloads/Darktable-4.7.0+227.g420bc453d7-x86_64.AppImage  --configdir "~/.config/darktable-master" --cachedir "~/.cache/darktable-master"

#!/bin/bash
 
# Usage:
#   dcraw-thumbnailer [size] [source] [destination]
 
# Exit with error on any error
set -e
 
size=$1
source=`echo "$2" | sed 's/file:\/\///'`
destination=$3
 
# Conversion table from EXIF orientation code to degrees (Bash 4 and newer)
declare -A conv=( ["1"]="0" ["3"]="180" ["6"]="90" ["8"]="270" )
 
# Read orientation with exiftool
# Triple -s : output only the value
# -n        : output numerical value, do not convert to human readable form
rotation_code=`exiftool -Orientation -s -s -s -n "$source"`
rotation_deg="${conv[$rotation_code]}"
 
# Extract the thumbnail (usually stored as JPEG) with dcraw, resize, rotate  and convert it.
# The target format will be inferred from the destination file name (usually PNG).
dcraw -c -e -w "$source" | convert -resize ${size}x${size} -rotate "${rotation_deg}" - "$destination"

Damit auch große Raws Thumbnails erhalten:

gsettings set org.gnome.nautilus.preferences thumbnail-limit 500
rm -rf ~/.cache/thumbnails/

bash <(curl --proto '=https' --tlsv1.2 -sSf https://setup.atuin.sh)

Konfiguration für atuin in ~/.config/atuin/config.toml, wichtig hier die Zeile

sync_address = "http://192.168.2.252:8888"

damit der Atuin-Server auf hermes angesprochen wird

For anyone who is using Ubuntu 18 (to give you the same behavior as e.g. on Windows10):

• go to settings > devices > keyboard
• look for the keyboard shortcut for “Switch windows”
• set this to the shortcut Alt+Tab (this will overwrite the old shortcut)

cd /usr/share/applications

Drucker in CUPS einrichten als socket://192.168.2.3:9100 und den Treiber aus dem Build-Verzeichnis (Kyocera FS-1060DN) angeben.

Sound funktioniert über die XONAR SE Soundkarte, Subwoofer läuft nicht am Subwoofer-Ausgang :(
Abhilfe: Subwoofer an den Rear-Port anschließen

mit “tweak”
