====== Kudell auf Debian ======


===== Installierte Pakete =====

==== /etc/apt/sources.list ====

==== Installation ====

    vim gimp ffmpeg default-jdk git wget nano vim \

  sudo apt purge fonts-noto-color-emoji

==== user-account in sudoers ====
Hinzufügen des Benutzernamens in die Zeile ''sudo'' der Datei ''/etc/group''

==== Swappiness senken ====
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.

==== Einschub: Verbindung zu hermes und den backups herstellen ====
  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 etc
  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.

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

</file>

anlegen und 

  systemctl enable nvidia-suspend.service
ausführen.

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

===== Einstellungen =====
==== Alt-Tab Verhalten ändern ====
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)

==== Zusätzliche emacs-Desktop-Einträge verhindern ====
  cd /usr/share/applications
  sudo chmod 600 emacsclient.desktop emacs-term.desktop
  
==== Mac-Theme ====

===== Drucken auf Kyocera 1061 =====
Wird nicht vom Standard-Debian unterstützt
<file bash>
cd ~/projekte
mkdir kyocera
cd kyocera
git clone https://github.com/Fe-Ti/rastertokpsl-re/
cd rastertokpsl-re/
sudo apt install libcupsimage2-dev libcups2-dev cmake
cmake -B_build -H.
cmake --build _build/
sudo ./install.sh
</file>

Drucker in CUPS einrichten als %%socket://192.168.2.3:9100%% und den neu gebauten Treiber ''Kyocera FS-1060DN-KPDSL angeben.

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