    Post-Install Configuration (Manjaro MATE)

    Below is a collection of commands and snippets I have put together over the years. Pick out the parts you find useful, and create your own one-click system configuration shell script.

    Encrypted Home partition

    If you have a default Manjaro installation with full disk encryption, your Home is not separated from the rest of the system. Here is how to add a separate Home partition - make sure your encryption password matches the one you used during installation.

    PARTITION="/dev/sda2"
sudo cryptsetup luksFormat --type luks2 $PARTITION
sudo cryptsetup open /dev/$PARTITION Home
sudo mkfs.ext4 /dev/mapper/Home
sudo mkdir /mnt/home
sudo mount /dev/mapper/Home /mnt/home
sudo rsync --recursive --links --hard-links --perms --executability --acls --xattrs --owner --group --times --whole-file --progress --ignore-times "/home/$USER" /mnt/home
echo "Home UUID=$(lsblk --nodeps --noheadings -o UUID $PARTITION) /crypto_keyfile.bin luks" | sudo tee -a /etc/crypttab
echo "/dev/mapper/Home /home ext4 defaults,noatime 0 2" | sudo tee -a /etc/fstab
sudo cryptsetup luksAddKey $PARTITION /crypto_keyfile.bin
sudo umount /mnt/home
sudo rmdir /mnt/home

    Swap file

    This creates a Swap file the same size as your RAM.

    sudo dd if=/dev/zero of=/swapfile bs=1M count=`grep MemTotal /proc/meminfo | awk '{print $2 / 1024}' OFMT="%0.0f"` status=progress
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
echo "/swapfile none swap defaults 0 0" | sudo tee -a /etc/fstab

    Temp folder on disk

    This mounts /tmp on disk rather than in RAM.

    sudo systemctl mask tmp.mount

cat << EOL | sudo tee "/etc/tmpfiles.d/tmp.conf"
# see tmpfiles.d(5)
# always enable /tmp folder cleaning
D! /tmp 1777 root root 0

# remove files in /var/tmp older than 10 days
D /var/tmp 1777 root root 10d

# namespace mountpoints (PrivateTmp=yes) are excluded from removal
x /tmp/systemd-private-*
x /var/tmp/systemd-private-*
X /tmp/systemd-private-*/tmp
X /var/tmp/systemd-private-*/tmp
EOL

    Firefox in RAM

    This moves your firefox profile to RAM.

    sudo pamac install profile-sync-daemon
firefox about:config

# Set browser.cache.disk.parent_directory to /run/user/1000/firefox

systemctl --user enable psd.service

    Sudo timeout

    This disables the timeout for sudo.

    EDITOR=nano sudo visudo

# Append this line:
Defaults timestamp_timeout=-1

    Pulse Audio resampling

    This will get you bit-perfect output.

    cp -r /etc/pulse $HOME/.config
sed -i "s/^; avoid-resampling.*/avoid-resampling = true/" $HOME/.config/pulse/daemon.conf
sed -i "s/^; default-sample-format.*/default-sample-format = s24le/" $HOME/.config/pulse/daemon.conf

    Hard disk power management

    Some laptop hard drives may produce frequent clicking noises due to the aggressive power management setting. 255 should disable APM completely. Change sda to match your device.

    echo "ACTION==\"add\", SUBSYSTEM==\"block\", KERNEL==\"sda\", RUN+=\"/usr/bin/hdparm -B 255 /dev/sda\"" | sudo tee -a /etc/udev/rules.d/69-hdparm.rules

    Software settings

    Here are some settings for sources and updates.

    sudo sed -i "s@RefreshPeriod = 6@RefreshPeriod = 24@" /etc/pamac.conf
sudo sed -i "s@#RemoveUnrequiredDeps@RemoveUnrequiredDeps@" /etc/pamac.conf
sudo sed -i "s@#EnableAUR@EnableAUR@" /etc/pamac.conf
sudo sed -i "s@#CheckAURUpdates@CheckAURUpdates@" /etc/pamac.conf
#sudo sed -i "s@#DownloadUpdates@DownloadUpdates@" /etc/pamac.conf
sudo sed -i "s@#CheckAURVCSUpdates@CheckAURVCSUpdates@" /etc/pamac.conf

    Upgrade the whole system

    This will pull all available updates, so be patient.

    pamac upgrade --aur

    Install Additional Software

    This is what I usually add to a system, change the list to suit your needs.

    # Tools for building things from source
sudo pamac install base-devel

# Ayatana indicators
pamac build ayatana-indicator-application ayatana-indicator-power ayatana-indicator-session ayatana-indicator-messages ayatana-indicator-datetime ayatana-indicator-sound ayatana-indicator-printers ayatana-indicator-display mate-indicator-applet matekbd-keyboard-display

# Ubuntu look
pamac build ambiant

# Font for displaying emojis
sudo pamac install noto-fonts-emoji

# Applications
pamac build caja-rename ayatana-webmail my-weather-indicator-git telegram-desktop-bin
sudo pamac install pamac-tray-icon-plasma evolution vlc aisleriot trash-cli inkscape gimp strawberry mkvtoolnix-gui

    Automagically delete old trash

    This checks the trash on reboot and removes anything older than 30 days. 

    (crontab -l 2>/dev/null; echo "@reboot /usr/bin/trash-empty 30") | crontab -

    Login screen

    Some fixes and settings.

    sudo sed -i "s/^hidden-shells=\/bin\/false \/usr\/bin\/nologin$/hidden-shells=\/bin\/false \/usr\/bin\/nologin \/sbin\/nologin/" /etc/lightdm/users.conf
echo "activate-numlock=true" | sudo tee -a /etc/lightdm/slick-greeter.conf

    Handler for mailto: links

    If you're using a webmail host other than GMail, you may use this: 

    cat << EOL | sudo tee "/usr/share/applications/mailto.desktop"
[Desktop Entry]
Name=Mailto
Type=Application
Exec=firefox https://mail.example.com/YOUR_SEND_MAIL_URL=%u
Categories=Email;
MimeType=x-scheme-handler/mailto;
OnlyShowIn=None
EOL

xdg-settings set default-url-scheme-handler mailto mailto.desktop
