|
||||
[System maintenance](https://wiki.archlinux.org/title/System_maintenance) and
|
||||
[troubleshooting](https://wiki.archlinux.org/title/General_troubleshooting) is a
|
||||
reoccurring task to take care of your system and be able to analyze and solve
|
||||
technical issues. In addition, peripherals[^1] sometimes require some tinkering,
|
||||
which supports in the process of learning the details and quirks of your system.
|
||||
For this reason, the sections in this guide focus on the following tasks:
|
||||
|
||||
1. General [#Maintenance](#maintenance) tasks and automation
|
||||
2. Setting up [#Peripherals](#peripherals)
|
||||
1. [#Bluetooth](#bluetooth) controller
|
||||
2. [#Printer and scanner](#printer-and-scanner)
|
||||
3. Additional encrypted [#Storage](#storage)
|
||||
|
||||
## Maintenance
|
||||
|
||||
Ensure the intended system functionality over a period of time: constantly check
|
||||
for errors by using the following command to identify failed systemd services:
|
||||
|
||||
```bash
|
||||
sudo systemctl --failed
|
||||
```
|
||||
|
||||
Use the [Systemd journal](https://wiki.archlinux.org/title/Systemd/Journal) to
|
||||
read logfiles as follows:
|
||||
|
||||
```bash
|
||||
sudo journalctl -p 3 -b
|
||||
```
|
||||
|
||||
[Xorg troubleshooting](https://wiki.archlinux.org/title/Xorg#Troubleshooting)
|
||||
also starts by checking the Systemd journal. Its own logfiles are created in
|
||||
case of any errors inside your user directory. The filename scheme is in the
|
||||
form of `Xorg.n.log` with `n` designating the display number. Search your user
|
||||
directory for such files by using this command:
|
||||
|
||||
```bash
|
||||
grep -e Log -e tty Xorg.0.log
|
||||
```
|
||||
|
||||
Search the [forums](https://bbs.archlinux.org)and ask questions, lookup terms in
|
||||
the [ArchWiki](https://wiki.archlinux.org), and consult a search engine of your
|
||||
choice for debugging errors and interpreting warnings.
|
||||
|
||||
### Backup
|
||||
|
||||
Most important is to maintain a backup[^2] of your system. Filesystem level
|
||||
backup can be done via [rsync](https://wiki.archlinux.org/title/Rsync) and
|
||||
[disk cloning](https://wiki.archlinux.org/title/Disk_Cloning#Using_ddrescue) is
|
||||
a task for the `ddrescue` copmmand. It supports block devices including
|
||||
(optical) disks and SD cards. Install the following packages:
|
||||
|
||||
```bash
|
||||
sudo pacman -Sy ddrescue rsync
|
||||
```
|
||||
|
||||
[Full system backup](https://wiki.archlinux.org/title/Rsync#Full_system_backup)
|
||||
from `$SRC` to `$DST` excluding directory contents of devices and typical mount
|
||||
points is achieved using this command:
|
||||
|
||||
```bash
|
||||
sudo rsync -aAXv --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} $SRC/ $DST/
|
||||
```
|
||||
|
||||
Note that the trailing slash is mandatory for synchronizing the folder contents!
|
||||
You probably want to write a backup script for automation. I like to backup my
|
||||
the filesystems of my machines into a directory named after the hostname on a
|
||||
physical HDD[^3] and clean the filesystem in advance to save space:
|
||||
|
||||
```bash {filename="full-sys-bkp.sh"}
|
||||
#!/bin/bash
|
||||
#
|
||||
# Full system backup using rsync with deletion of non-existent files in $DST
|
||||
# https://wiki.archlinux.org/title/Rsync#Full_system_backup
|
||||
|
||||
SRC=/
|
||||
HST=$(hostnamectl hostname)
|
||||
DST=$(pwd)/$HST
|
||||
|
||||
# Remove old local packages to save space
|
||||
sudo pacman -Scc
|
||||
|
||||
# Clean user data cache
|
||||
rm -rf ~/.cache/*
|
||||
|
||||
# Synchronize
|
||||
sudo rsync \
|
||||
-aAXHv \
|
||||
--delete \
|
||||
--exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} \
|
||||
$SRC \
|
||||
$DST
|
||||
```
|
||||
|
||||
### Logfile limit
|
||||
|
||||
I like to keep Systemd's journal size limit below 200 MB. For this setting, I
|
||||
uncomment and adapt a line in the `/etc/systemd/journald.conf` file to match:
|
||||
|
||||
```{filename="/etc/systemd/journald.conf"}
|
||||
SystemMaxUse=200M
|
||||
```
|
||||
|
||||
Afterwards I need to restart the Journald service:
|
||||
|
||||
```bash
|
||||
sudo systemctl restart systemd-journald.service
|
||||
```
|
||||
|
||||
### Filesystem cleanup
|
||||
|
||||
Files which are not owned by any package can be listed and written to a text
|
||||
file with [lostfiles](https://github.com/graysky2/lostfiles). Additionally, the
|
||||
[rmlint](https://github.com/sahib/rmlint) tool finds (and optionally removes)
|
||||
duplicate files. I install both packages as follows:
|
||||
|
||||
```bash
|
||||
sudo pacman -Sy lostfiles rmlint
|
||||
```
|
||||
|
||||
Lostfiles command is executed via [#sudo](../basic-configuration/#sudo-not-su):
|
||||
|
||||
```bash
|
||||
sudo lostfiles > ~/lostfiles.txt
|
||||
```
|
||||
|
||||
And in addition, The following command finds broken symlinks[^4] and writes them
|
||||
into another `.txt` file for easier post-processing:
|
||||
|
||||
```bash
|
||||
sudo find / -xtype l -print | sudo tee broken_symlinks.txt
|
||||
```
|
||||
|
||||
{{< callout type="warning" >}}
|
||||
If a file is not owned by a package or a symlink is broken does not mean that
|
||||
it is useless! Custom configurations and files copied to system directories
|
||||
are not identified by lostfiles and broken symlinks can have a purpose, see
|
||||
this [Stackexchange post](https://unix.stackexchange.com/questions/151763/is-there-a-downside-to-deleting-all-of-the-broken-symbolic-links-in-a-system)
|
||||
for more information!
|
||||
{{< /callout >}}
|
||||
|
||||
Additionally, I ocasionally create a list of installed packages to investigate
|
||||
potentionally unused or legacy applications by invoking the following command:
|
||||
|
||||
```bash
|
||||
sudo pacman -Qqe > /etc/pkglist.txt
|
||||
```
|
||||
|
||||
### Automation
|
||||
|
||||
You may want to automate some of the aforementioned tasks to happen on a regular
|
||||
basis. The [cronie](https://archlinux.org/packages/?name=cronie) package is a
|
||||
[cron](https://wiki.archlinux.org/title/Cron) functionality provider on a
|
||||
per-user crontab file and can be installed using:
|
||||
|
||||
```bash
|
||||
sudo pacman -Sy cronie
|
||||
```
|
||||
|
||||
{{< callout type="warning" >}}
|
||||
Be careful to not automate the removing of any lost files to prevent missing
|
||||
configurations or other important system-related files!
|
||||
{{< /callout >}}
|
||||
|
||||
I use [Kalu](https://github.com/Thulinma/kalu) as a notifier for package updates
|
||||
available in the official repositories and the AUR. It can be installed with:
|
||||
|
||||
```bash
|
||||
yay kalu
|
||||
```
|
||||
|
||||
I execute `kalu &` to start the notifier. Though I still need to manually run
|
||||
the upgrade process, Kalu can regularly check new packages and offers a 1-click
|
||||
system upgrade.
|
||||
|
||||
## Peripherals
|
||||
|
||||
### Bluetooth
|
||||
|
||||
{{< callout type="info" >}}
|
||||
Before continuing, ensure that the bluetooth device is not blocked by rfkill.
|
||||
I issue the following command and identify the `SOFT` and `HARD` state:
|
||||
|
||||
```bash
|
||||
sudo rfkill
|
||||
```
|
||||
{{< /callout >}}
|
||||
|
||||
There is an increasing amount of peripherals for short-range wireless connection
|
||||
via [bluetooth](https://wiki.archlinux.org/title/Bluetooth). The basic bluetooth
|
||||
capabilities are provided by [bluez](https://archlinux.org/packages/?name=bluez)
|
||||
and [bluez-utils](https://archlinux.org/packages/?name=bluez-utils). These
|
||||
packages are installed as follows:
|
||||
|
||||
```bash
|
||||
sudo pacman -Sy bluez bluez-utils
|
||||
```
|
||||
|
||||
Afterwards I enable and start `bluetooth.service`:
|
||||
|
||||
```bash
|
||||
sudo systemctl enable bluetooth.service
|
||||
sudo systemctl start bluetooth.service
|
||||
```
|
||||
|
||||
Follow [pairing](https://wiki.archlinux.org/title/Bluetooth#Pairing)
|
||||
instructions in the ArchWiki to setup bluetooth devices.
|
||||
|
||||
#### Headset
|
||||
|
||||
Connecting a [headset](https://wiki.archlinux.org/title/Bluetooth_headset) via
|
||||
PipeWire, as configured in [#Sound system](multimedia-web#sound-system),
|
||||
requires the pipewire-pulse package. Proceed with the section Configuration via
|
||||
CLI similar to pairing other bluetooth devices. Or to ease this process, a full-
|
||||
featured management GUI is [Blueman](https://wiki.archlinux.org/title/Blueman).
|
||||
I install the package via:
|
||||
|
||||
```bash
|
||||
sudo pacman -Sy blueman
|
||||
```
|
||||
|
||||
Start the application by invoking `blueman-applet &` and configure bluetooth
|
||||
devices according to the [usage](https://wiki.archlinux.org/title/Blueman#Usage)
|
||||
documentation.
|
||||
|
||||
#### Known bugs
|
||||
|
||||
If the controller is not available or bluetooth seems to crash regularly,
|
||||
disable USB autosuspend to prevent reloading of the `btusb` module. Create a
|
||||
`/etc/modprobe.d/btusb.conf` file with the following content to achieve this
|
||||
behavior:
|
||||
|
||||
``` {filename="/etc/modprobe.d/btusb.conf"}
|
||||
options btusb enable_autosuspend=n
|
||||
```
|
||||
|
||||
### Printer and scanner
|
||||
|
||||
#### CUPS
|
||||
|
||||
Printing is realized with [CUPS](https://wiki.archlinux.org/title/CUPS). After
|
||||
installing the package [cups](https://archlinux.org/packages/?name=cups):
|
||||
|
||||
```bash
|
||||
sudo pacman -Sy cups
|
||||
```
|
||||
|
||||
I start and enable its service:
|
||||
|
||||
```bash
|
||||
sudo systemctl enable cups.service
|
||||
sudo systemctl start cups.service
|
||||
```
|
||||
|
||||
{{< callout type="info" >}}
|
||||
[Printer drivers](https://wiki.archlinux.org/title/CUPS#Printer_drivers) may
|
||||
be required depending on your brand and model.
|
||||
{{< /callout >}}
|
||||
|
||||
Any further configuration of printers can be done graphically via the web
|
||||
interface available at [http://localhost:631](http://localhost:631). One
|
||||
exception is setting the default paper size. However, appending it to the file
|
||||
`/etc/papersize` solves this issue due to CUPS's support lipaper. In Germany the
|
||||
[ISO 216](https://en.wikipedia.org/wiki/ISO_216) (DIN A4) paper size defines the
|
||||
standard. To set `a4` for lipaper I execute the following command:
|
||||
|
||||
```bash
|
||||
sudo echo "a4" | sudo tee -a /etc/papersize
|
||||
```
|
||||
|
||||
#### SANE
|
||||
|
||||
For scanning, I install the [sane](https://archlinux.org/packages/?name=sane)
|
||||
package to use the [SANE](https://wiki.archlinux.org/title/SANE) library. As a
|
||||
graphical frontend [XSane](http://www.xsane.org) provides vast functionality. I
|
||||
install both packages by executing:
|
||||
|
||||
```bash
|
||||
sudo pacman -Sy sane xsane
|
||||
```
|
||||
|
||||
{{< callout type="info" >}}
|
||||
[Scanner drivers](https://wiki.archlinux.org/title/SANE#Scanner_drivers) may
|
||||
be required for your device.
|
||||
{{< /callout >}}
|
||||
|
||||
### Storage
|
||||
|
||||
Additional removable storage such as an USB flash drive[^5] or an external HDD/
|
||||
SSD may be necessary for archiving data at rest. While I tend to use data at
|
||||
rest [encryption](https://wiki.archlinux.org/title/Data-at-rest_encryption) such filesystems can be mounted automatically by using a key stored in and read from
|
||||
the root filesystem for convenience.
|
||||
|
||||
{{% steps %}}
|
||||
|
||||
#### Device identification
|
||||
|
||||
First, I identify the disk device using:
|
||||
|
||||
```bash
|
||||
sudo fdisk -l
|
||||
```
|
||||
|
||||
#### Encryption and opening
|
||||
|
||||
Assuming that your disk is `/dev/sda` the next steps are straightforward and
|
||||
similar to [#Encryption and LVM](../system-preparation#encryption-and-lvm) as
|
||||
documented in the System preparation guide.
|
||||
|
||||
I encrypt and open the block device as follows:
|
||||
|
||||
sudo cryptsetup luksFormat /dev/sda
|
||||
sudo cryptsetup open /dev/sda csd
|
||||
|
||||
{{< callout type="warning" >}}
|
||||
Be careful not to use the disk of your installed system if this disk is at
|
||||
`/dev/sda`! Double check the mount point of your root filesystem by invoking:
|
||||
|
||||
```bash
|
||||
df | grep -w '/'
|
||||
```
|
||||
|
||||
{{< /callout >}}
|
||||
|
||||
#### Filesystem creation
|
||||
|
||||
Other than in the System preparation a single ext4 filesystem inside the LUKS
|
||||
container is sufficient and will be formatted using the command:
|
||||
|
||||
```bash
|
||||
sudo mkfs.ext4 /dev/mapper/csd
|
||||
```
|
||||
|
||||
#### Tuning and labeling
|
||||
|
||||
[Reserved blocks](https://wiki.archlinux.org/title/Ext4#Reserved_blocks) (for
|
||||
root) are not necessary on a removable device. For this reason, I use `tune2fs`
|
||||
and set a label using the `e2label` utility before closing the mapper device:
|
||||
|
||||
```bash
|
||||
sudo tune2fs -m 0 /dev/mapper/csd
|
||||
sudo e2label /dev/mapper/csd csd
|
||||
sudo cryptsetup close csd
|
||||
```
|
||||
|
||||
#### Unlock and mount automation
|
||||
|
||||
I use unlocking with a keyfile to automatically mount the device at boot. A
|
||||
[keyfile](https://wiki.archlinux.org/title/Dm-crypt/Device_encryption#Keyfiles)
|
||||
is created and added to slot 1 of my block device (`/dev/sda` in this example):
|
||||
|
||||
```bash
|
||||
sudo mkdir /etc/cryptsetup-keys.d
|
||||
sudo dd if=/dev/urandom of=/etc/cryptsetup-keys.d/csd.key bs=512 skip=4 count=8
|
||||
sudo cryptsetup luksAddKey /dev/sda /etc/cryptsetup-keys.d/csd.key --key-slot 1
|
||||
```
|
||||
|
||||
Next, I identify and save the UUIDs of `/dev/sda` and `/dev/mapper/csd` in order
|
||||
to append it to the `/etc/crypttab` file using the following commands:
|
||||
|
||||
```bash
|
||||
DevUuid=$(sudo blkid | grep /dev/sda | cut --delimiter=' ' --field=2 | sed 's/[^a-z0-9\\-]//g')
|
||||
echo "csd UUID=$DevUuid /etc/cryptsetup-keys.d/csd.key noauto" | sudo tee -a /etc/crypttab
|
||||
```
|
||||
|
||||
{{< callout type="info" >}}
|
||||
The `noauto` parameter prevents Systemd trying to automatically mounting the
|
||||
encrypted file system at boot leading to a long timeout, if the device is not
|
||||
plugged in. If you are working with non-removable media you must also edit
|
||||
`/etc/fstab` and create mountpoints as necessary.
|
||||
{{< /callout >}}
|
||||
|
||||
Finally, I reload the Systemd daemon using:
|
||||
|
||||
```bash
|
||||
sudo systemctl daemon-reload
|
||||
```
|
||||
|
||||
And I re-plug my storage device to proceed as usual in Thunar [using removable media](https://docs.xfce.org/xfce/thunar/using-removable-media).
|
||||
|
||||
{{% /steps %}}
|
||||
|
||||
Proceed with the configuration of basic [multimedia and web](../multimedia-web)
|
||||
capabilities or go back to the overview and follow instructions for specific
|
||||

|
||||
The [maintainance and peripherals](maintainance-peripherals.md) guide is on how
|
||||
to get an overview on the system state, automating reoccuring tasks, using
|
||||
several utilities and configuring peripherals.
|
||||
The computer is now setup for basic daily tasks and it's time to have some fun.
|
||||
Thus, the next guide deals with setting up a [professional audio](../pro-audio/)
|
||||
environment. If this is not your [use case](../#use-cases), go back to the
|
||||
overview and select another guide.

|
||||
The [Xfce desktop](../xfce-desktop) does not provide any applications for office
|
||||
work. If you need to create office documents containing images and graphs, do
|
||||
spreadsheet[^1] and conduct presentations, there are a lot of packages providing
|
||||
either individual applications or software suites[^2]. I'll cover the most basic
|
||||
needs as follows and refer each application to their proprietary counterpart:
|
||||
|
||||
1. An [#Office suite](#Office-suite) for:
|
||||
1. Word processing
|
||||
2. Spreadsheet
|
||||
3. Presentation
|
||||
2. Viewing and manipulating [#PDF files](#pdf-files)
|
||||
|
||||
## Office suite
|
||||
|
||||
[LibreOffice](https://www.libreoffice.org) is a very powerful office suite and
|
||||
alternative to Microsoft Office. It has improved compatibility to proprietary
|
||||
document formats using file type endings such as `.docx`, `.pptx`, and `.xlsx`,
|
||||
and is regarded as the more actively developed successor to OpenOffice. (See a
|
||||
[comparison](https://www.libreoffice.org/discover/libreoffice-vs-openoffice).)
|
||||
If you need to work with "office files", this is the best option.
|
||||
|
||||
To use the release variant containing the newest features I install the package
|
||||
[libreoffice-fresh](https://archlinux.org/packages/?name=libreoffice-fresh).
|
||||
Additionally, I install a language, spell checking and hyphenation package:
|
||||
|
||||
```bash
|
||||
sudo pacman -Sy libreoffice-fresh
|
||||
sudo pacman -Sy libreoffice-fresh-de hunspell-de hyphen-de
|
||||
```
|
||||
|
||||
There are many [extensions](https://extensions.libreoffice.org) available.
|
||||
I try to find packages in the official repositories or in the AUR to circumvent
|
||||
manual upgrading.
|
||||
|
||||
### Java environment
|
||||
|
||||
Some functions of LibreOffice depend on the Java[^3] programming language. The
|
||||
[OpenJDK](https://wiki.archlinux.org/title/Java#OpenJDK) version is sufficient
|
||||
and provided by [jre-openjdk](https://archlinux.org/packages/?name=jre-openjdk):
|
||||
|
||||
```bash
|
||||
sudo pacman -Sy jre-openjdk
|
||||
```
|
||||
|
||||
### Additional fonts
|
||||
|
||||
Though the Liberation fonts installed in the [#fonts](../xfce-desktop/#fonts)
|
||||
section of the Xfce desktop guide are metric-compatible you might need other
|
||||
[font families](https://wiki.archlinux.org/title/Fonts#Families) to avoid font
|
||||
replacement and metric problems while collaborating. I install the packages
|
||||
[ttf-ms-fonts](https://aur.archlinux.org/packages/ttf-ms-fonts/) and
|
||||
[ttf-vista-fonts](https://aur.archlinux.org/packages/ttf-vista-fonts/) from the
|
||||
AUR as follows:
|
||||
|
||||
```bash
|
||||
yay ttf-ms-fonts ttf-vista-fonts
|
||||
```
|
||||
|
||||
{{< callout type="info" >}}
|
||||
[Current packages](https://wiki.archlinux.org/title/Microsoft_fonts#Current_packages)
|
||||
for Microsoft fonts require access to the installation media and do not
|
||||
provide the fonts itself.
|
||||
{{< /callout >}}
|
||||
|
||||
Other recommended font packages are ttf-bitstream-vera, ttf-croscore,
|
||||
gnu-free-fonts, noto-fonts, ttf-roboto and ttf-ubuntu-font-family. I install
|
||||
these using the following command:
|
||||
|
||||
```bash
|
||||
sudo pacman -Sy ttf-bitstream-vera ttf-croscore gnu-free-fonts noto-fonts ttf-roboto ttf-ubuntu-font-family
|
||||
```
|
||||
|
||||
If you need fonts optimized for emojis and symbols, math or other operating
|
||||
system fonts search the ArchWiki.
|
||||
|
||||
## PDF files
|
||||
|
||||
A [comparison](https://wiki.archlinux.org/title/PDF,_PS_and_DjVu#Comparison) of
|
||||
PDF applications reveals that [Xreader](https://github.com/linuxmint/xreader/)
|
||||
seems to be a lightweight but also full-featured PDF viewer powered by the
|
||||
[Poppler](https://poppler.freedesktop.org) rendering library. It is capable of
|
||||
annotation, forms, and non-rectangle selection of text, and can be installed
|
||||
using the following command:
|
||||
|
||||
```bash
|
||||
sudo pacman -Sy xreader
|
||||
```
|
||||
|
||||
### Signatures and handwrriting
|
||||
|
||||
If you need to add a signature or image to pages in a PDF or want to use
|
||||
handwritten notes also install the [Xournal++](https://xournalpp.github.io)
|
||||
application:
|
||||
|
||||
```bash
|
||||
sudo pacman -Sy xournalpp
|
||||
```
|
||||
|
||||
### Encrypt PDF files
|
||||
|
||||
In order to encrypt PDF files I use [qpdf](https://qpdf.sourceforge.io) and
|
||||
visual extraction, split, merge and reorganization of pages can be done in the
|
||||
[PDF Mix Tool](https://www.scarpetta.eu/pdfmixtool). I Install these apps using
|
||||
the following command:
|
||||
|
||||
```bash
|
||||
sudo pacman -Sy qpdf pdfmixtool
|
||||
```
|
||||
|
||||
To actually encrypt a PDF file the syntax is:
|
||||
|
||||
```bash
|
||||
qpdf --encrypt $USERPASSWORD $OWNERPASSWORD $KEYLENGTH -- file.pdf encrypted.pdf
|
||||
```
|
||||
|
||||
I set an `$USERPASSWORD`, `$OWNERPASSWORD`, and `$KEYLENGTH` variable in advance
|
||||
and set the key length to the maximum of 256 bits (`KEYLENGTH=256`).

## File renaming
|
||||
|
||||
Working with files containing special characters is cumbersome (especially in
|
||||
the terminal) and the [FAT](https://wiki.archlinux.org/title/FAT) filesystem,
|
||||
for example, does not allow them. The [detox](https://detox.sourceforge.net)
|
||||
utility removes umlauts[^1], spaces and special characters, such as `?`, and
|
||||
replaces them with an underscore (`_`) (or in case of `&` with an `_and_`). I
|
||||
install the [detox](https://archlinux.org/packages/?name=detox) package:
|
||||
|
||||
```bash
|
||||
sudo pacman -Sy detox
|
||||
```
|
||||
|
||||
And to rename files with it I navigate to the directory of interest and run:
|
||||
|
||||
```bash
|
||||
detox -rv
|
||||
```
|
||||
|
||||
## Interoperability
|
||||
|
||||
For some interoperability[^2] during advanced tasks such as labeling partitions
|
||||
of Windows filesystems (FAT, exFAT and NTFS[^3]) or dealing with control letters
|
||||
(DOS or Windows carriage returns[^4]), I install the following packages:
|
||||
|
||||
```bash
|
||||
sudo pacman -Sy dos2unix dosfstools exfatprogs ntfs-3g
|
||||
```
|
||||
|
||||
Consider to install [e2fsprogs](https://archlinux.org/packages/?name=e2fsprogs)
|
||||
for [ext4](https://wiki.archlinux.org/title/Ext4) partition tasks if this is not
|
||||
installed by dependencies, already.
|
||||
|
||||
## Password manager
|
||||
|
||||
I use a local password manager[^5] to generate random secrets and store secret
|
||||
information for convenience and security. My favorite application is the cross-
|
||||
plattform application [KeepassXC](https://wiki.archlinux.org/title/KeePass). It
|
||||
uses encrypted password database files and can be installed with the command:
|
||||
|
||||
```bash
|
||||
sudo pacman -Sy keepassxc
|
||||
```
|
||||
|
||||
For browser integration, (see [#Web browser](multimedia-web#web-browser) section
|
||||
of the Multimedia and web guide) you need to install the add-on [KeepassXC-Browser](https://addons.mozilla.org/en-US/firefox/addon/keepassxc-browser/).
|
||||
Click the *Add-ons and themes* option in LibreWolf's menu, or open a new tab and
|
||||
navigating to the page `about:addons`, or the use the `<Ctrl>+<Shift>+<a>`
|
||||
keystroke.
|
||||
|
||||
In KeepassXC go to *Tools* > *Settings* > *Browser Integration* > *Advanced* >
|
||||
*Config Location:* and add `~/.librewolf/native-messaging-hosts` to finish the
|
||||
integration setup.
|
||||
|
||||
## Scientific calculator
|
||||
|
||||
[SpeedCrunch](http://speedcrunch.org) is feature-rich a scientific calculator
|
||||
with a keyboard-driven interface documented in the page [First Steps](https://heldercorreia.bitbucket.io/speedcrunch/userguide/first_steps.html).
|
||||
I install the [speedcrunch](https://archlinux.org/packages/?name=speedcrunch)
|
||||
package as follows:
|
||||
|
||||
```bash
|
||||
sudo pacman -Sy speedcrunch
|
||||
```
|
||||
|
||||
Proceed with installing and configuring [Office tools](../office-tools) in just
|
||||
another guide or go back to the overview and follow instructions for specific
|
||||
[use cases](../#use-cases).
