Αυτό το έγγραφο είναι μία ένας κατάλογος δημοφιλών άρθρων και σημαντικών πληροφοριών για την βελτίωση και προσθήκη λειτουργιών προς εγκατάσταση στο σύστημα Arch. Είναι δεδομένο ότι οι αναγνώστες έχουν διαβάσει και ακολουθήσει τον οδηγό εγκατάστασης Installation guide για να αποκτήσουν μία βασική εγκατάσταση του Arch Linux. Έχοντας διαβάσει και καταλάβει τις έννοιες που εξηγούνται στο #System administration και #Διαχείριση πακέτων απαιτείται για να ακολουθήσουν τις υπόλοιπες ενότητες αυτής της σελίδας και άλλα άρθρα στο wiki.

## System administration

Αυτή η ενότητα ασχολείται με διοικητικά καθήκοντα και διαχείριση συστήματος. Δείτε Core utilities και Category:System administration για περισσότερα.

### Χρήστες και ομάδες

A new installation leaves you with only the superuser account, better known as "root". Logging in as root for prolonged periods of time, possibly even exposing it via SSH on a server, is insecure. Instead, you should create and use unprivileged user account(s) for most tasks, only using the root account for system administration. See Users and groups#User management for details.

Users and groups are a mechanism for access control; administrators may fine-tune group membership and ownership to grant or deny users and services access to system resources. Read the Users and groups article for details and potential security risks.

### Ασφάλεια

Διαβάστε την ενότητα Security για συστάσεις και ενδεδειγμένες πρακτικές στην βελτιστοποίηση ασφαλείας του συστήματος σας.

Για μία λίστα εφαρμογών που επιτρέπουν την εκτέλεση εντολών ή έναρξη ενός διαδραστικού κελύφους ως άλλος χρήστης (π.χ root), δείτε List of applications/Security#Privilege elevation.

### Service management

Arch Linux uses systemd as the init process, which is a system and service manager for Linux. For maintaining your Arch Linux installation, it is a good idea to learn the basics about it.

Interaction with systemd is done through the systemctl command. See systemd#Basic systemctl usage for more information.

A logging system is also provided, with the command journalctl. See journal for more information.

### Συντήρηση συστήματος

Το Arch διαθέτει ένα σύστημα κυλιόμενων εκδόσεων με μια μεγάλη κινητικότητα πακέτων . Γι'αυτό οι χρήστες θα πρέπει να αφιερώσουν χρόνο για να κάνουν system maintenance.

## Διαχείριση πακέτων

This section contains helpful information related to package management. See FAQ#Package management and Category:Package management for more.

Note: It is imperative to keep up to date with changes in Arch Linux that require manual intervention before upgrading your system. Subscribe to the arch-announce mailing list or the recent news RSS feed. Alternatively, check the front page Arch news every time before you update.

### Mirrors

Visit the Mirrors article for steps on taking full advantage of using the fastest and most up to date mirrors of the official repositories. As explained in the article, a particularly good advice is to routinely check the Mirror Status page for a list of mirrors that have been recently synced. This can be automated with Reflector.

### Arch Build System

Ports is a system initially used by BSD distributions consisting of build scripts that reside in a directory tree on the local system. Simply put, each port contains a script within a directory intuitively named after the installable third-party application.

The Arch build system offers the same functionality by providing build scripts called PKGBUILDs, which are populated with information for a given piece of software: integrity hashes, project URL, version, license and build instructions. These PKGBUILDs are parsed by makepkg, the actual program that generates packages that are cleanly manageable by pacman.

Every package in the repositories along with those present in the AUR are subject to recompilation with makepkg.

### Arch User Repository

While the Arch Build System allows the ability of building software available in the official repositories, the Arch User Repository (AUR) is the equivalent for user submitted packages. It is an unsupported repository of build scripts accessible through the web interface or through the Aurweb RPC interface.

## Booting

This section contains information pertaining to the boot process. An overview of the Arch boot process can be found at Arch boot process. See Category:Boot process for more.

### Αυτόματη αναγνώριση hardware

Hardware should be auto-detected by udev during the boot process by default. A potential improvement in boot time can be achieved by disabling module auto-loading and specifying required modules manually, as described in Kernel modules. Additionally, Xorg should be able to auto-detect required drivers using `udev`, but users have the option to configure the X server manually too.

### Μικροκώδικας

Processors may have faulty behaviour, which the kernel can correct by updating the microcode on startup. See Microcode for details.

### Διατήρηση μηνυμάτων εκκίνησης

Once the login prompt appears, the messages from boot are cleared, leaving users unable to gather feedback from them. Disable clearing of boot messages to overcome this limitation.

### Num Lock activation

Num Lock is a toggle key found in most keyboards. For activating Num Lock's number key-assignment during startup, see Activating numlock on bootup.

## Γραφική διεπαφή χρήστη

This section provides orientation for users wishing to run graphical applications on their system. See Category:Graphical user interfaces for additional resources.

### Display server

Xorg is the public, open-source implementation of the X Window System (commonly X11, or X). It is required for running applications with graphical user interfaces (GUIs), and the majority of users will want to install it.

Wayland is a newer, alternative display server protocol with several compositors to choose from.

### Display drivers

The default modesetting display driver will work with most video cards, but performance may be improved and additional features harnessed by installing the appropriate driver for AMD or NVIDIA products.

### Desktop environments

Although the display server provides the basic framework for building a graphical environment, additional components may be considered necessary for a complete user experience. Desktop environments such as KDE, GNOME, Xfce, Cinnamon, LXDE, bundle together a wide range of well-integrated applications, such as a window manager or compositor, panel/taskbar, file manager, terminal emulator, text editor, icons, and other utilities. Users with less experience may wish to install a desktop environment for a more familiar environment. See Category:Desktop environments for additional resources.

### Window managers or compositors

A full-fledged desktop environment provides a complete and consistent graphical user interface, but tends to consume a good amount of system resources. Users seeking to maximize performance or otherwise simplify their environment may opt to install a window manager or compositor alone and hand-pick desired extras. Using Xorg, most desktop environments allow use of an alternative window manager as well. Dynamic, stacking, and tiling window managers differ in their handling of window placement.

### Display manager

Most desktop environments include a display manager for automatically starting the graphical environment and managing user logins. Users without a desktop environment can install one separately. Alternatively you may start X at login as a simple alternative to a display manager.

### User directories

Well-known user directories like Downloads or Music are created by the `xdg-user-dirs-update.service` user service, that is provided by xdg-user-dirs and enabled by default upon install. If your desktop environment or window manager does not pull in the package, you can install it and run `xdg-user-dirs-update` manually as per XDG user directories#Creating default directories.

## Power management

This section may be of use to laptop owners or users otherwise seeking power management controls. See Category:Power management for more.

See Power management for more general overview.

### ACPI events

Users can configure how the system reacts to ACPI events such as pressing the power button or closing a laptop's lid. For the recommended method using systemd, see Power management#ACPI events. For the old method, see acpid.

### CPU frequency scaling

Modern processors can decrease their frequency and voltage to reduce heat and power consumption. Less heat leads to more quiet system and prolongs the life of hardware. See CPU frequency scaling for details.

### Laptops

For articles related to portable computing along with model-specific installation guides, please see Category:Laptops. For a general overview of laptop-related articles and recommendations, see Laptop.

### Suspend and hibernate

See the main article: Power management/Suspend and hibernate.

## Πολυμέσα

Category:Multimedia includes additional resources.

### Σύστημα ήχου

ALSA is a kernel sound system that should work out the box (it just needs to be unmuted). Sound servers such as PipeWire and PulseAudio can offer additional features and support more complex audio configuration.

See Professional audio for advanced audio requirements.

## Δίκτυο

This section is confined to small networking procedures. See Network configuration for a full configuration guide and Category:Networking for related articles.

### Ασφάλεια DNS

For better security while browsing the web, paying online, connecting to SSH services and similar tasks consider using DNSSEC-enabled DNS resolver that can validate signed DNS records, and an encrypted protocol such as DNS over TLS, DNS over HTTPS or DNSCrypt. See Domain name resolution for details.

### Setting up a firewall

A firewall can provide an extra layer of protection on top of the Linux networking stack. While the stock Arch kernel is capable of using Netfilter's iptables and nftables, neither are enabled by default. It is highly recommended to set up some form of firewall. See Category:Firewalls for available guides.

### Network shares

To share files among the machines in a network, follow the NFS or the SSHFS article.

Use Samba to join a Windows network. To configure the machine to use Active Directory for authentication, read Active Directory integration.

See also Category:Network sharing.

## Input devices

This section contains popular input device configuration tips. See Category:Input devices for more.

### Keyboard layouts

Non-English or otherwise non-standard keyboards may not function as expected by default. The necessary steps to configure the keymap are different for virtual console and Xorg, they are described in Keyboard configuration in console and Keyboard configuration in Xorg respectively.

### Mouse buttons

Owners of advanced or unusual mice may find that not all mouse buttons are recognized by default, or may wish to assign different actions for extra buttons. Instructions can be found in Mouse buttons.

### Laptop touchpads

Many laptops use Synaptics or ALPS "touchpad" pointing devices. For these, and several other touchpad models, you can use either the Synaptics input driver or libinput; see Touchpad Synaptics and libinput for installation and configuration details.

### TrackPoints

See the TrackPoint article to configure your TrackPoint device.

## Βελτιστοποίηση

This section aims to summarize tweaks, tools and available options useful to improve system and application performance.

### Benchmarking

Benchmarking is the act of measuring performance and comparing the results to another system's results or a widely accepted standard through a unified procedure.

### Improving performance

The Improving performance article gathers information and is a basic rundown about gaining performance in Arch Linux.

### Solid state drives

The Solid state drive article covers many aspects of solid state drives, including configuring them to maximize their lifetimes, e.g. with TRIM.

## Υπηρεσίες συστήματος

Αυτή η ενότητα σχετίζεται με τους daemons.

### File index and search

Most distributions have a locate command available to be able to quickly search files. Arch Linux provides several alternatives, see locate for details.

Desktop search engines provide a similar service, while better integrated into desktop environments.

### Τοπική παράδοση mail

A default setup does not provide a way to synchronize mail. A list of mail delivery agents is available in the Mail server article.

### Εκτύπωση

CUPS is a standards-based, open source printing system developed by OpenPrinting for Linux. See Category:Printers for printer-specific articles.

## Εμφάνιση

This section contains frequently-sought "eye candy" tweaks for an aesthetically pleasing Arch experience. See Category:Eye candy for more.

### Γραμματοσειρές

You may wish to install a set of TrueType fonts, as only unscalable bitmap fonts are included in a basic Arch system. There are several general-purpose font families providing large Unicode coverage and even metric compatibility with fonts from other operating systems.

A plethora of information on the subject can be found in the Fonts and Font configuration articles.

If spending a significant amount of time working from the virtual console (i.e. outside an X server), users may wish to change the console font to improve readability; see Linux console#Fonts.

### GTK and Qt themes

A big part of the applications with a graphical interface for Linux systems are based on the GTK or the Qt toolkits. See those articles and Uniform look for Qt and GTK applications for ideas to improve the appearance of your installed programs and adapt it to your liking.

## Console improvements

This section applies to small modifications that improve console programs' practicality. See Category:Command-line shells for more.

### Tab-completion enhancements

It is recommended to properly set up extended tab completion right away, as instructed in the article of your chosen shell.

### Aliases

Aliasing a command, or a group thereof, is a way of saving time when using the console. This is especially helpful for repetitive tasks that do not need significant alteration to their parameters between executions. Common time-saving aliases can be found in Bash#Aliases, which are easily portable to zsh as well.

### Alternative shells

Bash is the shell installed by default in an Arch system. The live installation media, however, uses zsh with the grml-zsh-config addon package. See Command-line shell#List of shells for more alternatives.

### Bash additions

A list of miscellaneous Bash settings, history search and Readline macros is available in Bash#Tips and tricks.

### Colored output

This section is covered in Color output in console.

### Compressed files

Compressed files, or archives, are frequently encountered on a GNU/Linux system. Tar is one of the most commonly used archiving tools, and users should be familiar with its syntax (Arch Linux packages, for example, are simply zstd compressed tarballs). See Archiving and compression.

### Console prompt

The console prompt (`PS1`) can be customized to a great extent. See Bash/Prompt customization or Zsh#Prompts if using Bash or Zsh, respectively.

### Emacs shell

Emacs is known for featuring options beyond the duties of regular text editing, one of these being a full shell replacement. Consult Emacs#Colored output issues for a fix regarding garbled characters that may result from enabling colored output.

### Mouse support

Using a mouse with the console for copy-paste operations can be preferred over GNU Screen's traditional copy mode. Refer to General purpose mouse for comprehensive directions. Note that you can already do this in terminal emulators with the clipboard.

### Session management

Using terminal multiplexers like tmux or GNU Screen, programs may be run under sessions composed of tabs and panes that can be detached at will, so when the user either kills the terminal emulator, terminates X, or logs off, the programs associated with the session will continue to run in the background as long as the terminal multiplexer server is active. Interacting with the programs requires reattaching to the session.

### POSIX shell utilities

This article or section is a candidate for moving to Core utilities.

Notes: The topic is still better suited for the dedicated page. (Discuss in Talk:General recommendations (Ελληνικά))

Many common packages already install most popular POSIX utilities as dependencies, but the posix metapackage can be installed to ensure all of them being always present.

Beside mandatory utilities, there are also metapackages for some of the optional categories:

- posix-c-development
- posix-software-development
- posix-user-portability
- posix-xsi

Note: Not all optional utilities from given category are necessarily present in corresponding metapackage.
