The kde-unstable entry should be first in the list of repositories i. Make sure you make bug reports if you find any problems. This repository contains broken packages and is used solely by developers during rebuilds of many packages at once. In order to rebuild packages that depend on, for example, a new shared library, the shared library itself must first be built and uploaded to the staging repositories to be made available to other developers.
As soon as all dependent packages are rebuilt, the group of packages is then moved to testing or to the main repositories, whichever is more appropriate. See the announcement of the introduction of the staging repositories for more historical details.
Most of the repository splits are for historical reasons. Originally, when Arch Linux was used by very few users, there was only one repository known as official now core. At the time, official basically contained Judd Vinet's preferred applications. It was designed to contain one of each "type" of program — one DE, one major browser, etc. There were users back then that did not like Judd's selection, so since the Arch Build System is so easy to use, they created packages of their own.
These packages went into a repository called unofficial , and were maintained by developers other than Judd. Eventually, the two repositories were both considered equally supported by the developers, so the names official and unofficial no longer reflected their true purpose.
They were subsequently renamed to current and extra sometime near the release version 0. Shortly after the The repositories are now more or less equal in the eyes of the developers and the community, but core does have some differences. The main distinction is that packages used for Installation CDs and release snapshots are taken only from core. This repository still gives a complete Linux system, though it may not be the Linux system you want.
Some time around 0. Jason Chu set up the "Trusted User Repositories", which were unofficial repositories in which trusted users could place packages they had created.
There was a staging repository where packages could be promoted into the official repositories by one of the Arch Linux developers, but other than this, the developers and trusted users were more or less distinct. This worked for a while, but not when trusted users got bored with their repositories, and not when untrusted users wanted to share their own packages.
For the most part, games will work right out of the box in Arch Linux with possibly better performance than on other distributions due to compile time optimizations. However, some special setups may require a bit of configuration or scripting to make games run as smoothly as desired. Running a multi-screen setup may lead to problems with fullscreen games. In such a case, running a second X server is one possible solution.
Many games grab the keyboard, noticeably preventing you from switching windows also known as alt-tabbing. In some cases like those mentioned above, it may be necessary or desired to run a second X server. The new X server will be akin a remote access login for the ALSA, so your user need to be part of the audio group to be able to hear any sound.
To start a second X server using the free first person shooter game Xonotic as an example you can simply do:. A good reason to provide an alternative xorg. This is undesirable, thus starting a second X with an alternative config where the second screen is disabled is advised.
After making it executable you would be able to do:. For games that require exceptional amount of mouse skill, adjusting the mouse polling rate can help improve accuracy.
To enable, run the following command:. You will also either need to set up Steam to use native runtime, or link its copy of openal. For completeness, also use the following options:. If you are using PulseAudio , you may wish to tweak some default settings to make sure it is running optimally. Pulseaudio is built to be run with realtime priority, being an audio daemon.
However, because of security risks of it locking up the system, it is scheduled as a regular thread by default. To adjust this, first make sure you are in the audio group. PulseAudio on Arch uses speex-float-1 by default to remix channels, which is considered a 'medium-low' quality remixing. If your system can handle the extra load, you may benefit from setting it to one of the following instead:. Matching the buffers can reduce stuttering and increase performance marginally.
See here for more details. If your system is currently configured to properly insert its own cpu frequency scaling driver, the system sets the default governor to Ondemand. This saves power and reduces heat, but has a noticeable impact on performance.
You can instead only have the system downclock when it is idle, by tuning the system governor. To do so, see Cpufrequtils Tuning the ondemand governor. You can switch from "powersave" default to "performance", but the difference is minimal. Cloud gaming has gained a lot of popularity in the last few years, because of low client-side hardware requirements. See Gamepad Gamepad over network for using a gamepad over a network with services that do not normally support this.
See also main article: Improving performance. For Wine programs, see Wine Performance. This can improve game performance. If they do not exist, you have to create them first.
To reduce input latency by disabling synchronization to vblank, add the following:. Most games can benefit if given the correct scheduling policies for the kernel to prioritize the task. These policies should ideally be set per-thread by the application itself.
For programs which do not implement scheduling policies on their own, application known as schedtool , and its associated daemon schedtoold AUR can handle many of these tasks automatically. Highly Configurable Our advanced settings interface lets you tweak every possible option about how the games are run and displayed.
Every setting has a logical default so you can be up and running in no time. Automatic Controller Configuration Common game controllers are automatically configured when plugged in, just like a real console. Ideal for multiplayer games when a friend brings their own controller! You can also configure controllers manually to assign special actions to button combos. Shaders Shaders are efficient graphical filters that can greatly improve the rendering of old games.
They can also be used to replicate the look and feel of old CRT monitors. You can even stack them to create your own effect.
