|Linux||September 17, 1991|
Linux is the open-source Unix-like operating system based around the kernel of the same name created by Linus Torvalds and released in September 17, 1991. As the kernel itself lacks many user-level tools, it is often paired with free and open-source software (FOSS) provided by the GNU Project as well as other popular user-level applications, and packaged as a "distribution" ("distro" for short). As a result of its reliance on tools provided by the GNU Project, the operating system consisting of the kernel and bundled user-level tools is sometimes controversially referred to as GNU/Linux as well. The operating system sees ongoing development and due to its free and open-source nature is often used as the base on which other services or platforms are built on, such as Stadia and Steam Deck.
Users wanting to find a distribution of Linux usually end up following a few general guidelines:
- The strength and weakness of Linux is its freedom of user choice.
- There are no best distros; it all depends on the user's need. Users commonly switch between distros ("distro hopping") until settling on one.
- Always refer to the documentation of the chosen distro in case there is a problem. It's advisable to check the ArchWiki regardless of the distro as it is broadly and succinctly written. In addition, reaching out to the distro's community for support is always an option.
- Use virtual machines to test Linux distributions without replacing the existing operating system on the physical machine.
- Wide variety of distributions (distros) available, allowing unparalleled user choice and customizability.
- Some native Linux games may perform better or worse when compared to other operating systems.
- Many Windows games can be played on Linux using Proton or Wine.
- DistroWatch - page dedicated to Linux distributions
- Linux Journey - a beginner-friendly page about learning Linux in general
- ProtonDB - crowdsourced database of Proton games compatibility
- Phoronix - website dedicated to hardware and benchmarking in Linux
- OpenBenchmarking and FlightlessMango - lists of user-made benchmarks in Linux
- ArchWiki and Gentoo Wiki - wikis intended for their respective distro but is useful for others as well
- Gaming On Linux - a large community dedicated for gaming on Linux
- /r/linux_gaming - Linux gaming subreddit
There are two types of release models for Linux distros.
- Offers stable packages.
- Most distros are beginner-friendly.
- Very little maintenance.
- Package versions are usually tied to distro version, so the OS needs to be updated to get the latest packages.
- Stable packages typically don't have the newest features. This is especially important in the case of GPU drivers.
This issue is alleviated by the fact that the vast majority of user-facing applications are now available as a Flatpak, Snap or and AppImage which allow you to run the latest version of the application regardless of what exact version of underlying OS you have.
- Manual intervention is required to add user-made repositories in some distros.
- Updating a distro to the latest version doesn't normally require a fresh install, but can take up to several hours.
- Many Debian-based distros offer "backports" and/or "testing" modes that provide newer versions of some packages than what the stable version does.
|Distribution||Based on||Desktop(s) [fr note 1]||Release cycle||Supported by[fr note 2]||Description|
|Ubuntu and Ubuntu flavours||Debian||GNOME, KDE Plasma, LXQt, Budgie, MATE, Xfce, UKUI||6 months, 2 years for LTS||Steam, GOG, many commercial developers||The most popular distribution. Ubuntu LTS (Long Term Support) is officially supported by Steam. Ubuntu non-LTS is updated more often and contains newer packages and functionality. Ubuntu flavours offer different desktop environments with the same compatibility of Ubuntu.|
|Pop!_OS||Ubuntu||GNOME||6 months||same as Ubuntu[fr note 3]||An Ubuntu-based distro created and maintained by System76 which utilizes its own repository. Unlike Ubuntu, it includes much more recent drivers for graphics cards, the installer ships with Nvidia supporta, and it's generally more recommended for beginners.|
|Linux Mint||Ubuntu LTS||Cinnamon, MATE, XFCE||Up to 2 years||same as Ubuntu[fr note 3]||The most popular beginner-friendly Linux distribution. LMDE 2 Edition is based on Debian. Packages may be much older compared to Ubuntu LTS releases. The main advantage of Linux Mint is the built-in kernel upgrader.|
|KDE Neon||Ubuntu LTS||KDE Plasma||Up to a year||same as Ubuntu[fr note 3]||A distro created by the KDE community. Compared to Kubuntu (A KDE Plasma-flavoured Ubuntu), it provides the latest version of the KDE Plasma desktop environment, while simultaneously being able to use packages from Ubuntu LTS.|
|Fedora and Fedora Spins||Independent||GNOME, KDE Plasma, XFCE, MATE, Cinnamon, LXDE, LXQT, SUGAR||6 months||Fedora is a very stable, independent distribution sponsored by Red Hat Enterprise. GNOME is its default desktop environment, but Fedora Spins offer many alternatives. It is as user-friendly as Ubuntu, but tends to be more willing to move to new technologies. Spins offer different desktop environments, but when it comes to compatibility, they are the same as Fedora.|
|openSUSE Leap||Independent||GNOME, KDE Plasma, XFCE||1 year for each new release||Leap uses source from SUSE Linux Enterprise (SLE), which gives it a great level of stability. openSUSE has YaST, which is a user-friendly GUI to install packages, manage the system, and install Nvidia proprietary drivers in a simple way.|
|SteamOS||Arch Linux(starting with version 3.0) Debian(old versions)||KDE Plasma||Varies||Steam||Linux distribution made by Valve Corporation specifically for the Steam Machine or couch gaming. It currently provides the latest stable Linux kernel along with newer GPU drivers and an option to act as a desktop system. It may be behind in terms of packages updates.|
- Default options are marked in bold
- look at Official Support TODO: add it
- Support is not official, but the distros are similar enough that everything which works for Ubuntu will work in Pop!_OS.
- Provides the latest version of packages once as soon as they're released by the upstream developers.
- No distro upgrade procedure is required, as most distros have only one version.
- A package update may cause stability issues, as extensive testing is usually limited.
- No currently-listed rolling release distribution has official support from any digital distribution store, due to the distros' reliance on
.rpmbinaries instead of
- Some distros offer a semi-rolling release, meaning that packages will be tested before releases.
|Distribution||Based On||Desktop(s)[rr note 1]||Description|
|Arch Linux||Independent||GNOME, KDE Plasma, XFCE, MATE, Cinnamon, LXDE, LXQT, SUGAR, Deepin, Budgie, UKUI||Arch Linux is a distribution designed for advanced users looking to customize every aspect of their system, building from the ground up rather than the top down. There is a huge number of packages available through the AUR (Arch User Repository). Arch Linux does not have a graphical installer and requires research on the user's part to properly install.|
|Manjaro||Arch Linux||GNOME, KDE Plasma, Xfce||Manjaro is based on Arch Linux and offers a user-friendly experience out of the box. By default, it comes with Nvidia's proprietary drivers, which makes it straightforward to install. It uses the Pamac app to install native, AUR, Flatpak, and Snap packages in a simple way.|
|openSUSE Tumbleweed||Independent||GNOME, KDE Plasma, XFCE||A rolling version of openSUSE which uses automated testing to provide more stability than many other rolling releases. When used with BTRFS on a root partition, snapshots are taken before and after updates, allowing easy restores if there is an update breakage.|
|Solus||Independent||Budgie, GNOME, MATE, KDE Plasma||Despite following the rolling release model, it provides stable packages and features great hardware compatibility with any GPU. It includes a special tool called Linux Steam Integration (LSI) which allows users to easily customize Steam, ranging from using the libraries from the system (native mode) or a forced 32-bit mode. Only stable releases of library and software are added, with very few exceptions—such as Nvidia's Vulkan beta drivers.|

By default, Linux is a text/command-line based operating system. However, the Linux community has created varieties of desktop environments to offer a user-friendly GUI experience. Most include their own basic software for common use cases, such as a file explorer or word processor.
As a rule of thumb, environments with heavy RAM use typically add another 500 MB to the operating system's RAM requirements (which usually range from 500 MB to 4 GB), compared to environments with light RAM use.
One of the oldest desktop environments that is still continuously updated. Offers the most radical departure from the traditional Windows-style paradigm of start-menu-and-a-taskbar.
The first major comprehensive desktop environment released for Linux, which sees regular maintenance and feature updates. Out of the box, it offers a familiar Windows-like experience, but also allows nearly limitless ability to customize the functionality and look and feel of the desktop.
Created by a Solus developer and currently maintained by Solus Team. It serves as an alternative for GNOME with a much more desktop-like interface, which bears similarities to modern Windows.
Created by Linux Mint Team, Cinnamon offers an experience that is very similar to Windows 7.
Starting off as a clone of a Unix-like desktop environment called CDE, it became its own with a Windows XP-like appearance and light memory usage. XFCE is well-suited for low-end hardware and people who like to settle on one user experience and never change it (while still getting the security and maintinence updates).
MATE spawned as a spiritual successor to GNOME 2 after a controversial change in GNOME 3. It is recommended for Windows and Mac users while providing its own feature set such as mouse hover audio previewing.
LXDE (Lightweight X11 Desktop Environment) is a lightweight and fast, feature-rich desktop environment. It is designed to be user-friendly and slim, while keeping resource usage low. LXDE strives to be modular, so each component can be used independently with few dependencies.
Despite its limited features (as it is essentially a rewrite of LXDE with a different UI framework) along with the lack of compositor, it is perfectly suited for the lowest end hardware.
- Wikipedia page
- It is important to update the Linux kernel as new versions provide security updates, bugfixes, better performance, and support for hardware. A distro's repository contains all the supported versions for that distro.
There are two main releases of the official Linux kernel:
- Long Term Support (LTS) is slightly behind in terms of hardware support and features, but offers better stability and has longer support.
- Stable release (sometimes called the current release) offers the best hardware support and the newest features. It should be the default choice for a gaming machine and be avoided only if it causes issues.
Despite these differences, both releases offer the same security updates.
- This section is meant for advanced users, you can easily break your OS, if you don't know what you are doing!
While both stable and LTS Linux kernel releases can be used for gaming, there are also community-made ones which add features and improvements. These kernels may or may not improve one's gaming experience, and may require DKMS (dynamic kernel module support) versions of drivers and headers to make hardware usable with multiple kernels.
The most notable releases:
- For help with installing different kernels on a distro, consult the kernel's official website or the distro's knowledge base.
- It is advised to keep the current official kernel in case of issues.
- UKUU is an useful utility for swapping kernels on Ubuntu (and Ubuntu derivatives).
It is vital to install the microcode for the CPU as the manufacturer provides security and stability updates, although most often your distribution will push those updates directly to you. Most distributions use either package manager or some kind of firmware/drivers manager to update the microcode.
- Generally speaking, if you use AMD graphics, you're likely to have a flawless experience as AMD makes open source drivers available and Linux developers integrate them directly into the kernel.
- Generally speaking, if you use Nvidia graphics, you're likely to have to make some independent efforts to either install or enable Nvidia drivers, as Nvidia does not offer any open-source drivers which makes the distribution maintainers hesitant when it comes to packaging or enabling Nvidia drivers by default.
Nvidia's drivers are also of worse quality than either AMD's own Linux drivers or Nvidia's Windows driver, with features that exist in the Windows drivers missing in the same card's Linux driver. This is entirely Nvidia's choice, and Linux developers and maintainers can do almost nothing to rectify the consequences of Nvidia's behaviour.

1 - GCN 1 and 2 architecture support in AMDGPU is experimental.
2 - Do not use it on Intel HD 4000 series and newer GPU.
Generally, AMD/ATI users should use the open source driver as it provides the best performance and support compared to the proprietary ones, while Nvidia users should stick to the proprietary ones. There are some things to remember:
- Try not to install drivers from the GPU manufacturer's website unless forced to, as distro maintainers package the driver to be offered from the package manager.
- If forced to use Catalyst, Nvidia 173, or Nvidia 96 drivers, one must downgrade Xorg to the last supported version.
- Before using the open source driver one must install LLVM and Linux Firmware packages.
Ubuntu (and Ubuntu-derived distros such as Mint, Pop!_OS, and Neon)
sudo add-apt-repository <PPA repository> to add one. Make sure to run
sudo apt update in order to update the repository list after adding one.

To install Nvidia drivers on Fedora, it is usually sufficient to install the latest Nvidia drivers from the software center. Simply search for Nvidia and install the driver with the highest version number.
If you have a more complex setup, such as an Optimus laptop, or the above instructions do not work for you, you can also user 'NVIDIA Auto Installer for Fedora Linux'. It is a set of scripts which can handle both normal installs and more advanced configurations.
To use it, execute the following in the terminal:
sudo dnf install dnf-plugins-core -y && sudo dnf copr enable t0xic0der/nvidia-auto-installer-for-fedora -y && sudo dnf install nvautoinstall -y
Once installed, type in
nvautoinstall into your terminal. The program will show you the options you can use.
The most basic installation is performed by issuing the following command:
sudo nvautoinstall rpmadd && sudo nvautoinstall drive.
To install support for Vulkan API (will be functional only if you have a Vulkan capable GPU and driver), execute the following command
sudo dnf install vulkan-loader vulkan-loader.i686
If you used nvautoinstall above, you can also install Vulkan API via
sudo nvautoinstall vulkan.
- Nvidia Optimus Linux guide
- Optimus support in Nvidia GPUs is still considered to be troublesome.
In case of laptops which has Nvidia Optimus support, it is recommended to have PRIME enabled, which can be done by installing an additional package. Follow the distro’s documentation to set this up.
AMD users only require running the game with the
Linux has several sound systems available. The most common one is PulseAudio, but a new system called PipeWire is looking to supersede and consolidate all previous systems into one. For most games, PulseAudio will work.
In the case of MIDI, installing the Timidity or Fluidsynth package is required along with either a soundfont or the FreePats package. Depending on the distro, it will either be set up automatically or require manual intervention.

Linux supports a vast array of input devices, including legacy hardware. Many programs exist for gaming peripherals in case further customization is needed.
- Piper - Configure gaming mice
There are some other ones made for products from specific companies:
- OpenRazer - Open-source driver for Razer peripherals
- Polychromatic - Frontend for OpenRazer
- RazerGenie - Configurator for Razer mice, keyboard, headsets, and more
- RazerCommander - Razer device manager
- RazerCFG - A much more simplified configurator for Razer products
- Roccat Configurator - An official configurator for Roccat products
All DirectInput and XInput controllers are supported. In case of issues with XInput controllers, it is recommended to install xboxdrv.
If dealing with a game that has a very limited or no controller support at all, the AntiMicroX program offers a solution. It allows the user to bind keyboard and mouse inputs to the controller. However, it currently only works with Xorg.
Additionally, a user can use Steam Input in the Steam app to configure their controller.
- ext4 is the default file system used by most Linux distributions.
- While the file system used on Windows, NTFS, is supported, it is generally not recommended to use as it may cause compatibility issues.
The most important aspect of the disk partitioning is often the swap partition; it generally acts as RAM replacement. The absence of it will cause software to shut down due to low memory, and it is also used to offload memory from RAM when entering power saving modes such as Hibernation or Sleep. The size of the swap disk depends on how much RAM is available in the computer; if less than 8 GB of RAM, increase the swap disk, or if more than 8 GB of RAM, decrease the swap disk.
It is generally recommended to partition disks in this particular order:
- / (Root)
- Swap disk
A user can create multiple partitions for each directory with a specific disk size to use or use the entire free space on Root and leave some for swap.
- Wayland is newer than Xorg and is considered to be technically superior.
- Wayland is not supported by older proprietary games.
While Wayland offers more a modern and secure backend, Xorg has legacy support and will generally be more compatible than Wayland. In addition, Wayland is still in active development and is missing features that would provide a gaming experience in parity with Xorg.
Benchmarking in Linux can be achieved with the Phoronix Test Suite. It is easy to use despite not offering a user-friendly GUI. The biggest advantage is it saves the information as a webpage, making comparing tests much easier.
Steam users can use Valve's voglpref, which requires Steam.
Since Linux 3.9 and recent QEmu version, it is possible to passthrough a graphics card, motherboard, or even other hardware into a virtual machine. The main advantage of it is having a native GPU working on Windows in a virtual machine, which allows you to play Windows games on it while using Linux.
There are some disadvantages:
- A second GPU for PCI passthrough is required
- GPU must support UEFI
- CPU must support hardware virtualization and IOMMU
- Motherboard must support IOMMU
- It is not an easy process for beginners
Stores and clients
|Name||Client available||Registers Linux sales?||Notes|
|Game Jolt||Yes (Optional)||Unknown|
|Snap Store||Yes (Optional)||No|
Disable mitigations for transient execution CPU vulnerabilities
- Be aware that disabling these will cause your PC to be susceptible to multiple vulnerabilities such as Spectre, Meltdown, ZombieLoad etc. Use it with discretion.
- Outside of specific microbenchmarks, disabling the default mitigations should result into an average performance increase of 5-10%. The following parameter used in here is available only in 5.1.13 kernel or newer (or backports to 3.16.68, 4.4.180, 4.9.176, 4.14.119 and 4.19.43), for others see this parameters string.
|Edit the GRUB settings|
Open up the
Re-generate the grub.cfg using one of these commands as root:
grub-mkconfig -o /boot/grub/grub.cfg update-grub # Used by Ubuntu based distros, easy version of the 1st one.
Disable mouse acceleration in Xorg
- Some desktop environments offer an option to set up the mouse acceleration directly from the settings menu (Such as KDE Plasma, GNOME and later on MATE)
|Create a new Xorg rule|
Create a config file in /etc/X11/xorg.conf.d/ as
Section "InputClass" Identifier "My Mouse" Driver "libinput" MatchIsPointer "yes" Option "AccelProfile" "flat" EndSection
Then restart the system or Xorg (In most distros its Ctrl+Alt+Backspace ←)
Improve shutdown time in systemd
|Edit the system.conf|
In some desktop environments such as LXQt, the system shutdown or restart process may take longer due to Systemd having the time to stop the session set to 1 minute 30 seconds by default.
Install watchdog package and enable/run the watchdog service.
Resolution scaling with xrandr
It is entirely possible to scale the resolution through multiplications (
--scale) or by resolution (
xrandr command. Provided that you input the monitor name and your current resolution, which can be learned by using
xrandr -q command (It will also list available resolutions).
Here are some examples:
xrandr --output VGA1 --mode 1024x768 --scale 0.5x0.5- this will downscale the resolution by 0.5 while using 1024x768 resolution in VGA1 monitor.
xrandr --output VGA3 --mode 1920x1080 --scale-from 1440x900- This command will imitate the 1440x900 resolution under 1080p in your VGA3 monitor.
Use Feral Game Mode to improve the performance
- Most distros includes the software in their repository, it is recommended to install both 64 and 32 bit versions to apply in every game, if not, the source code can be found in the GitHub page.
- Supports custom scripts
- Developers can use it to implement in their games.
Feral Game Mode is used by Feral Interactive to provide optimization in their games (From Rise Of The Tomb Raider) when being ran, it provides changes to these following processes:
- CPU governor
- Input/Output priority
- Process niceness
- Kernel scheduler
- Screensaver inhibiting
- GPU performance mode (Nvidia and AMD), GPU overclocking (Nvidia)
Once the package is installed, you can activate it when running other games with
gamemoderun *game executable/launcher*, on Steam add
gamemoderun %command% into Launch Options.
Enable 32-bit support for your distro
|Enable 32-bit library support in Ubuntu/Debian based distros|
As Ubuntu/Debian 64-bit distros have 32-bit libraries disabled by default, this can cause compatibility issues with the software (Especially with upgrading Wine). To enable it you must use these following commands:
sudo dpkg --add-architecture i386 sudo apt update
List missing dependencies
|List the missing dependencies|
As GOG, Steam and other stores mostly support Ubuntu due to its popularity in both making another distribution (Such as Linux Mint) or wide use, there can be a limited support for the other distros such as Arch Linux, Fedora, etc. Mostly in terms of requiring dependencies to run the game or a software.
ldd <binary file>
After running the command, it'll list all the *.so files the software uses, if there is a "Not found" somewhere, this is the moment to learn which package does it contain the file.
The missing dependency checkup can be even easier with the inclusion of the
ldd <binary_file> | grep "Not found"
This will only look for the lines related to "Not found" only, if nothing shows up then you have everything you need.
|Improve compiling speed in AUR (Manjaro, EndeavourOS, Arch Linux)|
Open makepkg.conf as root and under MAKEFLAGS add
Create a script which the game uses libraries from your system instead
|Make a native executable for your game|
#!/bin/sh LD_LIBRARY_PATH=/path/to/library /path/to/executable
4. Once done, save it and make it executable using either
|The Nvidia DKMS driver won't install after updating it|
|Set up a primary monitor in multi-monitor setup|
|No sound|
Open the Terminal and type as root
|Crackling sound/audio delay in PulseAudio|
Type in terminal this command to stop and then start PulseAudio at the same time:
pulseaudio -k && pulseaudio --start
Nvidia users can fix the screen tearing by enabling Force Composition Pipeline in Nvidia Settings, if it persists, enable Force Full Composition (Keep in mind that it reduces the performance in games even more).
AMD and Intel HD users do not have to do anything as DRI3 handles the refresh rate by default without compromising the performance, provided the compositor contains the Present extension.
If it persists, chances are you may be required to install and use a 3rd party compositor such as Compiz, Compton etc.
