If you have ever felt limited by GNOME Terminal’s sluggish rendering when tailing large log files or running a busy multiplexer session, you are not alone. Alacritty is a cross-platform, OpenGL-accelerated terminal emulator written in Rust that fixes exactly that problem. This guide covers how to install Alacritty on Fedora 43 using three different methods, so you can pick the path that fits your workflow, whether you prefer a one-command DNF install or a fully custom source build.

Fedora 43 ships Alacritty in its official repositories, which means most users can get up and running in under two minutes. By the end of this tutorial, you will have Alacritty installed, a desktop entry registered, and an optional baseline configuration ready to go.

What Is Alacritty and Why Use It on Fedora 43?

Alacritty is not trying to be a feature-rich terminal with built-in tabs and split panes. Its design philosophy is the opposite: stay minimal, stay fast, and delegate features like session management to dedicated tools such as tmux or Zellij.

Here is what makes Alacritty worth using on Fedora 43:

• GPU rendering via OpenGL offloads text rendering from the CPU, which results in noticeably smoother scrolling through large outputs
• Vi mode lets you navigate and copy text entirely from the keyboard
• Full-text search works across the entire scrollback buffer
• Regex Hints let you click or keyboard-select URLs, file paths, and other patterns without a mouse plugin
• Single-process multi-window model keeps RAM usage lower than running multiple terminal instances
• Native support for both Wayland and X11, which matters because Fedora 43 defaults to a Wayland session

Alacritty does carry an official “beta” label on its website, but the reality is that it has been a reliable daily driver for developers and sysadmins for years. The beta tag reflects the project’s commitment to not shipping half-finished features, not instability.

Prerequisites

Before you start, confirm the following:

• Fedora 43 installed (run cat /etc/fedora-release to verify)
• A user account with sudo privileges
• An active internet connection
• A GPU with OpenGL support (Intel integrated, AMD, and NVIDIA all work; NVIDIA Wayland users may need EGL drivers, covered in the troubleshooting section)
• Git installed if you plan to build from source (sudo dnf install git)
• Basic comfort working in a terminal

Run a full system update before you install anything:

sudo dnf upgrade --refresh

This prevents dependency conflicts and ensures your package metadata is current.

Step 1: Install Alacritty via DNF (Recommended Method)

This is the fastest and most stable path for the majority of Fedora 43 users. The official Fedora repository ships Alacritty 0.15.1, which is built and tested against Fedora 43’s libraries and receives security patches through the standard dnf upgrade pipeline.

Step 1.1: Run the Install Command

sudo dnf install alacritty

DNF resolves all dependencies automatically. You will see a transaction summary listing the Alacritty package and any required libraries. Type y and press Enter to confirm.

Expected output (last few lines):

Installed:
  alacritty-0.15.1-1.fc43.x86_64

Complete!

Step 1.2: Verify the Installation

alacritty --version

Expected output:

Alacritty 0.15.1

Also confirm the binary location:

which alacritty

This should return /usr/bin/alacritty. If it does, the binary is correctly on your $PATH.

Step 1.3: Launch Alacritty

From any existing terminal:

alacritty &

The & runs Alacritty as a background process so it does not block your current shell. You can also open it from GNOME Activities by searching “Alacritty” since the DNF install automatically registers the desktop entry.

Why DNF is the recommended method: You get automatic security updates, no compiler toolchain required, and a package that has been tested against Fedora 43’s exact library versions. Unless you need a feature from the latest upstream commit, this is the right choice.

Step 2: Install Alacritty via Cargo (Build from Source)

Use this method if you need the absolute latest upstream version or want to compile a Wayland-only or X11-only binary to reduce the footprint. Building from source takes more steps but gives you full control over the build.

Step 2.1: Install Build Dependencies

Alacritty is written in Rust but links against several system C libraries. Install them first:

sudo dnf install cmake freetype-devel fontconfig-devel libxcb-devel libxkbcommon-devel g++

Here is what each package does:

If you are on NVIDIA with Wayland, add one more package:

sudo dnf install mesa-libEGL-devel

Step 2.2: Install the Rust Toolchain via Rustup

The Rust package in Fedora’s DNF repo tends to lag behind the latest stable compiler. Rustup always gives you the current stable release:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Follow the on-screen prompts and select option 1 (default install). Then load the Cargo environment into your current shell:

source $HOME/.cargo/env

Set and update the stable channel:

rustup override set stable
rustup update stable

Verify both tools are available:

rustc --version
cargo --version

Step 2.3: Clone the Alacritty Repository

Always clone from the official upstream repository:

git clone https://github.com/alacritty/alacritty.git
cd alacritty

Step 2.4: Compile Alacritty

Standard build (supports both X11 and Wayland):

cargo build --release

If you want a Wayland-only binary (leaner, no X11 overhead):

cargo build --release --no-default-features --features=wayland

If you want an X11-only binary:

cargo build --release --no-default-features --features=x11

Expect the compilation to take between 3 and 10 minutes depending on your CPU and RAM. The compiled binary lands at target/release/alacritty.

Step 2.5: Copy the Binary to Your PATH

sudo cp target/release/alacritty /usr/local/bin

Verify:

alacritty --version

Step 2.6: Quick Cargo Install Alternative

If you only need the binary and do not care about the desktop entry, terminfo, or man pages, you can skip the clone and just run:

cargo install alacritty

Cargo downloads, compiles, and installs the binary to ~/.cargo/bin automatically. Make sure that directory is in your $PATH.

Step 3: Install Alacritty via Fedora COPR

COPR (Cool Other Package Repo) is Fedora’s community build service, similar in concept to Ubuntu’s PPAs. This method gives you a pre-built RPM that may be newer than the official Fedora repo, without requiring you to compile anything.

Important: COPR packages are community-maintained and are not officially supported or vetted by the Fedora Project. For production machines, stick with Method 1.

Step 3.1: Enable the COPR Repository

sudo dnf copr enable pschyska/alacritty

Step 3.2: Install Alacritty

sudo dnf install alacritty

Step 3.3: Verify

alacritty --version

Step 3.4: Optional — Disable the COPR Repo After Install

To prevent potential conflicts with future Fedora updates, you can disable the COPR repo after the install is complete:

sudo dnf copr disable pschyska/alacritty

Alacritty will remain installed; this just stops the repo from being queried on future dnf upgrade runs.

Note for Fedora Atomic (Silverblue, Kinoite) or Sway Atomic users: Use rpm-ostree instead of dnf:

rpm-ostree install alacritty

Then reboot to apply the layered package.

Step 4: Post-Installation Setup (Source and Cargo Builds Only)

DNF and COPR installs handle the following automatically. If you built from source, you need to do this manually.

Step 4.1: Install the Terminfo Entry

Without the correct terminfo, programs like Vim, tmux, and remote SSH sessions may display garbled output or missing colors.

Check if it is already installed:

infocmp alacritty

If that returns an error, install it:

sudo tic -xe alacritty,alacritty-direct extra/alacritty.info

Step 4.2: Register the Desktop Entry

This makes Alacritty appear in GNOME Activities:

sudo cp target/release/alacritty /usr/local/bin
sudo cp extra/logo/alacritty-term.svg /usr/share/pixmaps/Alacritty.svg
sudo desktop-file-install extra/linux/Alacritty.desktop
sudo update-desktop-database

Step 4.3: Install Man Pages

First, install the scdoc tool required to generate the man pages:

sudo dnf install scdoc

Then build and install:

sudo mkdir -p /usr/local/share/man/man1
scdoc < extra/man/alacritty.1.scd | gzip -c | sudo tee /usr/local/share/man/man1/alacritty.1.gz > /dev/null

Verify:

man alacritty

Step 4.4: Install Shell Completions

• Bash: Add source ~/alacritty/extra/completions/alacritty.bash to your ~/.bashrc
• Zsh: Copy extra/completions/_alacritty to a directory in your $fpath
• Fish: Copy extra/completions/alacritty.fish to $fish_complete_path[1]

Step 5: Configure Alacritty on Fedora 43

Alacritty works out of the box with zero configuration. But the real benefit comes when you tune it to your workflow. The Alacritty on Fedora 43 setup uses a single TOML file for all settings, and changes apply live when you save.

Step 5.1: Create the Config Directory and File

mkdir -p ~/.config/alacritty
nano ~/.config/alacritty/alacritty.toml

Step 5.2: Set Your Font

[font]
normal = { family = "JetBrainsMono Nerd Font", style = "Regular" }
size = 13.0

Replace "JetBrainsMono Nerd Font" with any font installed on your system. Run fc-list to see your available fonts.

Step 5.3: Set Window Padding and Opacity

[window]
opacity = 0.95
padding = { x = 10, y = 10 }

The opacity value accepts a float between 0.0 (fully transparent) and 1.0 (fully opaque). Note that transparency requires a compositor; on Wayland with GNOME, it works by default.

Step 5.4: Set a Color Scheme

Here is a minimal Catppuccin Mocha-inspired example:

[colors.primary]
background = "#1e1e2e"
foreground = "#cdd6f4"

Save the file, and Alacritty picks up the changes immediately without a restart.

Step 6: Troubleshooting Common Issues

Even a clean Fedora 43 system can throw a few curveballs. Here are the most common problems and how to fix them.

Problem 1: Alacritty Fails to Launch on NVIDIA Wayland

Symptom: A blank window appears and immediately closes, or Alacritty crashes on startup.

Fix: Install the EGL Mesa libraries:

sudo dnf install mesa-libEGL

As a temporary diagnostic test, force software rendering:

LIBGL_ALWAYS_SOFTWARE=1 alacritty

If that launches successfully, the problem is with your GPU driver setup, not Alacritty itself.

Problem 2: “alacritty: command not found” After Cargo Build

Cause: The binary is not in a directory on your $PATH.

Fix:

echo 'export PATH="$HOME/.cargo/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

Or, if you copied to /usr/local/bin, verify that path is in your $PATH:

echo $PATH | grep /usr/local/bin

Problem 3: Colors Look Wrong in SSH or Vim

Cause: The remote host does not have Alacritty’s terminfo entry installed.

Quick workaround:

export TERM=xterm-256color

Permanent fix: Copy the terminfo to the remote server:

infocmp alacritty | ssh user@remote-host -- tic -x -

Problem 4: No Title Bar on GNOME Wayland

This is expected behavior. Alacritty relies on the compositor for window decorations. On GNOME Wayland, this means no title bar by default.

Add client-side decorations to your config:

[window]
decorations = "full"

Problem 5: Cannot Find alacritty.info for Terminfo Install

This file only exists inside the cloned repository directory under extra/alacritty.info. Make sure you are running the tic command from inside the cloned alacritty/ folder, not from your home directory.
