Install Fluxer

Arch Linux

Adds the [fluxer] pacman repo (key fingerprint verified), installs fluxer or fluxer-canary, writes GPU-aware flags.

Edition

One-line install

curl -fsSL https://fluxer.systux.xyz/arch.sh | bash

Same command in bash, zsh, fish and sh — only curl and bash need to be installed.

Read the script ↗

Open a terminal (Ctrl+Alt+T, or search “Terminal” in your launcher).
Paste the command above and press Enter.
Type your password when sudo asks, then launch Fluxer from the app menu (quit any running copy first).

Prefer manual steps?

sudo pacman-key --init
curl -fsSL -o /tmp/fluxer.asc https://pkgs.fluxer.com/keys/fluxer-archive-keyring.asc
sudo pacman-key --add /tmp/fluxer.asc
# verify fingerprint 09D01339EE128925F75E675C855C5BDE34D205D2, then:
sudo pacman -Syu --needed fluxer-canary

iPhone — TestFlight beta

Fluxer for iOS ships as an Apple TestFlight beta, so it takes two installs: TestFlight itself, then the beta.

1 · Get TestFlight 2 · Join the beta

Install TestFlight (free, by Apple) — first button.
On your iPhone, open the invite and tap Accept → Install.
Open the Fluxer beta, point it at this instance (below), then log in.

Betas expire after 90 days — re-install from the same link when TestFlight prompts you.

Android — beta

Not on Google Play. Two builds exist and they differ in one thing only: how push notifications reach your phone. They are separate installs — one replaces the other, so pick one and stay with it.

How should notifications arrive?

Firebase (FCM) Phones with Google Play services — Pixel, Samsung, almost anything off the shelf. Nothing to set up. UnifiedPush Degoogled phones — GrapheneOS, CalyxOS, /e/OS. Needs a UnifiedPush distributor set up separately.

Recommended — Obtainium

Obtainium installs the beta and keeps it updated, so you never have to hunt down a new APK. Install it first, then tap the button below on your phone.

Or download an APK directly

Almost every phone made since 2016 takes arm64-v8a. Not sure? universal works everywhere — it is just much larger. You repeat this download on every update.

armeabi-v7a 88 MB Download

universal 260 MB Download

Sizes are from the current beta and shift a little between releases — fluxer.app/download/android always has the live list.

Verify the signature

Every Android release build is signed with the certificate identified by this SHA-256 fingerprint. Check it before installing a file you did not download from this page:

91:E4:98:E1:B8:A6:C8:BA:99:41:5E:DB:29:78:29:6B:6C:58:BA:A5:E2:D2:A6:49:CE:C6:2D:A7:A8:29:C7:BC

Point the app at this instance

Mobile builds default to fluxer.app. The login screen tells you which instance it is talking to:

Login screen with the Change instance button circled — 1 — tap **Change** under the login form

Connect to instance sheet with the URL field and Connect button marked — 2 — enter `fluxer.systux.xyz`, tap **Connect**

Tap a screenshot to enlarge it.

What the script does

Adds the official pkgs.fluxer.com pacman repository — the signing key's fingerprint is verified before import.
Installs the desktop app from that repository.
Detects Wayland/X11 and NVIDIA/Intel/AMD, then writes matching Chromium flags.
Points the app at your instance through a .desktop override — no system files are touched.

Piping a script to a shell? Read it first — every installer is plain text at /scripts/. Advanced knobs: DESKTOP_ONLY=1, ASSUME_YES=1, GPU=, SESSION=, EXTRA_FLAGS=.

Debian / Ubuntu	`curl -fsSL https://fluxer.systux.xyz/debian.sh \| bash`	Read

iPhone: install TestFlight, then join the beta.

Android: pick the FCM build for a phone with Google Play services, or the UnifiedPush build for a degoogled one — every architecture is listed at fluxer.app/download/android. Obtainium keeps whichever you choose up to date.

Both mobile builds default to fluxer.app: on the login screen tap Change, enter fluxer.systux.xyz and tap Connect.
