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. Install TestFlight first, then open the invite link to install Fluxer.

TestFlight alone is not Fluxer. Install TestFlight, then press the invite code link below.

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

Android — beta

Not on Google Play. Choose the build that matches how notifications reach your phone.

Most phones: use FCM. GrapheneOS: use UnifiedPush.

Most phones · FCM Pixel, Samsung, and phones with Google Play. GrapheneOS · UnifiedPush For degoogled phones. Set up UnifiedPush first.

Optional — Obtainium updates

Obtainium can install the beta and keep it updated.

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

Connect Fluxer to this instance

Mobile builds default to fluxer.app. The screenshots show how to switch to this instance:

These screenshots show where to tap. They help you connect Fluxer after installing it — they are not another download.

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 either 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=.

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.
