android12-fastfetch

A Fastfetch config tuned for Android 12 / Termux and native X11 Termux desktops (XFCE, MATE, LXQt, …). It draws a fixed-width table with hardware, desktop, terminal, development, and uptime sections, then prints the color palette.

Actual fastfetch -c config.jsonc run on the author's Android 12 Termux phone — fixed-width bordered table: hardware → desktop → terminal → development → uptime, with the Gruvbox palette at the bottom. Rendered with plusafetch's ptycapture + ansi2png — numpy + Pillow, driven by a pty. Live state, not a template: RAM/battery/uptime drift between invocations.

What's included

• config.jsonc — the Fastfetch config (JSONC, comments allowed)
• ascii.txt — the penguin ASCII logo referenced by the config

Requirements

• fastfetch — 2.51.0 or newer (JSONC config format); tested on 2.71.0
• A terminal with UTF-8, a Nerd Font, and truecolor for the icons and borders
• On Termux: pkg install fastfetch (or build from source)
• Optional, for the Desktop section: xdpyinfo and xrandr (missing commands show Unknown instead of failing)

Before 2.51.0? The JSONC config format was not stable yet — upgrade with pkg update && pkg upgrade fastfetch, or fetch a release build from the fastfetch GitHub releases.

Install

Installer (backs up existing files)

bash install.sh              # fzf menu when available: full or minimal
bash install.sh --minimal    # nine-row preset instead

The installer writes ~/.config/fastfetch/config.jsonc and ~/ascii.txt, keeps timestamped backups of anything it replaces, and runs a render check. It records both files in $XDG_STATE_HOME/android12-fastfetch/installed.tsv; bash install.sh --uninstall removes them (or use --keep-logo).

Manual

git clone https://github.com/Mark44928/android12-fastfetch.git
cd android12-fastfetch

mkdir -p ~/.config/fastfetch
cp config.jsonc ~/.config/fastfetch/config.jsonc
cp ascii.txt ~/ascii.txt

fastfetch

Fastfetch reads ~/.config/fastfetch/config.jsonc by default. The config points the logo at ~/ascii.txt, so keep that path or edit logo.source.

Minimal preset

presets/minimal.jsonc keeps the logo and Gruvbox key color but trims the dashboard to nine rows (OS, kernel, uptime, packages, shell, terminal, memory, disk, date). Run it without replacing your main config:

fastfetch -c presets/minimal.jsonc --pipe

One-liner

mkdir -p ~/.config/fastfetch
curl -fsSL https://raw.githubusercontent.com/Mark44928/android12-fastfetch/main/config.jsonc -o ~/.config/fastfetch/config.jsonc
curl -fsSL https://raw.githubusercontent.com/Mark44928/android12-fastfetch/main/ascii.txt -o ~/ascii.txt
fastfetch

Customize

• Logo — edit logo.source in config.jsonc. Set "type": "builtin" to use Fastfetch's built-in logos instead. ascii.txt is a penguin-style ASCII logo kept in $HOME (see its provenance note in Notes).
• Disk folders — edit "folders" to match your storage. The default is /data:/storage/emulated/0 (internal storage, works on every device); run ls /storage to discover an SD-card mount point like /storage/0143-1A2B and add it, colon-separated.
• Colors — the config uses Gruvbox hex values. Change the {##...} colors to match your theme.
• Sections — remove or comment out modules you do not need (for example battery, gpu, localip, or wm).
• Key width — the cursor constants (\u001b[47D, \u001b[47C, …) assume a 47-column value block. If you change the labels or width, adjust those constants too.

Notes and troubleshooting

• The config is JSONC: comments are allowed. Fastfetch accepts it, but strict JSON tools may not.
• $schema is pinned to the 2.71.0 release tag — bump it (and re-run fastfetch) when you upgrade fastfetch, so schema drift cannot silently invalidate the config.
• In a plain Termux shell the Desktop-section rows (Session, Display, WM Theme, Icons, Terminal Font, Terminal Theme, X11 Backend) print Unknown — they are only meaningful under Termux:X11. Delete that section if you never use X11; the command modules inside it already gate themselves with system conditionals.
• The two GPU rows are intentional: GPU is the hardware model, G-Driver is the driver/version detail.
• The Hardware section (RAM, CPU, …) also renders correctly in plain Termux — only the desktop rows need X11.
• xdpyinfo comes from x11-utils on Debian/Ubuntu or the Termux X11 packages.
• Long values (CPU model, Terminal Font, Theme strings) can push past the 47-column value block and shift the right border — shorten the terminal font/theme values, or wrap them in a per-module format if your device shows misaligned rows.
• ascii.txt provenance: the penguin-style logo was assembled by the repo author from ASCII penguin art in the style of the classic pingu/cowsay lineage; it is a configuration asset covered by the repo's MIT license, not a stock fastfetch logo.
• The Disk row in the preview assumes the default /data:/storage/emulated/0 mount points; your disk module will print differently if you add a custom folders entry.

Changelog

Config v1.2.0

• Kernel row beside Chassis — running kernel release (uname -r)
• Load row in the Hardware section — 1/5/15-minute load averages, so the box's pressure is visible next to CPU and RAM (uptime and login rows stay in the Uptime section below)

Config v1.1.0

• Processes row in the Hardware section (process + thread count) — the label keeps the fixed-width alignment, and the module works on plain Termux CLI, not just X11
• $schema pinned to the 2.71.0 release tag instead of the moving dev branch, so schema drift cannot silently invalidate the config
• disk.folders defaults to /data:/storage/emulated/0 (works on every device) instead of the author's SD-card UUID, with a comment explaining how to add your own mount point
• Desktop section documented as X11-only, and the two GPU rows (hardware model vs driver version) explained
• ascii.txt provenance/language added to the license note
• CI actually runs fastfetch -c config.jsonc --pipe on a real 2.71.0 binary and asserts the RAM/CPU/Disk rows render
