GNOME Caffeine¶

Description¶

This role installs caffeine-ng, a utility that prevents your GNOME desktop from entering sleep mode or activating the screensaver automatically. It also ensures that caffeine-ng is set to autostart at user login.

Overview¶

This role installs caffeine-ng and configures it to autostart for preventing screen sleep on GNOME.

Cosmos¶

The diagram places GNOME Caffeine in the Infinito.Nexus cosmos: the components it deploys (capabilities), the central services it consumes (dependencies), and its outward reach (federation and bridged external networks).

    end

Solid 1:1 edges are fixed relationships; dashed 0..1 edges are conditional (enabled only in matching deployments); red 0..0 edges are turned off in this role. Node markers show the role’s deploy modes (💻 host, 🐳 compose, 🐝 swarm); ❌ marks a service that is explicitly turned off, and ⚙️ an Ansible role dependency declared in meta/main.yml.

Purpose¶

The purpose of this role is to ensure uninterrupted workflow by keeping the desktop active during long-running tasks or presentations. By automatically starting caffeine-ng, it prevents unwanted screen locking or sleep modes on GNOME systems.

Features¶

Installs caffeine-ng from the AUR using an AUR helper.
Creates the autostart directory if it does not exist.
Deploys a customized desktop entry to ensure caffeine-ng starts automatically.
Enhances user experience by maintaining an active desktop environment.

Quick Setup¶

Development¶

Clone, set up the workstation, and deploy GNOME Caffeine onto the local stack:

git clone https://github.com/infinito-nexus/core.git
cd core
make onboard
make compose-deploy mode=reinstall apps=desk-gnome-caffeine full_cycle=false

Production¶

Install GNOME Caffeine directly onto the target machine: clone the repository, install the OS prerequisites and the repository toolchain, then deploy against localhost over a local connection (no SSH, no container):

git clone https://github.com/infinito-nexus/core.git
cd core
bash scripts/install/package.sh
make install
source scripts/meta/env/load.sh

APP=desk-gnome-caffeine
DOMAIN=<your-domain>
TLS_MODE=self_signed
SSH_PUBLIC_KEY="<your-ssh-public-key>"
INVENTORY=inventories/production
infinito administration inventory provision "$INVENTORY" \
  --inventory-file "$INVENTORY/devices.yml" \
  --host localhost \
  --include "$APP" \
  --vars "{\"TLS_MODE\": \"$TLS_MODE\", \"DOMAIN_PRIMARY\": \"$DOMAIN\", \"users\": {\"administrator\": {\"authorized_keys\": [\"$SSH_PUBLIC_KEY\"]}}}"
infinito administration deploy dedicated "$INVENTORY/devices.yml" \
  --password-file "$INVENTORY/.password" \
  --diff -vv
