Ubuntu Scripts

Practical scripts for Ubuntu 22 LTS that actually work and solve real problems.

What's included

🛡️ Chrome Guardian System

chrome-guardian.sh - Monitors Chrome and automatically restarts it when it crashes. Because Chrome crashes a lot.

chrome-indestructible.sh - Restarts Chrome with anti-crash settings. Kills all Chrome processes first and cleans cache.

check-guardian.sh - Check guardian status and clean up duplicate processes.

🖥️ System Fixes

fix-screen-share.sh - Fixes screen sharing in Ubuntu 22 when it stops working (especially in Wayland). Doesn't close your apps.

💬 App Updaters

discord-updater.sh - Updates Discord to the latest version automatically.

⚙️ Setup & Management

install.sh - Automated installer that sets up everything and configures aliases.

Quick Installation

git clone https://github.com/0xjesus/ubuntu-scripts.git
cd ubuntu-scripts
./install.sh
source ~/.zshrc

Available Commands

After installation, these commands are available from anywhere:

bash

fix-screen      # Fix screen sharing issues
restart-chrome  # Restart Chrome with crash protection
start-guardian  # Start Chrome crash monitor
stop-guardian   # Stop Chrome crash monitor

How we use them

• Chrome Guardian: Runs in background monitoring Chrome crashes and auto-restarts
• Screen Share Fix: Essential for Zoom/Teams meetings when sharing stops working
• Discord Updater: Keep Discord up to date without manual downloads
• Guardian Checker: Prevent duplicate guardians from running

Features

• ✅ Smart Installation - Detects your shell (bash/zsh) and configures automatically
• ✅ Syntax Testing - All scripts are tested before installation
• ✅ No Duplicates - Guardian checker prevents multiple instances
• ✅ Verbose Logging - Know exactly what's happening
• ✅ Safe Operations - Won't close your apps unexpectedly

Requirements

• Ubuntu 22 LTS (primary target)
• Works with bash or zsh
• Some scripts require sudo for system operations

Troubleshooting

• If aliases don't work: source ~/.zshrc (or ~/.bashrc)
• If guardian isn't working: check-guardian to diagnose
• If screen sharing fails: fix-screen and restart your meeting app
• Check logs in the repo directory for detailed information

Works best on Ubuntu 22 LTS with Wayland. Your mileage may vary on other distros.
