mindesbunister 2edb4a73c3 Complete Linux system optimization suite with tmpfs, zram, and German locale support
- Fixed missing setup_tmpfs() function that was causing silent failures
- Added comprehensive system scanning for browsers, IDEs, gaming caches
- Implemented detailed optimization information display for transparency
- Added German locale compatibility for 'free' command (Speicher: vs Mem:)
- Fixed division by zero errors in RAM calculations
- Created tmpfs-info.sh helper script for detailed status reporting
- Enhanced scanning to work on already-optimized systems
- Added comprehensive optimization breakdowns with purpose explanations

Enhanced System Optimization Scanner

🎯 Additional Scanning Opportunities Implemented

1. Extended Browser Support

Now scans for additional browsers:

  • Microsoft Edge (~/.cache/microsoft-edge)
  • Brave Browser (~/.cache/brave)
  • Opera (~/.cache/opera)
  • Vivaldi (~/.cache/vivaldi)

2. Development Tool Caches

Node.js/JavaScript:

  • NPM cache (~/.npm) - Can be 1GB+
  • Node modules and build caches

Python Development:

  • pip cache (~/.cache/pip) - Python packages
  • Virtual environment caches

IDE/Editor Caches:

  • VS Code (~/.vscode) - Extensions and workspace cache
  • JetBrains IDEs cache (can add later)

3. KDE/Plasma Desktop Environment

KDE-Specific Caches:

  • Baloo indexer (~/.cache/baloo) - File search index (500MB+)
  • Plasma shell cache (~/.cache/plasma*)
  • KRunner cache (~/.cache/krunner) - Application launcher
  • KDE system cache (~/.cache/ksycoca5*)
  • GPU shader cache (~/.cache/mesa_shader_cache) - Important for gaming!

Smart KDE Detection:

  • Automatically detects KDE/Plasma environment
  • Creates dedicated tmpfs mount for KDE caches
  • Sizes tmpfs appropriately based on profile

4. Enhanced tmpfs Mount Structure

/tmp/tmpfs-cache/
├── browser/        # All browser caches
├── ide/           # Editor/IDE caches  
├── packages/      # Package manager caches
├── thumbnails/    # File manager thumbnails
├── development/   # Development tool caches (npm, pip, etc.)
└── kde/          # KDE/Plasma specific caches (if detected)

🚀 Future Enhancement Opportunities

High-Priority Additions

1. Gaming Optimizations:

# Steam and gaming caches
~/.steam/steam/appcache
~/.local/share/Steam/steamapps/shadercache  # GPU shader cache - CRITICAL!
~/.cache/lutris
~/.cache/wine

2. More Development Tools:

# Container systems
~/.docker/              # Docker user cache
~/.cache/podman        # Podman cache
/var/lib/docker/tmp    # Docker build cache

# Build systems
~/.gradle/caches       # Gradle cache (Java/Android)
~/.m2/repository       # Maven repository 
~/.cache/go-build      # Go build cache
~/.cargo/registry      # Rust cargo cache

3. GNOME Desktop Environment:

~/.cache/gnome-shell   # GNOME Shell cache
~/.cache/tracker       # GNOME file indexer
~/.cache/evolution     # Email client
~/.cache/gstreamer-1.0 # Media framework

4. Package Manager Extensions:

# Universal package managers
/var/lib/flatpak       # Flatpak apps (can be GB!)
/var/lib/snapd/cache   # Snap packages
~/.local/share/flatpak # User Flatpak apps

# Distribution-specific
/var/cache/pacman/pkg  # Arch Linux
/var/cache/yum         # RedHat/CentOS  
/var/cache/dnf         # Fedora
/var/cache/zypper      # OpenSUSE

Advanced Features to Consider

1. Intelligent Profile Detection:

  • Gaming profile: Detect Steam, shader caches
  • Development profile: Detect IDEs, build tools
  • Media profile: Detect video editors, large media caches

2. GPU-Specific Optimizations:

  • NVIDIA shader cache optimization
  • AMD graphics cache handling
  • Intel integrated graphics optimizations

3. SSD-Specific Features:

  • SSD wear leveling considerations
  • TRIM optimization
  • Temporary file placement strategies

4. Network-Based Optimizations:

  • Download cache consolidation
  • Torrent client cache management
  • Browser download folder optimization

📊 Current Implementation Benefits

Smarter Detection:

  • Scans 6 browsers instead of 3
  • Detects development environment automatically
  • KDE environment awareness
  • More accurate cache size calculations

Better Recommendations:

  • Profile suggestions based on actual cache patterns
  • Desktop environment-specific optimizations
  • Development workload detection

Enhanced Persistence:

  • Environment-aware mount restoration
  • Proper tmpfs sizing for detected workloads
  • More granular cache categorization

🎯 Next Steps to Implement

  1. Gaming Detection: Add Steam/shader cache scanning
  2. GNOME Support: Add GNOME-specific cache detection
  3. Container Detection: Add Docker/Podman cache scanning
  4. Build Tool Detection: Add Gradle/Maven/Cargo cache scanning
  5. GPU Optimization: Add shader cache prioritization

The enhanced scanner now provides much more intelligent analysis and recommendations based on the user's actual desktop environment and usage patterns!
