# Changelog
|
||||||
|
|
||||||
|
## [2025-09-23] - tmpfs Setup Fix
|
||||||
|
|
||||||
|
### Fixed
|
||||||
|
- **one-button-optimizer.sh**: Fixed critical issue where tmpfs setup was not working
|
||||||
|
- Added missing `setup_tmpfs()` function that was referenced but not implemented
|
||||||
|
- Enhanced tmpfs analysis to actually scan system for cache directories
|
||||||
|
- Added intelligent profile recommendation based on RAM size and existing cache data
|
||||||
|
- Fixed tmpfs persistence by generating proper fstab entries
|
||||||
|
- Updated systemd service to restore tmpfs mounts after reboot
|
||||||
|
|
||||||
|
### Enhanced
|
||||||
|
- **tmpfs Analysis**: Now scans for actual cacheable data:
|
||||||
|
- Browser caches (Chrome, Firefox, Chromium)
|
||||||
|
- Package caches (/var/cache/apt)
|
||||||
|
- Temporary files
|
||||||
|
- Shows actual cache sizes and provides intelligent recommendations
|
||||||
|
|
||||||
|
### Technical Details
|
||||||
|
- **Issue**: When users selected "yes" for tmpfs setup, nothing happened because the `setup_tmpfs` function was missing
|
||||||
|
- **Root Cause**: The function was called in main() but never defined
|
||||||
|
- **Solution**: Implemented complete tmpfs setup with intelligent sizing and persistence
|
||||||
|
|
||||||
|
### Testing
|
||||||
|
- Added test script (`test-tmpfs-fix.sh`) to verify functionality
|
||||||
|
- Confirmed syntax validation passes
|
||||||
|
- Verified tmpfs analysis logic works correctly
|
||||||
|
|
||||||
|
## Previous versions
|
||||||
|
- Initial implementation with zram, kernel tuning, and basic tmpfs detection

|
||||||
|
|
||||||
|
### **Different System Types**
|
||||||
|
|
||||||

```
|
||||||
|
|
||||||
|
### **Custom Optimizations**
|
||||||

# Enhanced tmpfs Information Display
|
||||||
|
|
||||||
|
## 🎯 **What Was Enhanced**
|
||||||
|
|
||||||
|
### **1. Detailed Setup Information**
|
||||||
|
The one-button optimizer now shows **exactly what it's putting into RAM**:
|
||||||
|
|
||||||
|
```
|
||||||
|
📋 tmpfs Setup Details:
|
||||||
|
======================
|
||||||
|
|
||||||
|
🔧 Created tmpfs mount points:
|
||||||
|
📁 /tmp/tmpfs-cache/browser - Size: 4194304k
|
||||||
|
📁 /tmp/tmpfs-cache/ide - Size: 2097152k
|
||||||
|
📁 /tmp/tmpfs-cache/packages - Size: 3145728k
|
||||||
|
📁 /tmp/tmpfs-cache/thumbnails - Size: 524288k
|
||||||
|
📁 /tmp/tmpfs-cache/development - Size: 2097152k
|
||||||
|
📁 /tmp/tmpfs-cache/kde - Size: 1048576k
|
||||||
|
|
||||||
|
💡 How to use these optimizations:
|
||||||
|
|
||||||
|
🌐 Browser Cache (/tmp/tmpfs-cache/browser):
|
||||||
|
• Chrome: Set cache to /tmp/tmpfs-cache/browser/chrome
|
||||||
|
• Firefox: Set cache to /tmp/tmpfs-cache/browser/firefox
|
||||||
|
|
||||||
|
💻 Development Cache (/tmp/tmpfs-cache/development):
|
||||||
|
• NPM: npm config set cache /tmp/tmpfs-cache/development/npm
|
||||||
|
• Pip: export PIP_CACHE_DIR=/tmp/tmpfs-cache/development/pip
|
||||||
|
• Docker: Configure build cache to use this mount
|
||||||
|
|
||||||
|
🎨 IDE Cache (/tmp/tmpfs-cache/ide):
|
||||||
|
• VS Code: Link ~/.vscode to /tmp/tmpfs-cache/ide/vscode
|
||||||
|
• JetBrains: Configure temp/cache directories
|
||||||
|
|
||||||
|
🖥️ KDE Cache (/tmp/tmpfs-cache/kde):
|
||||||
|
• Baloo: kwriteconfig5 --file baloofilerc --group 'Basic Settings' --key 'Indexing-Enabled' false
|
||||||
|
• Thumbnails: Link ~/.cache/thumbnails to /tmp/tmpfs-cache/kde/thumbnails
|
||||||
|
• Plasma cache: Automatically used by system
|
||||||
|
|
||||||
|
📦 Package Cache (Automatically configured):
|
||||||
|
• APT cache is already bound to /var/cache/apt → tmpfs
|
||||||
|
• Reduces SSD wear during package operations
|
||||||
|
|
||||||
|
⚡ Performance Benefits:
|
||||||
|
• 🚀 Faster cache access (RAM speed vs SSD)
|
||||||
|
• 💿 Reduced SSD wear and tear
|
||||||
|
• 🧹 Automatic cleanup on reboot
|
||||||
|
• 🔋 Lower power consumption for cache operations
|
||||||
|
```
|
||||||
|
|
||||||
|
### **2. Enhanced Final Status Display**
|
||||||
|
Shows detailed usage information:
|
||||||

|
||||||
|
• development: 2048MB (0% used)
|
||||||
|
• kde : 1024MB (0% used)
|
||||||
|
📊 Total tmpfs allocated: 12800MB
|
||||||
|
⚙️ kernel: swappiness=1, dirty_ratio=3
|
||||||
|
🔄 service: enabled (will restore tmpfs on reboot)
|
||||||
|
|
||||||
|
🎯 Next Steps:
|
||||||
|
1. 🔄 Reboot to ensure all optimizations persist
|
||||||
|
2. 🌐 Configure applications to use tmpfs caches (see details above)
|
||||||
|
3. 📊 Monitor usage: df -h | grep tmpfs-cache
|
||||||
|
4. 🔍 Check status anytime: ./quick-status-check.sh
|
||||||
|
|
||||||
|
💡 Useful Commands:
|
||||||
|
• Check tmpfs usage: df -h /tmp/tmpfs-cache/*
|
||||||
|
• Monitor performance: iotop -ao
|
||||||
|
• View mount details: mount | grep tmpfs-cache
|
||||||
|
|
||||||
|
🚀 Your system now has 12800MB of high-speed cache storage in RAM!
|
||||||
|

# Enhanced System Optimization Scanner
|
||||||
|
|
||||||
|
## 🎯 **Additional Scanning Opportunities Implemented**
|
||||||
|
|
||||||
|
### **1. Extended Browser Support**
|
||||||
|
Now scans for additional browsers:

|
||||||
|
|
||||||
|
### **2. Development Tool Caches**
|
||||||
|
**Node.js/JavaScript:**
|
||||||
|
- NPM cache (`~/.npm`) - Can be 1GB+
|
||||||
|
- Node modules and build caches
|
||||||
|
|
||||||
|
**Python Development:**
|
||||||
|

|
|
||||||
|
### **High-Priority Additions**
|
||||||
|
|
||||||
|
**1. Gaming Optimizations:**
|
||||||
|
```bash
|
||||||
|
# Steam and gaming caches
|
||||||
|
~/.steam/steam/appcache
|
||||||
|
~/.local/share/Steam/steamapps/shadercache # GPU shader cache - CRITICAL!
|
||||||
|
~/.cache/lutris
|

|
||||||
|
- 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!

# Linux System Tuning Suite
|
||||||
|
|
||||||
|
🚀 **Intelligent system optimization toolkit for Linux desktop systems**
|
||||||
|
|
||||||
|
This repository provides automated system tuning based on hardware detection, usage patterns, and best practices for tmpfs, overlay filesystems, and kernel parameter optimization.
|
||||||
|
|
||||||
|
## ✨ **NEW: One-Button Optimizer**
|
||||||
|
|
||||||
|
🎯 **Quick Start:** `sudo ./one-button-optimizer.sh`
|
||||||
|
|
||||||
|
The **one-button optimizer** is an intelligent, interactive system optimizer that:
|
||||||
|
|
||||||
|
- 🔍 **Analyzes current optimizations** and detects suboptimal configurations
|
||||||
|
- 🤔 **Prompts for user choice** on each optimization
|
||||||
|
- 🎯 **Applies only selected optimizations** - no forced changes
|
||||||
|
- ✅ **Recognizes existing optimal configurations** and leaves them alone
|
||||||
|
- ⚙️ **Handles mixed scenarios** where some optimizations exist but aren't ideal
|
||||||
|
|
||||||
|
### Quick Tools
|
||||||
|
|
||||||
|
- `./one-button-optimizer.sh` - **Main interactive optimizer** (recommended)
|
||||||
|
- `./quick-status-check.sh` - **Quick system status** overview (no changes)
|
||||||
|
- `./tmpfs-info.sh` - **Detailed tmpfs information** and configuration guide
|
||||||
|
- `./launcher.sh` - **Auto-sudo launcher** for the optimizer
|
||||||
|
|
||||||
|
## 🎯 Features
|
||||||
|
|
||||||
|
- **Hardware Detection**: Automatically detects RAM, CPU, storage configuration
|
||||||
|
- **Usage Analysis**: Identifies frequently accessed files and directories
|
||||||
|
- **Intelligent Tuning**: Applies optimizations based on system characteristics
|
||||||
|
- **Interactive Mode**: User control over what gets optimized
|
||||||
|
- **Suboptimal Detection**: Finds and offers to fix existing but suboptimal configs
|
||||||
|
- **Modular Design**: Easy to customize and extend
|
||||||
|
- **Safe Deployment**: Backup and rollback capabilities
|
||||||
|
- **Multi-Distribution**: Works across different Linux distributions
|
||||||
|
|
||||||
|
