Creating Custom Configuration

Generate Default Configuration

## Create config directory
mkdir -p ~/.config/neofetch

## Generate default configuration
neofetch --config > ~/.config/neofetch/config.conf

Key Configuration Options

Category	Customization Options
Display	Information order
Modules	Enable/disable system info
Colors	Custom color schemes
ASCII	System logo selection

Advanced Configuration Techniques

Selective Information Display

## Modify config to show specific info
info "OS" distro
info "Kernel" kernel
info "Uptime" uptime

Color Customization

## Example color configuration
colors=(distro)
## color_blocks="on"
## block_range=(0 15)

Troubleshooting Configuration Errors

Syntax Validation

## Check configuration syntax
neofetch --config ~/.config/neofetch/config.conf

Performance Optimization

Reducing Information Load

## Minimize system information display
neofetch --disable cpu gpu memory

LabEx Learning Environment

LabEx offers interactive Linux environments to practice and master Neofetch configuration techniques.

Best Practices

Always backup original configuration
