Puppy Linux is a lightweight Linux distribution designed to run efficiently on both modern and older computers. Unlike many Linux distributions, Puppy is designed to be fast, portable, and capable of running entirely from RAM, resulting in quick boot times and responsive performance.

Some notable features include:

• Extremely small download size
• Low memory usage
• Runs entirely from RAM (on systems with sufficient memory)
• Can operate without a traditional installation
• Excellent support for older hardware
• Easy backup through save files or save folders
• Includes a large collection of built-in applications

Several Puppy Linux variants are available, each built on different package ecosystems.

Popular choices include:

• Ubuntu-based Puppy (compatible with Ubuntu packages)
• Debian-based Puppy (compatible with Debian repositories)
• Slackware-based Puppy
• Official Puppy Linux community releases

When selecting a version, consider:

• Hardware age
• Required software compatibility
• Available RAM
• Processor architecture (64-bit or 32-bit)

For most modern systems, a recent 64-bit release is recommended.

Requirements

• USB flash drive (4 GB or larger)
• Internet connection
• ISO image
• USB writing utility

Download the desired Puppy Linux ISO. Verify the checksum if one is provided. Create a bootable USB using your preferred imaging utility.

1. Insert the USB drive
2. Enter the computer’s boot menu
3. Select the USB device
4. Boot Puppy Linux.

Most versions present a boot menu with default options.Choose the default entry unless you require special hardware options.

Puppy usually starts directly into the desktop. Unlike many Linux distributions, you are often logged in automatically.

The desktop typically includes:

• File manager
• Terminal
• Browser
• Package Manager
• Setup Wizard
• System utilities

Run the setup wizard if it does not start automatically.

Configure:

• Keyboard layout
• Display resolution
• Time zone
• Language
• Locale

• Main Puppy SFS file
• Additional SFS modules if required

Install a bootloader.

Most recent systems use GRUB.Legacy BIOS systems may use GRUB Legacy or GRUB4DOS depending on the Puppy version.Reboot.

One unique Puppy Linux feature is persistent storage.When shutting down for the first time, Puppy asks whether to save your session.Options include:

Advantages:

• Portable
• Easy backup
• Fixed size

Typical sizes:

• 512 MB
• 1 GB
• 2 GB
• Larger as needed

Advantages:

Generally preferred on Linux-native filesystems.

Important directories include:

/root

Default home directory.

/mnt

Mounted drives.

/etc

System configuration.

/usr

Applications.

/var

Logs and runtime data.

Unlike rolling distributions, Puppy updates vary depending on the specific release.

Recommended approach:

• Update package repositories
• Install security updates when available
• Upgrade individual applications as needed
• Consider upgrading to a newer Puppy release periodically.

Open Puppy Package Manager.

Features include:

• Search packages
• Install software
• Remove packages
• Manage repositories
• View dependencies

Depending on the Puppy variant, packages may originate from:

• Ubuntu
• Debian
• Slackware
• Puppy repositories

Examples include:

Development:

• GCC
• Make
• CMake

Office:

• LibreOffice

Graphics:

• GIMP
• Inkscape

Media:

• VLC
• Audacity

Development tools:

• Git
• Python
• Node.js

Many Puppy releases include a lightweight browser.

Alternatives include:

• Firefox
• Chromium
• Pale Moon (where available)
• Other compatible browsers

Install using the Puppy Package Manager or the package format supported by your Puppy variant.

Open:

Setup → Sound Wizard

Verify:

• Audio output
• Microphone
• Volume levels

Use the mixer utility to adjust sound levels.

Open:

Printer Setup

Typical workflow:

1. Detect printer.
2. Install drivers if necessary.
3. Configure the printer.
4. Print a test page.

Many network printers are automatically detected.

Open the display configuration utility.

Adjust:

• Resolution
• Refresh rate
• Multi-monitor settings (if supported)
• Screen orientation

Apply and test changes.

Most hardware drivers are included in the Linux kernel.For proprietary graphics or wireless hardware, consult the documentation for your Puppy Linux variant to determine whether additional drivers are available.After installation, reboot if prompted.

For software development, install:

• GCC
• G++
• Make
• Git
• CMake
• Python
• OpenJDK (if needed)

Many Puppy releases also provide a “devx” SFS module containing compilers and development libraries that can be loaded without permanently installing every development package.

Applications can be started automatically during login.

Common startup items include:

• Cloud synchronization
• Clipboard managers
• Custom scripts
• Monitoring tools

Review the startup configuration provided by your Puppy version before adding applications.

Recommended backup strategy:

• Backup the save file or save folder regularly
• Backup personal files separately
