This comprehensive guide reveals everything from installation to advanced customization, complete with real code examples and pro tips. Get ready to travel back to 1995 while keeping Linux's modern capabilities.

What Is Chicago95? The Ultimate Retro Linux Experience

Chicago95 is a meticulously crafted open-source theme that reimagines Microsoft's legendary 1995 operating system for modern Linux distributions. Created by GitHub user grassmunk, this project emerged from frustration with inconsistent Windows 95-inspired themes that failed to deliver a cohesive experience across GTK2, GTK3, and XFCE components.

The name "Chicago" references Windows 95's internal codename during development—a nod that true retro computing enthusiasts instantly recognize. Unlike superficial icon packs, Chicago95 represents a total conversion philosophy. It doesn't just skin your desktop; it fundamentally rearchitects the visual experience from boot splash to terminal prompt.

This theme has exploded in popularity among developers, retro computing fans, and content creators who crave distraction-free interfaces or need authentic 90s aesthetics for projects. The repository has become a collaborative hub where nostalgia meets modern Linux engineering, with contributors refining every pixel to match the original Windows 95 specifications.

What sets Chicago95 apart is its obsessive attention to detail. Every scrollbar, button, and menu has been recreated using original Windows 95 design documents and pixel-perfect measurements. The project includes not just visual themes but functional tools like Chicago95 Plus!—a theme installer compatible with original Microsoft Plus! theme files from the late 90s.

Key Features: A Technical Deep Dive

Chicago95 delivers a comprehensive theming ecosystem that goes far beyond simple color schemes. Let's explore the technical architecture that makes this possible.

Complete Icon Theme Integration

The project includes thousands of handcrafted icons that extend the Classic95 icon set. Each icon is rendered at multiple resolutions (16x16, 24x24, 32x32, 48x48, and scalable SVGs) using the PNG format for authenticity. The icon theme follows the FreeDesktop.org Icon Theme Specification, ensuring compatibility across hundreds of Linux applications. System icons, mimetypes, categories, and status indicators all receive the Windows 95 treatment, creating unprecedented visual consistency.

Dual-GTK Engine Architecture

Chicago95 employs separate but coordinated themes for GTK2 and GTK3 toolkits. The GTK2 theme leverages the pixbuf engine for accurate rendering of classic widgets, while the GTK3 version uses CSS styling that mimics the original Win32 API drawing routines. This dual-engine approach ensures that both legacy applications (like GIMP 2.x) and modern software (like GNOME apps) appear identical to their Windows 95 counterparts. The theme specifically targets GTK+ 3.22 and 3.24, covering 95% of current Linux distributions.

Enhanced XFWM Window Manager Theme

The included XFCE window manager theme modifies the original Redmond theme with over 50 refinements. Titlebar gradients, button spacing, border widths, and shadow effects have been adjusted to match Windows 95's exact specifications. The theme supports both active and inactive window states, with subtle color shifts that replicate the original behavior. Window controls (minimize, maximize, close) use authentic bitmap graphics at 1:1 scaling.

Chicago95 Plus! Theme Engine

This revolutionary tool parses original Microsoft Plus! theme files (.theme extension) and converts them on-the-fly for Linux compatibility. Written in Python 3, it extracts bitmaps, color schemes, and configuration data from vintage theme packs. The engine supports themes from Windows 95, 98, ME, and even early XP eras, automatically resizing assets and converting color palettes to GTK-compatible formats.

Plymouth Boot Splash System

The Plymouth theme is built from scratch using C and Plymouth Script. It displays the classic Windows 95 boot screen with authentic progress bars and the "Starting Windows 95" message. The theme includes fallback modes for systems without kernel mode setting (KMS) and supports both UEFI and legacy BIOS boot processes. Animation frames are timed to match the original boot sequence duration.

MS-DOS Inspired ZSH Theme

For terminal enthusiasts, Chicago95 includes a custom oh-my-zsh theme that replicates the MS-DOS command prompt. It features amber or green monochrome color schemes, classic DOS-style prompt formatting with drive letters, and custom ASCII art. The theme modifies prompt variables (PROMPT, RPROMPT) and includes alias configurations that mimic DOS commands (DIR, CD, CLS).

HiDPI Scaling Support

Modern 4K monitors receive partial support through scalable vector graphics and dynamic asset selection. The theme detects display DPI and loads appropriately sized resources, though some legacy bitmap elements may appear pixelated—a deliberate choice that maintains authentic 90s aesthetics.

LibreOffice Icon Theme

A partial icon theme for LibreOffice 6+ replaces modern toolbar icons with Windows 95-era equivalents. This covers common actions like save, print, copy, paste, and formatting, ensuring office applications blend seamlessly with the desktop environment.

Real-World Use Cases: Where Chicago95 Shines

1. Retro Computing Preservation Projects

Museums and educational institutions use Chicago95 to create period-accurate computing environments for exhibits about 90s technology. The theme allows them to run modern Linux on vintage hardware while maintaining historical authenticity. Archivists can demonstrate original software workflows without relying on unstable emulators or deteriorating physical hardware.

2. Distraction-Free Development Workspaces

Senior developers seeking cognitive simplicity deploy Chicago95 to eliminate modern UI clutter. The single-tasking aesthetic reduces context switching and notification fatigue. One developer reported 23% fewer interruptions after switching, attributing it to the lack of flashy animations and notification badges. The theme pairs perfectly with tiling window managers in floating mode for a "focused computing" experience.

3. OS History Curriculum Delivery

Computer science professors use Chicago95 to teach GUI evolution and HCI principles. Students can experience firsthand why Windows 95's interface decisions (start menu, taskbar, window chrome) revolutionized personal computing. The theme provides a living laboratory for studying skeuomorphic design, affordances, and the transition from command-line to graphical interfaces.

4. Content Creation for Retro Tech Channels

YouTubers producing "blast from the past" content use Chicago95 to create authentic screen recordings without violating Microsoft's Windows 95 license. The theme enables legally clean footage that captures the nostalgic essence. Channels focusing on vintage software reviews, OS comparisons, and tech history documentaries rely on Chicago95 for professional-grade visuals.

5. Legacy Application Interface Testing

Software engineers maintaining enterprise applications originally designed for Windows 95 use Chicago95 to test UI compatibility and user experience. Financial institutions and government agencies still running legacy systems can modernize their backend while preserving the familiar frontend interface that long-time employees depend on.

Real Code Examples from the Repository

Example 1: Repository Cloning Command

This fundamental command retrieves the complete Chicago95 source code:

# Clone the Chicago95 repository from GitHub
git clone https://github.com/grassmunk/Chicago95.git

# Change into the newly created directory
cd Chicago95

# List contents to verify download
ls -la

Explanation: The git clone command creates a local copy of the entire repository, including all themes, icons, scripts, and documentation. The HTTPS URL ensures compatibility with corporate firewalls and doesn't require SSH key setup. After cloning, changing directories lets you access the installation scripts and theme files immediately.

Example 2: Automated Installer Execution

The heart of Chicago95 is its Python-based installation engine:

# Grant execute permissions to the installer script
chmod +x Installer.py

# Execute the installer using Python 3 interpreter
python3 Installer.py

# For verbose installation with debug output
python3 Installer.py --verbose --debug

Explanation: The chmod +x command makes the Python script executable. The installer uses a text-based user interface (TUI) built with the curses library, presenting menu options for component selection. The --verbose flag enables detailed logging, helpful for troubleshooting installation issues on non-standard distributions.

Example 3: XFCE Panel Profile Loading

This command applies the pre-configured Windows 95 panel layout:

# Load the Chicago95 panel profile using xfce4-panel-profiles
xfce4-panel-profiles load ~/Chicago95/Extras/Chicago95_Panel_Preset.tar.bz2

# Verify the profile was applied
xfce4-panel-profiles list

# If needed, reset to default
xfce4-panel-profiles reset

Explanation: The xfce4-panel-profiles tool serializes panel configurations into compressed archives. The Chicago95 profile includes panel positioning, plugin arrangement, and size parameters that mimic Windows 95 exactly. Loading this profile instantly reconfigures your desktop without manual tweaking.

Example 4: Plymouth Boot Theme Installation

These commands install the authentic Windows 95 boot splash:

# Copy theme files to Plymouth system directory (requires sudo)
sudo cp -r ~/Chicago95/Plymouth/Chicago95 /usr/share/plymouth/themes/

# Register the theme with update-alternatives system
sudo update-alternatives --install \
  /usr/share/plymouth/themes/default.plymouth \
  default.plymouth \
  /usr/share/plymouth/themes/Chicago95/Chicago95.plymouth \
  100

# Select Chicago95 as active theme
sudo update-alternatives --config default.plymouth
# You'll see a menu - type the number corresponding to Chicago95

# Regenerate initramfs to embed the theme
sudo update-initramfs -u -k all

Explanation: The update-alternatives system manages multiple theme versions on Debian-based distributions. The priority value 100 ensures Chicago95 appears as a selectable option. The final update-initramfs command rebuilds your boot image, making the theme active during system startup.

Example 5: Manual Theme Application Commands

For advanced users who prefer manual control:

# Copy GTK theme to user directory (user-wide installation)
cp -r ~/Chicago95/Theme/Chicago95 ~/.themes/

# Copy icon theme to user directory
cp -r ~/Chicago95/Icons/Chicago95 ~/.icons/

# Set GTK theme via command line
xfconf-query -c xsettings -p /Net/ThemeName -s "Chicago95"

# Set icon theme via command line
xfconf-query -c xsettings -p /Net/IconThemeName -s "Chicago95"

# Apply changes immediately
xfce4-panel -r && xfwm4 --replace

Explanation: These commands bypass the installer for granular control. xfconf-query directly modifies XFCE's configuration database, allowing scripting and automation. The final line restarts the panel and window manager, applying changes without logging out.

Advanced Usage & Best Practices

Creating Custom Plus! Themes

Leverage the Chicago95 Plus! engine to convert vintage themes:

# Navigate to the Plus! directory
cd ~/Chicago95/Plus

# Run the theme converter
python3 Chicago95_plus.py --convert /path/to/your/theme.theme

# Install the converted theme
python3 Chicago95_plus.py --install converted_theme

Pro Tip: Extract themes from Windows 95 ISOs using 7z to access original .theme files.

HiDPI Optimization

For 4K displays, create a custom gtk.css override:

# Create override file
mkdir -p ~/.config/gtk-3.0
echo "@import 'Chicago95/gtk-3.0/gtk.css';
* {
  -GtkWidget-window-scaling-factor: 2;
}" > ~/.config/gtk-3.0/gtk.css

Hybrid Modern/Retro Setup

Combine Chicago95 with contemporary tools:

• Use Chicago95 for system UI
• Keep modern browser with custom CSS
• Employ Alacritty terminal with MS-DOS color scheme
• Run Docker containers for development

This creates a productive environment that looks vintage but performs like 2024.

Performance Optimization
