   • Great for temporary use or when installing software isn’t permitted.

Where to download safely

• Prefer official project pages, GitHub repositories, or well-known freeware portals.
• Verify digital signatures/checksums when available.
• Avoid sites that bundle toolbars, adware, or require additional installers.
• Scan installers with an updated antivirus if you’re unsure.

Download and installation — step by step

Windows (Windows ⁄₁₁)

1. Download the installer (EXE or MSI) from the official site or GitHub release.
2. Right-click the installer and select “Run as administrator” if prompted.
3. Follow the setup wizard; opt out of any bundled offers.
4. After installation:
   • Open Settings > Personalization > Lock screen > Screen saver settings.
   • Choose the installed LavaLamp screensaver from the dropdown.
   • Click Settings (if available) to adjust colors, speed, and behavior.
   • Set the wait time and click Apply → OK.

macOS (Ventura, Sonoma, and newer)

1. If a native screensaver (.saver) is provided, download the ZIP or DMG and mount it.
2. Double-click the .saver file. macOS will ask whether to install for the current user or all users.
3. Open System Settings (or System Preferences) > Lock Screen (or Desktop & Screen Saver) > Screen Saver.
4. Select the installed lava lamp screensaver and click “Screen Saver Options” to customize.
5. For apps without native macOS support, consider running through a compatible port or using the browser‑based WebLava.

Linux (GNOME, KDE, Xfce)

1. Prefer packages from your distro’s repository or a trusted GitHub release.
2. For GL-Lava:
   • Download source or prebuilt binary.
   • If building from source, follow README (usually: ./configure, make, sudo make install).
3. Configure screensaver:
   • GNOME: Install and use GNOME Screensaver or set a blank screensaver and run the lava app as a background session.
   • KDE: System Settings > Workspace Behavior > Screen Locking / Screen Saver and pick the installed module.
4. Make sure the appropriate GPU drivers and OpenGL libraries are installed for best performance.

Browser-based (WebLava)

1. Open the WebLava page in your browser.
2. Click full-screen or press F11 to enter a distraction‑free view.
3. Use on any OS without installation.

Customization tips

• Color palettes: Use complementary or monochrome palettes for different moods (cool blues for calm, warm reds for energy).
• Speed & physics: Increase viscosity for slow, sultry motion; decrease for faster, bubbly action.
• Transparency: Lower opacity to blend with your desktop background.
• Multi-monitor: Extend or mirror the effect—check the screensaver’s multi-monitor settings.
• Scheduling: Use OS scheduler or built‑in timing to limit when the screensaver runs (e.g., only after dark).

Performance considerations

• GPU acceleration reduces CPU load — prefer OpenGL/WebGL versions when available.
• On laptops, set the screensaver to pause or disable when on battery if it increases power draw.
• For older machines, choose simpler visual presets or RetroLamp for minimal resource use.

Troubleshooting common issues

• Screensaver not showing: Verify it’s selected in system settings and the wait time is set low enough. On Windows, check Group Policy if managed by IT.
• High CPU usage: Switch to GPU-accelerated version or lower rendering quality.
• Black screen on resume: Update graphics drivers; on Windows, disable “Fast startup” as a test.
• Installer blocked: Right-click → Properties → Unblock, then run as administrator. Scan for malware if downloaded from an unfamiliar source.

Licensing and safety notes

• Many lava lamp screensavers are open-source or freeware. Check the license (MIT, GPL, proprietary) if you plan to redistribute or modify.
• Respect any trademarked artwork and avoid installing from suspicious sites to minimize bundled adware risk.
