💡 Troubleshooting & FAQ

Q: I see a grey square, is it broken?

A: No! The grey square means the VM is loading. DSL Linux is ~700MB, so initial loading may take 1-5 minutes depending on your connection.

Q: The VM seems stuck or frozen?

A: Wait a few minutes for the boot process to complete. If still stuck, try refreshing the page and starting again.

Q: How do I interact with the VM?

A: Click inside the VM screen to capture your mouse and keyboard. Press ESC to exit fullscreen mode.

Q: Performance issues?

A: Close other browser tabs and applications. The VM requires significant system resources to run smoothly.

Q: What are the VM specifications?

A: MiniVM runs with 2GB RAM, 32MB video memory, and enhanced CPU compatibility. This provides excellent performance for web browsing, code testing, and running development tools like Firefox and text editors.

Q: Can I browse the web and test code?

A: Yes! With 2GB RAM and network support, you can run Firefox for web browsing, use development tools, test HTML5/WebAssembly applications, and even play simple web games. The VM supports modern web standards through the included browser.

Q: Firefox is using 100% CPU - how can I improve performance?

A: Firefox is very heavy for browser-based emulation. Try these tips: 1) Close other browser tabs on your host system, 2) Use lighter browsers like Dillo or Links instead, 3) Disable Firefox animations and reduce tabs, 4) Use Chrome/Edge for better WebAssembly performance, 5) Consider using text-based browsers for development testing.

Q: What are lighter alternatives to Firefox?

A: DSL Linux includes several lighter browsers: Dillo (graphical, fast), Links (text/graphical), Lynx (text-only). For code testing, use simple HTTP servers and curl/wget commands. These alternatives use much less CPU while still allowing web development testing.

Q: How can I optimize my host system for better VM performance?

A: Browser: Use Chrome/Edge for best WebAssembly performance. Enable hardware acceleration in browser settings. System: Close unnecessary applications and browser tabs. Advanced: Add these Chrome flags: --enable-webassembly-baseline --enable-webassembly-lazy-compilation for better performance.

Q: How can I use more of my CPU power for the VM?

A: Chrome flags: Launch with --high-dpi-support=1 --force-gpu-rasterization --enable-zero-copy --enable-webassembly-threads
System: Set browser process priority to "High" in Task Manager
Advanced: Use dedicated browser profile with: chrome --user-data-dir=/tmp/vm-browser --no-sandbox --disable-web-security
Note: VM is limited to single-core emulation, but these optimizations maximize that core's efficiency.

Q: Login credentials?

A: Username: dsl (no password required). You'll boot directly to the desktop.

Q: Can I use my own ISO file?

A: Yes! Select "Local ISO File" above and upload your own DSL Linux ISO. This provides faster loading and allows you to use customized versions.

⚠️ This is just a proof of concept and may not work on all devices or browsers.
