If you have some special hardware in your computer/laptop which doesn’t behave correctly with free-as-freedom drivers you might experience problems like:

• Not getting a graphical desktop but a blank screen.
• Getting unusable video resolutions.
• Wifi not working.

In that case you might want to download a non-free version of Rescatux.

There is not such a thing but some instructions on how to run Rescapp on top of non-free Debian live images.

Please use this option as a last resort. By using these methods you are putting your freedom as a computer user at stake.
