FAQ

Q: I'm having problems with suspend/hibernate on my laptop. What can i do?

A: We're currently looking into makeing this more realiable for a larger range of laptops. Also we hope to provide a test tool soon with which you can run some tests on your laptop to figure out how to do proper suspend/hibernate on your specific machine.

Q: I have a laptop with Dritek hotkeys, how can i make them work?

A: For several laptops who use those there is a package available here which might help: http://www.haxxed.com/code/dritek-tool-0.1.tar.bz2
