I compiled my kernel into a deb package and installed the very same deb package on three machines: MSI p45 neo3 with Hardy on it -> works OK MSI p45 neo3 with Ludid on it -> nothing (works fine with regular kernel) MSI 945P with Lucid on it: -> nothing (works fine with regular kernel) I'll try the suggestions posted and keep you informed.
