Comment 72 for bug 661248

I don't know what are the differences between Sabayon and Ubuntu kernels, but it works. Maybe installing Sabayon kernel in ubuntu will change something or maybe this is more complex problem. Anyway I can confirm that it works on kenel 2.6.39-sabayon, xorg-server-1.10.3, nvidia-drivers-280.13 packages from official sabayon repository. Sabayon6 x64. Oh and my hardware is Compal FL90 (Nvidia 8600M GT).
