now I am working with my Vaio VPCZ12Z9E on Ubuntu oneiric that looks like to me at this point quite stable. But steel doesn't appear vga_switcheroo in sys/kernel/debug and I am meditating to recompile the kernel. Could you help me in this operation (where to find the required kernel 3.0.0 source, the proper patches to bind, a generally indication of the metod) considering that I am an untrained user? Thanks. niky
