I own an Asus UX32VD. I managed to install 12.10 without any problems following the advices on this page. Everything worked as expected, even many of the Fn keys, excluding F5 and F6.
The problem came after upgrading the kernel to 3.5.0-19 and onwards (as suggested by ubuntu update manager) that WMI stopped to work. When executing lsmod I can see far less modules loaded than when I boot with a working kernel and loading those modules by hand does not work. Actually every fn key behaves as if I was pressing fn+f4 (this after loading the modules by hand).
Is there anything I can do to make this work? Shouldn't I be using 12.10 with this hardware?
Right now the solution I have is to manually boot with kernel 3.5.0-18 that seems to work flawlessly.
