I have aSony Vaio VGN-N130G.
When I try to use brigth control with keyboard
(Fn-F3 less, Fn-F4 more brigth) the keyboard
freezes and the mouse is no longer responding
to clicks. It moves, but the buttons do not work.

If I try Ctrl-Alt-Del, it works, but the keyboard
is still frozen and I have to re-boot.

I do not know if I have to load a new driver.

Any help, is wellcome.

Sonny.
