Thanks but I tried nvclock already. Even the latest CVS version says
it doesn´t support the hardware, unfortunately...
If someone has a solution for the Z13 I'd love to hear about it...
Thanks

You should be able to use nvclock to change brightness. The
following is what I use, but I don't ever use the Intel card, so
to make it generic, you'd want to do some sort of detection in the
shell script, depending on how you're doing your switching.
# /etc/acpi/events/sony-z-brightness-down
event=sony/hotkey SNC 00000001 00000010
action=/etc/acpi/sonyzbrightbtn.sh down

Hi Jordi,
Same here, I would be very happy if we could control brightness
while running on the NVIDIA card. I don't know exactly what it
takes, maybe the Intel card needs to be accessible from the PCI
bus (since, as I heard, the physical brightless control is
connected to the Intel card). As I see it, initializing the
Intel card without allocating any of its buffers (ie: initialize
it just enough so we can ask it to set the brightness) might be
the way to do it.
Maybe we could set up a bounty that would go to the one who
publishes a kernel patch and/or generic shell script and
instructions to do it ? That could be nice...

Hi,
I'm a new Vaio Z user, and I've successfully installed Linux
as Main OS on a VPCZ11X9/e, after some struggling I've gotten
everything working, including hsdpa and graphics switching.
My only gripe so far is the inability to control screen
brightness when using nvidia graphics.
Any updates on this issue? what changes will be necessary to
implement it?
