OK You’re right ; I was probably with the intel card when I tried it. On the nvidia side I can confirm it doesn’t work (applet or function keys).

Actually, it’s not so annoying for me : I use the nvidia card when I am on AC power, so saving power is not a real problem.

I just tried your command “sudo acpi_create_nv_event” and it made the fn keys working, though I cannot decrease the brightness a lot. The applet doesn’t work very well either.

Hmm, interesting. On the Intel the brightness indicator seems to work fine but on the Nvidia side it does not seem to change and the applet does not seem to work, and it seems like there are more steps in the brightness (to get to half brightness it takes about twice as many clicks), maybe I will try to uninstall/reinstall the script and drivers from scratch again.

This might help someone reading this, another thing that I noticed is when I would load an ICC profile with xcalib (created in Windows using a Spyder2) the Nvidia X Server Settings would revert it back to the default colors on login/startup, so I just disabled that through the Startup Applications Preferences, I have not noticed any negative effects from disabling this so far.

@Tim Happy if I could help. You are confirming my guess, this line in grub is mandatory.

I didn’t use a hacked bios, I’m using the bios provided by Sony, and upgraded it to the last version using their utility in windows. I haven’t experimented any direct install.

For the brightness issue, I can’t help you further, my fn+F5 or Fn+F6 did the trick, at least after the installation of the janitor script (maybe before, I can’t remember). The brightness applet (in panel) is working fine too.

Nevermind, it just started working, after reinstalling the drivers about 10 times I realized (thanks to your post) that I forgot to add:

GRUB_CMDLINE_LINUX=”acpi_osi=\\\”!Windows 2006\\\”" to /etc/default/grub

The only problem I had was that I could not change the brightness. This command helped me out though:

sudo acpi_create_nv_event

The only problem now is the brightness indicator in Ubuntu does not show what brightness you are at which is no big deal, at least I can change the brightness now.

So, did you end up using a hacked (Advanced options) bios or were you able to get it to work without it?

I’m having trouble getting the Nvidia side working, the Intel seems to work fine but every time i start with the switch on SPEED it just reverts back to the Intel gpu.

I am using the latest official version of the bios with a VGN-Z610Y, dual-booting 10.04 and Win7.

We bought it for our meeting room at AppliBox (http://www.appli-box.com/), and we are very happy with it. We ordered a pretty black metal frame in a local store (more expensive than the poster indeed), and the effect is perfect !
