View Full Version : [ubuntu] Sony Vaio VGN-Z21WN brightness problem

November 24th, 2008, 04:57 PM
Hi all,

I recently installed ubuntu 8.10 intrepid on my new sony VGN-Z21WN laptop. All is working perfectly (sound, webcam, most fn keys....)

The only problem : it is impossible to change brightness, it is always at maximum. It is really painful for eyes in darkness and it is using a lot battery.

- fn-F5 and fn-F6 not working (brightness - and +)

- the gnome-brightness-applet is not working (I move the cursor and brightness is not changing)

(also fn-F7 is not working : changing vga output)

Any solution is welcome.
Thank you
