Sony VAIO FZ brightness WORKS!

[mosquetero]

Hi everyone!

Today I changed from Ubuntu 8.04 to Ubuntu 9.04 but I didn't upgrade, I deleted Ubuntu 8.04 and I installed 9.04 in its place (I had my reasons). This "trick" used to work in the 8.04 version but in the new one it does not work.
Everything goes fine but when I write /usr/local/bin/nvclock -S -10 it says: Xlib: extension "NV-CONTROL" missing on display ":0.0".

Any idea about how to solve it??

I'm trying to install it nvclock on xubuntu. Everything went well untill the ./configure part, where the terminal gives me the following error:
checking for gtk+-2.0 >= 2.4.0... checking for x11... configure: error: "X11 required for nvcontrol support"
So I checked, but X11 is installed, anyone know what I need to do? Maybe I miss a X11 package? Thanks in advance.

I have a VGN AR630e with 9.10 and adding the scripts worked for me.

Following http://www.uluga.ubuntuforums.org/sh...7&postcount=14 and http://www.uluga.ubuntuforums.org/sh...7&postcount=15 worked on a Sony Vaio VGN-SZ1XP with kubuntu 9.10, I just had to

sudo apt-get install nvclock

and create the files under /etc/acpi as mentioned,
slightly modifying the ACPI events to fit to the VGN-SZ1XP - using acpi_listen and noting the events for keypresses and power cable removal/re-plug.
Now increasing/decreasing display brightness works, and display is dimmed automatically if power is plugged off and set to bright once power is plugged in again.

The only (minor) issue left is that the display brightness is always reported as being "0%" in all cases, but display brightness changes properly.

Thanks folks for posting these tweaks!

Just like klaush said: Thanks for this post! I have an updated Mint 10 Linux and Brightness control via fn now works with my vaio VGN-FW31M !

Thanks for all the great work on this tutorial. The commands /usr/local/bin/nvclock -S -10 and /usr/local/bin/nvclock -S +10 are working for me, but what isn't working is the key combinations. My laptop is a FZ11L and the brightness keys are Fn+F5 and Fn+F6 but when I run acpi_listen and press them I get

sony/hotkey SNC 00000001 00000010

sony/hotkey SNC 00000001 0000003b


sony/hotkey SNC 00000001 00000011

sony/hotkey SNC 00000001 0000003b


Can someone show me how to correctly input these into /etc/acpi/events/sony-brightness-down and /etc/acpi/events/sony-brightness-up?

Thanks

I have Sony Vaio VGN FZ340E and after long search I found the solution in the following link

http://doube.org/karmic-vaio

and now its working perfect without any problem I've only changed the (the SPIC to SNC) for both files

sony-brightness-up
sony-brightness-down
Shown expression


for sony-brightness-up file
event=sony/hotkey SPIC 00000001 00000011

I used the following expression
event=sony/hotkey SNC 00000001 00000011

for sony-brightness-down file
event=sony/hotkey SPIC 00000001 00000010

I used the following expression
event=sony/hotkey SNC 00000001 00000010


Backlight

Backlight support for Vaios is now incorporated in nvclock
Make sure you have nvclock installed for basic backlight control, and until HAL has been updated you have to specify the hotkey event manually.

$ sudo apt-get install nvclock
$ nvclock -S 100
$ nvclock -S 15
$ nvclock -S +10

Enable the "brighter" hotkey:

$ sudo gedit /etc/acpi/events/sony-brightness-up
put this text into it:

event=sony/hotkey SNC 00000001 00000011
action=/usr/bin/nvclock -S +10
And the "dimmer" hotkey:

$ sudo gedit /etc/acpi/events/sony-brightness-down
put this text into it:

event=sony/hotkey SNC 00000001 00000010
action=/usr/bin/nvclock -S -10
Make the scripts executable

$ sudo chmod +x /etc/acpi/events/sony-brightness-*
Restart acpid

$ sudo /etc/init.d/acpid restart
If you have a different model, you might have different keys controlling your backlight. To check the event ID, run

$ acpi_listen

I forgot to say that I am using Ubuntu 11.10
