[ubuntu] AR series Sony VAIO & Hardy > unresolved problems

[devill]

As I have not managed to find a thread for AR series VAIO users I decided to open one, and sum up my experiences.

I have Sony VAIO VGN-AR550U laptop, and Hardy Heron installed about 2 weeks ago...

Most of the things are working fine right out of the box, except for:

* Sound card needed a fix (see solution below)
* WebCam is not recognized, nor did it appear in lspci or lsusb
* FN keys won't work except for volume controls
* I did not manage to change back light settings, not even with xbacklight (returns: No outputs have backlight property)

If any one could help me on the remaining problems, it would be appreciated!

Soundcard fix:

sudo gedit /etc/modprobe.d/alsa-base

and add the lines below to the end

options snd-hda-intel model=vaio
options snd-hda-intel model=3stack probe_mask=1

Reboot, and hope for the best

Try running these commands in the terminal:

xrandr --output LVDS --set BACKLIGHT_CONTROL native
sudo /etc/init.d/acpid restart

And try xbacklight again.

Nepherte,
I have the same backlight problem than devill, although I have a Sony Vaio SR129E/B, with a Radeon HD 3470 graphic card. (and a amd64 Ubuntu Hardy version)

When I tried xbacklight, I got: "No outputs have backlight property"

I tried then what you said:

xrandr --output LVDS --set BACKLIGHT_CONTROL native

But I got:

a3qp@a3qp-laptop:~$ xrandr --output LVDS --set BACKLIGHT_CONTROL native
X Error of failed request:  173
  Major opcode of failed request:  159 (RANDR)
  Minor opcode of failed request:  15 ()
  Serial number of failed request:  14
  Current serial number in output stream:  14

So I couldn't try the next code instruction you said.

I appreciate any help, since my screen is really dark now.
(not in windows).

Thanks,
