FC4@Sony Vaio VGN-FE11S

FC4@Sony Vaio VGN-FE11S

Post by ndro » Wed, 15 Mar 2006 02:47:10

Hi everybody, I just recently purchased a Sony Vaio VGN-FE11S with
following configuration

CPU: Intel Core Duo T2400 1.83 GHz
Chipset: Intel 945
RAM: 1GB DDR2 533 MHz
Graphics adaptor: Nvidia GeForce Go 7400 256 MB RAM
Hard disk: 160GB SATA 4200 RPM
Wlan: Intel Pro Wireless 3945 802.11a/b/g

I have been trying to install FC4 on the laptop, as I had already
successfully done it in a Sony Vaio VGN-FS215S, but this time I am
encountering insurmountable obstacles :-( More specifically, I have
compiled kernel myself, and am still unable to get the video
card, the lcd brightness control and the sound to work. I am stating a
few things about each of these, all comments will really be appreciated:

1) Nvidia GeForce Go 7400

I know it's not yet (?) officially supported, I' ve looked everywhere for
workarounds, but thought i might ask as a last hope, anyway: What would
be a decent X configuration for the GeForce Go 7 series (personally,
I have the 7400 model), in terms of driver and xorg.conf options? I
've tried nvidia v.8178 (doesn't work, of course), nv driver of kernel (delivers decent 2D, but crashes after a while) and generic vesa
(seems to be stable, but the result is awful).

2) LCD brightness control

I have downloaded and installed sony_acpi from
http://www.gagme.com/greg/linux/sony_acpi-0.3.tar.gz, the module has
been installed successfully in /lib/modules/,
it modprobe's ok, directory /proc/acpi/sony/ contains brightness and
brightness_default, as anticipated, but whenever I write a value to
brightness through

echo 1 > /proc/acpi/sony/brightness

nothing happens :-( The value is written, no error dmesg output, but
still, no change in brightness.

3) Sound

I haven't looked that trough quite thoroughly, I am not the alsa expert,
but thought I might ask. I included Intel HD audio support in the kernel,
and following modules have been loaded

# lsmod | grep -i snd  
snd_hda_intel          22672  0
snd_hda_codec          93056  1 snd_hda_intel
snd_seq_dummy           8068  0
snd_seq_oss            39296  0
snd_seq_midi_event     11648  1 snd_seq_oss
snd_seq                59280  5 snd_seq_dummy,snd_seq_oss,snd_seq_midi_event
snd_seq_device         13452  3 snd_seq_dummy,snd_seq_oss,snd_seq
snd_pcm_oss            58272  0
snd_mixer_oss          23424  1 snd_pcm_oss
snd_pcm                97540  3 snd_hda_intel,snd_hda_codec,snd_pcm_oss
snd_timer              30340  2 snd_seq,snd_pcm
snd                    62308  9 snd_hda_intel,snd_hda_codec,snd_seq_oss,snd_seq,snd_seq_device,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer
soundcore              14432  1 snd
snd_page_alloc         15368  2 snd_hda_intel,snd_pcm

What should I do to troubleshoot alsa, as I have no sound at all now.

if anyone has had any luck running linux on one of the new
sony vaio a-series notebooks, such as the VGN-A190,
please let me know.

I'm thinking very seriously about purchasing one,
but they are quite expensive, and I couldn't not find anything
posted anywhere from anyone who has run linux on one of them.

I already checked: http://www.linux-on-laptops.com/sony.html
