by 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 2.6.15.6 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
2.6.15.6 (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/2.6.15.6/kernel/drivers/acpi,
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 What should I do to troubleshoot alsa, as I have no sound at all now.
