Samsung N 150

Installing Debian Squeeze (still testing at the time of writing) is very comfortably as almost everything works out of the box.

Installation

Prepare the USB stick as described in other installation guides. 

[*] Graphical desktop environment
[*] Laptop Computer

Rest of the installation is pretty straight forward.

Configure hardware itches

Good thing is, it works almost all out of the box

Brightness & Fn-keys

Brightness not working out of the box.

To get brightness work (tested on Wheezy) :

1/ Modify Grub configuration : in /etc/default/grub, add acpi_backlight=vendor to GRUB_CMDLINE_LINUX_DEFAULT. eg. : 

GRUB_CMDLINE_LINUX_DEFAULT="nosplash acpi_backlight=vendor"

2/ Update grub 

update-grub

Some Fn-keys working :

Make them all working installing easy-slow-down-manager package and compiling samsung-tools : 

# aptitude install linux-headers-`uname -r`
# dpkg -i easy-slow-down-manager-dkms_x.x.x_all.deb
# aptitude install xbindkeys dbus-python rfkill gettext
# tar xzf samsung-tools-x.x.x.tar.gz
# cd  samsung-tools-x.x.x
# make
# make install

Then restart the system.

Network

LAN and WLAN working without problems, WLAN during installation without WPA2, though.

CPU scaling

working out of the box

card reader

not tested

Suspension and hibernation

Working with e.g. gnome-power-manager out of the box.

powered USB (usb slot on the left)

not tested

external VGA

Works, although I didn't test the associated Fn key, but with grandr.

Touchpad

To enable tapping, put 

options psmouse proto=imps

Sources

Unconfirmed

most annoing bug: shutdown & reboot not work very well, first time they promt to GDM. To work I must logout session and shutdown or restart.
