About Debian

The Debian Linux distribution is based on the free software premise. It includes over 15490 packages of precompiled software and gathers a huge community of volunteers and users that keep it up-to-date. You can download Debian here.
A unique feature in Debian is that it evolves continuously over stable releases. New stable releases of Debian are made available from time to time, but users who already have Debian simply update their system using the apt-get (console) or synaptic (graphical) tools.
The Debian is divided into three releases: stable, testing and unstable. The stable version is primarily recommended for serious production and working, since it contains throughly tested software, although not the most recent for obvious reasons.The testing is an almost stable version, with recent software that runs almost flawlessly.The unstable is for developers and wild users who like to live on the edge of software novelties.
The system was installed using the Official Business Card for stable version. Important packages are mentioned whenever needed.

System Configuration

Linux Kernel 2.6.15.
Using KDE desktop environment:
- Install synaptic package for graphical package management.
- Install kdm package for first instance desktop manager.
- Install kdebase package for KDE graphical desktop.
Using the Debian testing release.
CPU frequency scaling is automatically set according to power source (battery/charger).
Battery lasts for about 3 hours.

Setup Details

Hibernate/Suspend to RAM

Install acpid , powersaved and hibernate packages.
Install kpowersave package for KDE graphical power management.
Assuming that the swap is in /dev/hdax, where x is the partition number, add 'resume=/dev/hdax' to the /boot/grub/menu.lst file in the 'kernel' line under the Debian titled entry. Example:

title Debian GNU/Linux, kernel 2.6.15-1-686
kernel /boot/vmlinuz-2.6.15-1-686 root=/dev/hda7 ro resume=/dev/hda6 ec_burst=1
In /etc/powersave/sleep add the ehci_hcd and usbhid modules name to the UNLOAD_MODULES_BEFORE_SUSPEND2DISK, UNLOAD_MODULES_BEFORE_SUSPEND2RAM, UNLOAD_MODULES_BEFORE_STANDBY options, right after the uhci_hcd entry.
In the same file, change SUSPEND2DISK_SHUTDOWN_MODE="shutdown".
To change CPU, Suspend to Disk, Suspend to RAM, etc. settings simply use the kpowersave utility.
If you need to be really sure that these settings apply, restart the system.

Hotkeys

The following hotkeys work
- Suspend
- Brightness Up/Down
- LCD on/off
- LCD/CRT switch display
- NumLock, ScrollLock
Other hotkeys are reported to work if configured with asus_acpi module, already included in the kernel. For more details, see here and here or go to /etc/powersave/sleep and read about the EVENT_OTHER option.

Modem

Install hsfmodem driver from Linuxant to handle the modem's Conexant chip.
The snd_intel8x0m module is overridden by the hsfmodem modules (good).
Note: the hsfmodem is commercial. The free version limits the bandwidth to 14.4k, while the unlimited version costs 20U$ and allows for full speed.

To hear the dial sound, load the hsfdcp daemon by running /usr/sbin/hsfdcpd & as root before dialing. This is required only once per boot.
Use wvdial or kppp programs to connect to the internet.
A good tool to diagnose the modem is found at LinModems, scanmodem. Read the generated ModemData.txt file in Modem directory for a comprehensive and tutorial report on your modem.

Wireless

Unencrypted connections works out of the box. Try running ifconfig eth1 up.

For encrypted connections, the ipw2200 module should be loaded with the option hwcrypto=0 . To automatically load the module with that option, add

options ipw2200 hwcrypto=0
to the file /etc/modutils/ipw2200 file. Run update-modules as root, and restart the module (rmmod ipw2200, modprobe ipw2200) or, if needed, restart the system.
Use the wpasupplicant package. Edit the /etc/network/interfaces and /etc/wpa_supplicant files according to your user data.
When calling wpa_supplicant, use the generic Linux driver, not the ipw driver.
An example for starting an encrypted connection

iwconfig eth1 essid "connection_name" enc open
wpa_supplicant -w -D wext -i eth1 -c /etc/wpa_supplicant.conf
ifup eth1
If required, get the ipw drivers from ipw2000 sourceforge project and extract them to /usr/local/lib/firmware.
