Configuring

Well, when you install the Ubuntu "Hoary Hedgedog" (5.04) almost everithing is automatically configured, except :

Atheros

To be honest, my atheros device only works with 2.6.12-8-386 kernel. For this, i do:

# apt-get install linux-image-2.6.12-8-386 linux-restricted-modules-2.6.12-8-386 

then, try to:

# modprobe ath_pci 

if you get a message of "invalid module format" don't be panic, just:

# apt-get install modutils

so, repeat the modprobe steb, and be hapy =)

Suspend to RAM

This is the hardest configuration of the notebook Just uncomment the line (its the second one) above on file /etc/default/acpi-support

ACPI_SLEEP=true

TouchPad ScrollBar

Touchpad scrollbar, is a "virtual" scrollbar on the touchpad. With this feature enabled, when you move up or down at right side of the touchpad, the mouse scrolls like a wheel. Just add this lines to your /etc/X11/xorg.conf on the InputDevice section

...
        Option      "Emulate3Buttons" "yes"
        Option      "LeftEdge" "120"
        Option      "RightEdge" "830"
        Option      "TopEdge" "120"
        Option      "BottomEdge" "650"
        Option      "FingerLow" "14"
        Option      "FingerHigh" "15"
        Option      "MaxTapMove" "110"
        Option      "VertScrollDelta" "20"
        Option      "HorizScrollDelta" "20"
        Option      "MinSpeed" "0.3"
        Option      "MaxSpeed" "0.75"

Backlight ScreenSaver

This is the most hacked feature of the howto. Unless Satellite be a Toshiba laptop, the kernel doesn't recognize it as a Toshiba laptop. Funny ham? So, we use the module of HP Omnibook (http://sourceforge.net/projects/omke) that works almost perfectly. I have developed a script that runs at top of xscreensaver. This script can turn off the backlight as soon as the screen goes blank. It still in developing, so, bugs will appear. This is the script:

use strict;

open PORTS, "+</dev/port" or die("can't open /dev/port");

open(XS,"/usr/bin/xscreensaver-command -watch|") or die;

while(<XS>) {
    if(/^BLANK/i) {
        kbd_param(0xE2) if (kbd_command(0x59));
    }
    if(/^UNBLANK/i) {
        kbd_param(0xE1) if (kbd_command(0x59)); # liga
    }
}
close XS;
close PORTS;

########### this is the functions that i got from the omke script
########### http://sourceforge.net/projects/omke
sub inb {
        my ($port, $data) = (shift, undef);
        sysseek PORTS, $port, 0;
        sysread PORTS, $data, 1;
        return ord($data);
}

sub outb {
        my ($data, $port) = (shift, shift);
        sysseek PORTS, $port, 0;
        syswrite PORTS, chr($data);
}
sub wait_kbd_empty {
        my $i = 5000;
        while((inb(0x64) & 2) and $i) {
                $i--;
                if ($i == 0) {
                        print "timeout waiting for the buffer to empty\n";
                        return 0;
                }
        }
        return 1;
}

sub kbd_command {
        my $command = shift;
        if (wait_kbd_empty()) {
                outb($command, 0x64);
                return 1;
        }
        return 0;
}
sub kbd_param {
        my $param = shift;
        if (wait_kbd_empty()) {
                outb($param, 0x60);
                return 1;
        }
        return 0;
}
############# end of script

To use this, run AS ROOT as daemon, like this:

 $ sudo perl backoff.pl &

then, just wait until the screensaver goes blank, and the backlight should off.

Tip : I just have put the backoff.pl at '/usr/bin' and declared on the '/etc/sudoers' with NOPASSWD attribute. Then, I start the script on the gnome startup, and work perfectly.

Special Keys

These are the keys on left side of keyboard. To make them works, just make sure you have HP Omnibook (http://sourceforge.net/projects/omke) module loaded on ur kernel and just :

  apt-get install hotkeys

edit the file  /usr/share/hotkeys/toshiba.def  and put this piece of code on that:

<?xml version="1.0"?>

<definition>

  <config model="Toshiba M35x-S311 Laptop">
 
    <PrevTrack    keycode="144"/>
    <Play         keycode="162"/>
    <Stop         keycode="164"/>
    <NextTrack    keycode="153"/>
   
    <userdef keycode="237" command="beep-media-player"> Beep Media Player </userdef>

  </config>

</definition>

thanks for Kyle Dickerson

Then to make it work, you can edit the file  /etc/hotkeys.conf  and setup it properly. The file is well commented, but here's mine as well:

Kbd=toshiba
PrevTrack=beep-media-player --rew
Play=beep-media-player --play-pause
Stop=beep-media-player --stop
NextTrack=beep-media-player --fwd

ok, no mistakes, juts run:  hotkeys  at GNOME (or other WM/DE) startup!

Have fun! ;_)
