    Using Ubuntu as main OS for years now on all Laptop and desk
    top at home, I am regularly in front of common problems. But one of the most anoying is the "backlight off bug",

    Samsung-q210

    Sometimes, after kernel update, my laptop LCD decide to stay off, for unknown reason.

    So only one way to restore it:

    sudo vbetools dpms on

    This is the only solution I have found to restore the "ON" state.

    After any reboot, the LCD stay ON.

    Ubuntu is sometimes frustrating for newbies. So here is ONE solution.

    Connaissez vous le  site www.box.com qui propose du stockage en ligne gratuit à hauteur de 5Go ?

    Si non, courrez vous créer un compte pour stocker tous les fichiers qui vous sont vitaux.

    Donc, un fois votre compte en main, vous allez pouvoir le monter comme un disque local sous linux avec les informations suivantes !

    Tout d'abord,  commençezs par installer l'outil magique qui va permettre d'accèder au repertoire DAV distant sur box.com

      #> sudo apt-get install davfs2

    Maintenant, créez un répertoire box.com dans votre répertoire personnel:

      #> mkdir ~/box.com

    Ensuite, éditez le fichier fstab décrivant les volumes monté au démarrage (vos disques connus de linux):

      #> sudo gedit /etc/fstab

    Et ajouter la ligne ci-dessous:

      https://www.box.com/dav /home/[username]/box.com davfs rw,user,noauto 0 0

    où [username] est votre nom d'utilisateur linux.

    Ensuite, créons l'espace de stockage de nom / password pour le nouveau point de montage DAV.

    Créez un répertoire .davfs2 dans votre $HOME

      #> mkdir  ~/.davfs2
      #> cp /etc/davfs2/davfs2.conf ~/.davfs2
      #> sudo cp /etc/davfs2/secrets ~/.davfs2
      #> sudo chown $USER ~/.davfs2/secrets

    Et éditez le fichier ~/.davfs2/secrets  pour ajouter une ligne de la forme:

      https://www.box.com/dav    [box.username]    [box.password]

    où [box.username] et [box.password] sont respectivement les nom et mot de passe utilisateur de votre compte box.com.

     Maintenant la commande magique:

      #> mount ~/box.com

    Et voila, vous avez accès à vos fichiers présents sur votre compte box.com !

    Pour démonter le lecteur box.com, simple:

      #> umount ~/box.com

    Encore plus fort, sous Nautilus, une nouvelle entrée de volume est disponible, un seul click sur l'icone et le lecteur est monté.  Un click sur le petit bouton de démontage, à droite et le lecteur est démonté.

    Nautilus-drive-box-com
    Note:

    Si comme moi, vous êtes confrontés à l'impossibilité de monter un volume DAVFS en tant que simple utilisateur (non root) vous devez passer la commande suivante:


      #> sudo chmod u+s /sbin/mount.davfs 

     Merci à launchpad https://bugs.launchpad.net/ubuntu/+source/davfs2/+bug/46995

    facile, non ?

    Ubuntu 10.04 bring a lot of interesting features on social side, twitter, facebook, and so on. But...
    The new Look of the gnome interface contains a strange choice about User interface:  The window buttons side !

    Left side for window size and action management is, IMHO, a wrong choice.

    Right side is what human kind is usefull with.

    So to bring back old uses :

    Start gconf-editor, and go to the apps/metacity/general configuration to edit the button_layout key, and set:


    menu:maximize,minimize,close

     
    (full story and guide here: http://www.howtogeek.com/howto/13535/move-window-buttons-back-to-the-right-in-ubuntu-10.04/).

    and get your window with the right side ;)

    RedCar is a brand new programmer's editor ruby oriented, and ruby developed.
    And on of the main feature of this new text editor, it's to be JRuby compatible natively !  A good news for the multiplatform world.

    to be tested to help dev team to improve this cool programmer's tool.

    Is it possible to optimize such editor for Rails and Hobo ?

  • Ubuntu 8.10 on EeePC 900 : easy mode !

    Note:
    First thing to get it working is to be sure you will be able to connect your netbook to ethernet in wire mode.

    ----

    Installation of Ubuntu 8.10 Live on a USB key.

    The best way to do rule this part is to use the famous UnetBootIn. this tool will allow you to install easily your prefered Linux Distro, here we will choose Ubuntu 8.10 live, on a USB key. Please choose a 1Gb sized k

    The best way to do rule this part is to use the famous UnetBootIn. this tool will allow you to install easily your prefered Linux Distro, here we will choose Ubuntu 8.10 live, on a USB key. Please choose a 1Gb sized key to be quiet.

    So just download unetbootin (twin versions exists : a windows and a linux version), and run it. If you are on Linux, you will be asked to install another debian package containing 7z. You will find a page on the official french Ubuntu site, on in the Ubuntu-eee site explaining how to use it.

    EeePC 900: get it work !

    Now the easiest part of this how-to: install Ubuntu 8.10 on your EeePC. Just click on the Install icon the Desk after booting on just prepared before USB Key. To boot on it, push the ESC key and choose the USB Device, while your Eee PC is just switch on and you get the grey screen with the EeePC logo.

    After installing this, connect your Ethernet wire and update your just installed Ubuntu. now you are ready to customize your netbook OS accordingly to the EeePC capacities (Wifi, CPU frequency tools, Energy saving, etc...)

    Wifi

    We will have 2 steps to do:

    1. - remove existing ATH modules
    2. - install backported from Hardy Heron the ath5k module.

    Remove the existing modules:

    sudo modprobe -r ath_pci
    sudo modprobe -r ath_hal

    Add to the balck list these 2 modules:

    edit the file /etc/modprobe.d/blacklist and add the 2 following lines at the end:

    blacklist ath_pci
    blacklist ath_hal

    Connect to the internet through ethernet (get wired !) and backport modules from Hardy Heron:

    sudo apt-get install linux-backports-modules-intrepid-generic

    Now, just reboot, and you will get the wifi running, and will be able to configure your wireless connection via NetworkManager.

    CPU frequency managing

    To activate the cpu frequency selector, you will have to install the following:

    sudo apt-get install gnome-cpufreq-selector

    And now edit /etc/modules and add this line at the end:

    load p4-clockmod

    Energy Saving

    To enable the cpu frequency adaptor following energy mode, you will have to modify registry with gconf-editor.

    dpkg --reconfigure gnome-applets

    powertop will could easily help you reducing energy consumption by analyzing actual energy wasts and give you useful tips on how to save.

    sudo apt-get install powertop

    For more information on the Gnome Power management, see this page.

    And that's all folk !

    to be continued ....

    The other well known mail client in the inu Gnome world id Evolution, the free work suite solution for entreprise.

    The soft is very powerfull and well featured, but a little bit too slow for my poor Celeron M 900MHz on my EeePC 900 !

    Evo-logo3

    So, even if it's the best and well integrated mail client in the gnome desktop, well, I can't use it in battery mode, while the processor economy mode is "on demand" mode.

    Micro blogging, updated sites detection, and fast launching anything on my netbook running Ubuntu eee 8.04.1  is what is now possible thank to the following fabulous tools:

    Gwibber

    It's a webkit based poster for any blog/twitter/facebook platform. Well rendered, the tool use the apple opensourced version of webkit, the HTML renderer. with a userfriendly interface, anybody can now feed its muti sourced blogs and be advertized when a known and wel configured site was updated.

    • install gwibber.

    Specto

    It's an old tool, but nothing replace this llittle thing which permit you tobe informed when a site was updated, giving a little mesage from the gnome panel that the site John Doe was updated.

    • download specto.

    Gnome-Do

    the faster way to start anything on your laptop ! Just push the "super"+"space" combination keys and you'll just have to input some first letters of what you want to do, "facebook" for exemple will open your bookmark from firefox or epiphany to te facebook site, "text" will route you to the "OpenOffice Text writer" and if more than one item respond to your input, a list will appear pressing "down key", and then, just hit the "enter" or "return" key and that's all !

    • install gnome-do

    [edit] Add the --mini parameter to the gnome-do command and you'll get a well netbook feated UI !  great, thanks to Alex for the tips.

    Thanks to opensource software to solve all these every day life problems ;)
