Q My laptop has Intel and Nvidia video adaptors. I understand something called Bumblebee can extend the battery life, by letting me disable the Nvidia adaptor. How can I install it in Ubuntu 12.04?
A (Thanks to rodpott in the Ubuntu Forums) Open a terminal and enter these commands:
sudo apt-add-repository ppa:bumblebee/stable
sudo apt-get update
sudo apt-get install bumblebee bumblebee-nvidia
sudo usermod -a -G bumblebee USERNAME
(where you enter the username you log on with.) You can confirm that it's installed by running:
optirun glxspheres
To use the Nvidia adapter with a specific program, precede the program name with “optirun.” For example, “optirun vlc” for the VLC media player.
Q : Mon ordinateur portable possède deux cartes graphiques Intel et Nvidia. J’ai compris que quelque chose appelé Bumblebee peut augmenter la durée de vie de ma batterie en me permettant de désactiver la carte Nvidia. Comment l’installer sous Ubuntu 12.04 ?
R : (Merci à rodpott du Forum Ubuntu) Ouvrez un terminal et saisissez les commandes suivantes :
sudo apt-add-repository ppa:bumblebee/stable
sudo apt-get update
sudo apt-get install bumblebee bumblebee-nvidia
sudo usermod -a -G bumblebee USERNAME (Où vous remplacez USERNAME par votre nom d’utilisateur.). Vous pouvez confirmer qu’il s’est bien installé en lançant :
optirun glxspheres
Pour utiliser la carte Nvidia avec certain programmes, faites précéder le nom du programme par « optirun ». Par exemple, « optirun vlc » pour VLC media player.

A Try ntop.
Q : Quel outil puis-je utiliser pour surveiller les ordinateurs de mon réseau ?

R : Lancez NVIDIA X Server Settings (NdT : paramètres du serveur X NVIDIA), et allez dans la configuration de l’affichage du serveur X.
Q I restarted Xubuntu 11.10 and Conky, that was always on the right side, now has moved to the left side.
A (Thanks to wojox in the Ubuntu Forums) Change:
own_window no
to: own_window yes
Q : Apres avoir redémarré Xubuntu 11.10, Conky, qui a toujours été du coté droit, est à présent à gauche.
R : (Merci à wojox du forum Ubuntu) Remplacez
Own_windo no par own_window yes
Q I have Ubuntu 11.10 desktop edition set up as a server. I want to run it “headless,” no screen, mouse, or keyboard. When I try to control it using VNC, the resolution is too low.
A (Thanks to Cancelor in the Ubuntu Forums) See this message thread: http://ubuntuforums.org/showthread.php?t=1929145
Q : J’utilise un Ubuntu 11.10 desktop edition comme un serveur. Je voudrai l’utiliser sans écran, souris, ni clavier. Lorsque j’en prends le contrôle via VNC, la résolution est trop faible.

R : Abonnez-vous à la Newsletter hebdomadaire d’Ubuntu : https://lists.ubuntu.com/mailman/listinfo/ubuntu-news
Q How can I save directly to a network drive from within an application?
A You just need to do this once: make sure your file manager is set to display hidden files. In your Home folder, scroll down to .gvfs, and right-click on it. Select “Make Link.” The Link will not be hidden, drag it onto your desktop.
After making sure the network drive is mounted, from your application's save dialogue navigate to Desktop, select “Link to .gvfs” and the network drive will appear in it. One more double-click and you can save.
Q : Comment puis-je enregistrer, à partir d’une application, un fichier sur un lecteur réseau ?
R : Vous devez faire ceci une fois : Assurez-vous que votre gestionnaire de fichier est configuré pour afficher les fichiers cachés. Dans votre dossier Home, faites un clic droit sur .gvfs et sélectionnez « créer un lien ». Ce lien ne sera pas caché, glissez le sur votre bureau.
Apres vous être assuré que le lecteur réseau était bien monté, depuis la fenêtre d’enregistrement de fichiers de votre application, naviguez jusqu'à votre bureau, sélectionnez « lien vers .gvfs », vous y trouverez le lecteur réseau. Encore un double clic et vous pouvez enregistrer.
Q I'm building a new computer, but I'm keeping the hard drives that I have now. Do I need to reinstall Ubuntu?
A (Thanks to QIII in the Ubuntu Forums) Disable/remove all third party drivers prior to shutting down for the last time. Backup everything. It is a persistent myth that this “just works”. I have had it work most of the time, but I have also had it fail.
Q I just built a home theatre PC (HTPC) with an Intel Atom 330 (1.6GHz, dual-core) and NVIDIA ION graphics processor. I believed that this machine should play 1080p no problem, but it lags on even 720p, and I get tearing with regular xvid playback.
A (Thanks to Michael37 in the Ubuntu Forums) Try xbmc. I have an Acer Aspire Revo 3600 (dual-core Atom 330 and Nvidia Ion). I don't have any problems playing 1080p content. I am using the v190 driver and VDPAU acceleration. http://wiki.xbmc.org/index.php?title=Installing_XBMC_for_Linux
Two Tips and Techniques Day and Night
I'm currently evaluating what version or distro of Linux I will move to this spring. Even to me, my parameters are amusing. Here is perhaps the most unusual.
In Ubuntu 10.10, I have been using an applet called f.lux, and I like it a lot. It's not very exciting: at dusk, it reduces the brightness of my display, and makes it warmer. At dawn, it brightens my screen, and makes it cooler. No big deal, but it enhances my computer usage.
Of course, determining “dusk” and “dawn” requires knowing my latitude and longitude. Fortunately, Google Maps give me that information.
Sharing Simplified
On average, I try one new version or distro of Linux a month. One of the features I always try, is to set up a shared folder, and to access shared folders on other computers. It always works, so I don't understand why people have trouble with this feature.
To create a shared folder on any distro which uses Nautilus as its file manager, I create a folder called “shared”. In Nautilus, I right-click and select “sharing options.” I click on “Share this folder,” “Allow others to create and delete files in this folder”, and “Guest access.” Then I click on “Create Share.” All done.
Depending on the distro, I am prompted to install Samba, then start again.
To access shared folders on other computers, I start the file manager. I select, “Browse Network.” I double-click on a computer name, then on a shared folder. At this point, I can copy or paste files. It all “just works.”
In Kubuntu, with the Dolphin file manager, I take the same steps, although the details are slightly different.
My wife is Chinese, so she requires the QQ video-conferencing software – which works only under Windows. When I connect to her Windows 7 Ultimate computer, I am prompted to enter a Windows username and password. No problem.
In the past three years, I have never edited a configuration file. I have never used the Terminal for anything to do with folder sharing. It has always “Just Worked.” If your experience is different, and you know why, I would like to hear from you.
