Q I tried to install Ubuntu, and wound up wiping out my Windows system – and all my priceless data. How can I recover? A Stop using the computer immediately! You may be able to recover some of your data, maybe a lot of your data. Remove the hard drive from the computer. If this is your only computer, buy another hard drive, install it, then install Ubuntu. If you don't already own a USB adapter for an external hard drive, buy one, (I've used a couple which cost less than $10.) Install Testdisk and Photorec and read about how to use them. Select the one which seems most likely to be useful. Plug in your old hard drive as an external drive. Run your chosen data recovery package, and see what happens.
Q J'ai essayé d'installer Ubuntu, et ai fini par endommagé au point d'anéantir mon système Windows - et toutes mes données inestimables. Comment puis-je tout récupérer ?
R Arrêtez immédiatement d'utiliser l'ordinateur! Vous pouvez être en mesure de récupérer une partie de vos données, peut-être beaucoup de vos données.
Retirez le disque dur de l'ordinateur. Si ceci est votre seul ordinateur, acheter un autre disque dur, installer le, puis installer Ubuntu. Si vous ne possédez pas déjà un adaptateur USB pour un disque dur externe, acheter un, (j'en ai utilisé une pair qui a coûté moins de 10 $.) Installer Testdisk et PhotoRec et lire sur la façon de les utiliser. Choisissez celle qui semble la plus susceptible d'être utile. Branchez votre ancien disque dur comme un disque dur externe. Exécutez votre paquet de récupération de données choisi, et voir ce qui se passe.
Q Will the Tesseract OCR program be faster than looking at an image and typing the text into a file? A No, you will spend more time correcting Tesseract's output than if you just typed it in from scratch.
Q Est-ce que le programme OCR Tesseract sera plus rapide que le fait de saisir un texte dans un fichier en lisant une image qui le contient ?
R Non, vous passerez plus de temps à corriger la sortie de Tesseract que si vous venez de taper ce texte en partant de zéro.
Q How can I set my keyboard permanently to Portuguese? A (Thanks to papibe in the Ubuntu Forums) Open 'Keyboard Layout', add the Portuguese keyboard by pressing the + symbol, then move it to the top of the list or remove the other layouts.
Q Comment puis-je configurer mon clavier en permanence en Portugais ?
R (Merci à papibe dans les forums Ubuntu) Ouvrir « Keyboard Layout » , ajouter le clavier portugais en appuyant sur le symbole +, puis déplacez-le vers le haut de la liste ou supprimer les autres dispositions.

Q J'ai réalisé les dernières mises à jour sur Xubuntu 12.04 et ai remarqué qu'il ne ma pas été demande mon mot de passe pour m'authentifier ?
R Oui, c'est la nouvelle norme. voir http://goo.gl/DNlIX
Q I modified an important file, and can't boot into the graphical system. When I boot into recovery mode, the filesystem is read-only. How can I fix the file I messed up? A (Thanks to Cheesemill in the Ubuntu Forums) In recovery mode, enter this command, which will let you edit the file: mount -o rw,remount /
Q J'ai modifié un fichier important, et ne peut pas démarrer le système graphique. Lorsque je démarre en mode de récupération, le système de fichiers est en lecture seule. Comment puis-je corriger le fichier que j'ai endommagé ?

mount -o rw,remount /
Q I have the “backports” repository activated in Mint 13, so I get the newest versions of Cinnamon. I understand the Mint team has forked Nautilus, but when I click on File Manager, I still get Nautilus. A Open a terminal and enter this command: nemo If you decide you want to make nemo your default file manager, go to this web page: http://www.fandigital.com/2013/01/set-nemo-default-file-manager-ubuntu.html As well, there is a file manager in the panel, which requires further work. Right-click on it and select “Edit”. Change the Application from nautilus to nemo, click on Update. Also, there is a (nautilus) File Manager on the left side when you click on Menu. Simply drag it into, say Accessories. When you open Accessories, you might see an entry labelled Files, which you can drag to the left side of the Menu. You may want to edit menu entries, install Alacarte, which gets installed as “Main Menu”.
Q J'ai les sources « backports » activées dans Mint 13, donc je peux obtenir les dernières versions de CINNAMON. Je comprends que l'équipe Mint a fait bifurqué Nautilus pour le remplacer par un embranchement, mais quand je clique sur Gestionnaire de fichiers, je lance toujours Nautilus.
R Ouvrez un terminal et entrez la commande : nemo
Si vous décidez que vous voulez faire de nemo votre gestionnaire de fichiers par défaut, allez à la page Web : http://www.fandigital.com/2013/01/set-nemo-default-file-manager-ubuntu.html
En outre, il existe un gestionnaire de fichiers dans le panneau, ce qui nécessite des travaux supplémentaires. Faites un clic droit dessus et sélectionnez « Modifier ». Changer l'application de nautilus à nemo, cliquez sur Mettre à jour.
Aussi, il y a aussi une entrée nautilus du Gestionnaire de fichiers sur le côté gauche lorsque vous cliquez sur Menu. Il suffit de glisser dans, disent accessoires. Lorsque vous ouvrez accessoires, vous pouvez voir une entrée marquée fichiers, que vous pouvez faire glisser sur le côté gauche du menu. Vous pouvez modifier les entrées du menu, installez Alacarte, qui est installé comme « Menu principal ».
Q I bought a USB turntable to convert my vinyl collection to computer files, but it doesn't work very well.
A Just bit-torrent download the tracks you legitimately own. I was capturing my favorite tracks, turntable to amp to line-in to Audacity. My son challenged me: “can you capture a track faster than I can bit-torrent it?” It wasn't close.
If you own a vinyl record, it is completely legal for you to download an MP3 of that record; it's called “backup.” Mind you, I am not a lawyer, so I can't provide legal advice. My guru on copyright is Brad Templeton: http://www.templetons.com/brad/copymyths.html (By complete coincidence, I have known Brad since he was in high school.)
The starting point is Google. For example, I own Art Garfunkel's Breakaway album, and one of the songs is “I only have eyes for you.” So I Google “I only have eyes for you garfunkel torrent” and get several results. The second one takes me to a site where there's a download link for a “torrent” file. (Torrents are quite small, typically a few dozen KB.) In my file manager, I right-click on the torrent, and select “open with Transmission….” Transmission opens up, but we're not quite done. I need to select the file I want and then click on “open.” If you're lucky, the MP3 will be on your system in a few minutes.
The system is not perfect. You will come across sites which want you to install a “download manager” (for Windows) and most of them are pure malware.
You will also see the terms “seeders” and “leechers.” A seeder is a person who is offering a file, a leecher is downloading. If you want a file and there are no seeders, you will never get it.
It's worthwhile to become familiar with bit torrent downloads, because on the day a new version of Ubuntu is released, by far the best way to get it is by bit torrent.
Clarification: the actual torrent I selected was for the entire Breakaway album – and it downloaded in less time than it took to write this.
Note: music files aren't very big, a typical MP3 is less than 10 MB.
Second note: there's one possible legal glitch with bit torrents. As soon as you have some of the file downloaded, you become a “seeder,” so you might be providing the file to people who do not have the legal right to possess it. That has the possibility of getting you into legal hot water.
Q I asked a question in the Forums, and got no response. How can I keep it active?
A Wait at least 24 hours, and Reply with the word “Bump.” Even better, wait 36 hours, and you will expose the question to people in a different set of time zones.

Tips and Techniques Clean-up Time
Regular readers know that I track the temperatures of the various components of my computer like a hawk. I recently realized that my desktop was running warmer than when it was new, so it was clean-up time.
I keep my computer on a desk, sideways, with the monitor in front of it. Step one was to unplug everything, then move everything but the system unit out of the way. Then I could carry the system unit to my dining-room table where there was room to operate.
The family vacuum cleaner was on the agenda, using the “crevice” tool. Everything which looked like a vent was pretty much covered with a blanket of dust; the vacuum made short work of it. Don't forget USB ports, Firewire ports, audio ports. My desktop has a front panel which pops off, with a filter behind it. I was surprised to see that the filter was pretty clean.
Take off the side panel. Surprise, there's hardly any crud inside the box. Physically remove the video card from the computer. My video card has a fan and a heat-sink with fins. Tiny dust bunnies were living in the fins. A Q-tip cleaned them out. Put the video card back, restore the side panel, put everything back where it was.
Did it work? I was surprised by how well it worked. Measuring everything at idle, the temperature of the hard drive dropped by a full six degrees C. The video card? Twelve degrees. The CPU didn't drop by much, but I can see a big difference when it's running flat-out. Time well spent!
