Q&A 52 - Compiled by Gord Campbell Q I'm trying to fix a problem by modifying a file in the bin folder, but I get “permission denied.” A If you open Accessories/Terminal and enter the command: gksudo nautilus you can change the permissions. Be very, very careful, a wrong click can really mess up your system. Q I want to remap the buttons on an xbox controller. A Use xboxdrv. For information, go to: http://linux.softpedia.com/get/Utilities/xboxdrv-37436.shtml
Q&R 52 - Collecté par Gord Campbell
Q J'essaie de corriger un problème en modifiant un fichier dans le dossier bin, mais j'obtiens un « permission denied »
R Si tu ouvres Accessoires/Terminal et que tu tapes la commande : gksudo nautilus tu peux changer les droits. Sois très très prudent, un mauvais clic peut vraiment mettre tout ton système en l'air.
Q Je veux redéfinir les boutons sur une manette xbox.
A Utilise xboxdrv. Pour info, va à : http://linux.softpedia.com/get/Utilities/xboxdrv-37436.shtml
Q I was decommissioning a machine and deleted some folders while doing so, while connected to Ubuntu One. When I synced my other machines, the folders were removed from them, as well. A (Thanks to duanedesign in the Ubuntu Forums) Programs like DropBox and Ubuntu One are file sync services, they do not make good back up services. The file sync works both ways. Changes made locally are reflected on the cloud and vice versa. So if you remove a folder from the cloud, or your computer, it will be removed from all your computers. If you need to recover a deleted folder please contact Ubuntu One support, and include the name of the folder, and we can try to recover that folder for you. (Gord adds) If you're going to decommission a machine, take it offline and re-partition the hard drive.
Q Je désinstallais une machine et détruisais quelques dossiers, tout en étant connecté à Ubuntu One. Quand j'ai synchronisé mes autres machines, les dossiers y ont été retirés de même.
A (Merci à duanedesign dans les forums Ubuntu) Des programmes comme DropBox et Ubuntu One sont des services de synchronisation de fichiers, ils ne sont pas de bon services de sauvegarde. La synchronisation marche dans les deux sens. Les modifications faites localement sont reportées dans le nuage et vice versa. Donc si vous détruisez un dossier du nuage ou de votre ordinateur, il sera retiré de tous vos ordinateurs.
Si vous avez besoin de retrouver un dossier détruit contactez le support Ubuntu One, et donnez le nom du dossier,et nous essayerons de vous retrouver ce dossier.
(Gord ajoute) Si vous vous apprêtez à désinstaller une machine, débranchez là du réseau et repartitionnez le disque dur.
Q I know Ubuntu is based on a solid foundation of deb. How about rpm? A RPM = Red Hat Package Manager Q Where can I find short lessons on using Linux? A lowfatlinux.com Q My Dell Mini 10V has a 1.6 GHz dual core CPU. However, when I check, the CPUs are running at 800 MHz. A (Thanks to 3rdalbum in the Ubuntu Forums) 1.6 GHz is the top speed of the processors. If they are virtually idle, they will drop back to 800MHz each to save power and reduce heat. If under load, they will shoot back to the full 1.6 GHz each.
Q Je sais qu'Ubuntu est basé sur de solides fondations de paquets deb. Pourquoi pas rpm ?
A RPM = Red Hat Package Manager
Q Où puis-je trouver des cours rapides sur l'utilisation de Linux ?

Q Mon Dell Mini 10V a un CPU dual core à 1,6 GHz. Cependant, quand je vérifie, les CPUs tournent à 800 MHz.
A (Merci à 3rdalbum dans les forums Ubuntu) 1,6 GHz est la vitesse maximale des processeurs. S'ils sont virtuellement en attente, ils vont tomber à 800 MHz chacun pour économiser de l'énergie et réduire la température. Chargés, ils seront de nouveau propulsés à 1,6 GHz chacun.

Q I'm trying to set up Ubuntu Server 11.04 as a home file server, and I'm having some issues. A It's much, much easier to install Desktop Ubuntu (perhaps the long-term release, 10.04), then use the Nautilus file manager to create and share (under the right-click menu) some folders. “Server” is really meant for “headless” (no monitor, no keyboard) computers hosting high-volume web sites, or other applications where performance is an issue. Q My Ubuntu is messed up so badly it will not boot. I have a LOT of files on the hard drive which I cannot afford to lose. How can I reinstall Ubuntu so I do not damage my files, and be able to pick back up where I left off? A Hard drives fail! If you can't afford to lose the files, you must have backup. Go to your favorite computer store and buy two external hard drives which are each large enough to hold your data. Boot from a LiveCD, plug in an external hard drive, and copy your files onto it. Take the drive somewhere that it will not be destroyed if your home burns down. Plug in the other drive, and make another copy, which you can put in a safe place where you live. Once that's done, begin thinking about reinstalling Ubuntu.
Q I recently installed K9Copy and a lot of other packages were installed along with it. Now I want to uninstall it, but only K9Copy uninstalls. How can I find and uninstall all the dependent packages that came along with it? A (Thanks to Chiel92 in the Ubuntu Forums) Open Accessories/Terminal and enter this command: sudo apt-get autoremove Q I recently switched to Ubuntu. There seems to be no specific driver for my video adapter, an SiS M760G. A It's a basic, cheap video adapter, which provides basic functions. You can't expect much more from a six-year-old, low-end laptop. Q I have done a clean install of 11.04 but I'm having a little trouble finding drivers for my Broadcom BCM4306 802.11 b/g wireless. A (Thanks to IWantFroyo in the Ubuntu Forums) You can go into Synaptic and search for 'b43'. There will be three firmware packages, each with a list of the cards they support in the description. Your card should be there somewhere.
Q I want to combine several MP3s into a single playable file. A Run Synaptic Package Manager and install mp3wrap. It is a command-line program, so you use Accessories/Terminal to run it. Q I am trying to share a USB external drive, formatted as NTFS, from my Ubuntu computer to my Windows systems. A (Thanks to Morbius1 in the Ubuntu Forums) Add a “force user” line to your smb.conf for the drive: [HDMovies] path = /media/HDMovies comment = HD Movies 01 public = yes only guest = yes guest ok = yes force user = jynks After saving, restart Samba with this terminal command: sudo service smbd restart
Q What's the deal with the new laptops with “switchable graphics,” also known as “Nvidia Optimus”? A http://ubuntuforums.org/showthread.php?t=1657660 and https://github.com/MrMEEE/bumblebee#readme. Q How can I set up a web site with a cart application able to handle transactions and payments? A Moneybookers.com has a good description of their simple API and more in-depth details on payment. Q If I try to start my Lenovo G475 notebook without the adsl cable plugged in, it crashes! A (Thanks to drivard.com) Turn on the Network Boot feature in the BIOS. (Holding F2 at boot up probably gets you into the BIOS setup on these computers.) This also affects some Acer notebooks.
