Q What is the easiest way to get rid of old kernels? A (Thanks to Bashing-om and morgaes in the Ubuntu Forums) Run these commands: sudo apt-get update sudo apt-get dist-upgrade Reboot. One more command: sudo apt-get autoremove It's a new use for “autoremove.”

Q Quelle la façon la plus rapide de se débarrasser des vieux noyaux ?

Q I went and bought this WNDA3100v2 N600 Wi-Fi adapter; now I need help setting it up. A If you can follow these instructions, you should be OK: https://help.ubuntu.com/community/WifiDocs/Driver/Ndiswrapper Generally, it's a good idea to Google “[device name] linux” before buying hardware. Many USB Wi-Fi adapters work as soon as you plug them in and reboot, but printers, webcams, and Wi-Fi adapters, have varying levels of support. Q I use VLC media player to watch TED Talk videos, but I would like to download them instead. A (Thanks to mc4man in the Ubuntu Forums) The TED site supports downloading, but it's not obvious. When you select a video in your browser, there is a “download” button. That starts the video playing, but you can pause it, then right-click in the video and select “save video as”.

Q Je viens d'acheter l'adaptateur wifi WNDA3100v2 N600 ; maintenant, j'ai besoin d'aide pour le configurer.

R Si vous pouvez suivre ces instructions, tout devrait être OK : https://help.ubuntu.com/community/WifiDocs/Driver/Ndiswrapper

En général, c'est une bonne idée de rechercher sur Google « [nom du matériel] linux » avant d'acheter des équipements. Beaucoup d'adaptateurs wifi par USB fonctionnent dès qu'on les branche et qu'on redémarre, mais les imprimantes, les webcams et les adaptateurs wifi ont des niveaux d'assistance très variables.

Q J'utilise VLC media player pour regarder les vidéos de TED Talk, mais je préférerais les télécharger.

R (Merci à mc4man sur les forums Ubuntu) Le site TED acceptent le téléchargement, mais ce n'est pas trivial. Quand vous sélectionnez une video dans votre navigateur, il y a un bouton « download ». Il démarre la lecture de la vidéo, mais vous pouvez la mettre en pause ; ensuite, faites un clic droit sur la vidéo et sélectionnez « save as ».

Q I added a ppa and installed simplescreenrecorder. How can I completely remove it? A (Thanks to deadflowr in the Ubuntu Forums) Simplescreenrecorder installs two packages, so use these commands: sudo apt-get purge simplescreenrecorder* sudo add-apt-repository –remove ppa:maarten-baert/simplescreenrecorder sudo apt-get update Q How do you delete Windows software installed in 14.04 using the program's native installer (not through WINE)? A The uninstaller is also a Windows program, so you may be able to uninstall using an uninstall program UNDER WINE. Many applications do not include an uninstall program, so all you can do is delete the files. The general approach is this: in your file manager, set it to display “hidden” files and folders. In your home folder you will find a folder called .wine, and under it is drive_c, which corresponds to a C: drive in Windows. It contains Program Files, among other things. My own approach is to leave things alone until I do a re-install of a new version, such as Ubuntu 16.04 LTS. Deleting a single movie saves more space than dozens of programs. Q Today, Xubuntu 14.04 software update installed the same kernel 3.13.0.46 for the third time. Why? A It was actually 3.13.0-46.75, and there was a regression requiring the updates.

Q J'ai ajouté un PPA et installé simplescreenrecorder. Comment pourrais-je l'enlever complètement ?

R (Merci à deadflowr sur les forums Ubuntu) Simplescreenrecorder installe 2 paquets ; utilisez donc ces commandes :

sudo apt-get purge simplescreenrecorder*

sudo add-apt-repository –remove ppa:maarten-baert/simplescreenrecorder

sudo apt-get update

Q Comment effacer un logiciel Windows installé dans la 14.04 en utilisant l'installateur intégré du programme (et pas par l'intermédiaire de Wine) ?

R Le dés-installateur est aussi un programme Windows ; ainsi, vous devriez pouvoir désinstaller en utilisant ce programme de désinstallation DANS WINE.

Q Is there any way to synchronize Evolution Mail and my Hotmail account? A (Thanks to sandyd in the Ubuntu Forums) See this web page for IMAP and SMTP settings that can be added to evolution: http://windows.microsoft.com/en-us/windows/outlook/send-receive-from-app# Q My system sometimes locks up. I would like to know the exact time my system locks. A Run conky, and include the time in the conky display. Q In a text file, once the line containing “Heading” is found, how can I display the next 20 lines? A (Thanks to Lars Noodén in the Ubuntu Forums) Grep can do this: grep -A 20 Heading /path/to/somewhere/somefile.txt
