Q I have a high-end Nvidia graphics card, and Ubuntu 12.04 doesn't like it at all. A To boot, hold shift from the BIOS boot to get a Grub menu. Press “e” on getting the Grub menu. Using the arrow keys, navigate to, and delete, quiet and splash, and type the word nomodeset in their place. Press Ctrl-x to boot. Add this in Software Sources: ppa:ubuntu-x-swat/x-updates Now you can install a later version of the video driver, which works for most systems.
Q J'ai une carte graphique Nvidia haut de gamme, et Ubuntu 12.04 ne l'aime pas du tout.
R Pour démarrer, maintenez la touche majuscule lors du démarrage du BIOS pour obtenir un menu Grub. Appuyez sur « e » dans le menu GRUB. En utilisant les flèches, allez sur, et supprimez, « quiet and splash », et tapez le mot nomodeset à leur place. Appuyez sur Ctrl-x pour démarrer.
Ajoutez ceci dans Sources de logiciels: ppa:ubuntu-x-swat/x-updates
Maintenant, vous pouvez installer une version plus récente du pilote vidéo, qui marche pour la plupart des systèmes.
Q I am using Ubuntu 12.04, 64-bit. Skype sees that I have a webcam, but it doesn't send images. A Install the ia32-libs. Launch Skype with this command: bash -c 'LD_PRELOAD=/usr/lib/i386-linux-gnu/libv4l/v4l1compat.so skype' It seems v4l1compat.so moves around from version to version.
Q J'utilise Ubuntu 12.04, 64-bit. Skype voit que j'ai une webcam, mais il n'envoie pas les images.
R Installez les ia32-libs. Lancez Skype avec cette commande:
bash -c 'LD_PRELOAD=/usr/lib/i386-linux-gnu/libv4l/v4l1compat.so skype'
On dirait que v4l1compat.so se déplace d'une version à l'autre.
Q When I try to open Software Center, it opens and then closes before I get a chance to use it. A Run these commands: sudo apt-get update sudo apt-get upgrade Q How do I set Shotwell NOT to start when I insert a disk, or SD card, or Flash drive with pictures on it? A If you're on Precise, the setting is in System Settings > System > Details > Removable Media. Q My wacom tablet doesn´t work in ubuntu 12.04. A Google: Wacom tablet drivers launchpad Download the .deb file, install it, and reboot.
Q Lorsque je tente d'ouvrir le Centre de Logiciels, il s'ouvre et se ferme avant que j'ai la possibilité de l'utiliser.
R Lancez ces commandes :

Q Comment puis-je configurer Shotwell à ne PAS démarrer lorsque j'insère un disque ou une carte SD ou un lecteur flash avec des images dessus ?
R Si vous êtes sur Precise, le réglage est dans les Paramètres Système> Système> Détails> Médias amovibles.
Q Ma tablette Wacom ne fonctionne pas sous Ubuntu 12.04.
A Google: Wacom tablet drivers launchpad Télécharger le fichier .deb, installez-le et redémarrez.
Q I have a printer attached to my Ubuntu desktop. I would like to print on it from my Windows netbook. A See this web page: https://help.ubuntu.com/community/NetworkPrintingWithUbuntu Q How can I install Sopcast (peer-to-peer streaming, mostly Chinese, TV) in a recent Ubuntu? A Add the following to your software sources: ppa:ferramroberto/sopcast After a reload, you can install sopcast. Q Where are the log files in ubuntu 12.04? A (Thanks to cc7gir in the Ubuntu Forums.) /var/log/syslog

Q Comment puis-je installer Sopcast (streaming peer-to-peer, principalement en Chinois, TV) dans une version récente d'Ubuntu?
R Ajoutez ce qui suit à vos sources de logiciels: ppa:ferramroberto/sopcast
Après un redémarrage, vous pouvez installer sopcast.
Q Où sont les fichiers journaux dans ubuntu 12.04?
R (Merci à cc7gir dans les forums Ubuntu.) /var/log/syslog
Q My computer has a GeForce FX5200 video card. Aptitude won't install the nvidia-173 package. A (Thanks to papibie in the Ubuntu Forums.) The oldest versions of the driver (173 and 93) are not compatible with the new versions of Ubuntu; actually any Linux distribution using an up-to-date version of Xorg. For now, I would recommend using the default open source driver, called nouveau. These days it is working pretty well supporting Nvidia cards. Q How can I create a list of all the programs on my PC? A Open Terminal and paste this command: dpkg -l > Desktop/applist.txt That will put a file on your desktop, listing all the “packages” on your computer, with descriptions. The list is probably a lot longer than you expected.
Q Mon ordinateur est équipé d'une carte graphique GeForce FX5200. Aptitude ne voudrait pas installer le paquet nvidia-173.
R (Merci à papibie dans les forums Ubuntu). Les plus anciennes versions du pilote (173 et 93) ne sont pas compatibles avec les nouvelles versions d'Ubuntu, en fait avec n'importe quelle distribution Linux qui utilise une version mise à jour de Xorg. Pour l'instant, je vous conseille d'utiliser le pilote open-source par défaut, appelé « nouveau ». Il fonctionne assez bien en ce moment avec les cartes Nvidia.
Q Comment puis-je créer une liste de tous les programmes sur mon PC?
R Ouvrez un terminal et collez la commande suivante:
dpkg -l > Desktop/applist.txt
Cela va mettre un fichier sur votre bureau, la liste de tous les « paquets » sur votre ordinateur, avec des descriptions. La liste est probablement beaucoup plus longue que ce à quoi vous vous attendiez.
Q How to play .rm files in Ubuntu 12.04 64-bit? A Those are Real Media files. Use Gnome mplayer. VLC might handle them. Q When I tell my computer to shut down, it goes through all the motions as if it will shut down, but then it stays on. A Add acpi=force in grub with these commands: gksudo gedit /etc/default/grub find the line which looks like this: GRUB_CMDLINE_LINUX=“” Change it to: GRUB_CMDLINE_LINUX=“acpi=force” save the file and exit, then run: sudo update-grub It won't help until after you reboot.
Q Comment jouer un .rm dans Ubuntu 12.04 64 bits?
R Ce sont des fichiers Real Media. Utilisez Gnome Mplayer. Il se peut que VLC les traite.
Q Quand je dis à mon ordinateur de s'éteindre, il passe par toutes les étapes, comme si il se fermait, mais ensuite il reste allumé.
A Ajoutez acpi=force à grub avec ces commandes:
gksudo gedit /etc/default/grub
Trouvez la ligne qui ressemble à ceci: GRUB_CMDLINE_LINUX=“”
Changez-la en: GRUB_CMDLINE_LINUX=“acpi=force”
Enregistrez le fichier et quittez, puis lancez:
sudo update-grub
et çà sera bon après un redémarrage.

Q How can I use an external monitor with my Asus netbook? A Install Arandr. For more information: http://www.ubuntugeek.com/arandr-a-simple-visual-front-end-for-xrandr.html Q How can I install TTF fonts in Ubuntu? A There are two methods at: http://www.wikihow.com/Install-TrueType-Fonts-on-Ubuntu Q Can I develop and run Visual Basic applications in Ubuntu? A Yes. See http://monodevelop.com/ (This was the biggest surprise of the year for me!)
Q My Sennheiser HD 201 headphone works fine with Windows 7 and even with my Galaxy smartphone. But when I use it in Ubuntu, I can hardly hear any sound. The volume is very low. A In ALSAmixer, change the “Front”, “Side” and “Center” levels. Even though the headphone value stays at zero, the headphones should work nicely. Q Where should I put environment variables? A See: https://help.ubuntu.com/community/EnvironmentVariables#System-wide_environment_variables Put them in /etc/environment
Q I have a 70 GB SSD and a large hard drive in my laptop. I want to ensure my personal data is encrypted, but still take advantage of the speed of the SSD for loading programs. How should I set it up? A During installation, put your root partition (/) on the SSD, and /home and swap on the hard drive. Specify that you want /home encrypted. Select a powerful password, more than eight characters, with upper and lower case letters, numbers, and other symbols. A lot of the space on your SSD will be wasted, but that's life. Q Why does Ubuntu use the Linux kernel instead of the Linux-libre kernel? A (Thanks to 3rdalbum in the Ubuntu Forums) It's better to enable people to use Linux, than to prevent them from using Linux.
Tips and Techniques It's Mint Spring of 2012 was time to choose a new “primary computing environment” to use for the next few years. For me, 64-bit Linux Mint 13 with Cinnamon is the answer. I was happy with Ubuntu 10.04, but 10.10 improved the support for my AMD Phenom II processor. It was my primary system until April 10, 2012, when Canonical dropped support. (They could have at least kept it going for the few days until Ubuntu 12.04 was released.) I had an open partition, so I installed Mint 12 with Cinnamon.
It works the way I work! All my hardware works, it took about 20 seconds to install my printer. I can share a folder and access shared folders. My video adaptor is well supported. There's a program menu and a single panel at the bottom, so most of the screen real-estate is available. Conky works, there's a weather applet, the date is available in a pleasing format. It uses Nautilus as its file manager. (I wanted to like Kubuntu, but its file manager made me crazy.) The buttons are where I like them. Menus are part of the program's window. Skype works (see above) and the Youtube HD extension automatically picks the resolution I prefer. When Mint 13 became available, I installed it on my laptop. Works nicely. (I also have Ubuntu 12.04 on the laptop, and it works nicely, but not the way I work.) The desktop installation went smoothly. My “primary computing environment” is defined by where my real email is, and where I run Miro, my podcast catcher. I still use Evolution for email, and have become expert at backing it up here, and restoring it there. Similarly, I export my web bookmarks here and import them there. I'm chicken, so I still backup my files before installing a new version, even though I've never lost anything during installation.
Cinnamon is not perfect. I've run into a couple of minor bugs, but I could work around them. I expect it will only get better. Even though I test new versions/distros frequently, moving to a new version is not my favorite activity. Like Ubuntu 12.04, Mint 13 is a long-term support release. It's possible I will use it until 2016, when Ubuntu 16.04 will go up against Mint 17. By then, I might even find a compelling reason to get a new computer. (My Phenom II is almost three years old.) Or maybe, by then, we will all be using tiny, low-power computers based on the ARM architecture. Ain't change great?
