Q When I tried to install Sopcast in Mint 13, the repository was not found. A Run this command: gksudo gedit /etc/apt/sources.list.d/ferramroberto-sopcast-maya.list In the first line, replace “maya” with “precise”. Save and exit. In Synaptic, reload the sources. Q I have a Samsung R580 laptop running Ubuntu 12.04. When I plug in my HDMI cable to connect it to the TV, I can't get the sound through the TV. A From the volume control in your panel, run Sound Settings. Select the Hardware or Output tab. Select one of the HDMI devices. If that doesn't work, keep going though the HDMI devices. (HDMI/Display Port 4 from Sound Settings → Output was what worked for this laptop.)

Q Quand j'ai essayé d'installer Sopcast sur Mint 13, le dépôt n'a pas été trouvé.

R Exécutez cette commande:

gksudo gedit /etc/apt/sources.list.d/ferramroberto-sopcast-maya.list

Dans la première ligne, remplacer « maya » par « precise ». Sauvegarder et quitter. Dans Synaptic, rechargez les sources.

Q J'ai un ordinateur portable Samsung R580 sous Ubuntu 12.04. Lorsque je branche mon câble HDMI pour le connecter à la TV, je ne peux pas obtenir le son sur le téléviseur.

R A partir du contrôle de volume de votre barre, lancez les Paramétres du Son. Sélectionnez l'onglet Matériel ou Sortie. Sélectionnez l'un des périphériques HDMI. Si cela ne fonctionne pas, faites de même avec les autres périphériques HDMI. (HDMI/Display Port 4 dans Paramètres du Son → Sortie est ce qui a marché pour cet ordinateur portable.)

to do

Q I have just installed Ubuntu 12.04 on a Dell Latitude 2100. I installed the Broadcomm driver and configured my hidden wireless network. All is well. However, if I run the netbook on battery the wireless network speed decreases drastically. A (Thanks to taylorkh in the Ubuntu Forums) The solution was the second suggestion on this web page: http://askubuntu.com/questions/85214/how-can-i-prevent-iwconfig-power-management-from-being-turned-on Q How can I install the latest version of the Openshot video editor? A Have a look at this page: http://www.openshot.org/ppa/ Q I have a 4 page PDF, I need to delete pages 2, 3, and 4. A Try PDF Shuffler. You can get it from the Ubuntu Software Center.

Q Thanks for your help, but my network has a WEP key, do you have to write something different if you have a WEP key? A (Thanks to Chili555 in the Ubuntu Forums) Yes: you log on to your router and change it to WPA2. WEP is about as secure as putting your credit card in a shoebox on the front porch. Q How can you remove a program and all the files? I did: sudo apt-get purge remove quassel A (Thanks to papibe in the Ubuntu Forums) 'remove' conflicts with 'purge'. You need to use just the 'purge' option.

Q Will UEFI kill Linux? A UEFI is OK. Secure Boot is one of its features, and it may become a problem for some Linux distros. Have a look at: http://blog.canonical.com/2012/06/22/an-update-on-ubuntu-and-secure-boot/ Secure Boot might even be beneficial, if it reduces the number of “here today, gone tomorrow,” Linux distros. Q How can I turn off the overlay scrollbars in Ubuntu 12.04? A This web page tells all: http://www.liberiangeek.net/2012/03/disable-ubuntu-overlay-scrollbars-in-ubuntu-12-04-precise-pangolin/ Q How can I have multiple VPN connections at the same time? A See this page: https://www.facebook.com/pages/Ubuntu-Problems/181849281895067

Q In Ubuntu 12.04, after upgrading to the 3.2.0-25-generic kernel, I no longer have any sound. Hp pavilion dv6. A Open a terminal and enter this command: gksudo gedit /etc/modprobe.d/alsa-base.conf Add the following line at the end: options snd-hda-intel model=dell-m4-1 then reboot.

Q I installed a game in Wine, and it put about 30 icons on my desktop. A Move the installer program from Desktop to another folder before you run it. Downloads/nameofgame is a good choice. Q I have a webserver which is running Linux Ubuntu 8.04.4. I would like to install the grads service. A (Thanks to Coffeecat in the Ubuntu Forums) Upgrade to 10.04, and grads is in the repositories.

Tips and Techniques Why Can't Billy Install Ubuntu? I respectfully suggest that this is an education issue, and technology can only solve a bit of it. Here are my top three reasons Billy can't install Ubuntu, or any other version of Linux: - the computer is set to boot from the hard drive, and Billy can't or won't change this, - installation requires changes to “partitions,” and Billy has no idea what those are, - there's a driver issue, and everything Billy knows about drivers no longer applies. I have a good friend who knows a lot about computers; over three decades, he has used them, sold them, written about them. When I suggested that he would need to go into the BIOS settings and “change the boot order,” so his computer could boot from CD or flash drive, that was the end of any talk of trying Linux. He's not sure how to do it, and he has been warned that he could really mess up his computer by changing BIOS settings. It's true, too. Stroke a bunch of random keys and select “save,” and you might need to take the computer back to the dealer, just to get it to run.

If someone asks me how to change the BIOS settings, I can't provide a good answer, unless I have a computer identical to theirs. I've been lucky; turn on my computer and press Delete, and I'm into the BIOS settings on every computer I have owned. On other computers, you need to press ESC, a function key, or something else. There is no industry standard! Many computers do not display what key to press, nor does the information appear in the manual. Once you're into the BIOS settings, you need to read what appears on the screen to figure out what to do next, and you often need to press the “down” key and read what appears, until you discover the magic. Even the method to change the boot order, once you get to the correct screen, is not standardized. If I had information about your computer, at a grotesque level of detail, I could write a program to make it boot from CD or flash drive. However, I couldn't write a program to make every computer boot from CD or flash drive. There are just too many of them, and new ones appear every day.

I'm not going to explain partitions here. You know what they are, but does your cousin? Billy says, “You want me to make three new partitions, but there's no space to make them in!” My friend knows about partitions, and he knows that they are called C:, D: and E:. At least, there is lots of online information about partitions, and even step-by-step instructions about how to deal with them – but they're not something Billy will understand in the first hour. I've been “lucky,” I don't have driver issues with my computers. Well, “lucky” isn't quite accurate; I bought hardware which would work in Linux. Billy might recognize that he has a driver issue, and he knows what the next step is: find the CD which contains the drivers – except when he's trying to install Linux, with one significant exception.

The first driver issue which might come up is the video driver – and often, it's because the video device is too new! There's a work-around, and it works every Tuesday when there is a full moon – or that's what it feels like to Billy. You need to determine the perfect moment to press this key, and then you have to read what is on the screen, again, and we're not used to doing that. Then you type something which isn't a word, and press the magic key… Really? OK, technology could help with this one. A lot.

Finally, there's the network driver. Many (most?) wireless network adapters “just work,” (I've been “lucky.”) Some will work after a bit of effort, some are really horrible, (you need the driver CD!) but they eventually work, and then there are a few which are hopeless. Even wired Ethernet adapters can be a problem, if they are brand new in the market. “It will work next year” isn't a wonderful solution to a person who has a problem today. And yes, technology could help with network adapters. However, the education part is to let Billy know that, instead of searching for the driver CD, he should be getting an exact identification of his hardware, then firing up Google. I would really like to get your thoughts on this: letters@fullcirclemagazine.org
