• play sound from different applications on different output devices (speakers, headphones)

  - by Mike

  I want music (played e.g. via Audacious) to be played on speaker system, and all other sounds produced by other applications (including ubuntu sound effects) to be played on headphones. My computer has sound connectors at its back, and also connectors on its front panel. When I connect both headphones and speakers, only headphones work (I take it, the front connectors take precedence?). Should I purchase another sound card (in addition to the motherboard-integrated sound I have)? When I go to Audacious output settings, I see only the ouput plugin selection list, with PulseAudio selected and options like ALSA, OSS4 etc. But there's no facility to select particular output device (and I guess it wouldn't magically appear even if I had the second soundcard). Is this at all possible to bind specific application to particular output device?

• Problem: Black screen after resume

  - by Robert

  Problem: Black screen after resume I found the below statement that I provided the link for but, no instructions with it for a person that's new to Ubuntu on what exactly to do to fix the problem. Can someone clarify this for me? Thank you. Ubunu 13.10 AMD A6-3420M APU with Radeon(tm) HD Graphics × 4 64bit Toshiba L775 My computer boots to a black screen, what options do I have to fix it? Typical scenario is "use a laptop docked with lid closed, only the external screen is active, suspend, take the laptop, open it somewhere"... which leads to "no screen active". To debug this problem, check if gnome-settings-daemons is getting a signal that the display configuration has changed, by running xtrace against it, and look for a RRScreenChangeNotify event when resuming the machine. If that signal is being sent, then it indicates a possible bug in g-s-d. Otherwise, it suggests a bug in either X or (more likely) the kernel which is not causing the signal to be emitted to begin with.

• JavaOne 2012 demo of Java SE Embedded on Raspberry Pi

  - by hinkmond

  Here's the Inquirer's article about our Java SE Embedded demos at JavaOne 2012 this year. Simon Ritter had a fun presentation showing the cool demo on the Raspberry Pi at his talk. See: Demo Java SE Embedded on Raspberry Pi Here's a quote: Oracle demonstrated Java SE for embedded devices running on the Raspberry Pi bare bones computer at the Java One show on Wednesday, with the aim of encouraging developers to try it out for themselves to create reference libraries for the target school children audience. I had the presentation after Simon and saw the size crowd he had. They were laughing and clapping at the demo and having a good ol' time. Good to see the interest in Java SE Embedded, even if it is for a "toy" device like the Raspberry Pi. Hinkmond

• How to install flareGet_1.0-1(beta)_deb_rpm.tar.gz?

  - by Suhail cholassery

  I have lot about Flareget download manager and I wanted to install it in my computer. I visted the website and dowloaded the the file flareGet_1.0-1(beta)_deb_rpm.tar.gz and saved it in the location /home/suhailcholassery/Download/flareGet_1.0-1(beta)_deb_rpm.tar.gz. The thing is that I am new to Ubuntu and don't know how to install it. I tried typing the following command in terminal as per the readme's instruction enclosed in file. yum install flareGet-1.0-1.i386.rpm, but the reply was the following: You need to be root to perform this command. And I don't know how that is to be done. Isn't there any simpler way for installing this package?

• Best strategy to discover a web service in a local network?

  - by Ucodia

  I am currently doing some research for a project. The setup is simple, I have a computer running a service in my home network and any device connected to that same network should be able to discover the service automatically and use it. I have no specific technology requirement whether it is on the server or client side. The client knows about the service definition. Other than that I have no idea what strategy to use, what technology to look at or whether I should go for a SOAP or a HTTP based service. I think going HTTP with REST API is the best for targeting all devices but I am opened to any suggestions. Thanks.

• How do I turn off all the password prompts?

  - by Barkerto

  I've been using Ubuntu 12.04 LTS since release and am trying to figure out a couple things about all of these passwords and key-ring prompts that I've just been living with for a while. Ever since install it seems that every time I boot up my computer and want to do anything (ie. use the internet, use a internet browser, install something, delete something, pick my nose) I'm always prompted for either a normal password entry or a key-ring password entry. Is there anyway to turn off all of this "security" and tell my Ubuntu that it can trust what I'm doing and go take a shower? Thank You in advance, barkerto

• Breaking in to Programming

  - by Kevin

  I've noticed that there is a gap between getting formal education in computer science as a student and entry-level/junior programming jobs. Obviously entry-level programming requires that you know some programming but how much do you need to break in? I'm in a QA non-coding role with basically a minor in CS, looking to improve my own programming skills to eventually switch industries. However I'm completely at a loss as to what I should be focusing on learning and am curious as to the steps other people have taken to get experience post-undergrad.

• Survey says: Java technology rules

  - by hinkmond

  Eclipse came out with their Open Source Developer Report and Survey for 2012. In it, we see (in the words of the immortal Richard Dawson, RIP) "Surveys Says!": Java computer programming language is on top. See: Java is the top Here's a quote: The Eclipse community was invited to participate in the survey between April 23 and May 15 of this year. Skerrett says the Foundation promoted the survey primarily through social media (Facebook, Twitter) and online forums. Of the 840 people who responded, 732 completed the survey... So, now we know who's on top, we can keep this in mind the next time this question comes up on Family Feud. Hinkmond

• Backtrack 5 R2 Dual-Boot w/Windows 7 No Longer Loads

  - by dstars5

  A while back, I installed Backtrack 5 R2 to Dual Boot on a Windows 7 PC. It worked fine for a while, but now when I try to load it, the screen gets all messed up (tried to get a picture with my phone, but it wasn't working too well). The last line before it freezes says: fb: conflicting fb hw usage: nouveaufb vs VESA VGA - removing generic driver Since it last worked, the only changes I can think of are that the computer is now connected via ethernet cable to the router, and I upgraded the graphics card (to nvidia). Because of the last line, I personally would put my money on the latter, but I still have no clue how to fix this. Can someone help me? Thanks!

• What You Said: How Do You Set Reminders?

  - by Jason Fitzpatrick

  Earlier this week we asked you to share your favorite tricks for staying on top of your tasks with timely reminders. Now we’re back to highlight some great reader tips (including a bit of software older than some of our readers). Most of us have to-do lists longer than we can do in a given day (or week!) and a constantly changing set of demands and next-actions. Having a timely and effective reminder system is the difference between dropping the ball and getting things done; how exactly that reminder system plays out, however, varied greatly from reader to reader. OJMDC sticks with analog reminders: Sticky notes in the middle of my monitor and in my wallet. I’ve tried my phone apps but I typically disregard them. HTG Explains: Is UPnP a Security Risk?

• How to grant standard users access to disk partitions and flash storage?

  - by JK04

  I have a partition that I need standard users (not administrators)to have read/write access to. However, this partition does not even appear to them as it does to me as an administrator. How can I make it so that standard users can read/write to this partition? It would be nice if they could have the ability to mount it if needed. I have the same problem with removable media - if I have a flash card in the computer, the standard users cannot see this storage media.

• If a variable has getter and setter, should it be public?

  - by Oni

  I am an about to graduate Computer Science student so probably this is a stupid question. If I have a class with a variable that is private and the class have getter and setter for that variable. Why don't make that variable public? The only case I think you have to use getters and setters is if you need to do some operation besides the set or the get. Example: void my_class::set_variable(int x){ /* Some operation like updating a log */ this->variable = x; } Thanks in advance!

• How Data Transfers differ on Smart Phones: Iphone vs. Android vs. Windows Phone

  - by MCH

  I am interested in how each individual smart phone is allowed to handle data transfers within a third-party app. I am interested in designing apps that allow customers to update, transfer, download, etc. data from their smart phone to their personal computer and vice-versa. (Ranging from just text, to XML, to a Relational Database) I only have experience with the Ipod Touch before and one particular app that maintained all the data on an online server, so to update the data on your pc or iphone you had to go online, are there other ways to do it? Like bluetooth, wireless LAN, USB, etc? I believe Apple has certain policies on this in order to control the App Store and individual Iphones. I suppose each company has a particular policy on how an app is allowed to transfer data to another system, does anyone have a good understanding of this? Thank you.

• What is the reason for high power consumption in 12.04?

  - by tom

  I haven't seen this exact question posted or any related answers, so I'm re-posting. Here is the problem: After upgrading to Ubuntu 12.04 Precise Pangolin, my t420s laptop idles above 20 watts (right now with only Chrome running, I'm using 25.4 W) I had a similar problem with Ubuntu 11.10, but after much tweaking the power consumption came down < 10 W on idle. The primary culprit to the 11.10 problem was supposedly fixed by default in 12.04. So my question is, what is happening now? Computer: Lenovo Thinkpad t420s, with Intel i5-2520M @2.5 Ghz - 2x 4gb ram - disk 0 HITACHI 320 Gb - disk 1 SATA SSD 128 Gb

• Windows 7 won't boot? Tried Boot Repair (dual-boot)

  - by user206870

  I downloaded Ubuntu and installed it so that my computer was dual boot. The first day, Ubuntu and Windows both worked great. Unfortunately, the next day, after messing around on Compiz Config Settings Manager to get the rotation cube, I tried booting into windows 7, and it wouldn't boot. It just goes to the screen where the Windows logo comes up and says Windows 7, and then reboots without even displaying an error message. I tried boot repair and it didn't work, the problem's still there. How can I fix this? PS: here's the link that boot repair gave to me: http://paste.ubuntu.com/6287090

• How to remove username from "Me" menu (right near to power button on the top panel)? [closed]

  - by Ivan

  Possible Duplicate: How do I replace the MeMenu username with my actual name? My user name takes approximately as long as would 6 icons. I don't need to see my username, I am the only user of my computer. How can I remove it? I use Ubuntu 10.10. UPDATE: The answer found: gconftool -s /system/indicator/me/display --type int 0 UPDATE: Unfortunately the solution doesn't work any more. Now it totally removes the instant messaging menu (including the icon) instead of just removing a name.

• Elantech trackpad being identified as a logitech wheel mouse

  - by user11895

  I recently purchased a Samsung RF510 laptop computer, which I absolutely love. However, upon installing Ubuntu 10.10 onto it I couldn't get the trackpad to function properly. It worked as a basic mouse (point and click) but had no functionality for edge scrolling or any of the multitouch settings the trackpad is capable of. After doing a lot of research I discovered the reason is a known issue where the Ubuntu kernel will improperly detect an Elantech trackpad as a logitech PS/2 wheel mouse, and as such will gain none of the functionality that seems to be coded for synaptics trackpads. The question I have is: does anyone know a way to get this working properly? This is my first time trying to run Ubuntu on a laptop (actually, it's my first laptop in the last 12 years) and I'm finding the experience to be intolerable without the basic scrolling/zooming/etc I've been used to using for as long as I can remember.

• Function keys and Hot are switched

  - by Brian

  I recently got a new laptop and installed 12.10 on it. I noticed right away that the "hot keys" on the F keys didn't always do what was pictured and also I noticed that the "hot keys" and the function keys were reversed. e.g. to close a window I have to hit alt-fn-F2 instead of just alt-F2. This is pretty annoying because I've been using the same keyboard shortcuts for years and I don't really want to have to re-learn them. I would also like to switch what the hot keys do, for example the F3 key is pictured as increase screen brightness but it really puts the computer to sleep. I would like to change this back to increase the brightness I looked in keyboard shortcuts settings but these options are not in there. I also downloaded gconf-editor but was unable to find where to change the shortcuts on it. (they weren't at apps \ metacity \ keybinding_commands like others described) any help would be greatly appreciated

• Flickering/Flashing screen problem related to keyboard

  - by LeandroCR

  This will seems quite bizarre but that's a huge problem for me, I'm facing it for a long time since Ubuntu 12.04. My Ubuntu/Linux Mint/Debian (Unity/Gnome) always starts flickering after using the computer for a while, I always thought this had something to do with the video board. I have an Vostro 3550 (Radeon 6xxx/Intel Onboard). First I realized that when I was navigating trough an website, when i selected with the mouse a combo, the combo closed it self automatically then the screen starts flickering. The i realized when i was trying to make the login in the terminal (crtl + alt + f1) a strange character appears, like: ^@ repeatedly. When i keep CRTL pressed the system never flickers! I have absolutely no problem using Windows. What can i do? There is no such thing as Keyboard driver on Dell Support. I would love to use Ubuntu only, but this is very annoying. Problem happens on Ubuntu 12.04, .10 and 13.04 Linux Mint 15 (Cinnamon) Debian Live with Gnome

• Can I use GNOME-applets in Unity?

  - by Moma Antero

  Hello, Applets are small programs that you attach and start from the GNOME's toolbar. See picture: http://www.futuredesktop.com/audio-recorder/recorder-applet.ogv My favourite applets are: rec-applet: Smart audio recorder applet. You can get this from Launchpad. clipart-finder: Find and download clipart to your computer. You can get this from the Launchpad. 1) Can I use these applets in UNITY as is? 2) What changes I have to make to applets' code (rec-applet and clipart-finder) to make them usable in Unity? 3) Where is the applet-specification for Unity?

• What is the history of why bytes are eight bits?

  - by DarenW

  What where the historical forces at work, the tradeoffs to make, in deciding to use groups of eight bits as the fundamental unit ? There were machines, once upon a time, using other word sizes, but today for non-eight-bitness you must look to museum pieces, specialized chips for embedded applications, and DSPs. How did the byte evolve out of the chaos and creativity of the early days of computer design? I can imagine that fewer bits would be ineffective for handling enough data to make computing feasible, while too many would have lead to expensive hardware. Were other influences in play? Why did these forces balance out to eight bits? (BTW, if I could time travel, I'd go back to when the "byte" was declared to be 8 bits, and convince everyone to make it 12 bits, bribing them with some early 21st Century trinkets.)

• Why can't I get into my repositories?

  - by ken1943

  Upgraded from 10.04 to 10.10 by mistake and am having problems with some of my programs. They either don't work or they disappear from view on the screen. The Repositories menu item in Synaptic Packages Manager is a case in point. The computer does nothing when I choose this item. I am locked out of unless I edit /etc/apt/sources.list. The rest of the application seems to work, however. Update Manager just flashes on screen then disappears without doing, as does Printing. How do I downgrade from a higher to a lower level repository? I need to downgrade from 10.10 to 10.04. Each time Ubuntu upgrades to 10.10 evil things happen and the operating system really gets messed up. I really do not want to have to erase and install my operating system all over again if I can help it.

• Cable connection takes a lot to establish

  - by user162237

  I've just installed Xubuntu on my computer. It's all OK, but I have a problem with the internet connection: when I boot the PC and I login into Xubuntu it says to me "Cable connection disconnected" or "No cable connection". After a while (like 40 seconds) it connects to the internet and then I'm able to surf the net. I was wondering: why it takes so long to establish a connection? I had no problems of this kind on Windows or other distributions. EDIT: here are some outputs: http://pastebin.com/8nWFC5BV

• Is there any way to downgrade or revert an update to the kernel?

  - by David

  Today I installed the linux 3.9 Kernel update (because I heard it would fix sound through HDMI which I no longer have since installing 13.04). After restarted my computer and logging in my screen has only a desktop, and no dock or tool bar. I tried to reset unity and compiz using guides like this one but nothing happens, even after reboot. Is there any way to downgrade or reset the update? EDIT: Running uname -a in terminal brings up 3.8.0 as my current kernel for some reason.

• Reliability Monitor is the Best Windows Troubleshooting Tool You Aren’t Using

  - by The Geek

  When it comes to hidden gems in Windows, nothing beats the Reliability monitor tool, hidden behind a link inside of another tool that you don’t use either. Why Microsoft doesn’t shine more light on this really useful troubleshooting tool, we’ll never know. Reliability Monitor tracks the history of your computer — any time an application crashes, hangs, or Windows gives you a blue screen of death. It also tracks other important events, like when software is installed, or Windows Updates loads a new patch. It’s an extremely useful tool. And yes, it’s in Windows 7 and 8… and even 8.1. It might be in Vista, but who uses that anymore?
