  • Byobu not displaying correct CPU temptrature

    - by aserwin
    I have an AMD FX 8120 proccy that is overclocked to 4100Mhz. Since the overclocking, Byobu and other temprature reading apps (Conky, etc) do not read the temprature accurately. I can see the correct temp in the bios, and with no overclocking everything inside of Gnome reads correctly. Why should this be? It is (seemingly) obviously an issue with Ubuntu (or perhaps Gnome?). Has anyone else experienced this?

  • my application icon won't show in Ubuntu 12.04 session fallback mode

    - by Nelson Teixeira
    I have a Python application that shows a systray icon, but it just won't appear in Ubuntu 12.04 session fallback mode (Gnome Classic WITH effects). It appears in 10.04, and in 12.04 with Unity. The problem is just in Gnome Classic. I've already set: gsettings set com.canonical.Unity.Panel systray-whitelist "['all']" and I installed indicator-applet-complete but Alt-Win-right click won't work Anyone has any idea what can be wrong ?

  • Uninstall Caribou?

    - by Icedrake
    I just installed the Gnome Tweak Tool in order to change my icon theme to Faenza, but it seems to have installed some other program named Caribou, which I think is an onscreen keyboard program, with it. This is absolutely useless for me, and frankly, I hate the fact that it was installed silently and without my permission. When I go to uninstall it, it says that it's part of gnome-shell and requires the un-installation of that as well. What do I do?

  • Way(s) of browsing the filesystem that are more flexible

    - by ixtmixilix
    I have two related questions, both probably (but not necessarily preferentially) accepting the same answer : When browsing or exploring the filesystem in a GUI, I want to be able to right click on the empty space between the files, choose a menu item and say 'open terminal in this folder,' optionally as root Do the converse when using the terminal, optionally as root I use Universe with kubuntu but have Debian Lenny running with gnome installed separately, so anything on kde or gnome would work

  • GUI for editing Menu in Xubuntu

    - by Borsook
    I see that Xubuntu has package Gnome-menus, but I cannot find the command to run the editor it should contain. I found a small editor but it does not allow new entries and alacarte tries to install whole Gnome... So I'm looking for a menu editor that will allow me to: Add new launchers, Edit existing ones Move existing ones to different categories Create new categories Won't install bazillion dependencies :)

  • Ubuntu 14.04 Slow, High CPU Usage

    - by user273012
    I experienced CPU strange behavior after installing Ubuntu 14.04, at 5 or 10 minutes, CPU usage suddenly increased about 50%, that's really slow my laptop down (Ubuntu 13.10 worked fine by the way) Here is my laptop specs : ASUS A43SA Intel Core i3-2330M 2.20 GHz 4 GB of RAM I noticed this when the first installation, even after I disabled online and file search, even after I switch to GNOME 3, and even after I used GNOME Fallback Session, how to solve this?

  • Ubuntu is stuck when it goes to sleep mode in fullscreen

    - by hatter
    If there is a full screen terminal running when Ubuntu goes to sleep, it becomes stuck. This is not the problem with gnome-terminal as sometimes firefox in full screen also causes this problem. With firefox this doesn't happen every time. But with gnome-terminal this happens everytime and as explained in this answer, I use killall command and kill the application. Is this a bug and what can be done to aviod this?

  • Creating Descriptive Flex Field (DFF) Bean in OAF

    - by Manoj Madhusoodanan
    In this blog I will explain how to add a custom DFF in a custom OAF page.I am using XXCUST_DFF_DEMO table to store the DFF values.Also I am using custom DFF named XXCUST_PERSON_DFF.  Following steps needs to be performed to create this solution. 1) Register the custom table in Oracle Application2) Register the DFF3) Define the segments of DFF4) Create BC4J components for OAF and OA Page which holds the DFF I will explain the steps in detail below. Register the custom table in Oracle Application I am using custom DFF here so I have to register the custom table which I am going to capture the values.Please click here to see the table script. I am using the AD_DD package to register the custom table.Please click here to see the table registration script. Please verify the table has registered successfully. Navigation: Application Developer > Application > Database > Table Table has registered successfully. Register the DFF Next step is to register the DFF. Navigate to Application Developer > Flex Field > Descriptive > Register. Give details as below. Click on Reference Fields and set the Reference Field as ATTRIBUTE_CATEGORY. Click on the Columns button to verify that the columns ATTRIBUTE_CATEGORY,ATTRIBUTE1 .... ATTRIBUTE30 are enabled. DFF has registered successfully. Define the segments of DFF Here I am going to define the segments of the DFF.Navigate to Application Developer > Flex Field > Descriptive > Segments.Query for "XXCUST - Person DFF". Uncheck "Freeze Flexfield Definition". In my DFF the reference field I want to display a value set which has values "Permanent" and "Contractor". So define a value set  XXCUST_EMPLOYMENT_TYPE. Navigation: Application Developer > Flex Field > Descriptive > Validation > Sets After that assign the values to above created value sets. Navigation: Application Developer > Flex Field > Descriptive > Validation > Values Assign XXCUST_EMPLOYMENT_TYPE to Context Field Valueset. Setup the Context Field Values based on below table. Context Code Segments Global Data Elements Phone Number Email Fax Contractor Manager Extension Number CSP Name Permanent Extension Number Access Card Number Phone Number,Email and Fax displays always.When user choose Context Value as "Contractor" Manager Extension Number and CSP Name will show.In case of "Permanent" Extension Number and Access Card Number will show.  Assign value set also as follows. For Global Data Elements following are the segments. For "Contractor" following are the segments. For "Permanent" following are the segments. Check the "Freeze Flexfield Definition" check box and save.Standard concurrent program "Flexfield View Generator" will generate XXCUST_DFF_DEMO_DFV view which we mentioned in the DFF registration step.  Now the DFF has created successfully and ready to use. Create BC4J components for OAF and OA Page which holds the DFF Create the BC4J components ( EO,VO and AM) appropriately.Create the page based on the created VO.For DFF create an item of type "flex" with following property.  Note: You cannot create a flex item directly under a messageComponentLayout region, but you can create a messageLayout region under the messageComponentLayout region and add the flex item under the messageLayout region. In the Segment List property give the segment names which you want to display.The syntax of this is Global Data Elements|SEGMENT 1|...|SEGMENT N||[Context Code1]|SEGMENT 1|...|SEGMENT N||[Context Code2]|SEGMENT 1|...|SEGMENT N||... Eg: Global Data Elements|Phone Number|Email|Fax||Contractor|Manager Extension Number|CSP Name||Permanent|Extension Number|Access Card Number When you change the Context Value corresponding segments will display automatically by PPR in the page. You can attach partial action to the DFF bean programmatically so that you can identify the action related to DFF. pageContext.getParameter(EVENT_PARAM) will return "FLEX_CONTEXT_CHANGEDPersonDFF" when you change the DFF Context. Page is ready and you can test. When you choose "Contract" following output you can see. When you choose "Permanent" following output you can see.  Give proper values and press Apply.You can see values populated in the table.

  • Async CTP (C# 5): How to make WCF work with Async CTP

    - by javarg
    If you have recently downloaded the new Async CTP you will notice that WCF uses Async Pattern and Event based Async Pattern in order to expose asynchronous operations. In order to make your service compatible with the new Async/Await Pattern try using an extension method similar to the following: WCF Async/Await Method public static class ServiceExtensions {     public static Task<DateTime> GetDateTimeTaskAsync(this Service1Client client)     {         return Task.Factory.FromAsync<DateTime>(             client.BeginGetDateTime(null, null),             ar => client.EndGetDateTime(ar));     } } The previous code snippet adds an extension method to the GetDateTime method of the Service1Client WCF proxy. Then used it like this (remember to add the extension method’s namespace into scope in order to use it): Code Snippet var client = new Service1Client(); var dt = await client.GetDateTimeTaskAsync(); Replace the proxy’s type and operation name for the one you want to await.

  • Syntax Recognition for XML-Based Languages in Oracle JDeveloper

    - by Ramkumar Menon
      @Thanks Jeffrey Stephenson If you are looking at using any one of the new XML Based languages, lets say a docbook xml, or xproc, or what not, you can make use of JDeveloper's syntax highlighting and completion insight feature to ease out those extra keystrokes. All you need is a URL/local copy of the XML Schema for the language. Once you have, you can register it via Tools --> Preferences --> XML Schemas.   Remember to provide a new extension name [Using a default .xml extension did not work for me.] I provided my own extension .dbk for my docbook files. Once you save these settings, you can create new files that conform to the schema, and you get validation/completion insight/prompting for free.

  • How to use Xvfb in Ubuntu 14.04 with/without RandR?

    - by Itchy
    I try to run Unit-Tests with Selenium running Firefox on my Ubuntu 14.04 Server. And I'm using Xvfb as described in this blog to simulate a virtual display to show Firefox in. But Xvfg somehow doesn't load/work with RandR. Because whenever I try this: sudo Xvfb :10 -ac & export DISPLAY=:10 firefox I get an Xlib: extension "RandR" missing on display ":10"-Error. I've also tried sudo Xvfb :10 -ac +extension RANDR, sudo Xvfb :10 -ac -extension RANDR and beacuse it supplies with "xrandr" also apt-get install x11-xserver-utils. And my setup is a plain empty Ubuntu 14.04 Server with apt-get install xvfb firefox. Can anyone please help me run Xvfb with or without RandR?

  • View Docs and PDFs Directly in Google Chrome

    - by Matthew Guay
    Would you like to view documents, presentations, and PDFs directly in Google Chrome?  Here’s a handy extension that makes Google Docs your default online viewer so don’t have to download the file first. Getting Started By default, when you come across a PDF or other common document file online in Google Chrome, you’ll have to download the file and open it in a separate application. It’d be much easier to simply view online documents directly in Chrome.  To do this, head over to the Docs PDF/PowerPoint Viewer page on the Chrome Extensions site (link below), and click Install to add it to your browser. Click Install to confirm that you want to install this extension. Extensions don’t run by default in Incognito mode, so if you’d like to always view documents directly in Chrome, open the Extensions page and check Allow this extension to run in incognito. Now, when you click a link for a document online, such as a .docx file from Word, it will open in the Google Docs viewer. These documents usually render in their original full-quality.  You can zoom in and out to see exactly what you want, or search within the document.  Or, if it doesn’t look correct, you can click the Download link in the top left to save the original document to your computer and open it in Office.   Even complex PDF render very nicely.  Do note that Docs will keep downloading the document as you’re reading it, so if you jump to the middle of a document it may look blurry at first but will quickly clear up. You can even view famous presentations online without opening them in PowerPoint.  Note that this will only display the slides themselves, but if you’re looking for information you likely don’t need the slideshow effects anyway.   Adobe Reader Conflicts If you already have Adobe Acrobat or Adobe Reader installed on your computer, PDF files may open with the Adobe plugin.  If you’d prefer to read your PDFs with the Docs PDF Viewer, then you need to disable the Adobe plugin.  Enter the following in your Address Bar to open your Chrome Plugins page: chrome://plugins/ and then click Disable underneath the Adobe Acrobat plugin. Now your PDFs will always open with the Docs viewer instead. Performance Who hasn’t been frustrated by clicking a link to a PDF file, only to have your browser pause for several minutes while Adobe Reader struggles to download and display the file?  Google Chrome’s default behavior of simply downloading the files and letting you open them is hardly more helpful.  This extension takes away both of these problems, since it renders the documents on Google’s servers.  Most documents opened fairly quickly in our tests, and we were able to read large PDFs only seconds after clicking their link.  Also, the Google Docs viewer rendered the documents much better than the HTML version in Google’s cache. Google Docs did seem to have problem on some files, and we saw error messages on several documents we tried to open.  If you encounter this, click the Download link in the top left corner to download the file and view it from your desktop instead. Conclusion Google Docs has improved over the years, and now it offers fairly good rendering even on more complex documents.  This extension can make your browsing easier, and help documents and PDFs feel more like part of the Internet.  And, since the documents are rendered on Google’s servers, it’s often faster to preview large files than to download them to your computer.

  • Python C API return more than one value / object

    - by Grisu
    I got the following problem. I have written a C-Extension to Python to interface a self written software library. Unfortunately I need to return two values from the C function where the last one is optional. In Python the equivalent is def func(x,y): return x+y, x-y test = func(13,4) #only the first value is used In my C extension I use return Py_BuildValue("ii",x+y,x-y); which results in a tuple. If I now try to access the return value from Python via test2 = cfunc(13,4) print(test2) I got a tuple instead of only the first return value. How is possible to build the same behavior as in Python from C Extension?

  • Self Documenting Code Vs. Commented Code

    - by Phill
    I had a search but didn't find what I was looking for, please feel free to link me if this question has already being asked. Earlier this month this post was made: http://net.tutsplus.com/tutorials/php/why-youre-a-bad-php-programmer/ Basically to sum it up, you're a bad programmer if you don't write comments. My personal opinion is that code should be descriptive and mostly not require comment's unless the code cannot be self describing. In the example given // Get the extension off the image filename $pieces = explode('.', $image_name); $extension = array_pop($pieces); The author said this code should be given a comment, my personal opinion is the code should be a function call that is descriptive: $extension = GetFileExtension($image_filename); However in the comments someone actually made just that suggestion: http://net.tutsplus.com/tutorials/php/why-youre-a-bad-php-programmer/comment-page-2/#comment-357130 The author responded by saying the commenter was "one of those people", i.e, a bad programmer. What are everyone elses views on Self Describing Code vs Commenting Code?

  • Favorite Visual Studio 2010 Extensions

    - by Scott Dorman
    Now that Visual Studio 2010 has been released, there are a lot of extensions being written. In fact, as of today (May 1, 2010 at 15:40 UTC) there are 809 results for Visual Studio 2010 in the Visual Studio Gallery. If you filter this list to show just the free items, there are still 251 extensions available. Given that number (and it is currently increasing weekly) it can be difficult to find extensions that are useful.

  • Unable to change the launcher icon size

    - by takeshin
    After upgrading to 11.10 I can't change the launcher icon size to smaller. I've tried to change it using ccsm, like described in How can I configure Unity, but the changes take no effects (restarted, tried sudo - still big icons). In the previous version of Ubuntu this solution worked. How can I change the icon size? (BTW, how can I know which Unity (2D vd 3D) I'm running and switch between?). Edit: Looks like I'm using Unity 2D and have some problems with graphics: me@my-laptop ~ $ /usr/lib/nux/unity_support_test -p Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0".

  • Text Editor with SSH/Terminal/FTP/Putty combo for develeping in Rails on Windows

    - by Panoy
    I plan to learn Ruby on Rails and would like to code in my development box which runs on Windows XP. I have Ubuntu Server (forgot the version ;p) running as my web server with Rails installed on it. I have been considering using Vim as my text editor of choice in XP but would like to know any text editor and accompanying shell/FTP/Putty/SSH (or whatever you may call it) program that can access those files in my Ubuntu server. It is better if the shell can be called or is bundled inside the text editor. I would like to know your combinations (text editor + shell) and your experiences on it when you were able to develop your Rails projects on that combination. Cheers!

  • Revert F3 and F4 behavior in byobu?

    - by James Zimmerman II
    With a fresh 12.04 installation of Ubuntu, byobu's interpretation of the function keys seems to have changed. F3 and F4 will still change the active tab on the current session, but it changes it for all connections. Previously, if you have two active connections to the same user (same session) with User 1 on shell 0/tab 0 and User 2 on shell 0/tab 0, when User 2 pressed F3 , they would be changed to tab 1 while User 1 would remain on tab 0. With the latest version in 12.04, when User 2 presses F3, all connected users are moved to shell 1/tab 1. Is there any way to re-enable the old behavior? I have looked at the /etc/byobu directory and only found backend and socketdir files there. Toggling backend between tmux and screen did not seem to render any difference. Anyone know what, if any, configuration option exist to control this?

  • LibreOffice english spelling dictionary missing

    - by rossouwap
    I've got two machines, same OS (Ubuntu 11.10 x86_64), same LibreOffice ppa's (ppa:libreoffice/ppa). One has the "English spelling dictionaries, hyphenation rules, thesaurus..." extension in the extension manager, the other doesn't. Each upgraded using the ppa from 3.5.0 to 3.5.1. Can anyone provide some insight as to how to get this extension onto the second machine? I can remove LibreOffice from the second machine and install the packages from the LibreOffice site, but would prefer to keep the ppa - as I don't then need to remember to upgrade.

  • How to remove Launchpad app/webapp?

    I was browsing Launchpad and it asked to install a helper app. I thought that this was the Firefox extension so I said yes. Now I have this launcher app that will open a Firefox window directly to Launchpad from my unity dash. I want to remove it and I can't. I removed the Firefox extension and it's still there. I removed the Unity webapps Firefox extension and it's still there. I tried to purge "launchpad" and my system says that it doesn't exist. I searched Launchpad for information on this app but found nothing I could understand that seemed to be relevant. But it's still there, staring at me from the Unity dash. Can anyone help me get this thing out of my system? Running Ubuntu 13.10

  • Preventing Duplicates on Google

    - by abel
    I am currently using a rewrite rule to enable access to .php pages, without using the php extension. However to prevent old links from breaking, the pages can still be accessed via links containing the .php extension too. For eg. domain.com/page.php can now be accessed at domain.com/page All the links on the website now use domain.com/page type links within the site. However older incoming links will still link to the .php pages, meaning Google will index both pages and mark them as duplicate. I have two plans to remedy the situation. Use a php 301 redirect: When a page is accessed with the .php extension, I can redirect each page individually using a 301 redirect using php Using Canonical: Place a canonical tag on each page, pointing to the ".php" less version My Question: Are both methods equally efficacious in preventing Google from indexing my ".php" pages? Which method should be preferred, by convention or otherwise?

  • Application compatability with the Cinnamon Desktop

    - by fossfreedom
    I've reading about about the Cinnamon Desktop through this Q&A: How do I install the Cinnamon Desktop? I've also been looking at the various possible various flavours of Ubuntu such as Unity/Gnome-shell and KDE: How do I install KDE shell on Ubuntu? How do I install and use the latest version of GNOME Shell? My concern is about running applications on Cinnamon - I'm fairly new to linux and am unsure about running software - especially about potentially mixing different software that may have been targeted at different desktops. Can I run a Kubuntu or Unity applications in Cinnamon or do I have to get specific Cinnamon only applications? For example, KOffice/Libreoffice, Okular/evince etc. Any help understanding what potential impacts such as extra software I may need to use or additional configuration to make sure that various different software behave and look like each other would be gratefully received.
