    How to Install / Upgrade Nvidia 319.49 in Ubuntu 13.04, 12.04, 12.10

    Last updated: August 26, 2013

    The latest Long Lived Nvidia driver has reached 319.49, which added support for new GPUs and fix a few bugs. Here’s how to install or upgrade it in Ubuntu 13.04, Ubuntu 12.10, Ubuntu 12.04.

    What’s new in Nvidia 319.49:

  • Added support for the following GPUs: GeForce GT 740A, GeForce GT 745A, GeForce GT 755M, GeForce GT 625, GeForce GTX 645, GRID K340, GRID K350, NVS 315, Quadro K500M
  • Fixed a bug that caused DisplayPort monitors connected to Quadro FX 3800, 4800, or 5800 to remain off after DPMS.
  • Added the NVIDIA OpenGL-based Inband Frame Readback (NvIFROpenGL) library to the Linux driver package. This library provides a high performance, low latency interface to capture and optionally encode an individual OpenGL framebuffer. NvIFROpenGL captures pixels rendered by OpenGL only and is ideally suited to application capture and remoting.
  • Fixed a bug that caused applications using CUDA-GL interop to crash when run on X servers with Xinerama enabled.
  • Fixed a bug that could prevent some double-bit ECC errors from being properly reported.
  • Fixed a bug which could cause a blank screen when changing house sync settings on Quadro Kepler GPUs with Quadro Sync boards.
  • Fixed a bug that prevented nested loops with identical loop conditions in GLSL shaders from terminating correctly. This could cause hangs in applications such as Exa PowerVIZ.
  • Fixed a bug that resulted in corrupt texels when a previously empty texture image was specified with glXBindTexImageEXT. In GNOME 3, this caused gnome-screenshot to produce garbled window screenshots.
  • Fixed a bug that caused the X server to crash when querying the current mode of disabled displays.

    • Download & Install Nvidia Driver:

    TVPVRD: Advanced Digital TV Recorder for Ubuntu Linux

    Last updated: April 4, 2019

    TVPVRD is a highly flexible and configurable server daemon that acts as an advanced digital TV recorder using one or several installed TV capture cards.

    The server manages scheduled recordings and provides an efficient command language interface on a dedicated TCP/IP port. As an alternative interface the daemon also comes with a basic WEB-interface through the daemons built in micro-web-server. To keep the WEB-interface simple only the most common commands are available through this interface.

    The goal with this project is to provide an advanced recording and transcoding (using ffmpeg) server without the need to configure complex databases or GUI. The daemon sits unobtrusively in the background.

    The server is self-contained and uses a plain text database (in XML format) to store and manage recordings. In addition, the server has built-in intelligence to make it as easy as possible to manage and use. Examples are highly flexible commands to specify future recordings and automatic load assessment on the server to avoid starting too many parallel transcoding jobs. The server is completely self-contained and has a small footprint.

    Install TVPVRD in Ubuntu:

    The GetDeb repository provides the latest packages for Ubuntu 13.04 Raring, Ubuntu 12.04 Precise, and a little old versions for Ubuntu 12.10, Ubuntu 11.10 and their derivatives, such as Linux Mint and Elementary OS.

    To Add GetDeb repository, just download and double-click to install the package below (For Linux Mint users, read this post).

    getdeb package

    Once done, install TVPVRD by running below commands in terminal (Ctrl+Alt+T):

    sudo apt-get update; sudo apt-get install tvpvrd

    Use TVPVRD:

    There are two main ways to use tvpvrd:

    1. via command line shell, run man tvpsh to get details
    2. via the built in Webserver (http://localhost:9301/)

    You need to enable the config file by running below command:

    cd /etc/tvpvrd; sudo mv tvpvrd.conf.full.template tvpvrd.conf

    Then edit the file by:

    sudo gedit /etc/tvpvrd/tvpvrd.conf

    There you can change the port, enable web interface by “enable_webinterface=yes” and many other settings.

    For more, see tvpvrd manual.

    Install Adobe’s Brackets Editor in Ubuntu and Derivatives

    Last updated: March 21, 2019

    As you may know, Brackets is an open-source editor for web design and development built on top of web technologies such as HTML, CSS and JavaScript. The project was created and is maintained by Adobe, and is released under an MIT License.

    What makes Brackets different from other web code editors?

  • Tools shouldn’t get in your way. Instead of cluttering up your coding environment with lots of panels and icons, the Quick Edit UI in Brackets puts context-specific code and tools inline.
  • Brackets is in sync with your browser. With Live Development, Brackets works directly with your browser to push code edits instantly and jump back and forth between your real source code and the browser view.
  • Do it yourself. Because Brackets is open source, and built with HTML, CSS and JavaScript, you can help build the best code editor for the web.

    • Try out Brackets:

    The official download page provides the DEB packages for Debian / Ubuntu and their derivatives, such as Linux Mint, Elementary OS, and so forth.

    Just download and double click the DEB to bring up Ubuntu Software Center and install it. Or run below commands instead once downloaded:

    sudo dpkg -i ~/Downloads/brackets-sprint-*.deb; sudo apt-get -f install

    Once installed, you can find it in Unity Dash.

    Use Silverlight in Firefox, Chrome in Ubuntu via Pipelight plugin

    Last updated: March 21, 2019

    Pipelight is a special browser plugin allows to run your favorite Silverlight application directly inside your Linux browser. The project combines the effort by Erich E. Hoover with a new browser plugin that embeds Silverlight directly in any Linux browser supporting the Netscape Plugin API.

    Pipelight consists out of two parts: A Linux library which is loaded into the browser and a Windows program started in Wine. The Windows program, called pluginloader.exe, simply simulates a browser and loads the Silverlight DLLs. When you open a page with a Silverlight application the library will send all commands from the browser through a pipe to the Windows process and act like a bridge between your browser and Silverlight. The used pipes do not have any big impact on the speed of the rendered video since all the video and audio data is not send through the pipe. Only the initialization parameters and (sometimes) the network traffic is send through them. As a user you will not notice anything from that “magic” and you can simply use Silverlight the same way as on Windows, like you can see on the following screenshot:

    Install Pipelight on Ubuntu

    Warning: Before you continue the installation you should note that:

  • It is strongly recommended to close your browser before installing! Some browsers try immediately to load the plugin which might fail or crash the browser when the installation is not complete!
  • Silverlight might contain (like all other browser plugins) security issues – You may want to enable click-to-play for this plugin to prevent an undesired start of Silverlight.
  • Pipelight needs to start Wine to execute the pluginloader. This may slow down the start of your browser.

    • The Pipelight PPA is available for Ubuntu 13.10, Ubuntu 13.04, Ubuntu 12.10, Ubuntu 12.04 and their derivatives. You can easily install it by running below commands in terminal (Ctrl+Alt+T) one by one:

    sudo add-apt-repository ppa:pipelight/stable
sudo apt-get update
sudo apt-get install pipelight

    You may need to accept a license agreement for a set of fonts during the installation. After it’s done just start your browser, type about:plugins in the addressbar and hit enter – if the installation went well you should now see Silverlight in your plugin list and everything is ready to run! Pipelight will install Silverlight on the first start of your browser, this may freeze the interface for several minutes (and you may just see a blank page without any progress). There might appear some dialog asking if Mono or Gecko should be installed during the Silverlight installation – you can safely choose no, as this is not necessary to get Pipelight running. After this step, the overall performance of your browser shouldn’t be affected any more.
