If you’re using Ubuntu 14.04, there’s a good chance that you’re using the Linux kernel version 3.14.0-desktop-1ubuntu4. This release includes a new feature called “online content fetching.” This feature allows the kernel to automatically request pages from websites when it starts up, and then store those pages in memory so that they can be accessed when needed. If you disable this feature, your computer will not be able to access any of the pages stored in memory by the kernel, and you’ll likely experience some problems with website access and browsing. To disable online content fetching in Ubuntu 14.04, open a terminal and type: sudo add-apt-repository ppa:ubuntu-kernel/ppa sudo aptitude remove -y onlinecontentfetching
To do this, press Ctrl + Alt + T to open a Terminal window. Type the following command at the prompt and press Enter.
NOTE: Linux is case sensitive, so you must type the line above as shown. Also, when we say to type something in this article and there are quotes around the text, DO NOT type the quotes, unless we specify otherwise.
If you are returned to the prompt with no further messages, the command was successful. Type “exit” at the prompt to close the Terminal window.
For this setting to take effect, you must log out and then log back in. To do this, select Log Out from the system menu on the top panel in the upper-right corner of the screen.
You can either lock the screen or log out. Click Log Out.
Once you log back in, click the Search button at the top of the Unity bar to access Unity Dash. Type a search term in the search box. Notice that the results displayed are only applications and files and folders found locally on your computer. There are no remote results.
If you decide you want the remote results again, type the following command at the prompt in a Terminal window and press Enter.
With no remote sources included in your searches, the search results should display faster.
