How do you change the default document viewer to Okular?

  • 772

I have just started using Okular and I love it. It has a lot of functionality that I need when I am in pdfs and it already opens up epubs automatically. How to I get it to open pdfs by default instead of "Document Viewer?"

I appreciate the help!

okular

    According to here, Right click the file of the format you want, select properties:

    Go to the open with tab, select the program you want to be the default for that type of file, then press the button Set as Default:

  2. Well, none of the other answers worked on 14.04, Okular simply doesn't show up in the list. But this worked perfectly:

    mimeopen -d myfile.pdf

    It will give you a list of applications that can open the file, and will also update the default application for you. 

    $ mimeopen -d myfile.pdf
Please choose a default application for files of type application/pdf

1) Print Preview  (evince-previewer)
2) Xournal  (xournal)
3) MuPDF  (mupdf)
4) Adobe Reader 9  (AdobeReader)
5) GIMP Image Editor  (gimp)
6) Document Viewer  (evince)
7) Other...

use application

    Selecting one of these will set it as the default for application/pdf file types. You can easily set any executable to be the default by using the Other... option:

    use application #7
use command: okular
Opening "myfile.pdf" with usr (application/pdf)

    Aside: If okular doesn't work, you might want to try entering the full path (usr/bin/okular). You can find out where Okular is located by running which okular.

  3. In Ubuntu 14.04, the file you need to edit is :~/.local/share/applications/mimeapps.list

    The name of okular may varies. Someone may also find that there is no "Set as default" button.

    So follow these steps:

    Step 1: Right click on any pdf file => Open with => find Okular

    The name of okular applications now should be specified in mimeapps.list. Now move to step 2.

    Step 2: gedit ~/.local/share/applications/mimeapps.list

Step 3: Find okular in [Added association] and copy to [Default application] section.
In my case, it is 'application/pdf=kde4-okularApplication_pdf.desktop;'

    And you are done.

  4. First open a terminal and use this command:

    gedit ~/.local/share/applications/defaults.list

    After opening it, Under the [Default Applications] section add a line like this

    application/pdf=okular.desktop;

    Now save the file and exit gedit.

  5. In short, if I remember correctly :

    • Right click on a PDF,
    • Properties,
    • Open with,
    • Select an app,
    • Set as default.
