PDF book opens in Mendeley when openned from Calibre

  • 772

I have Ubuntu Gnome installed and I am using i3wm. Everytime I double click a book in Calibre to open it it opens in Mendeley desktop.

This doesn't happen under Gnome.

Could you explain why this happens and how I can fix it?

  1. The problem seems to be that xdg-open is misconfigured:

    $ xdg-mime query default application/pdf
mendeleydesktop.desktop

    Sure enough, if I run xdg-open some.pdf it opens with Mendeley. It seems that some applications use xdg-open while others don't.

    According to this, the culprit should be in here:

    $ cat /usr/share/applications/mimeinfo.cache | grep pdf
application/pdf=evince-previewer.desktop;gimp.desktop;evince.desktop;mendeleydesktop.desktop;
application/x-bzpdf=evince-previewer.desktop;evince.desktop;
application/x-ext-pdf=evince-previewer.desktop;evince.desktop;
application/x-gzpdf=evince-previewer.desktop;evince.desktop;
application/x-xzpdf=evince-previewer.desktop;evince.desktop;
image/pdf=display-im6.q16.desktop;display-im6.desktop;

    Looks good to me, except GIMP being there; oh well.

    $ cat .config/mimeapps.list | grep pdf
application/pdf=evince.desktop;inkscape.desktop;

    Looks fine as well. So the problem could be in an i3-specific config file. But:

    $ echo $XDG_CONFIG_DIRS
/etc/xdg/xdg-i3:/etc/xdg

    The former folder does not exist, and the second does not contain any .list file.

    So I have no idea where this comes from. But running

    xdg-mime default evince.desktop application/pdf

    does certainly fix it.
