I opened a JPEG file once with the HEX editor bless. Now Nautilus and GNOME in general have associated all JPEG files with bless. How do I get it to go back to eog (Image Viewer)?

I've tried enabling the Remember this application for [...] files checkbox in the Open With Other Application... menu but with no luck.


This is a known bug in your Ubuntu version. The bug report contains following workaround:

  • right click the file in question
  • select PROPERTIES all the way down in the popup menu
  • go to "open with" tab
  • select an application that should be used by default
  • profit every time you double click

(This has to be done only once per file type.)


While using Ubuntu Tweak, there is possibility to view all extensions associations.

Just click on the tab File types manager, and you'll see the associations and can change them.
