I am running Ubuntu 11.10/64 bit with Unity 3D on a Intel® Core™ i5-2400 CPU @ 3.10GHz × 4 computer.
I am currently trying to use texstudio as the default application for opening *.tex files, but I cannot change the default application associated with that file type. I tried to change it by right-clicking on a .tex-file, then "properties", "open with", "show other applications" but however, neither texmaker nor texstudio will appear in the programme list and oddly enough, there is no "add application" button anymore, to add an application to that list by hand. I tried to make an entry in my /home/my home folder/.local/share/applications/mimeapps/mimeapps.list, nothing happened, still opening the files with gedit.
Is there no way to change the list of "other applications" or add an default application programme manually, i.e. by editing some file?
Thanks for your help.
