I have an application that will render files with a .hpgl suffix.
I have a HPGLplotter.desktop file in /usr/local/share/applications/ that has the line …
MimeType=application/vnd.hp-hpgl;
however I don’t see the application in the Nautilus “Open With” dialog. When I double click on a file with suffix .hpgl I get the dialog with the message “There is no app installed for “HPGL file” files. Do you want to search for an app to open this file?”. When I search, I get the message “Unable to find the application/vnd.hp-hpgl file format you were searching for.”
How do you tell Nautilus how to open this mimetype?
Also, a few applications seem to be spamming the open file dialog (Okular and Krita particularly). Is there a way to fix this without uninstalling the program?
