Ubuntu 20.04.1: In Preferred Applications for Mate, in the Office tab, I change the Document Viewer to Atril Doc viewer but it never stays. It changes back to ImageMagick as soon as I close it. This is very annoying as I can't just click on a doc and have Atril open it. ImageMagick splash page opens. But it rarely if ever opens the document. I don't want it to either.
I need to keep ImageMagick because I use the Term commands it supplies all the time. I take thousands of pictures every year and using Term, bulk resize them using Mogrify command. If I uninstall ImageMagick, that command disappears with it.
How do I get ImageMagic to NOT be persistant? If this isn't where I should be asking this, let me know.
