A pair of closely related gripes:
I created a template (deb11a-internet-dvm) and a DVM template (internet-disposable), and colored the latter orange. (The default DVM template is green, a color I’m not using anywhere else yet [it’s set aside for Windoze], so it will stick out like a sore thumb if it gets used by mistake.)
OK, ImageMagick is basically one of my least favorite pieces of software because you cannot zoom in it by simply grabbing the window border and stretching. If you do that, the damn thing will change the aspect ratio to match your new window size, distorting the image. That’s IF it doesn’t hang or crash as it resizes.
So I installed ristretto on the template mentioned above. Of course, if you “open in dvm” it goes to the preferred software, which is ImageMagick. Opening the “Default Applications” application, it shows ImageMagick the preferred software for dozens [edit: actually about 18, I had it confused with something else] of file types, and changing them all to Ristretto is tedious to say the least. (The best way to find them all is to sort by application, but then when you change one from ImageMagick to Ristretto, the window jump-scrolls to the Ristretto part of the list and you have to scroll back up. And then this process must be repeated every time I regenerate the template. Furthermore, it doesn’t stick when I create internet-disposable from deb11a-internet-dvm, and it must be done again there.)
So I decided to try uninstalling ImageMagick. I did so both on internet-disposable AND deb11a-internet-dvm. (sudo apt remove imagemagick.)
Images sent to the disposable machine STILL open in ImageMagick even though it’s not on that VM or it’s template or the template’s template by any test I can devise.
One thing more annoying than a crappy piece of software is a crappy piece of software that won’t go away. (Yes, I’m thinking of RealPlayer from 20 years ago.)
So one of a multitude of things–1) how is that even happening? 2) How can I stop it from happening so the system will presumably then fall back on Ristretto? 3) Failing that, is there a command line way to list all the mime preferences then alter them? [all of my searches point me to the generic stuff, which is apparently a different animal; if they mention file type tweaking at all, they invariably say to open the GUI based app.]
