Firstly, i should say I'm an elementary os newbie.So I'm really sorry if my question is too basic, pretty please please be patient with me, I'd really appreciate your help. I installed Elementary OS Freya 2 weeks ago, my first Linux based operating system. I had the usual pictures icon down on my desktop, but i was "smart" enough to try to install a program called "gnome wallpaper slideshow". I got a warning that it gets into conflict with an already existing program or something like that (i think with the embedded photo viewer) but i ignored that warning and installed the program anyway. Now, when I try to open a .jpg (right click-open with...) i only get the option "create background slideshow, and when i click on it nothing happens. I'd like to uninstall this program but i can't seem to find it anywhere. I'd really appreciate your help. I would like to be able and see .jpg files just like it should usually work in Elementary OS. Thank you for your help!

go to the aplications menu (at the left of the top of your screen) and look for software center, from there you can install and uninstall a lot of things with just a click


You can use:

sudo apt remove *package-name*

You have to replace package-name with the name of the software you want to remove.


If you want a simple uninstall

$~sudo apt-get remove 'application_name'

Or you can use

$~sudo apt-get purge 'application_name'

to uninstall the application and all relative files.

It seems in your case like you changed the default application that reads .jpg files.
Go to > System Settings > Applications > Image Viewer
And choose the default elementaryOS image viewer Photo Viewer.

  • purge is better for me, since it can clean everythings Commented Dec 7, 2021 at 7:41
