I know this question has been asked before here, but that solution didn't worked for me.
I have some quite weird requirements, I need to prevent the process of changing wallpaper in Ubuntu. What I would not want to do is have some python script run as daemon process which periodically changes wallpaper.
I want to make sure that nobody can change wallpaper without writing that particular password. According to the linked post, you need to change a file located at /usr/bin having the name gsettings. I followed the same process as described, and successfully changed the content of that file, but nothing seems to happen.
How can I password protect changing the wallpaper?
I am using Ubuntu 19.10.
