I live far away from my mother. When her old laptop on windows XP died, I replaced it by a minicomputer with ubuntu gnome (14.04) that I remotely administer (ssh, x11vnc and rsync for backups). As old windows xp users, she has many icons on her desktop. I have created some launchers (firefox.desktop, thunderbird.desktop, Word.desktop (for libre office writer)).
Regularly, she calls me because one of these launchers has disappeared. Each time I find the missing launcher in the trash folder. Probably a mistake of my mother.
How would you protect these launchers while leaving write permission to Desktop folder ? Should I write a cron to monitor these mistakes ?
One idea is to put the sticky bit on the desktop folder and change the owner of the folder and .desktop files to root. Are there nasty side effects to be expected ?
It may not be the answer you're looking for, but maybe you could teach her how to restore the file from trash? – gronostaj – 2018-01-31T09:23:19.620
Yes, but she is 80 and she has already difficulties with thunderbird. I try to teach her how to watch pictures, but she often get lost. – Jean-Francois Bocquet – 2018-01-31T14:14:45.237
