when the computer is locked (probably sleep mode) and i have to enter my password to log in, i see some programs that are running, or open. I am seeing Zorin connect, Fragments, snapd user agent and Backups. I use Zorin Connect so I know that has to be running, but I uninstalled Fragments and it still shows up. And I don't know what is snapd user agent and why Backups is running. How can i stop those programs from running, or should i let them run?
Have you rebooted since you uninstalled it?
Snap Daemon manages checking for updates to Snap Packages.
If you are not using any Snap Packages and do not plan to, you can remove snapd to remove that process clearing drive space, increasing boot time and conserving a little CPU or Battery:
sudo apt remove --purge snapd
Backups is Deja Dup/Duplicity and Backups can be scheduled. For this reason, it will run in the background in case there are Scheduled backups to create, even if the computer is in Sleep.
I have been using Zorin for the past two months and it was just three days ago I started to see these programs showing up on the login screen. Backups and Snap were not running since I installed Zorin?
Go to Settings>Notifications, there you can turn off all notifications or individual ones.
You can turn off notifications on the lock screen, then the programs you see now will no longer be shown.
Thanks
