Running a program in the background as sudo

I am on a linux virtual machine and I'm trying to run the command sudo synaptic & which should start synaptic in the background. However, it doesn't ask for the password and the program doesn't seem to start. I have not typed my password earlier, as running any other command withouth the & at the end ask for my password. What is the problem?

From the previous answer, only adding -b to a command starting with sudo might work, as below:

sudo -b COMMAND

Worked for the command below:

sudo -b mongod --config /etc/mongod.conf

Note. For a non-sudo command, there's nohup, as below:

nohup COMMAND &

Adding nohup before the command, and an & after the command might work for a non-sudo command.

sudo --help says about option -b

-b, --background              run command in the background

This worked for me

sudo -b su -c "command what you want to run"

You can run sudo bash -c 'synaptic &'

The problem is that the sudo command itself is being run in the background. As a result, it will be stopped (SIGSTOP) when it tries to access the standard input to read the password.

A simple solution is to create a shell script to run synaptic & and then sudo the script in the foreground (i.e. without &).
