Can you clarify your question a little bit? Normally locking works exactly as you described. –  Danatela Apr 28 at 4:24
    
No in normal locking, the download gets stopped. I just want any normal user to prevent access my desktop. –  ray Apr 28 at 4:27
    
What download? Wget? D4a? –  Danatela Apr 28 at 4:28

I suspect you did a logout rather lock screen, which could be why download was stopped. –  Jay Aurabind Apr 28 at 4:30

There is no need for third-party software to lock your desktop on Windows: just use Windows Key + L. –  neon_overload Apr 28 at 5:27

On Ubuntu (with the default desktop settings), locking the desktop is done with Ctrl + Alt + L.

Edit: I believe Super + L works too in recent versions of Ubuntu, which is the same as in Windows.

No additional software is required.

This will not halt or pause any software. Downloads should continue as normal.

Default Lock option must do the trick, but if you want a simple alternative, use slock

sudo apt-get install suckless-tools

You can lock by simply invoking slock at any terminal, or by binding it to a keyboard shortcut. To unlock, simply activate your display (if it got turned off), and blindly type in your password.

Note that there will not be any sort of indication of echo back of the password you type. You will see a plane blue screen. Type the password and hit enter to unlock.

I love all the suckless tools. I use them pretty frequently! –  Rob Apr 28 at 17:37

To invoke a "lock" from the command line, you can accomplish this with gnome-screensaver-command -l, based on this Q/A: How do I lock the screen from a terminal?

However, for a "clear" locking solution you can try xtrlock.

sudo apt-get install xtrlock

Then you can invoke it from a terminal:

xtrlock

This will allow you to continue to view the desktop, while remaining locked. To unlock it, just type your password.

Note: I was confused by this at first, because it never presents you with a dialog or prompt to enter your password. You just start typing it, and it unlocks when you hit Enter.
