Sometimes I leave my PC doing other stuff while running an upgrade or downloading big files, Syncing my Dropbox, or something like that. After 10mins or so, my screen is locked (which I like).

I just wanted to know if running processes or the Internet connection will be locked too when that happens. Because I don't want to do that stuff after I get back on my PC again.

And if that's the case (halted processes), Is there a way to keep processes / connection running while the screen is locked?

I am also facing the same issue. I think there has to be some option for this. – Ankit May 6 '13 at 14:54

My answer to your question is It should not.
As far as i have been using Ubuntu i have seen processes stopping only when it is told to do so (I use a rhythmbox plugin which stops playing msic when the screnn gets locked without that plugin the music goes on.). Also i do the same thing that you do i.e lock the screen and keep stuff for syncing, downloading etc but it has never happened that the process gets stopped.

Welcome!!! :) :) – Ashu May 6 '12 at 10:13

This is because the program terminates as the screen closes(the ubuntu way). You need to mention the services to go on by

screen your_program_name

you can close screen with crtl-a-d then reopen it later with screen -rx
