I had set the swap file at 0 size, at installation, so I cannot hibernate. However,my RAM should do for the "suspend" function(I think).But whenever I suspend my system, it just starts from the very beginning, I start Ubuntu through GRUB, and nothing I left open is resumed.Any suggestions or useful information about this?

sudo pm-is-supported --suspend

has no results(only switches line and shows prompt).

Suspend usually means "suspend to RAM", which is the case for Ubuntu –  l3dx Aug 15 '13 at 12:02
    
Nice to have that clarified.So now remains the core of the question-why suspending does not work. –  Noob Doob Aug 15 '13 at 12:04
    
What returns sudo pm-is-supported --suspend? Also, try forcing the system (save all your data first) with sudo pm-suspend, if it don't work, edit your question and add dmesg | tail and /var/log/pm-suspend.log. –  Braiam Aug 15 '13 at 12:06

Added the information.Samik: My case is not the one described, it's not I get a Black screen, it's that no suspending happens (system starts from zero) plus I will seek for another solution before trying a script. I wanna solve the core of the problem , not get past it. –  Noob Doob Aug 17 '13 at 11:59
