Hey Guys Try this work around, It's the only one that worked on my Toshiba NB505 With realtek drivers...

Settings> security & privacy> Uncheck waking from Suspend & Returning From blank screen

Delete the entire contents of the following files "/etc/pm/config.d/config" & "/etc/pm/config.d/unload_modules"

gksu gedit /etc/pm/config.d/config
gksu gedit /etc/pm/config.d/unload_modules

Try a suspend and it should come back.... That said you might want to look around for more edited files in /etc/pm/config.d/

Having said all that I have no Idea why that works. lol
