    Live USB Ubuntu (screen?) fails to restart after suspend

    Hello All-
    I have a laptop that I can't install a hard drive in - a connector is broken of some sort.

    All else works well & has a great battery life, so I am using a live usb with persistence with the laptop.

    All is good enough except for suspend.

    Here's the scenario:
    Choose suspend
    Laptop suspends
    Press a button
    Things happen (fan whirs, some lights come on- looks/sounds/smells as if it is on
    Screen is black/not on
    I try 8000 keystroke combinations to wake it
    Nothing works
    I press and hold power button to shut it off

    To clarify about the screen being "black/not on"-
    it's black- definitely not back lit
    I have left it alone in that state for over 20 minutes with no change

    I have searched the forums and tried a couple of solutions proffered for others in similar situations with no love (stuff about killing the xserver and a couple of esoteric to me bits with startup scripts- it was a scattershot attempt that I've lost the references too (I apologize for that))

    One detail that seemed different in my case is that I am running a live usb with persistence- pretty much all the other cases involved regular old hardrive installed ubuntu.

    So, one question for experts I have is- is a live usb ubuntu with persistence (running on a laptop) capable of suspending? Does the usb nature or persistence mess stuff up?

    All other input welcome.

    I honestly don't know if a persitent USB installation has a swap file or not, and I think the type of suspend or hibernate you are talking probably requires a swap file larger than the physical memory size.
