You need to stop all the screen lock and screensaver programs, or at
least some of them.  I have a laptop which I connect to using ssh and
it stays up 'for ever' if it's turned on.  It may also be in your
'power manager' settings.  I use xubuntu so the details may be
slightly different, but what I have is:-

In "Session and Startup" I have both "Screen Locker" and "Screensaver"
disabled (i.e. they don't autostart).

In my Power Manager settings under the following tabs:-

    System - System power saving - "When inactive for" is set to 'never'.

    Display - I blank the display after 13 minutes, put to sleep after
    14 minutes, switch off after 15 minutes. Thus I don't need any
    screensaver program to prevent screen burn.  Note this just turns
    off the display, not the computer.
