I have a Dell Precision workstation T7400 with Ubuntu 14.04 LTS installed with Gnome Classic Desktop. I usually lock the workstation which can be unlocked if it is locked for a few hours. But if I leave it overnight, the next day the workstation seems to be in possibly a suspended state. The keyboard lights are on, but the mouse or keyboard remains inactive. Powering on the machine also does not respond, the whole workstation is in a frozen state. I have a couple of questions regarding this issue. In the power settings tab, "Don't suspend" is already checked.
- Does Ubuntu 14.04 have automatic suspend option and what is the time required for automatic suspending?
- How to prevent this from happening? I don't want the workstation to sleep at all.
