How to set the length time before session times out due to inactivity?
I've just installed Ubuntu 10.04 and find that if I leave the machine for more than a couple minutes, it will automatically log me out. Instructions at other sites have indicated that session controls are to be found in System>Properties. But there is no Session in the list under Properties in Ubuntu 10.04. How can I control this feature so that I'm not having to constantly login every time I turn around? I've searched everywhere and can't find a solution.
