So, when I installed Lubuntu 12.04 on my netbook, I chose to login automatically; no password.
I have my wife's grandson visiting soon (15 yrs old), and given his history of behavior from last year, I deem it necessary to enforce some computer discipline!
It was real easy to set parental control on my Windows laptop but Lubuntu doesn't seem to have that facility. I tried, using the "users and groups" category, to change the set-up to needing the password to gain access to the system. It won't let me do that. It will let me change the admin. password, but that's all.
Any ideas? Or do I have to reinstall?
Appreciate any info, thanks.
