I am creating a live CD for use in a kiosk/installation. The main reason is to prevent a conventional hard drive from becoming corrupted in an environment with lots of power interruptions--in fact I can tell the staff there to simply flick off a light switch at the end of the day and feel confident that it will come back reliably in the morning.
I am using uck to install the nvidia drivers, the application my team is creating, and the like. So far, all is working well, except for one thing: the screens turn off after 5 minutes. As I understand it, the system settings for all this are set by the default dconf profile. I can't just change the settings for the root user in the uck terminal; user "ubuntu" is created from scratch on every boot. I need to change the default profile.
I did some digging and found the dconf key that I want to provide a new default for is idle-delay.
I tried to follow the instructions on the dconf wiki page, but it's pretty confusing to me. I also tried to follow the instructions here for setting the idle-delay, without success.
My question is: what are the correct files to create, and/or commands to run, to specify in the dconf db that every new user should start out with a profile that leaves the monitor on all day?
/org/gnome/desktop/session/idle-delay appears to be the key I want to set.
Thank you kindly!
