The OS Ubuntu 12.10 is installed on my computer. I want my computer never locks the monitor's screen. So that I chose the item "never" in the option "Lock the screen after...". But it doesn't work. What should I do to improve it?

If it's the same problem I had it's xscreensaver timeout being set to 6000 that's the problem.

Try running xset s 0 0 from the command line, this fixed the problem for me.

Open system settings and select brightness and lock

Slide the button below Lock to off.

I did it. It doesn't work. – Yuriy Dyadkin Jan 9 '13 at 12:38

I had the same problem a while ago and found the solution by running the following command in terminal:

xset s off -dpms

This will disable the screensaver and the display power management.

You can put it in Start-up Programs if you want.
