Comment 1 for bug 449188

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage . I have classified this bug as a bug in gnome-power-management.

Although the system supports screen blanking (it works on time), it could also be a lower level issue, and in that case, I hope someone will identify the right package.
