Behaviour on my machine is erratic: right now the screen won't turn off, no matter what value I choose. But on some boots the value I choose does work, even though it reverts to "never" on reopening.
When I go to the Brightness & Lock panel, even before I change anything, I get the following error message in the terminal: (gnome-control-center:4680): GLib-CRITICAL **: g_variant_get_int32: assertion 'g_variant_is_of_type (value, G_VARIANT_TYPE_INT32)' failed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1228939 Title: The "turn screen off when intactive for" option is not saved To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1228939/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
