People using VPNs are not the majority, and we can disable automated detection of timezone if we're connected over a VPN. Plus, we can also use GPS devices when present.

If people are smart enough to change their timezone manually, they are smart enough to understand their laptop still uses the previous timezone because it has no way of finding out you've moved. > The trouble this will cause is a classic computer problem: it will be a > system that is > smart enough to be right most of the time.

So you'd suggest computers should always wait for users to do things manually, just to avoid being smarter than them? The automated solution is better than nothing. Anyway, discussing this here is pointless since it will be implemented in GNOME and I'm not involved at all in this work. > Besides, there is a laptop-detect package in Ubuntu: > > > $ aptitude show laptop-detect > > Package: laptop-detect > > State: installed > > Automatically installed: no > > Version: 0.13.7ubuntu2 > > Priority: optional > > Section: utils > > Maintainer: Ubuntu Core Developers <[email protected]> > > Uncompressed Size: 57.3k > > Depends: dmidecode (> 2.8-2) > > Description: attempt to detect a laptop > > laptop-detect attempts to determine whether it is being run on a > > laptop or a > > desktop and appraises its caller of this. > > > So, it is certainly technically possible to tell if you're on a > laptop.

And the fact that your computer is a laptop doesn't mean you want to grant this kind of permissions to all users on the system. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/696115 Title: Timezone should not require superuser on laptop -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
