I would get rid of greying out these buttons completely. You will never know whether the user is able to authenticate as admin, because you cannot know whether the user knows the password of an admin account if you do not ask for it. In all cases where the buttons are greyed out, but the user would know how to authenticate, this will create frustration.
Furthermore, there is no advantage of having the buttons greyed out. If you want to signal to the user that they require more rights, you can put a lock symbol on them (isn't there an example in the time settings dialogue for this?). This solution would be the easiest to implement and to use. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to language-selector in Ubuntu. https://bugs.launchpad.net/bugs/1008344 Title: checks "admin" group membership instead of querying polkit Status in “language-selector” package in Ubuntu: Triaged Bug description: In a new install of Ubuntu Precise, I cannot make any system-wide changes in the language selector (such as installing languages or clicking "Apply System-Wide"), only user-specific changes. All those controls for system-wide changes are greyed out, although my user does have sudo abilities and I would be able to enter the root password of the machine. The machine is freshly installed, but with customizations specific to our site, e.g. ldap authentication for users. Specifically, my user is an ldap user, not a local one, and there is a group in the ldap directory which was granted sudo capability by adding it to /etc/sudoers. My user is part of that group. sudo on the command line and gksudo work fine.
