[Bug 1008344] Re: checks "admin" group membership instead of querying polkit

[Gunnar Hjalmarsson]

Trying to summarize the suggestions so far:

* Ask polkit
I failed to make polkit provide the info we would need. If somebody knows how to do that, it would probably be the best and easiest solution. The code in the linked branch may or may not be useful as a starting point.

* Drop the is_admin check
As is argued for in comment #16, #23 and #24, we could drop the is_admin check. But there is at least one thing that would need to be addressed first in that case:
Besides determining whether some buttons should be greyed out, the is_admin check also controls if language-selector shall look for missing langpacks. If a missing langpack is found, the user is asked if s/he wants to install it. Neither the missing langpack test nor the question would make sense if you don't have permission to install langpacks.
Possibly it's time to reconsider this check each time gnome-language-selector is launched? Considering the planned switch from the language-selector UI to the region capplet in gnome-control-center, this needs to be looked into soon anyway.

* gsettings
As a workaround, if none of the above two options is doable right now, I mentioned in comment #18 the possibility to use gsettings to force the buttons to not be greyed out.

So, how do we proceed?

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.
