[lubuntu-devel] [Bug 1288786] Re: pkexec does not launch graphical authentication

[tombert]

The issue still is open in Ubuntu 18 LTS.

pkexec normally opens a graphical login, but when doing a "su -l
<differentuser>" it prints a selection in the terminal. No matter what
user is then selected, the authentication will fail.

Title:
  pkexec does not launch graphical authentication

Status in policykit-1 package in Ubuntu:
  Confirmed

Bug description:
  Installed Trusty Tahr Lubuntu Beta1 version and added xubuntu desktop.  In buth desktops, I tried to launch synaptic to install some packages.  If I try to launch from menu, nothing seems to happen.  From a terminal, I ran
    pkexec "/usr/sbin/synaptic"
   and saw that it asks for password in the terminal window, instead of popping up an authentication window like previous Ubuntu version did.  That was why I saw no authentication request when launching from menu..  I have a workaround)launching from Terminal window), but this should be fixed before release.
