lightdm (1.0.1-0ubuntu3) oneiric; urgency=low

  * debian/patches/05_gdmflexiserver_not_in_PATH.patch:
    - Make sure to insert our own utility path into PATH after PAM
      sets PATH, not before.  This ensures gdmflexiserver is present
      in PATH and can be found by gnome-screensaver, gnome-shell, etc.

Title:
  Can't switch user from a locked screen (no gdmflexiserver binary in
  $PATH)

Status in “lightdm” package in Ubuntu:
  Fix Released
Status in “lightdm” source package in Oneiric:
  Fix Released

Bug description:
  It is not possible to switch user from the gnome-screensaver lock
  dialog when using lightdm. Although lightdm provides its own
  gdmflexiserver implementation, it's not in the default $PATH, so
  gnome-screensaver doesn't find it and hides the option to switch user.

  Apparently, this was meant to be worked around by adding
  /usr/lib/lightdm to the default $PATH:

  <seb128> mterry, do you have time for a lightdm bug today? ;-)
  <mterry> seb128, sure
  <seb128> mterry, the gdmflexiserver path hack still doesn't work...
   mterry, that breaks user switching on the lock screen
  <mterry> seb128, guh
   seb128, bug number?
  <seb128> I knew you were going to love that :p
   mterry, it was IRC reported but I can file a bug if you want
   let me check if there is one

  <mterry> seb128, so to reproduce, I lock my screen and try to switch users?
  <seb128> mterry, well basically you uninstall gdm or move its gdmflexiserver away, (restart gnome-screensaver?), then try to lock your screen
   mterry, you should get no "switch user" button
  <-- mhr3 has quit (Quit: Ex-Chat)
  <seb128> mterry, the code is basically looking if gdmflexiserver is in the path, but it's not

  <mterry> seb128, this is without lightdm?
  <seb128> mterry, no, that's with lightdm
  * mterry wonders why gdmflexiserver isn't in the path

  --> thisfred (~thisfred@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx) has joined #ubuntu-desktop
  <seb128> mterry, because lightdm install it in /usr/lib/lightdm and your path hack seems to not work (my guess)
   mterry, remember you added code to add /usr/lib/lightdm to the PATH
   which is somewhat hackish ;-)
  <mterry> seb128, I remember.  But it was working...
  <seb128> well doing a "strings /proc/$(pidof gnome-session)/environ | grep PATH" shows it's not in the path
   mterry, yeah, I blame it on robert_ancell he probably broke it :p
