Only the foreground user should be able to trigger suspends

[Matthew Garrett]

The following patch checks that the foreground vt corresponds to the vt making
the suspend request. This prevents background users from triggering suspends
when idle.

Patch to do this

[Carthik Sharma (carthik)]

There is a patch, so is this to be applied sometime? Looks like it slipped through the cracks :)

I am also waiting for this bug to be addressed.

Marking as Fix Committed - we should look at it after Herd2 release.

That upload fixes the problem:

 gdm (2.17.7-0ubuntu1) feisty; urgency=low
 .
   * New upstream version:
     - New sockets command FLEXI_XNEST_USER and FLEXI_XSERVER_USER. This is
       used to start login procedure by programs like gnome-screensaver and the
       Fast User Switch applet.
     - Improvements to PAM logic so that it works more generically with PAM
       modules.
     - Better fix for not showing the face browser if the userlist is empty.
       This avoids a needless selection "changed" signal from getting generated.
     - Fix so ConsoleKit logic does not use dbus-glib bindings to using the
       lower level API instead. Fixes bug #400793.
     - Fixes for compiler warnings and for c99 compile issues.
     - Avoid catching sigchld when trying to call XOpenDisplay. This corrects
       an issue where GDM catches a second SIGCHLD when trying to restart.
       This causes the slave to freeze even though the Xserver and the session
       are killed, causing the display to no longer manage.
     - Improvements to PAM documentation in GDM docs.
     - Translation updates
   * debian/patches/11_powermanagement.patch:
     - updated with change by Matthew Garrett to limit suspend and hibernate
       to the foreground user (Ubuntu: #26618)
