           Summary: Missing shutdown option from X session on workstations
           Product: Skolelinux
           Version: lenny
          Platform: All
               URL: http://wiki.skolelinux.de/YoungsterMeeting2010/Reporting
                    #head-f8a7ce0bd9784ed1a6932288cddfa69627eb8ac9
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P3

        ReportedBy: rgx@gmx.de


Users need the option to shutdown their workstation (!) from within a running X
session (e.g. from their KDE desktop).

With lenny, the corresponding button has vanished. This was discussed on
several occasions on the mailing list [1], but never made it to BTS.

It was Jonas who pointed out that the reason for this bug was probably neither
KDE settings nor Kiosk mode, but rather user rights according to policykit/hal
[2].

Accordingly, I found some hints, cf. [3]:

What does /etc/PolicyKit/PolicyKit.conf look like?

 polkit-action 
 polkit-auth --user USER --grant org.freedesktop.hal.power-management.shutdown

or add these lines to PolicyKit.conf:
##########
<match action="org.freedesktop.hal.power-management.shutdown">
        <return result="yes"/>
</match>
<match action="org.freedesktop.hal.power-management.reboot">
        <return result="yes"/>
</match>
##########
