Comment 24 for bug 1253693

recently it happened with 15.10 usb install with persistent storage that the panel lost logout, restart. i booted then without casper-rw, i.e. removing the persistent flag to compare where the buttons are available (see here for boot options: http://shallowsky.com/blog/linux/install/ubuntu-persistent-live-cd.html ) . then i used dconf dump / > dump.conf both times and compared the two files. the difference is:

+[apps/indicator-session]
+suppress-logout-menuitem=true
+suppress-restart-menuitem=true
+suppress-shutdown-menuitem=true
+suppress-logout-restart-shutdown=true

i am still wondering what triggers ubuntu to make these settings without me wanting it to do it.
