Description of problem: There is no user switching applet in xfce, but it is possible to user switch from locked screensaver. Version-Release number of selected component (if applicable): xfdesktop-4.6.1-2.fc12.x86_64 gdm-user-switch-applet-2.27.90-2.fc12.x86_64 gdm-2.27.90-2.fc12.x86_64 gnome-screensaver-2.27.0-10.fc12.x86_64
The simplest solution is to add a launcher with "gdmflexiserver" as command. The better solution is the xfce4-xfswitch-plugin. It's waiting for review at https://bugzilla.redhat.com/show_bug.cgi?id=524413 *hint* *hint* Reassigning to myself.
Fixed in xfce4-panel-4_6_1-4_fc12. http://koji.fedoraproject.org/koji/taskinfo?taskID=1718435
