Description of problem: Many of the menu entries under Settings fail to actually do anything. If one runs xfce-setting-show from the command line, it just returns instantly without doing anything. Version-Release number of selected component (if applicable): xfce-mcs-manager-4.4.2-2.fc9.x86_64 (Rawhide) How reproducible: 100% on this system -- haven't tried other machines.
xfce-setting-show should just return, it sends a message via xfce-mcs to the xfce-mcs-manager to show the settings window with all the various sections. I can't duplicate this here... it works just fine for me. Are you sure this window isn't just appearing somewhere you aren't looking? Do you have xfce-mcs-manager running? Is there anything in ~/.xsession-errors ?
xfce-mcs-manager is running. Nothing in ~/.xsession-errors. This is a new F9 beta install, although I did preserve /home. But it also happens on a new test user, so it's not just cruft in my dotfiles. What's the mechanism of communication between xfce-setting-show and xfce-mcs-manager? Perhaps something is broken there.
Strange. selinux enabled? Anything in your /var/log/audit/audit.log? How are you logging in? Is ConsoleKit running and 'ck-list-sessions' showing your session? How did you install Xfce? 'yum groupinstall XFCE' ? If you run that now does it pull in any new packages that were not installed before?
Okay, so, after running yum upgrade this morning -- which upgraded *no* xfce packages -- and rebooting, it works. *shrug* Thanks for looking.
