Xfce4 menu anomaly
 

If this has been answered before, I do apologize, but I can't even figure out how to search for it.

I am running Gentoo with the Xfce4 desktop. I have installed Mumble and it works fine... as long as I start it from the command line or from a launcher that I make. It is added to the menu under "Internet" by default, but as soon as I mouse over "Internet," the menu disappears and the right click menu is no longer available. Sometimes the entire panel disappears, but usually returns in a moment.

I have moved Mumble to the "Other" category in the menu, but it then disappears when I mouse over "Other."

I have also noticed that if I try to select an icon for the launcher, the dialog disappears as soon as I select an icon. I tried using the "Run Program" feature, but it won't even let me finish typing mumble and disappears as well.

What the heck could be causing this?

Also, just noticed that if I select "Log Out" from the menu, Gentoo seems to freeze. Eventually the chooser comes up to allow me to log out, restart, or shut down, but it takes a long time. Start up seems quite slow too. Any help is much appreciated.

Try creating another user on the system and login as that user and tell us if the logout process is just as slow as your current situation.

Thanks.

Solved it. First of all though, thank you Habitual for your suggestion.

To spare you the gory details, suffice it to say there was a line in fstab that I don't remember entering, but must have, that mounted cdrom0 at boot. This conflicted with udisk and caused the log out problem. The menu icon problem appears to have been caused by a pooched pixman install, so that's fixed now too. Only remaining problem? I cannot boot Mumble from the menu, even though the .desktop file Exec= line is correct. I created a desktop launcher that works just fine. I tried booting into the root desktop just long enough to confirm that it is not a permissions issue and it's not. Any ideas on this one?

What's in Mumble.desktop (or whatever)?

Any chance that a Mumble.desktop in ~/.local/share/applications is superseding one in /usr/share/applications?

Sorry to take so long to respond. Been busy sorting things out. Nothing superseding, but I fixed it with a simple re-install of Mumble. Then my slow logout problem returned, and I spent two days tracking that down as it wasn't what I thought it was, i.e. the fstab conflict. Turns out /usr/libexec/dbus-daemon-launch-helper permissions somehow got changed so that world could not execute it and therefore the Upower Daemon would not start. IOW it was a power management problem. If anyone runs into this problem and you are using Consolekit simply execute, as superuser, this command: chmod o+x /usr/libexec/dbus-daemon-launch-helper, and all should be fine again. This usually happens after an update.

Thanks for the help guys.
