A new twist. After my last apt-get dist-upgrade update, I cannot shut down my laptop with the log out dialog box. When I try, I get an error message:
GDBus.Error:Org.freedesktop.DBus.Error.Spawn.Child Exited:Launch Helper exited with unknown return code (1)
I get this same error message when attempting shut down or log out, but not with suspend. But suspend doesn't work, it just
logs me out and brings up gdm with a request for user name and password.
Is this a Debian error, an LXDE error, or something I did? Thanks in advance.
