Ubuntu
xfce4-utils package

wrong value of XDG_DATA_DIRS

Asked by Italo Canepa

Hi
In a ubuntu 7.10 32bit or amd64 bit architecture I find this problem:
If I with synaptic install on my system Xubuntu and I digit:
icanepa@JtLaptop1:~$ echo $XDG_DATA_DIRS
I find:
etc/xdg/xubuntu:/usr/local/share/:/usr/share/:/usr/share/gdm/:/usr/share
icanepa@JtLaptop1:~$
instead of /etc/xdg/xubuntu:/usr/local/share/:/usr/share/:/usr/share/gdm/:/usr/share
(missing first slash)

This, for example, make impossible to install some program that use it, like NetBeans 6.1.
NetBeans fixed the problem in a new buid with a patch that put a slash if there insn't.

I try even in ubuntu 8.04 with a post installation of Xubuntu and I find the some problem with XDG_DATA_DIRS.

I'dont' know if I do something wrong or if it is a little problem of Xubuntu or XFCE.

Thanks
Italo Canepa

If I start a normal Gnome session the problem is not present.

On my gutsy box, the file: /etc/X11/Xsession.d/20desktop-profiles_activateDesktopProfiles has something to do with setting XDG_DATA_DIRS. Its a complicated script though, so I can't help much myself.

It might be a relevant piece of information though, when looking for somewhere to file a bug.. that file belongs to the package "desktop-profiles"

Scratch that, its unlikely desktop-profiles is your problem.

For gnome, GDM sets the variable. What display manager do you use?

Ok, if its XFCE4 in question, I think the bug is coming from xfce4-utils. That variable code is set by an Ubuntu patch:

Does the file:

/usr/bin/startxfce4 contain this statement? XDG_DATA_DIRS=.... ?

Take a backup copy, then try modifying it to include the "/" Does it work?

 Hi
I modified the script, and now works right:

if test "x$XDG_DATA_DIRS" = "x"
then
  XDG_DATA_DIRS="/etc/xdg/xubuntu:usr/local/share:/usr/share"
else
  XDG_DATA_DIRS="/etc/xdg/xubuntu:$XDG_DATA_DIRS:/usr/share"
fi
export XDG_DATA_DIRS

thank you very much!

I have now the correct path:
icanepa@JtLaptop1:~$ echo $XDG_DATA_DIRS
/etc/xdg/xubuntu:/usr/local/share/:/usr/share/:/usr/share/gdm/:/usr/share
icanepa@JtLaptop1:~$
