getting Gtk-WARNING while using gksu

Question

while using gksu i get Gtk warning, for example:

$ gksu gedit /etc/fstab

(gksu:2792): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",

(gksu:2792): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",

(gksu:2792): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",

(gksu:2792): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",

and when i close running app (in above example gedit), i get:

(gedit:2796): Gtk-WARNING **: Attempting to set the permissions of `/root/.local/share/recently-used.xbel', but failed: No such file or directory

(gedit:2796): Gtk-WARNING **: Attempting to store changes into `/root/.local/share/recently-used.xbel', but failed: Failed to create file '/root/.local/share/recently-used.xbel.8R7MBW': No such file or directory

(gedit:2796): Gtk-WARNING **: Attempting to set the permissions of `/root/.local/share/recently-used.xbel', but failed: No such file or directory

i'm using ubuntu 11.10 64bit. any ideas how to solve this issue?

Answer 1

Those are more or less harmless.

• First one is about a missing GTK engine.

For your specific error:

    sudo apt-get install gtk2-engines-pixbuf

To find the package in error:

sudo apt-get install apt-file

Search for your module name that is given in your error i.e. prefix with lib and suffix with .so - so in your example pixmap you need to search for libpixmap.so

apt-file find libpixmap.so

This will give the package to install e.g.

gtk2-engines-pixbuf: /usr/lib/i386-linux-gnu/gtk-2.0/2.10.0/engines/libpixmap.so
libgtk2.0-0-dbg: /usr/lib/debug/usr/lib/i386-linux-gnu/gtk-2.0/2.10.0/engines/libpixmap.so

• Second one happens, because the root user (/root directory) doesn't have a .local directory. Create it by running:

  sudo mkdir -p /root/.local/share
