If you change the appareance of your GNOME desktop, Debian provides two packages : gnome-themes and gnome-themes-extras
To install them :

root@localhost:~# apt-get install gnome-themes gnome-themes-extras

To choose one of the available themes :

fool@localhost:~$ /usr/bin/gnome-appearance-properties &

Here is what you should have :

To install other GNOME themes, please visit :
http://gnome-look.org/

On this website, you can find plenty of wallpapers, icons, GTK2.x Themes/Styles. If you want to have a new full GNOME theme, just choose GTK2.x Themes/Styles :

Checking the ink level of your printer

There are several existing tools to check the ink level of your printer.
Let’s take two of them : ink and inkblot

Install them :

root@localhost:~# apt-get install ink inkblot

ink is a command-line tool whereas inkblot is an ink level monitor with a GUI.
Please verify that your printer is currently supported :

http://libinklevel.sourceforge.net/#supported

If your printer belongs to the list of the supported ones, you have to add read access to the device
which stands for your printer :

root@localhost~# chmod o+r /dev/usb/lp0

As a non-root user, to check the ink level :

fool@localhost:~$ ink -p usb

Here is the kind of result you could expect :

ink v0.5.0 (c) 2009 Markus Heinz

hp deskjet 5550

Black:                         70%
Color:                         87%

If you launch inkblot from your Gnome menu, then a icon will appear in your tray icon.
By left-clicking on it, you will get the status of your ink level within a pop-up.

More info :   man ink
                  man inkblot

Nota Bene : make sure that your printer is correctly plugged and switched on.

Gtk-WARNING **: Unable to locate theme engine in module_path: « ubuntulooks »

Each time I launch a graphical application like gedit as a non-root user, I get this error :

To solve this problem, please install the following Debian package :

root@localhost:~# apt-get install gtk2-engines-ubuntulooks

Try to relaunch your graphical application :

foo@localhost:~$ gedit &

You will  not get the initial error message anymore.
