GDM2 - Change The Login Screen Appearance  

Although the login on the new Ubuntu systems is very... Interesting. Some people would like the ability to change it. I have found three ways, and here they are from easiest to hardest.

Get Nautilus Text Based Address Bar Back  

One of the first things I noticed when I started Ubuntu 10.04 was the missing option to toggle between the button-mode and the text-based address bar in Nautilus, with a simple mouse click. 

First of all there is a key-shortcut to toggle between both modes; Simply press CTRL + L.

To make the change more perminent, open the Configuration Editor and then navigate to “/apps/nautilus/preferences/” and either enable or disable the checkbox of the key that is called “always_use_location_entry". 

That sould do it....

Gimp - Batch convert xcf image file to png image file  
gimp -n -i -b - >>EOF
(let* ( (file's (cadr (file-glob "*.xcf" 1))) (filename "") (image 0) (layer 0) )
  (while (pair? file's)
    (set! image (car (gimp-file-load RUN-NONINTERACTIVE (car file's) (car file's))))
    (set! layer (car (gimp-image-merge-visible-layers image CLIP-TO-IMAGE)))
    (set! filename (string-append (substring (car file's) 0 (- (string-length (car file's)) 4)) ".png"))
    (gimp-file-save RUN-NONINTERACTIVE image layer filename filename)
    (gimp-image-delete image)
    (set! file's (cdr file's))
  (gimp-quit 0)
