When you customized your Ubuntu desktop to replace the brown theme, you may have overlooked the login window. GNOME’s login window, called GDM (GNOME Display Manager), can be easily customized by installing themes.
You can choose a GDM theme you like from GNOME-Look’s GDM category. I use the “Sky is the limit“ theme:
On the theme’s page, click the link to download it and save the file to your desktop.
System->Administration->Login Window. Select the
Local tab. Now drag
and drop the theme file from your desktop into the theme list.
Choose the theme you want to use by selecting the option button corresponding to
the theme. It’s even possible to use random themes by selecting
selected in the
Theme drop down box and selecting multiple themes.
You can delete the archive file you downloaded once the theme is installed.
Side note: I seem to have found a bug: Themes in .tar.bz2 format can be
installed by dragging them into the list, but only .tar.gz files are listed when
Add button. Anybody know what’s up with that?
