Ubuntu Tips And Tricks

Gnome Shell - Tron Legacy

This is a GNOME Shell theme inspired by the film Tron Legacy. Icons in the screenshot are also provided.

Font used is called Zero Threes

Light Cycle wallpaper

Instructions:

Backup your /usr/share/gnome-shell/theme directory (or where ever you have GNOME shell installed).

Extract the zip file and copy the theme directory to /usr/share/gnome-shell/

Restart GNOME Shell by Alt, F2, then type r and press enter.

Icons

Icons are in the directories that correspond to your icon theme. Backup your current icon theme and replace the icons in their directories. Apps use 48x48, places use 16x16, the application switcher uses scalable and the status menu uses 16x16. Your icon themes are in either /usr/share/icons or locally ~/.icons.

Switching Fonts

To use different fonts in GNOME Shell, just open the gnome-shell.css file found in your theme directory and find lines font: 10px sans; Replace "sans" with your font name, save the file and restart GNOME Shell. You must be superuser to do this.

NOTE

I recommend a version of GNOME Shell 2.31.2 to 2.31.5(out of date but 2.31.5 is installable with most recent distros like Ubuntu 10.10 and Fedora 14). Please don't use with Git(Jhbuild), since GNOME Shell has had a re-layout.

Performance

Due to the heavy use of shadows to achieve the glow, the performance may not be smooth on some systems. This is beyond my control, however remember that GNOME Shell is still in heavy development and does not reflect the final release quality.

See the GNOME Shell group for more info.

Git re-layout version is here, WIP [link]

The following theme mock-up by ~RustedThorn may be a tad indulgent on the branding scales, and closing an application via a menu every time would get real annoying real fast, but you know what? I really don’t care. It looks beautiful.
