The IceWM Control Panel (IceWMCP) IcePref2 Theme Designer tool allows you to easily create and modify themes for IceWM.
IceWM Control Panel (IceWMCP) is the first full-featured, Gtk-based control panel for IceWM. It is meant to run in IceWM, but can be used in ANY window manager as a general-purpose control panel.
IceWMCP is multi-lingual. Currently, the following languages are supported: English, Spanish, Russian, Traditional Chinese, French (partial), and Finnish (IceWMCP-IceMe only).
Developers: If you would like to use IceWMCP as the foundation for a new control panel (for a new window manager, etc.), see the developers release of IceWMCP. IceWMCP was inspired by the Qt-based application called IceCC, but includes many more tools, a more familiar Windoze Control Panel-like interface, and uses the MUCH faster Gtk user interface (Who runs a fast Window Manager like IceWM, to launch SLOW-running, memory-intensive Qt/KDE-based applications?? I sure dont).
Lets face it: IceWM and fast Gtk interfaces work well together. In addition, because IceWM Control Panel is written with a TRUE open source widget set, Gtk+, you dont have to worry about the licensing problems associated with proprietary QT-based applications. IceWM Control Panel is TRUE open source, through and through.
Version restrictions:
- Access to a Bash shell (very important)
- Python (2.2 or better), PyGtk-2 (1.9.9/2.0.0 or better)
- Gtk+ 2.0.6 or better - neither Gnome nor PyGnome is required
- (IceWMCP versions 2.5 and earlier require Gtk+1 and PyGtk-1 0.6.9)
- Your version of PyGtk should have the Gdk-Pixbuf modules on your system
- Please run ALL IceWMCP programs from a BASH shell: Using other shells such as ksh, pdksh, csh, tcsh, etc. is likely to cause problems.
- If your IceWMCP programs have trouble launching other applications, it is most likely because you are using something other than a Bash (/bin/bash) shell.
- Run the programs from Bash...period!

gentoo splash theme chooser is a gentoo application to choose a gensplash theme.

You can choose a theme and it it will make a symlink from this theme to default in /etc/splash.

After that it mounts /boot and does the following command:

splash_geninitramfs -v -g /boot/fbsplash -r resolution default

It does not touch grub.conf

There is a Readme included with an example grub.conf and further information. For me it is a handy tool and I hope it will help other gentoo user too.

gtk-theme-prefs is a GTK+ theme manager, written using Gtk2-Perl. There are already a number of pure GTK+ theme managers.

This one differs from the others in that it fairly closely follows the GNOME HIG, and uses Glade.

boo karamba theme has been adapted from the karamba eyes theme, by replaceing the eyes with terasa(boo).

Kubuntu Human Theme was created because I started to like the Ubuntu Human theme and when I switched to KDE, I was missing it there. The theme is assembled from various Ubuntu style items, most of which can be found on KDE-look: Ubuntu Cristal background, Human (Revised) color scheme, nuoveXT icons, Ubuntu Kmenu icon, SoftGlow Orange kicker, default Plastik style and Crystal window deco.

Installation of .kth file thru KDE Control Center--Theme Manager--Install; then, if you want exactly the same look, get and install the above items (search on KDE-look). The Kmenu can be changed by replacing each kmenu.png in /usr/share/icons/nuovext/[SIZE]/apps/ Then refresh your icon set.
