Ubuntu 11.10

It seems like Ubuntu dropped Gnome shell and replaced it with Unity. Oneiric Ocelot will be shipped with Unity as default. But they say it will be much more improved.
Also heard a rumor that Fedora 16 will be shipped with unity.
Oneiric Ocelot will be powered using Linux Kernel 3.0 final
Other changes are improved application switcher, smoother compiz grid plugin and software center also got some improvements.

Gnome3 Customization | Change Icon Size

To change the size of the icons in the activity Tab, you need to customize the file /usr/share/gnome-shell/theme/gnome-shell.css.

open the file in gedit or any text editor you like

sudo gedit /usr/share/gnome-shell/theme/gnome-shell.css

the following section describes the icon size and table structure.

.icon-grid {
    spacing: 36px;
    -shell-grid-item-size: 118px;
}

.icon-grid .overview-icon {
    icon-size: 96px;
}

so to reduce the size of the table , you need to change the entries spacing and -shell-grid-item-size

to reduce the size change the values as follows


.icon-grid {
    spacing: 25px;
    -shell-grid-item-size: 50px;
}

.icon-grid .overview-icon {
    icon-size: 50px;
}
