Welcome to your desktop.

4.5 Nautilus

Nautilus opens a window for every single folder by default - to change this open any folder and edit the settings. It's also a good idea to enable the delete command that bypasses the trash - because if you delete something from external storages with the standard delete command, the things will not really be deleted but moved to a trash on the device (.trash). This trash will not be affected when you delete the trash on your desktop.

Now it's user-friendly.

In this step we'll make the fonts eye-friendly and change the resolution to a value that is used by most operating systems. The font settings are available in the gnome system menu.

Choose 9px as font-size for all fonts. Select "Subpixel smoothing" if you're using a LCD-monitor. Afterwards click on "Details".

Apakah itu centos.

CentOS merupakan distro yang dikembangkan berdasarkan distro Linux Red Hat Enterprise Linux (RHEL) 5.2 dan tersedia untuk arsitektur i386 dan x86-64.

Sebagai salah satu cloning Red Hat, distro CentOS setahun silam meluncurkan versi 5.0 kendati sejumlah pihak berani mengklaim bahwa CentOS merupakan distro yang 100 persen compatible dari RHEL yang memiliki stabilitas, layaknya sebuah sistem operasi enterprise namun tanpa harga sertifikasi dan dukungan support teknis.

Sementara itu, RHEL 5.2 sendiri baru diluncurkan oleh Red Hat sebulan silam yang langsung diikuti oleh update yang sama yang dilakukan oleh CentOS 5.2 terutama pada update core Xen virtualization hypervisor version 3.1.2, serta dukungan yang lebih baik untuk arsitektur NUMA (Non-Uniform Memory Access).

CentOS 5.2 juga memberikan supports virtualization yang lebih baik pada CPU 64 bits dan 512 GB memory. Sementara untuk device seperti WiFi supports, CentOS juga memberikan update termasuk versi terbaru dari sejumlah aplikasi seperti Gnome, KDE, dan OpenOffice.

Sayangnya, semua fasilitas update itu hanya bisa dinikamti untuk arsitektur i386 dan x86-64 sementara untuk PowerPC, IA64, dan Sparc belum diluncurkan.

Menurut pengembang CentOS, para pengguna tidak perlu kuatir untuk melakukan update baik dari versi CentOS 5.0 ataupun 5.1. Pengembang sudah menyediakan scripts yum upgrade, yang akan membuat sistem operasi langsung terupdate ke versi 5.2.
