Cara Install GNOME 3 di Ubuntu 10.04

salam jumpa kembali..udah lama banget ne ga nulis-nulis artikel tentang linux, pada kesempatan ini saya akan menulis artikel bagaimana caranya menginstall GNOME 3 di ubuntu 10.04, setelah melihat ubuntu versi 11.04 rasanya saya kepengen juga untuk menginstall GNOME 3, daripada harus install fresh ubuntu, mendingan kita install desktopnya aja..:D oke langsung saja

Berikut langkah - langkahnya :
1. Seperti biasa buka terminal dan ketik baris berikut
    sudo apt-get install gnome-shell

2. Sebelumnya pastikan dulu anda tidak mengaktifkan visual effect pada sistem

    anda, caranya klik kanan pada desktop dan pilih change desktop background 

    kemudian pilih none, ini untuk menghindari crash pada saat menginstall

    gnome-shell

3. Setelah selesai menginstall, langkah selanjutnya adalah buka

    System->Preferences->startup application 
4. Kemudian klik add, untuk nama tulis gnome-shell dan untuk command tulis
    gnome-shell --replace, kemudian klik add
5. Jangan lupa tanda centang harus tercentang jika ingin mengaktifkan
    perubahan dari gnome-shell
6. logout dari sistem anda dan login ulang dengan username yang sama
    dan GNOME 3 akan otomatis di aktifkan.
