The Oracle Solaris 11 text installer does not include the primary software package that includes the GNOME 2.30 desktop. If you use this installation method, you will need to install the solaris-desktop package afterwards. For information about using the pkg install command to add packages after a text installation, see Adding Software After a Text Installation in Installing Oracle Solaris 11.2 Systems .
If you have a situation where you need to install the solaris-desktop package on a system running a live session, create a new boot environment, install the solaris-desktop package, then activate the new boot environment as follows:
# beadm create be-name # beadm mount be-name /mnt # pkg -R /mnt install group/system/solaris-desktop # bootadm update-archive -R /mnt # beadm umount be-name # beadm activate be-name
