I just installed Ubuntu 10.04.4-alternate as I would like to have the feature of encryption LVM. But after installation, the system boot into text mode, like Ubuntu server but not Ubuntu desktop. Is it so that alternate version doesn't provide GUI feature??
This is normal. You have to install the GUI with:
after logging in.
If you like you can have more desktops like kubuntu,Lubuntu,Xubuntu also.
all you need to do is just replace ubuntu with kubuntu in the above command and so to get those GUI's.
