Hello forum,
Seems that only I have alot of questions regarding Ubuntu 
In Ubuntu 12.04 LTS the gnome I have been using gdm and lightdm.
In lightdm the top and side bars are aka "unity" and can be removed using
apt-get remove unity
I need to do the same for menu bars gdm. I do not know what the package is called, if you happen to know how to remove or what it is call i'll greatly appreciate.
PS. I tried removing gdm and installing lightdm, it would not auto into GUI and i have to invoke it by logging in and then
service lightdm start
, then log in again. I have checked the /etc/X11/default-window-manager and it's set to /usr/sbin/lightdm. Anyway one thing at a time and i'll like to figure out this problem for gdm first.
Thanks
