Ubuntu 12.04 Desktop Issues
People are getting prompted to install 12.0.4.1, doing it and then either it breaks or they are totally lost.
Resolution
If its completely broken:
backup and reinstall 10.04
otherwise: install Mate and Gnome Classic .
Installing Mate and Gnome Classic
Mate
sudo add-apt-repository "deb http://packages.mate-desktop.org/repo/ubuntu precise main"
sudo apt-get update
sudo apt-get install mate-archive-keyring
sudo apt-get update
sudo apt-get install mate-core mate-desktop-environment
[ http://mate-desktop.org/install/#ubuntu ]
Make sure you put a shutdown button (and a logout button), on the top panel.
On Mate make sure you put a shutdown (and optionally a log
out button), on the top panel, on gnome classic put a link to firefox (and evolution) there.
Tweaking Mate
Gnome Classic
sudo apt-get install gnome-fallback
Then put a link to firefox (and evolution) on the top panel. IIRC you need to press alt + right click to add things to the panel in Gnome Classic.
We should install both but select Mate as the default.
Selecting the Default Session
You switch between sessions on the log in screen by clicking on the Ubuntu logo/circle next to the username. This is non-obvious. Once you have selected a session once it will remember your choice.
Don't forget to do this for every user.
You will need to backup the password file (cp /etc/shadow /etc/shadow.bak) so you can change the password ehern doing this in Tech Support. Don't forget to copy the password file back over. (You don't need to do this if you have the password)
Antelope in Tech Support (on the left) has a 12.04 virtual machine with Mate and Gnome Classic on them. Mate has been set up with shutdown added.
