a frustrating one, however.
I ran the override (code follows) and now 12.04 (desktop i386) won't boot to the welcome screen at all. it just displays ........ endlessly. I'm able to login as root from the recovery console..so I can access the system. I can see my samba share from my laptop (which I'm obviously using to type this)
I SHOULD have checked out the code before I blindly paisted it into the command line.
So, I'm sure there is a way to undo this.
I'm keen to learn how to config Lightdm.
Please help, so I can boot to a gui.
Also, startx does not work.
echo "manual" | sudo tee -a /etc/init/lightdm.override
