I just upgrader to 12.04 from 11.10. The install appeared to go well but the computer goes through the usual boot with splash but the goes to the command line without a GUI. How do I open the GUI and fix this issue?

Hey there! Welcome to askubuntu! Can you please give a little more information in order for us to help you more. What kind of hardware do you have? Is this a laptop or desktop? Do you know what kind of Graphics Card is being used within the system? – itnet7 May 21 '12 at 1:55
yup along with above comment try this also . login there and type ** sudo start lightdm ** :) – Raja May 21 '12 at 2:17
@raja.genupula I agree that this could hypothetically work; you shoudl try typing sudo start lightdm – hexafraction May 21 '12 at 23:07
does your computer has an ATI video card? and if so, do you have installed the propietary drivers? if so, try using: sudo amdconfig --uninstall if not, press shift when booting to call GRUB and go to recovery mode. – victorhqc Sep 23 '12 at 17:23

There appears to be issues with the nouveau drivers. I suggest reinstalling 11.10 as I couldn't get 12.04 to work on my system either.
