    Hello and Welcome

    Try selecting the old kernel at boot . This won't solve the problem, but may allow you to try some things from the desktop if the old kernel loads. Post any messages if any you have seen as well.

    Is it hanging at the login screen after you type and enter the password?
    Like you type the password and then it leaves you a blank password field, but nothing else happens.

    Or does the screen just go black.

    If it's the former, then perhaps it's the issue of the package ubuntu-session not getting installed correctly.
    Older versions of Ubuntu had unity's session in the package gnome-session.
    But for 14.04, they made a new one called ubuntu-session.
    You might try this
    press ctrl+alt+F1(or F2-F6)
    enter your name and password.
    Then try installing the ubuntu-session package
    Code:
    sudo apt-get update && sudo apt-get install ubuntu-session
    then
    Code:
    sudo restart lightdm
    if it doesn't load, maybe a full reboot and see...
    It's all guess work though.

    If though it's the latter, and the screen is just blank then we'll have to get into some deeper stuff, maybe.

    This is what I see after login

    I can see two kernel versions on boot screen and selected the older one to boot with but that did not work.

    After that I tried
    Code:
    sudo apt-get update && sudo apt-get install ubuntu-session
    Code:
    sudo restart lightdm
    Above commands also could not solve the issue.

    It seems you're hanging at the login screen, like it's trying to load the desktop.
    Perhaps a reinstall of the desktop might help
    Code:
    sudo apt-get install --reinstall ubuntu-desktop
    or
    Code:
    sudo apt-get install --reinstall unity
    I also think it might be a compiz issue, maybe.
    Or something is preventing compiz from loading.

    I tried both the commands but its the same story.
    Should I wait for the Final Ubuntu 14.04 release?

    The way that it's hanging for you, to me, seems like compiz isn't loading correctly.
    Maybe a reset is in order.
    Look over this
    http://www.webupd8.org/2012/10/how-t...in-ubuntu.html

    See if that helps.

    I have the same problem.
    After upgrading to ubuntu 14.04 desktop did not load but it loaded using the old kernel. I formatted my hard drive and reinstalled ubuntu but the desktop still does not load.

    Has anyone found a solution to this problem? My second machine which I decided to upgrade has this exact same problem.
    I followed the instructions in this thread and in this one here but when I got to this part
    Code:
    dconf reset -f /org/compiz/
    I get an error message.
    Code:
    error: Cannot autolaunch D-Bus without X11 $DISPLAY
    I have no idea what to do from here.

    EDIT:The only kernel present only says Ubuntu or Advanced options for Ubuntu.
    I've since followed the instructions in a post in this thread but it was the same story when trying to log into gnome.

    I have had the exact same problem since yesterday as well. To fix it I had to install gnome-panel then run unity reset through unity tweak tools.
    Ctrl + Alt + F1,
    sudo apt-get install gnome-panel
    sudo mv ~/.Xauthority ~/.Xauthority.backup
    Reboot and select gnome on login.
    once logged in open a terminal Ctrl + T
    sudo apt-get install unity-tweak-tool
    unity-tweak-tool --reset-unity
    log out and log in again using unity this time and that fixed it for me.
    I installed unity-tweak-tool via the ctrl+alt+F1 screen and tried launching it but ended up with an infinite looping of
    Code:
    error: Cannot autolaunch D-Bus without X11 $DISPLAY
