login-screen

When I enter my password in the login box nothing happens. It is stucked there. It was running fine earlier. Actually, I installed the package gnome-panel and cairo-dock. Then I logged out and selected gnome classic session. Then I added a ppa from the webupd8.org to install the themes(link). I opened Ubuntu Tweak tool. When I changed the theme to Evolve the whole laptop stopped responding. None of my keyboard and mouse was working. So I was forced to do a forced shutdown. Now after restart I cannot login into ubuntu. I hear a loud sound of my laptop fan when the laptop is stucked. (Probably CPU will be at 100% when it stucked). Please help me. How can I login back to ubuntu? I am using ubuntu 12.04 and have installed all the latest updates..

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version. In this case, kernel 3.3 has seen some very good power management enhancements that are… >>> More
