Well i was working on maya when suddenly my keyboard and mouse stopped responding so i had to press the system reset button. After that i recovered my system using
I even tried
rm -rf .gnome/.gconfd from my home directory in a virtual teminal (by pressing CTRL + ALT+F1)
But I still was not able to login with Gnome classic or just gnome selected, however if i change desktop environment to Gnome with no effects or unity everything works fine...
What might be wrong , since I am new to Ubuntu and still learning I need some help to get back to Gnome classic. Even Gnome with no effects is fine but I do not like the close, minimize and restore button on the left ..
