login-screen

My netbook runs a dual OS(Windows7 & Ubuntu 12.04). After Ubuntu login screen appears, that’s it, it gets hanged, can't even move my cursor nor type my user name.

I had to turn off my system and boot again. Still its not sure that it won't freeze out at login screen again, but this is the temporary solution I have to get into Ubuntu.

This freezing at login screen doesn't happen every time, it happens randomly. It seems like I had to enter into Ubuntu purely based on my luck, which is quite irritating. I found many other types of login problem in Ubuntu when I googled, which were quite different from my case. So any1 kindly help me out.
