Im currently using 14.04, recently installed Gnome desktop but now window manager is crashing every time. Cannot do anything with the keyboard after open a folder! ex: cannot copy a folder using keyboard cannot press crtl alt or shift key. Can anybody help me to correct this issue?

I am not so sure what your running. At the login screen press Ctrl + Alt + F1 and login. Then post the output of these commands:

echo $DESKTOP_SESSION
and

find /usr/share/xsessions -name "*.desktop" -exec basename "{}" .desktop ";"
Also what are your computer specs (cpu, ram, graphics)?

This could be a graphics issue. From what I been reading the gt540m can be hard to set up.

You say that you added gnome to your install so I am guessing that this is a custom build.

If you want the gnome environment, it may be better to go with UbuntuGnome.
