I tired startx also... but no use....
I have nvidie 8400GS M in my laptop. Can u please help me out from this??

Thanks A lot.

did you select for a GUI to be installed during setup?

on the command line try the following:

yum list |grep gnome

and it should come up with something like the following

Did you perhaps immediately after the logon was presented but before the password was entered, choose other than gnome. Say Classic Gnome, or Compiz Gnome? That is a good starting point
Select plain Gnome and take it from there. Move mouse to top left corner. Tell us what happens.

when there is login screen ..bar is shown on the top..bt as soon as i logged on it goes n there is nothing after waiting and doing everything....:frowning:
