bad start-up after attaching external monitor

[kranti]

hi,
I am very new to the linux world.
I have a Lenovo 3000 N100 laptop which LCD does not work anymore.So I borrowed a monitor from my friend and started using it(it has been few days).I had installed Fedora-12 few months ago. After connecting the external monitor, I found that this one shows good graphical start-up but just upto the login screen(just before the login screen, login-screen does not come) and it proceeds no more.Though I can get the virtual consoles restarting xserver is of no use.

Please help me to find out any issue.

If you can get to a virtual console, you can look into the log files, for example /var/log/Xorg.0.log, and see what error messages Xorg provides.
