Hope it's ok to ask questions about Linux mint 13 which is based on ubuntu 12.04. All of a sudden my system boots to tty1 prompt. even in tty prompt I am not able to login. But root can login.

Any clues?

The problem which makes you boot to tty1, cannot be diagnosed without more information.

Try to gather information about what happens "behind de scenes" during the boot, by looking into the log files stored in /var/log:

  • login (in tty1) as root

  • startx
    (this is how to manually start the X window-system - it should give back some error and clues about it)

  • cat /var/log/boot.log
    (pay special attention to anything "failed" or "error"

  • less $(ls -rt1 /var/log/Xorg.* | tail -1)

  • less /var/log/kern.log
    (use arrow keys to move inside document, and to quit write :q)

  • less /var/log/syslog

Post the contents of the errors/fails that you find, as these will help grasp the cause of the problem

Thanks @zipzap. I have started looking at those. There was no error messages after startx. In bootlog found the following:mdm[1341]: WARNING: mdm_config_parse: Authdir /var/lib/mdm does not exist. Aborting. mdm_config_parse: Authdir /var/lib/mdm does not exist. Aborting. –  sriram pandey Nov 20 '12 at 13:47
google for that error, and see if someone experienced the same problem (most probably as always happens) - good luck –  zipizap Jan 2 '13 at 23:59
