Hello,

startx
OR

startxfce4

I tried to change runlevel from 2 to 5 but it dint help.

On Debian based distros, changing runlevels from 2 to 5 generally will not help. You need to setup a login manager e.g. gdm to start at boot time. To do this, install the login manager and then run

sudo update-rc.d gdm defaults
Hope that helps.

sudo update-rc.d gdm defaults
System startup links for /etc/init.d/gdm already exist.

Seems its already exist.

Can you run GDM manually e.g. by doing

sudo /etc/init.d/gdm start
Does it startup without any errors?

GDM is controlled in this case by the symlinks in /etc/rc2.d. To disable it, you would run something like this:

sudo mv /etc/rc2.d/S21gdm /etc/rc2.d/D21gdm
The "S" tells the system to run the target script, whereas "D" tells it to disable. The number indicates the level of priority given to the script. The only thing you need to change is the letter. Simply change it back to re-enable the display manager.
