particular module but i can't able identify which one it is,
after restarting my system i can't enter into root login but before i have
done it,then i need to enter into userlogin it can't able to start gdm

            i pressing alt+f2 then i logged in terminal mode .then i gave
start gdm it doesn't work,i entered startx command it also doesn't work,  it
shows the error
