I have upgraded my Ubuntu 11.10 to 12.04. I could not see "other" login option in the login screen. it shows only "Guest login" and "User login. The User Login ask only password and I had never entered in as User login so that I do not know about password of User login. My question is how to login as root from the login screen? how can I get "Other login" option to login as root or some other user? before asking this question I have tried the following:
try to add the
greeter-show-manual-login=trueline at the bottom of
/etc/lightdm/lightdm.conffile as Guest login but i get access denied error.
i do not know the password of User login (ask only password while login) to purpose of adding above line.
from the safe mode login, i could login as root but i could not add the above line the lightdm.conf file . i got read only error so that i tried to change the permission to 777 like the following
chmod 777 lightdm.conf(while I am in the /etc/lightdm/ dir). but I got the error the file marked as/is read only in the file system.
In 11.10 version I have created 4 users. I can see that the users exist in 12.10 . so I am sure that the user accounts are not removed in upgrade process.
In short, I need Other login option on my login screen? how to get it?
I have add the following line the
/etc/lightdm/lighdm.conf file on recovery mode
and I saved the file using
/etc/lightdm/lighdm.conf file looking as the following:
[SeatDefaults] greeter-session=unity-greeter user-session=ubuntu greeter-show-manual-login=true
if I commit any mistake please correct me. For this problem I have wasted the two working day and all the works are in pending.
