Can't log in to Ubuntu 12.04

After typing in password , this message displays on screen :
Stopping System V runlevel compatibilty

Hi ,

Follow this fix

1. When you are in login screen press Ctrl+alt+F2 to revert in Console Mode and login there.

2. Give this command first:

sudo service lightdm stop

3. then give this command:

sudo chown username:username ~/.Xauthority

Where username replace it with your actual username.

4. Then give this command to revert back to Login Screen

sudo service lightdm start

and try to login .

Thanks

I tried the steps, still didn't work :(

Can you login from Guest account ?

If yes , then login and open a terminal

give the results of

ls -la /home/username (username = your actual username from corrupted account)

Thanks

I doesn't work for guest account either. I couldn't log in till now.

This is bad.

Do you remember if you encrypted your /home directory ?

Usually problems with login caused by wrong permissions on .Xauthority
file (is a hidden file so the dot at front of the word)

But as you said you tried that and not succeed.

Maybe a graphics card driver issue ? But no , if it was such problem ,
then probably you would not have even a Login Screen.

Weird problem . I expected that you could login from Guest account.

You can try to create a new user and see what happens.

Follow these steps from Console Mode.

1. sudo service lightdm stop

2. sudo useradd "username" <= this command will create a new user.

3. sudo usermod "username" -g sudo <= this command will make the user
administrator.

4. sudo service lightdm start

and try to login from the new user.

Where "username" replace it with the username you prefer.

Thanks

I just did fresh install few days ago (10.10 ---> 12.04) and never encrypt the folder since then.

Everything goes just well, and it started goes wrong after I added one more workspace,

and then I switch to that new workspace.

Then, the desktop panel is gone, and I can't switch back to the first workspace, so I try reboot and log in, but fail.

Yeah, I added new account, still fail to log in :(

Ok ,

lets try this command

from Console mode.. it will be get some time , 5-10 minutes , so be
patient.

1. sudo service lightdm stop <= I am not sure for this command , if the
2nd command not work then skip this command and execute the 2nd direct.

2. unity --reset

When about 10 minutes passed you can stop the command with Ctrl+C .

Then reboot.

Thanks

This is what I got:

(log in as root)

1. service lightdm stop

It display this : lightdm stop/waiting

2. unity --reset

 It display this :

WARNING: no DISPLAY variable set, setting it to :0
(process:2048):GConf-WARNING **:Client failed to connect to the D-BUS daemon:
//bin/dbus-launch terminated abnormally with the following error:Autolaunch error: X11 initialization failed.

WARNING: environment is incorrect: No D-BUS daemon running

Did you just try to reset in a tty?
unity-panel-service : no process found
compiz(core) - Fatal: Couldn't open display :0

Can you give the output of:

lsb_release -a; echo $PATH

Thanks

Output:
No LSB modules are available.
Distributor ID : Ubuntu
Description : Ubuntu 12.04 LTS
Release : 12.04
Codename : precise
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

here is my $PATH
/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

Which is a LOT longer than yours.

Try
export PATH="/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"
sudo service lightdm stop
sudo service lightdm start

HTH

Still failed to log in :(
Anyway thanks for the fast reply, really appreciate the help :)
If I just format it, would it be okay perhaps?

Yes , but your data ?
If you don't have any important data , then just re-install. After all ,
re-installing Ubuntu is about.. what?
15 minutes top.

Thanks
