I have installed Kubuntu 12.04 LTS. By mistake, I removed default login screen (Ariya). It is now showing this message:

Cannot login /user/shared/kde4/apps/kdm/themes/ariya

Now I am not able to login to previous GUI. It is getting login in command line.

How to resolve problem?

$ mkdir kdm && cd kdm
$ sudo apt-get source kdm

And in the unpacked package folder you will find KDM with the Ariya files included.

Here goes nothing (aka. the apt-file utility):

You can find contents in packages with "apt-file". It's an application, you have to install it. Then run the apt-file update command as a single user. And then, you can search.
With: apt-file find ariya

Another way if this one fails (the almighty --reinstall flag):
Just use the --reinstall flag with apt-get.
sudo apt-get install --reinstall kdm

(Do all this from terminal. Switch with "CTRL+ALT+F2" for example. Log in as you would do from the GUI. If you are in trouble with file management, use "mc" (sudo apt-get install mc) to copy the files. It's a gui file manager for the terminal. It uses ncurses.) – Shiki Sep 24 '12 at 10:27
in KDM both ".tar.gz" and "tar.xz" files I have to extract? – Digvijay Sep 24 '12 at 12:04
I am not able to find Ariya... – Digvijay Sep 24 '12 at 13:35
The dget command does the unpack for you. – Shiki Sep 24 '12 at 15:16
@green7: CTRL+ALT+T gives you the normal gui terminal. He can't login. So he can't bring up that either. – Shiki Sep 24 '12 at 15:18


I had removed the theme and ariya Atela not carrying the login graphic then appeared a msg like this: Not found the theme /user/shared/kde4/apps/kdm/themes/ariya ok and I gave then carried in order to make the text login with the command entered here and it worked again loaded the login graphic follows the command that worked for me here

sudo apt-get install - reinstall kdm

command executed in text mode and after that I gave the command shutdown-r now

restarted the pc back when the logon screen graphically thanks for the tip.

Eu tinha removido o tema ariya e atela nao carregava o logon grafico então aparecia uma msg assim: Não foi encontrado o tema /user/shared/kde4/apps/kdm/themes/ariya e eu dava ok então carregava no modo texto para fazer o logon com o comando informado aqui deu certo e carregou novamente o logon grafico segue o comando que deu certo aqui para mim

sudo apt-get install --reinstall kdm

comando executado em modo texto e depois desse comando eu dei o comando shutdown -r now

quando reiniciou o pc voltou o logon da tela grafica valeu pela dica.
