Can't open another graphic session (can't switch user)


When I go to Menu -> Leave -> Swicth User (that’s open a parallel session as a different user) what happens is:

The actual session is being blocked.

What is supposed the system have to do:

Leave the actual session open and display the log in screen.

Any ideas why is happening this ?

Not without some information about your system - what version of openSUSE,
what desktop environment, etc.

I am finding this is working for me using KDE 4.8 (KDE 4.7 comes with openSUSE 12.1 by default). I had to do the following to test this out:

  1. Got YaST / Security and Users / User and Group Management / Create a new user
  2. Log out of KDE
  3. Enter new user and Password, make sure to select a default session type, like KDE Plasma Workspace if this is a new user or you upgraded to KDE 4.8
  4. Once the Desktop is loaded select KDE menu / Leave / Switch User
  5. If no other users exist yet, select a New Session
  6. Enter a different User name and password and again make sure to select a default session type, like KDE Plasma Workspace if this is a new user or you upgraded to KDE 4.8
  7. After the Desktop is loaded now you can select KDE menu / Leave / Switch User and the first user entered should be there to select.

So its working for me under KDE 4.8 and the User Must already exist and have a default session and this is not Gnome that was tested.

Using OpenSuse 12.1, with Kde (recently installed, yesterday, on July, the 7th) (Maybe is an update)

I don’t know what more information I can give.

Hope this helps

With the new user I have now 3 users (not counting the root)
I did step by step, but in the new user when I choose Switch user, the session blocks and I can’t change user.

Thanks, anyway.

There is no need to use another user (let alone create one for the purpose) to test this feature. As the OP says, he wants to see a login screen. If he will use it to login or login with the same user is not part of the problem and thus no need to test it.

I have openSUSE 11.4 and KDE 7 running, thus my contribution is not to be taken too serious (did it many times, also with older levels). When I click the Change user from the Main Menu > Abandon/leave system (do not have the English here), I get a small window which will show me the other running sessions (when there is but one it is empty of course) and an option “New Session”. When I click “New session” my own session is locked and after a short while I get a login screen. That is IMHO how it should work (it may be possibl to configure the session locking out somewhere).

By definition Switch User means to log in as a different user and further I could not recommend to log in as your self twice. The step by step shows how one might do it, how I did it, what you might expect, the desktop being used (could be a bug with KDE 4.7 perhaps) and the fact one needs to have a default session to switch to for each KDE user. If you go through the complete procedure as a test, you can then provide them to someone else with confidence they will work. At least this is how I do it.

Thank You,

I’m not opening another session with the same user, it’s a different user. And before this installation of opensuse works so well, I don’t knwo what is wrong.
Even my log in screen looks very different as before, but this I don’t know if it has something to do with the switch user issue


I just need to establish you can log in normally as any user, can log out and log back in as a different user and that you are using KDE 4.7 or 4.8. When you say the log in menu looks different, does it now always look different or only when you try to switch users? Finally, we may establish it could be a bug with KDE 4.7 and worth an update to 4.8. If the Log in menu looks different, how might we see what that difference looks like or at least describe that different to us? I often cheat with this using a VirtualBox session to capture such screens. Many other resort to using a digital camera picture of the monitor which works for me if you have one. You can use SUSE Paste and switch to image mode. This works well with Firefox and may not with Chrome.

Thank You,

Well, first of all I don’t know which KDE version I’m using. any clue for that ?
Log in screen looks different, every time I turn on the computer. (In switch user, there’s no log in screen because I can’t switch users, which is the main issue here)
After this installation of opensuse 12.1, the log in screen had a green background and 2 fields, one for user, the other for password, and show “opensuse” somewhere in the screen, and when I enter my password, for each letter I digit, a black dot appears in the password field.
Now, the screen is gray, graphic too, but gray. I named this computer as ‘agunet’. In the top show’s “Welcome to agunet”. And when the screen starts only user name field is displayed, after enter the user name and press enter, then the password field is displayed. And in this case, no black dots are displayed, instead a space is displayed for each letter I enter.
I hope his information helps. (except for the KDE information, I don’t where I can got it)

I know which version of KDE I’m using. It’s the KDE 4.7.2 “release 5”. Now I have to know how I can update the kde to 4.8

Before you do that you should change your login manager, maybe that is
the cause of your trouble. Your description sounds as if you have no
longer kdm but xdm as login manager.

Open yast->software management and search for kdm, check if it is
installed, if it is not, install it.

Now open yast (not the software management) and select system, in system
click on the /etc/sysconfig editor

On the left side you see a tree
Desktop -> Display manager -> DISPLAYMANAGER
in the right window enter kdm into the selection field and click ok.

Now you should be back to use kdm.

When trying to fix this problem, the system suddenly, didn’t recognize any user/passsword, so I installed open suse all over again, and now switch user is working fine.

Thank you all for all your answers.


Hm, not a very satisfying solution. Something was borked and when you do not know what it was, you can repeat the same.

I totally agree. Was a no satisfy solution. But, what else can I do ? I couldn’t enter to any user to get forum help. Well… what matters now, is that is working.
