    Remove Gnome option from KDM Login Screen

    To all,

    I just got a new laptop with 12.10 on it, so I gave my wife my older laptop with 12.04 on it. She really likes it, but occasionally when she logs on she gets a "Gnome Desktop not Available" error and is kicked out to a command prompt. This does not happen all the tme, but often enough where she is concerned that there is something wrong with "Linux." I do not have Gnome installed on the laptop.

    What I think causes this is that I tried to install Lightdm a while ago--it didn't work out but it did seem to install a lot of Gnome dependencies. I stripped out lightdm with "apt-get remove --purge lightdm" but the problem seems to persist. I even did a search for other lightdm components and removed them, too.

    Is there any way I can disable/remove the Gnome option within KDM? I suspect that periodically the "default" is set to Gnome and that is causing the problem.

    Any ideas?

    Do you have 'gnome-session' and/or 'gnome-session-fallback' installed? These will put gnome .desktop files in /usr/share/xsessions/

          What's the output of:
          Code:
          ls -al /usr/share/xsessions

              It appears that when installing LightDM via
              Code:
              sudo apt-get install lightdm
              APT will choose the Gtk-based greeter by default, which pulls many GNOME packages. A better way to do this instead is:
              Code:
              sudo apt-get install lightdm-kde-greeter
              which will install LightDM and the KDE greeter all in one go.

                    A lot of that we can ignore. As I don't have KDM on any of my machines anymore, I'll have to keep asking you some more questions.

                    What's the output of
                    Code:
                    ls -al /etc/kde4/kdm/sessions

                      Here is it

                        Well, I'm out of ideas.

                        Anyone else here using KDM and multiple desktops, and can think of which configuration files might be borked on Thiudans's computer?
