I have just installed the Linux distro Pardus, with its KDE desktop. I already had a home directory(on a separate /home) partition so I just created the user and tried to logon. The problem is, when I log on using KDM, noe of the KDE stuff works, no desktop, no bars etc., only one xterm without any decorations. When I try to launch any X11 application, I get "cannot open display %s" while my $DISPLAY is :0
I renamed my home folder and created an empty one, that worked perfectly. So I have at least one dot-file that breaks my desktop settings. I have no .kde or .kde4 folders. All the ideas on what might be breaking my desktop is welcome. I was previously using Gnome desktops so I have fairly big .config, .gnome, .gconf etc directories.
