I've got a really strange situation. I've been experiencing some memory leaks, and when I saw top report that I was getting dangerously low I used ctrl-alt-backspace as the quickest way of killing X. Up to now, when this happened I have always rebooted, but I hoped that by killing my session I might not need to reboot. I got to the login screen, gave my password, and it sat there at the default splash screen. I couldn't go any further. In a failsafe session I searched for LOCK files, but the only ones I found were in /etc/selinux/targeted/modules. I tried renaming ~/.kde, but exactly the same thing happened, and a new ~/.kde was not created. I can list all the files and directories in /home/anne and they are all owned by me. A second user account is fine, so I know that KDE as such isn't damaged. I'm completely out of ideas. What have I missed? Anne
