This has started to happen after I encrypted my home folder (this was done after the installation, not as a part of it)... This was in 11.10. I have since upgraded to 12.04 and after first reboot everything worked well. However since reboot after this, the messages started to pop up again before the actual KDM login prompt. I am using Kubuntu 12.04 and I have tried different things such as permissions 777 for /tmp, removing everythign from /tmp or even deleeting ~/.kde or ~/.Xauthority etc. Reproducible: Always Steps to Reproduce: 1. Boot 2. Messsage appears (X style - black and white) - click OK 3. KDM starts, i am able to login Actual Results: error before kdm login screen Expected Results: kdm login screen or if autologin enabled, then skip to locked session in KDE
likely means your config files in /etc/pam.d are wrong (as in: your encrypted home partition is not mounted)
How do I go about fixing that? How does clicking on OK change the situation and allows KDM/KDE to start?
