After installing Knoppix 3.6 on my laptop, knoppix was working fine till one day I ran out of space .
I created new extended partition on free space using qtparted as I had about 60% disk unused. After that I am not able to login to KDE as normal user. I can login as root and changed password for normal user but when I logout and try logging in using login screen , when I select another user and try logging in, it does something and shows me login screen again.
If I enter wrong password, it immediately says login failed but on correct credentials, keep on getting login screen again and again
Pls. help
