Cannot login after upgrading to kde 3.4, brings me back to login screen
I am running Mandrake Linux 10.1. Everything was running fine until I decided to be bold as a newbie and upgrade to kde 3.4.
I downloaded the rpm file, telinit 3, urpmi kdebase.
After the install I rebooted and it brings me into the login screen. I have lots of users to choose from which is new. Rather than just my normal user admin I have about 15 more adminsu, root, mail etc.
I choose the normal two either admin or root type my password and hit enter and it makes the screen black and bring me straight back to the login screen. The only other two buttons are reboot and halt of which clicking either does nothing.
I am completly stuck can anyone direct me.
Many thanks for any help.
