Kde 3.4 - no root login

when upgrading to kde 3.4 you may lose the ability to log in as root, to fix this do the following:

open file manager super user mode

enter root password

go to /etc/kde/kdm

click on file kdmrc and it will open in kwrite

select edit > find

in the text to find box type allowrootlogin and uncheck case sensitive > click find

change the word false to true

it should now look like this AllowRootLogin=true

also check the section beginning [X-*-Greeter] if you have an entry HiddenUsers=root just delete the word root so it reads

save and exit, when you next reboot root login will be shown
