Now, maybe I’m too old-skool, but that’s just plain irritating. Here's how to enable root logons in Kubuntu.

Edit the kdmrc file

The first thing you need to do to enable root logons in Kubuntu is to modify the/etc/kde3/kdm/kdmrc file. However, to change this file - guess what? - you need root access! Here’s how to do it:

1. Press alt+F2 to call up the Run Command. Type in /etc/kde4/kdm to call up the kdmfolder in Konqueror.
2. When the folder opens, you should see a file called kdmrc. Right-click it and selectActions, Edit As Root. You’ll be prompted for the root password (which should be your own password)
3. The file should open up in a text editor (KWrite on my installation). Broswe for the lineAllowRootLogin=false and change false to true. Save the file and close it.

Enabling Root Logins (Modifying the Root User Account)

The second step here is to actually enable the root account for login, because it is disabled by default. There may be a quicker, more linux way to do this, but this is my method:

1. Press alt+F2 to call up the Run Command. Type in kuser to start up the KDE User Manager.
2. Double-click on the root entry to bring up the account properties and uncheck theAccount Disabled checkbox. Click OK to save the changes.
3. Exit the KDE User Manager.

And that’s it! If you log off, you should now be able to login to Kubuntu as root.

Why Enable Root Logins?

Yes, I know that in an ideal world I would use sudo. Why did I absolutely require root access? Well…

1. I don’t know Linux very well. I can hold my own, but I don’t speak the command-line-lingo like the pros.
2. Elements of the GUI in Kubuntu don’t work so well. In particular, the network configuration utility ‘forgets’ the default gateway entry.
3. Some graphical tools also have an Administrator Mode button. I found in some instances that this didn’t work. You would type in credentials and it would return you to the same greyed-out screen, indicating that authentication had been rejected. Very frustrating.
4. Being fairly unfamiliar with Linux, I didn’t know the command equivalent for these graphical functions, so I couldn’t very well sudo them, could I?
