James' openSUSE Bash Scripting (and other things) Blog - Your Comments are Welcome!

With the release of openSUSE 12.1, the SUSE specific KDM Login screen does not support a user listing. Apparently this was originally reported as a bug, but turns out this was done by design and some of our users have since missed this old feature. You can read about it and the proposed fix that was supplied here:

https://bugzilla.novell.com/show_bug.cgi?id=727821

What I have done is to snag the new openSUSE.xml file written by Hendrik Müller and posted it into SuSE Paste here: openSUSE.xml

And I wrote a bash script that can fetch the xml file, rename your old xml file and use the new one. Just log out to see your new user listing. If you should change your mind, just run the script again, but with the -r option and the original openSUSE.xml file will be restored. Here is the bash script for your consideration:

Code:

#!/bin/bash

# End Of Script

Just copy the text in the code block above, into a text editor like kwrite and save it into your local ~/bin folder as the text file make-kdm-user-list (/home/yourname/bin/make-kdm-user-list). To use make-kdm-user-list, you must mark it executable.

Open up a terminal session and run the following command:

Code:

chmod +x ~/bin/make-kdm-user-list

To use the script, open up a terminal session and run the command:

Code:

make-kdm-user-list

When you run make-kdm-user-list, you will be asked if you wish to download and replace your old openSUSE.xml file. If you agree, a backup of this file will be made for you. If later, you change your mind and wish to return to using your old openSUSE.xml file, just open up a terminal session and run the following terminal command:

Code:

make-kdm-user-list -r

For this whole thing to be useful, you need two or more users in openSUSE, a function in YaST. In the KDE Personnel Settings / Login Screen / Users Tab / User Images, you can assign each user an icon if you wish.

If you have any questions or comments about this script, just let me know.
