Fedora 27 Screen Saver
Just back from Oracle OpenWorld and somebody desperately wants to know how to disable the 5 minute default screen saver setting in the KDE environment. OK, you navigate to the Fedora “f” in the lower left hand corner and choose System Settings, like:
In the System Setting menu page, select Desktop Behavior:
In the Desktop Behavior dialog, select Screen Locking. Change the default to something large like 90 for 1 and half hours.
As always, I hope that solves your problem.
Fedora User Manager
As one of my students pointed out, Fedora doesn’t install a GUI user management tool installed by default. That’s true. It’s easy to install. You can install it as the root
user, like:
yum install -y system-config-users |
It should generate a screen console output like this when successfully installed:

You can verify the GUI user management tool is present with the following command:
which system-config-users |
It should return this:
/bin/system-config-users |
You can run the GUI user management tool from the root user account or any sudoer account. The following shows how to launch the GUI User Manager from a sudoer account:
sudo system-config-users |
It will generate the following GUI User Manager screen:
As always, I hope this helps those trying to do some that should be a basic task that seems to get lost form the books and manuals beginners use.
Linux User-Group Console
This post shows you how to add the menu option and GUI to set users and groups. It’s quite a bit easier than mastering all the command-line syntax. It makes setting up the required user and group accounts for an Oracle Enterprise or MySQL database solution much easier.
You add the utility by calling the yum (Yellowdog Updater, Modified) utility like this:
yum installed -y system-config_users |
You should see the following:

After successfully installing the radian
, rarian-compat
, system-config-users
, and system-config-users-docs
packages, you will find that there’s now a Users and Groups option when you navigate by clicking on Applications and then clicking on Sundry from the menu.
Menu Instructions
- You navigate to the Applications menu, and choose Sundry from the menu list and Users and Groups from the menu item to continue.
- You will be prompted for the sudoer’s password in this dialog.
- At this point, you can use the GUI interface to set users and groups.
As always, I hope this helps those trying to set users and passwords without mastering the command-line syntax.
