Lost "root" login in Fedora 22-KDE

Filed under
Others

I could use some help. My girlfriend recently installed Fedora 22-KDE and while "tweaking" her preferences and installing other programs has lost the option to login as root. She is able to login as root in a terminal, and if a program asks for root access, but not from startup???? I am at a loss as to how she screwed this up or how to fix it. Any help would be appreciated.

I don't know what display manager you are using.
If it is sddm, then edit /etc/sddm.conf and add MinimumUid=0.

If it is kdm, then edit /usr/share/config/kdm/kdmrc and change
AllowRootLogin=false to AllowRootLogin=true.

The location of those two files may be different on your computer. Typing 'locate kdmrc' or 'locate sddm.conf' may help.

If you can't find sddm.conf, you may need to create one (touch /etc/sddm.conf).

kdmrc should be installed by default.

Having said all that, you don't need to log in as root to KDE. In fact, even if you ignore the security risks and still log on as root, this may still break things because running a full KDE session as root can expose hidden bugs. Known bugs will also probably cause extra damage (expect dead unicorns and aliens abducting your kittens when you do so).

Login screen

kdm or gdm and the likes of them present which users can log in when starting a session (logging in as root is strongly discouraged for good reasons).

Have anything changes been made to the login screen or session manager?

When Diverse Network ASICs Meet A Unifying Operating System

And it has also been a decade since switch upstart Arista Networks launched its Extensible Operating System, or EOS, which is derived from Linux. [...] The cross-platform nature of ArcOS, coupled with its ability to run in any function on the network, could turn out to be the key differentiator. A lot of these other NOSes were point solutions that could only be deployed in certain parts of the network, and that just creates animosity with the incumbent vendors that dominate the rest of the networking stack. Given the mission-critical nature of networking in the modern datacenter, it costs a great deal to qualify a new network operating system, and it can take a lot of time. If ArcOS can run across more platforms, qualify faster, and do more jobs in the network, then, says Garg, it has a good chance of shaking up switching and routing. “That totally changes the business conversation and the TCO advantages that we can bring to a customer across the entirety of their network.” Read more

  • 9 steps to awesome with Kubernetes/OpenShift presented by Burr Sutter

    Burr Sutter gave a terrific talk in India in July, where he laid out the terms, systems and processes needed to setup Kubernetes for developers. This is an introductory presentation, which may be useful for your larger community of Kubernetes users once you’ve already setup User Provisioned Infrastructure (UPI) in Red Hat OpenShift for them, though it does go into the deeper details of actually running the a cluster. To follow along, Burr created an accompanying GitHub repository, so you too can learn how to setup an awesome Kubernetes cluster in just 9 steps.

  • Weaveworks Named a Top Kubernetes Contributor

    But anyone who knows the history of Weaveworks might not be too surprised by this. Weaveworks has been a major champion of Kubernetes since the very beginning. It might not be too much of a coincidence that Weaveworks was incorporated only a few weeks after Kubernetes was open sourced, five years ago. In addition to this, the very first elected chair of the CNCF’s Technical Oversight Committee, responsible for technical leadership to the Cloud Native Foundation was also headed up by our CEO, Alexis Richardson(@monadic) (soon to be replaced by the awesome Liz Rice (@lizrice) of Aqua Security).

  • Improving trust in the cloud with OpenStack and AMD SEV

    This post contains an exciting announcement, but first I need to provide some context! Ever heard that joke “the cloud is just someone else’s computer”? Of course it’s a gross over-simplification, but there’s more than a grain of truth in it. And that raises the question: if your applications are running in someone else’s data-centre, how can you trust that they’re not being snooped upon, or worse, invasively tampered with?
