Root User in Ubuntu: Important Things You Should Know

In Linux, there is always a super user called root. This is the super admin account that can do anything and everything with the system. It can access any file and run any command on your Linux system.
With great power comes great responsibility. Root user gives you complete power over the system and hence it should be used with great cautious. Root user can access system files and run commands to make changes to the system configuration. And hence, an incorrect command may destroy the system.
This is why Ubuntu and other Ubuntu-based distributions lock the root user by default to save you from accidental disasters.

| Nouveau X.Org Driver Sees First Release In Two Years
Two years and nine patches later, xf86-video-nouveau 1.0.17 is out as the latest X.Org driver update for this open-source NVIDIA driver component.
Like the other DDX drivers with the exception of the generic xf86-video-modesetting driver that is quite common now to those still running on X.Org with the open-source stack, xf86-video-nouveau seldom sees new activity. Since the prior v1.0.16 release two years ago there has been less than a dozen patches for it. The interesting activity happens in DRM/KMS kernel space and an increasing number of users are just relying upon xf86-video-modesetting over these hardware-specific X.Org user-space drivers.
