Argent Software

The author of the machine is equipped with Redhat Linux7.2 operating system, installed the KDE and GNOME desktop, the only established at the time of installation in the super-user root, but the super-user privileges too, is only applicable to system maintenance and installation of software use, Should use the normal use of ordinary users to log. So it is necessary to create a new general users. This inverted also simple, open the %26quot;menu → → account management system%26quot;, adding a user does not have to! Could be trouble on the matter to: withdraw from the re-use after the root login, enter a password, ah! Wrong password, the system can not Jin.
