In this course, you will move from being a Linux ''user'' to being a Linux system ''administrator''. == Tips == Tips and suggestions:* Always shut down your system under software control, rather than using the reset or power buttons. You can shutdown using the GUI or with the <code>poweroff</code>, <code>reboot</code>, <code>init</code>, or <code>shutdown</code> commands.* If you get a message about the gnome-power-manager configuration at the login screen, you may have run out of disk space. Take a look at the available space (with <code>df -h</code>). If the <code>/</code> filesystem is full, delete some files (such as unused VM images in <code>/var/lib/libvirt/images</code>) and then reboot the system.* If your system is becoming very slow periodically, it is probably due to a known issue with the Intel video driver, kernel, and NICs. See [https://bugzilla.redhat.com/show_bug.cgi?id=523646 Bug 523646] on the Fedora Bugzilla system. Apparently kernels 2.6.32.7-37 and higher (currently in testing) fix this issue -- so use 'yum update' regularly and watch for a new kernel update shortly.
