The Graphical Login Screen. Three graphical login screens are available for Fedora 11. In this video I just illustrate each of these screens and the options available therein. First, the simplest way to modify a login screen for a system is through a text file: etc/x11/prefdm. For this video I've opened it up in a console, but you can also open it up from a GUI Command Line based on the root account using the G Edit Editor, which I described in a different video. Note the preferred line early in this file. Normally it's set to equal nothing. I've set it to equal KDM, which would be the KDE Display Manager. If I delete that it goes back to the default GNOME Display Manager and these are the three different display managers that are available, the third one being the X Display Manager, or XDM. If you want to know more about the mechanics of how a display manager is selected during the boot process look up information on Upstart at the URL shown here. Now let's look at examples of each login screen. First the default GNOME Display Manager shown here. First, if you click this Icon, or let's cancel out of here, and we click this Icon which gives us the Universal Access Preferences Window. We can open up an onscreen keyboard or do other things that can help those who are visually impaired. I assume you're not visually impaired so I close out of that window, and next I select a User Account Name. Note the options opened up down here. I can select from different languages. Only English is available because I've only installed American English on my system. You can select from installed keyboards, and also you can select from available and installed Desktop environments. I select a Desktop environment and then enter my password. I can then log into the local system. Now let's look at a KDE Display Manager shown here. The look is somewhat different. It's not quite as functional as the way Fedora has configured the GNOME Display Manager but you can still select from the different configured users on the system and also you can select different options based on what's available from the buttons. For example, I click the green button and I can log into different Desktop environments. If I click the yellow button I can do other things like restart the X Server, log in to a remote system, or even shut down the local system. Finally the X Display Manager is the simplest sort of login screen as all it allows is a login and a password. Backing up a bit from the GNOME Display Manager screen you are able to select different Desktop environments but you can set a default GUI Desktop environment with the Switch Desk Tool. And I've set it up on the screen here and you can select it with the System Preferences, Desktop Switching Tool Command, which allows you to switch between default Desktop environments. Well, those are the options associated with Graphical Login Screens.
