Plymouth Gets Tighter Integration With GDM, X

X.Org

For about two years now Red Hat has been working on the Plymouth project to replace RHGB with this graphical boot program that leverages kernel mode-setting and other newer Linux innovations to provide a clean, flicker-free boot experience. Over the course of the past few Fedora releases, Plymouth has continued to pickup new features and is also now being used by Mandriva. While Plymouth already does a great job at mode-setting to the display's native resolution and then showing the selected Plymouth plug-in and then to switch over to GNOME's GDM quite smoothly as the X.Org Server starts up, this process is getting even smoother now.

Committed to the Plymouth master code-base and a branch of GDM is support for very nicely handing off control of the display(s) between Plymouth and GDM. With the Plymouth code found in Fedora 12 and earlier, it sort of assumes and hopes that the X Server starts up nicely from where Plymouth left off, but if that doesn't go smoothly, the user is left in a troubled state. Now though this has changed where Plymouth receives a deactivation signal, which rather than just killing Plymouth, it leaves the plug-in idling on the screen until the X.Org Server takes over and is properly initialized. The GDM then signals to Plymouth when to properly shut itself off and is switched over to showing the X Server.

The new work that hit the Plymouth tree can be found in this Git commit, which was previously part of Plymouth's no-fbcon branch. The Plymouth integration work for the GDM can be found in the plymouth-integration branch. Lastly, Red Hat's Ray Strode who has been the principal engineer of Plymouth has written a blog post covering this nice Plymouth-to-X hand-off process.
