    Phoronix: A Closer Look At Red Hat's Plymouth

    Back in July we shared Red Hat's intentions to replace RHGB with Plymouth, a new graphical boot process that is able to benefit from the latest Linux graphics capabilities. Red Hat engineers had primarily designed Plymouth around a forthcoming feature we've talked about quite a bit known as kernel mode-setting, which provides end-users with a cleaner and flicker-free boot experience. In September in The State of Kernel Mode-Setting we then shared more information on Plymouth along with a brief video. Most recently we published another video of Plymouth that shows the tighter integration between the boot process and starting the GNOME Display Manager. Today though we are looking at Plymouth and its different plug-ins along with providing a few more videos.

    Cruel world

    Why can't we have a flicker free, beautiful boot process that takes just 10 seconds to complete?

    I hate the fact that I need to wait 10 seconds just to reach grub! That's riddiculous!

    I want splashtop thingy with a full linux distro and a beautiful process like this Plymouth!

      well thats nothing linux can fix
      most mobos really need to show all of that useless stuff during the boot process...
      would be more usefull if you had the option to skip all of that -_-

        No! I want startup to be so quick that Plymouth isn't needed anymore!

          What kernel version is there in Fedora? %) I've read recently, that KMS is not included even into forthcoming 2.6.28...

            2.6.27. They just add in the KMS patches, etc.

              So, it's useful and wanted feature, and there is a working code. Why it was denied for inclusion into 2.6.28, then?.. :-(

                A lot of stuff still is buggy with KMS, and I think they also need to have a common api they can safely freeze, before they include it in the kerenel.

                The idea here is to keep from introducing too many changes that have the potential to break things at the same time. All the same, I would like to find some patches which could add KMS to 2.6.28 so I can set it up myself

                  "Having Plymouth will not lead Linux to having a greater market-share"

                  NEVER underestimate the value of SHINY.

                    Well, think in both things connected

                    You press the power button and then it fades from black to your desktop or login screen in a smooth animation

                    Instant boot + smooth graphics = Holy grail!

                      Yeah, and don't forget to turn display ON, only when you feel (won't even guess by what receptor) that kernel is loaded ;-)

                        Was just wondering if anyone knew of any way to force modesetting on for r200 series cards, specifically RV250
                        I believe they don't have it on because it breaks 3d; well the 3d isn't very good anyway...
                        so I want to try KMS and Plymouth.

                          The vga=0x318 is not necessary correct for vesafb. That one doesn't work on my system, for example. I can use 0x31A or any of a number of others.

                          The article also says that R600 works with KMS, but that doesn't seem to be the case yet (for stock Fedora/Rawhide, anyways). As stated on the Open Source AMD/ATI boards, that still requires building your own DRM and releated bits from the modesetting-gem branch of mesa/drm.

                          KMS in Rawhide definitely isn't working on R600 on my machine without using vesafb, anyways.

                            Add radeon.modeset=1 to the kernel command line for r100/r200s

                            R600 the code is there, the PCI IDs are not, I'll probably enable them in rawhide post-F10, it was just a matter of bad timing.

                              What about r300s/400s? If I understand phoronix's article correctly it's only enabled for 500+ series by default?
