Version: (using KDE 4.3.0)
Installed from: Fedora RPMs
This is a wish: probably it will not be fixed sometime soon, but this helps to keep track of the status of the work and to collect possible votes for the feature.
Kernel Modesetting drivers are becoming more and more widespread (most of the major distributions will enable it), but at the moment smooth transition between Plymouth and KDM isn't implemented, so one of the features of KMS itself gets lost.
As stated here:
team work is needed between KDM and Plymouth.
Interesting article about Plymouth, X and GDM; it explains several things:
The first 2 steps @ making this work:
1. start X using (new/undocumented, grr...) -nr option, to not clear screen on startup
2. patch kdm to use the current/active vt (instead of what's specified in kdmrc). Also, quite fugly.
3. todo: for polish, offer an animated transition from plymouth background to kdm one.

kdm to use active vt when using plymouth
code lifted from fedora 12's gdm package. patch against 4.3 branch.
newer patch now here: http://cvs.fedoraproject.org/viewvc/devel/kdebase-workspace/kdebase-workspace-4.4.2-kdm_plymouth081.patch?revision=1.2&view=markup
it's sorta suboptimal and excessively verbose, but it looks sane in principle.

Is it in Fedora 14 and / or any other distro? Is there something missing to merge it upstream?
Yes, it is in Fedora now. Installed Fedora 14 KDE Live CD and with nouveau I can see the transition, i.e. Plymouth background s there when X starts. The cursor appears right over fhe "f" logo. So this patch got accepted in Fedora (not upstream though, it seems) and the bug can be closed as no distros apart from Fedora now implement the Plymouth KMS feature. (KUbuntu comes to mind, I know that Ubuntu now uses Plymouth or was going to use it, don't know about KUbuntu though)
I think the bug can be closed only when the patch is applied to KDM.
So what do you think Oswald? can we have this patch applied for KDE 4.6? would be awesome.
Will this feature be in 4.7?
I'm waiting for this, too. Using Gentoo and Arch Linux.
I've applied the patch from #5 to KDM that comes with 4.6.3, but it doesn't work. The transition still doesn't happen correctly.
Altering kdmrc and appending -nr to ServerCmd results in X not starting. "-nr" is not a valid option. (X.Org server 1.10.1.)
So how is this supposed to work? I'm on Gentoo, if it matters.
-nr option is no longer valid. Append "-background none" to ServerArgsLocal= in kdmrc.
Have it working flawlessly on ArchLinux with systemd as init.
What is the status of this patch getting upstream in KDE?
As more distros switch to systemd and/or plymouth this would be very nice to have. (Rebuilding kdebase-workspace is at least a 30+ minute compile even on newer machines).
Two years after patch was made and this bug is still without any feedback from KDE devs? Oh, c'mon guys!

Revised KDM <-> Plymouth interoperation patch
Attaching a revised Plymouth interoperation patch against 4.11.2, based on Ubuntu's one.
- VT override
- Plymouth talking (`deactivate` and `quit --retain-splash`)
- X server option `-background none` to avoid painting black over the splash remains
Any chance this can be applied?
