Nouveau with gdm loggin screen

This is an odd one. When Fedora boots (either 22 or 23), the logging screen is sluggish: I mean, press a key wait for two seconds to have something appear on the screen. Once I log in -- which takes longer than the machine booting up! -- the OS is super responsive and works as expected.

I run a VGA compatible controller: NVIDIA Corporation GM204 [GeForce GTX 970] (rev a1), with nouveau on Fedora 23. Dmesg provides these:

I've changed my display manager to kdm. gdm is simply broken for recent Nvidia graphics cards. Don't use it.

You can report the bug but don't expect it fixed soon because I suspect it's related to Nvidia Wayland support thus more upstream and Fedora's premature adoption of unfinished product.

I'm still quite amazed how someone actually makes Fedora 23 unusable from the very beginning login screen.
