Title: Display manager shows only a black screen Status in linux package in Ubuntu: Confirmed Bug description: I've noticed that, since the update to kernel 3.19.0-23, SDDM only shows a black screen instead of the usual login screen. It, however, works flawlessly on 3.19.0-22. I've also noticed that the nvidia module is absent from lsmod in 3.19.0-23 onwards, but present in 3.19.0-22, and that is likely related, since I use nVidia GeForce GTS 250 graphics. Additionally, I've tried kernels from http://kernel.ubuntu.com /~kernel-ppa/mainline/ and have noticed that versions 4.0 onwards fail in exactly the same way I described, while 3.19.8 (the latest available 3.xx) works fine.
