I maintain both the nvidia packages and nvidia-prime. What nvidia-prime
does is provide a way to use hybrid graphics (Intel+NVIDIA) in Ubuntu.
While I don't recall dropping he alternate dependency on sddm (which is
entirely possible that I did), maybe sddm doesn't really work with
If you want hybrid graphics to work (as it does in Ubuntu), you'll need
support for something like the following stanzas from lightdm:
The first line is executed after X starts, whereas the second line is
executed after stopping X (and before starting a new one).
Does sddm support that?
I should also modify the relevant upstart job in ubuntu-drivers-common
(the systemd unit already works).
