The same : a black screen with external monitor led going off. If I
press ctlr-alt-f1, led goes back up and I can login on console. I
switch back to kdm via dpkg-reconfigure and reboot.
Interesting.
kdm knows how to proceed with external monitor when sddm does not.
Period. So its a bug that for me render sddm totally unusable.
kdm and sddm are completely different beasts, but afaik neither have
specific code for handling an external monitor. Also, this nagging about
kdm is not productive, if you don't care about working on this issue,
please switch to a different display manager.
When you say its a bug in the nvidia driver that is also counter
productive and annoying for me because without external monitor, the
same drivers, same version same everything (except as said external
monitor) works well with sddm on other laptop. I use kdm example just to
say that the driver is not at fault. I just want to have sddm working
but see no progress and on my side, there is not much I can do as I have
no graphical environment at all as soon as I switch to sddm as a launcher.

It would be interesting to compare it with the xrandr report of a
running sddm.
I cant' : I probably have no X session running. I have a black screen
remember... Can try specifying display explicitly on console.
Can try to open the lid to see if anything is there but I doubt.
