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.

It would be interesting to compare it with the xrandr report of a running sddm.
