After the upgrade the only way to kde work is executing /etc/init.d/xdm restart. If i execute xdm start, results in black screen.
Any ideas?

I experienced the same in Neon.

When you have configured your displays you have to hit the default button, then you can reboot and settings stay as they are.
EDIT: I see there is also a bugreport; but this fix did work for me, will report it @kde


Good luck :)

Hello.

Add sddm to the video group. That should work.
Code:
usermod -a -G video sddm

Please check that /etc/sddm.conf exists.

Yes, sddm.conf exists and is configured for autologin, but the screen goes to black on the boot.
Then, as root, executing /etc/init.d/xdm start, the screen remaim black. But if i comand
/etc/init.d/xdm restart, then the kde works. Maybe some bug?
The sddm is on the video group as recommended bye the upgrade manual.
