OS: KDE Neon 5.12
Plasma Version: 5.12.5
KDE Framework Version: 5.46.0
Qt Version: 5.10.0
Kernel: 4.13.0-41

Laptop: Dell Inspiron 3558
Driver: nvidia-384
Card: Nvidia Geforce 920m

This bug has been previously reported multiple times and has the status
resolved downstream, but I am still encountering the bug.
Might be possible because I am using the newer nvidia-384 driver.

Steps to reproduce:
1) Open terminal
2) sudo prime-select nvidia
3) Try to log out
4) ksmserver-logout-greeter crashed message comes up.

Backtrace result:

Application: ksmserver-logout-greeter (ksmserver-logout-greeter), signal:
Aborted
