Created attachment 112783 [details] Message screenshot 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 Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

I am facing same issue. For me it happens both way switching from nvidia to intel and vise versa.

Any updates on the issue? Still present on plasma 5.14
While the bug is different, a fix for bug 364593 should also fix this.
*** Bug 391857 has been marked as a duplicate of this bug. ***
We now have a software render fallback. Please reopen if still an issue after 5.15
