Summary: Input device problems under Wayland
Product: [Applications] systemsettings Reporter: Johnathan Raymond <johnathan.raymond>
Component: kcm_mouseAssignee: Unassigned bugs <unassigned-bugs-null>
Status: RESOLVED DUPLICATE    
Severity: crash CC: kde, unassigned-bugs-null

Sentry Crash Report:

Description Johnathan Raymond 2019-03-12 18:29:04 UTC 
Application: systemsettings5 (5.15.2)

Qt Version: 5.12.0
Frameworks Version: 5.56.0
Operating System: Linux 4.15.0-46-generic x86_64
Distribution: KDE neon User Edition 5.15

-- Information about the crash:
- What I was doing when the application crashed:
Trying to launch Input device settings in System Settings under Wayland

- Unusual behavior I noticed:
External Input devices connected to Dell XPS DE over thunderbolt (Logitech G502 mouse, Rosewill RK9000, Dell TB16 dock) were not active in the Wayland session (No mouse or keyboard input), but are available in SDDM. When navigating to input device settings to debug, experienced this crash. Laptop integrated trackpad and keyboard are working.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
