Bug ID: 499921
Summary: Wayland session logs out when external monitor is
connected (NVIDIA, Plasma 6.3)
Classification: Plasma
Product: kwin
Version: 6.3.0
Platform: Neon
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
- Description
I am experiencing an issue with Plasma 6.3 on Wayland when using an external
monitor with my NVIDIA GPU. If I try to start a Wayland session with the
external monitor connected (via DisplayPort), the screen flickers, and I am
immediately sent back to the login screen. If I connect the monitor after
logging in, the session crashes and returns to the login screen.
This issue does not occur under X11, only in Wayland.
-Steps to Reproduce
Boot the system and attempt to log in to a Plasma Wayland session with an
external monitor connected via DisplayPort.
The screen flickers, and the session fails to start, returning to the login
screen.
Alternatively, log in to Plasma Wayland without the external monitor.
After logging in, connect the external monitor via DisplayPort.
The session crashes immediately, returning to the login screen.
- Expected Behavior
Plasma Wayland should handle the external monitor without crashing or returning
to the login screen.
