Bug ID: 462198
Summary: kwin_wayland crashes after unplugging external USB-C
monitor and closing the laptop lid
Classification: Plasma
Product: kwin
Version: 5.26.0
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: wayland-generic
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
My Wayland session crashes when I close the laptop lid, but only after I have
unplugged my external monitor, connected through a USB-C dock.
This happens every time I try.
Sometimes it also crashes when I plug the monitor back in.
***
Will update when I can
***
STEPS TO REPRODUCE
1. Plug in USB-C dock with external monitor in HDMI port (or boot up with the
external monitor connected)
2. Unplug the USB-C dock
3. Close the lid (or have it closed while unplugging the dock)
4. Open the lid, if you're fast enough you'll still see the terminal before
kwin_wayland restarts itself
4a. Note, the session itself is still live, so no need to log in again using
SDDM.
4b. If I have the lid closed while unplugging the screen, the session is locked
like it is supposed to.
In the other scenario, it isn't.
OBSERVED RESULT
kwin_wayland has crashed, taking all applications running on top with it.
EXPECTED RESULT
Locked session, and all my application are still running
