580.167.08 System freeze - external monitor - kde wayland - laptop - hybrid intel + nvidia

Hello,

I have a laptop Acer 7 A717-71G-531C. When I plug hdmi cable for an external monitor, each time that the mouse goes in the external monitor the system freeze and i can just reboot the system.

This issue appear only in a Wayland session. X11 session works.

I fixed the issue setting the variable KWIN_FORCE_SW_CURSOR=1 in /etc/environment.d/90-kwin-wayland.conf.

Spec:

  • Debian 13
  • Kernel 6.12.90
  • Nvidia 580.167.08
  • KDE Plasma 6.3.6
  • GPU 1: NVIDIA GeForce GTX 1060 Mobile [Discrete]
  • GPU 2: Intel HD Graphics 630 @ 1.00 GHz [Integrated]
