When I try to use kwin_wayland 5.25.2, it stalls with a black screen. Is there a better way to debug this?

At this point, I have to ssh on the laptop and kill kwin_wayland and I get the following:

Code: Select all


kwin_wayland_drm: Removing output KWin::DrmOutput(0xb2c820, name="DP-2", geometry=QRect(0,0 3840x2160), scale=1)


So it's detecting correctly the displays, but it only activates the backlight, but the screen remains black. Maybe it's because of the following line?

Code: Select all


kwin_wayland_drm: Failed to create gamma blob! Invalid argument


Any hints? Thanks!
