What display manager do you use? i use default sddm. it happened because my monitor's edid show 75hz as supported but it only support 60hz, kwin try to use 75hz and atomic modeset get failed and my monitor show black screen. this happend only with wayland session, x11 session works. please make any fallback mechanism so, instead of 75hz, kwin use 60hz. gnome shell's atomic modesetting works which means there is some fallback mechanism possible. there is a workaround, custom edid file with drm.edid_firmware= kernel parameter. if possible, please consider fallback mechanism. it is related to this, a fix was claimed but i still get same error and black screen. https://bugs.kde.org/show_bug.cgi?id=512146 -- You are receiving this mail because: You are watching all bug changes.
