Kde black screen after boot

[sina_rajabpour]

hi, i have this issue since the installation.when i turn on the system, sometimes after showing the asus logo , the system does not load the desktop and shows a black screen without mouse cursor or type pointer. then when i restart the system by physical key, it loads just fine. i tried the Ctrl+Alt+F2 and F1 and etc… in black screen with no luck. also i pressed ‘e’ in grub and added ‘nomodeset quiet splash’ , when it boots stuck on ’ [“… clean, … files, … blocks”]’ and nothing happen (also tested ''nomodeset i915.modeset=0 nouveau.modeset=0 same result).

• using nvidia GM108M [GeForce 930MX] with intel integrated

Hello @sina_rajabpour

@sina_rajabpour

sometimes after showing the asus logo , the system does not load the desktop and shows a black screen without mouse cursor or type pointer.

To point you in the direction: It could be possible that the system starts too fast, so that the GPU is not ready and the display-manager does not wait for the gpu to become ready… It is an issue with gdm and lighdm sometimes.

Possible that the issue effects now sddm also by a cold start. You could try to add some extra time at the sddm service like the gdm service explained at the link above.
