I did not expect a significant difference in the time needed to reach the login mask of LightDM. 4) What happened instead The time needed to reach the login mask of LightDM depends on the bluetooth status. When bluetooth has been turned off in a previous user session per blueberry tray icon, a black screen with only the mouse pointer in the center is displayed for ~6s before the LightDM login mask is displayed. This does not happen, when bluetooth is turned on or when the older kernel 4.15.0-124.127 is used to boot the system. Kernel 4.15.0-124 AND bluetooth turned on or off => normal boot time Kernel 4.15.0-128 AND bluetooth turned on => normal boot time Kernel 4.15.0-128 AND bluetooth turned off => 6s longer boot time I did not have these problems before the upgrade to kernel 4.15.0-128.131. And I do not have these problems on my desktop system, which lacks a bluetooth card.
