   Hi Paul, Marco,   
      
   it's normal boot, no sleep-mode or hibernate. Machine is a laptop /   
   notebook with docking station.   
      
   I just went into grub menu, now, selected "advanced options for Ubuntu"   
   ==> "Ubuntu with Linux 6.5.0-10-generic". ==> It prompts   
      
   "Loading Linux 6.5.0-10-generic ...   
   Loading initial ramdisk ..."   
      
   After that, it says that /dev/sda1 is clean,   
   and a few seconds later, graphics mode is active.   
   No systemd messages like "xxx target reached", "waiting for service yyy"   
   and so on are displayed as known from other distros.   
   Same behaviour when just booting without touching anything but even   
   faster.   
      
   Best regards,   
      
   Markus
