My laptop has become slower in boot time since the upgrade to Bionic Beaver.
Most of the time (about 30 seconds) is lost here, according to dmesg:
[ 3.376986] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio2/input/input10 [ 3.804388] [drm] RC6 on [35.544677] EXT4-fs (nvme0n1p1): mounted filesystem with ordered data mode. Opts: (null) [35.625669] ip_tables: (C) 2000-2006 Netfilter Core Team
With a nvme SSD, newly installed, it booted in 20 seconds. How can I find out what process uses the lost time? What does the time in brackets say, the startup time or time finished?
