Hi,My Dell XPS 13 has always been very slow to boot and I just put up with it because I use my desktop PC for most serious work. However, I stumbled across an article in a magazine which informed me about systemd-analyze, so I tried it. Here is the output: terry@XPS-13:~$ systemd-analyze critical-chain The time after the unit is active or started is printed after the "@" character. The time the unit takes to start is printed after the "+" character. graphical.target @56.633s └─multi-user.target @56.633s └─smbd.service @56.563s +69ms └─nmbd.service @6.501s +50.060s └─network-online.target @6.470s └─NetworkManager-wait-online.service @1.822s +4.647s └─NetworkManager.service @1.684s +136ms └─dbus.service @1.679s └─basic.target @1.581s └─sockets.target @1.581s └─snapd.socket @1.574s +6ms └─sysinit.target @1.569s └─systemd-timesyncd.service @1.157s +411ms └─systemd-tmpfiles-setup.service @1.123s +30ms └─systemd-journal-flush.service @930ms +189ms └─systemd-journald.service @139ms +724ms └─systemd-journald.socket @137ms └─system.slice @134ms └─-.slice @134ms As you can see, the culprit seems to be nmbd.service; over 50 seconds compared to the next worse item of 4.6 seconds. This laptop is running Kubuntu 19.04 as is the desktop. I am aware that nmbd (and smbd) are related to samba and I previously setup a samba server on the laptop to assist with sharing files but I don't currently on the desktop (I used to share my directories on the desktop, but I did a clean installation on the desktop because of a bug in qt). It is still useful to have samba, but am unsure why the nmbd service takes so long. Any ideas?
Ran it on my Desktop, running Kubuntu 18.04, with this result: peterm@peterm-MBB-34204H:~$ systemd-analyze critical-chain The time after the unit is active or started is printed after the "@" character.
