No desktop up to 15 seconds after login
I was worried that my computer could be compromised and my login session is being hijacked by some malicious hook.
In .xsession executed by xdm, I capture a pstree snapshot a file to debug this situation.
This file's timestamp shows five to fifteen second delay after X11 login!
.xsession-errors doesn't show anything weird, only that I'm being added to "access control list" and then a couple of environment entries reported by dbus-update-activation-environment with no timestamps.
dmesg during this weird pause:
r8168: eth0: link up
IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
random: crng init done
random: 7 urandom warning(s) missed due to ratelimiting
audit: type=1400 audit(1546022714.845:26): apparmor="STATUS" [...]
bridge: filtering via arp/ip/ip6tables is no longer available [...]
Bridge firewalling registered
Initializing XFRM netlink socket
IPv6: ADDRCONF(NETDEV_UP): docker0: link is not ready
IPv6: ADDRCONF(NETDEV_UP): br-f14696ee8bfd: link is not ready
Regardless of the root cause (I suspect something demands more randomness after boot), how such problems can be debugged further?
Can I leverage systemd for example?

You can also look in /var/log/Xorg.0.log and search for "EE".
But there might be something going on in the system that wouldn't be reported in either of those. Try this right after you finally get logged in. The -e switch jumps to the end of the log, so start paging up looking for errors.
journalctl -e
My laptop has a problem similar to what you described, but in my case it's a known problem. I see this in the log, with the first line displayed in red. If you see something similar, you can search the bugzilla for your distro to see if it's been reported.
