When I start my laptop, a blue screen with Kubuntu logo keeps loading for long time before the login screen appears. Because of that, boot time increased significantly. Is there any way to remove that logo screen or reduce time for appearance of that logo before login screen appears?

After I provide my credentials on login screen, Its normal. Only issue is with the blue logo screen which appears before login screen and stays for long time.

I am using Kubuntu 18.04 LTS with Plasma Shell 5.12.7.

Please find my boot.log file here: https://send.firefox.com/download/c0cc9425127d944b/#xy3FpDkqRCLPOLyWSwxjyQ

navi@navi-ubuntu:~$ systemd-analyze

  • This is really not a bad time for boot. One process, systemd-journal-flush is taking a while, and you might examine https://askubuntu.com/questions/1094389/what-is-the-use-of-systemd-journal-flush-service Jun 10, 2019 at 19:26

Looks like boot process gets stuck on something. Contents of /var/log/boot.log might help. File can be viewed only with sudo privileges.
