Slow Linux? Let me a-fix it for you. Here's a long, detailed tutorial explaining how to troubleshoot slow boot issues in Ubuntu following an upgrade from 16.04 or 17.10 to 18.04 due to wrong swap device UUID used in /etc/fstab, including systemd analysis and critical chain, disk speed checks, initramfs updates, wrong resume device, disabling services, journal flush, post-boot slowness due to readahead messages, one-time issues with Intel graphics and SDDM, other tips and tricks, and more. Have fun. https://www.dedoimedo.com/computers/ubuntu-beaver-slow-boot.html Cheers, Mrk
