Hello,
I’ve got a fresh install of Lubuntu 20.04 (I just switched from a few years on Mint and am currently trying more lightweight distro) and I’m quite happy about it.
The only thing that puzzles me is a bit longer time the boot seems to take to decrypt my disk on startup. I chose the full encryption option during install on my SSD NVMe Samsung disk and it takes around 20-30 seconds from acknowledging my disk encryption password at startup to actually start proceeding through usual grub stuff (I removed quiet and splash from options for visibility). The same stage took merely a couple of seconds on the same setup under Mint I had a few days back. Actually I’ve made the current measurements:
orkan@gram:~$ systemd-analyze
Startup finished in 3.612s (firmware) + 24.503s (loader) + 6.508s (kernel) + 8.545s (userspace) = 43.169s
This isn’t the end of the world although I’d like to understand. A bit of googling told me that the number of encrypting iterations has something to do with that extended time and this is an option that Calamares controlled during install. I’m happy to dig into configs and such, but probably would need a punch in the right direction where to look. If there is a way to reduce that time it would be perfect although it’s OK for me at this stage to perform the install all the way from the scratch.
I’m attaching the logs underneath coming from the following commands:
416 [2020-05-24 16:47:59] sudo lsb_release -a
417 [2020-05-24 16:48:14] sudo lshw

419 [2020-05-24 16:48:46] sudo lsusb
420 [2020-05-24 16:48:54] sudo lspci
This is my first post on this forum. Many thanks for any advice.
Orkan.
