Comment 17 for bug 1763611

@ volker kempter (v-kempter),

Thanks for never giving up and finding that question/answer at AskUbuntu :-)

You are right! I did some checking, and there was also a warning, when running

sudo update-initramfs -u

indicating that i the resume file is used for hibernation.

So I set its content to

RESUME=none

which made Lubuntu boot quickly. Then I crosschecked with the other installed systems (Xubuntu and Kubuntu) and there is no resume file

/etc/initramfs-tools/conf.d/resume

at all, and the RESUME keyword is not found in

/etc/initramfs-tools/

So I think Lubuntu has a left-over file from when it used a swap partition, and a quick fix is to simply remove it and run

sudo update-initramfs -u

Maybe this is also the permanent fix, when done by the Lubuntu Developer ;-)

(Anyway, the swap file, that is created is smaller than the RAM size, so hibernation will not work well anyway. It is outside the scope of this bug report to investigate the conditions for hibernation.)

-0-

I was confused by the fact that Lubuntu was quick to check the partitions in an SSD with 512 B physical sectors but slow to check in an SSD with 4096 B physical sectors.

Now it is no longer a second or two slower than Kubuntu and Xubuntu to boot in an SSD with 512 B physical sectors.
