May 02 11:33:02 ambrosia systemd-sleep[874]: System resumed.
Now, after I suspend, it looks like the system is suspending. However, when I resume, I am greeted by my UEFI boot screen. I have tried to make sense of it all, but I don't get it.

The BIOS (v210) is the latest BIOS available for the ASUS N750JV and is the same version that I 've been using for the past three years or so.
I checked gparted to confirm that /dev/sda8 is indeed my swap partition (File system: linux-swap) with UUID 092d8b70-b201-4a78-afdd-f605102d56f7 and size: 9.4GiB
RAM: 7.7GiB
Swap: 10.9GiB (swap partition + swap file)
Swap partition: 9.4GiB
The following is what I have done to try to get resume work again:
1.
I reformatted /dev/sda8 (linux-swap).
I edited /etc/fstab to include the new UUID:
Code: Select all
UUID=092d8b70-b201-4a78-afdd-f605102d56f7 none swap sw 0 0
2.
Next, I edited /etc/initramfs-tools/conf.d/resume ('sudo gedit /etc/initramfs-tools/conf.d/resume') and entered the new UUID of my swap partition:
resume=UUID=092d8b70-b201-4a78-afdd-f605102d56f7
Then I updated initramfs:
Code: Select all
sudo update-initramfs -u
Code: Select all
update-initramfs: Generating /boot/initrd.img-5.4.0-72-generic
I: The initramfs will attempt to resume from /dev/sda8
I: (UUID=092d8b70-b201-4a78-afdd-f605102d56f7)
I: Set the RESUME variable to override this.
3.
So, when that did not have any effect, I edited the grub file at /etc/default/grub
Code: Select all
sudo gedit /etc/default/grub
Code: Select all
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=092d8b70-b201-4a78-afdd-f605102d56f7"
Code: Select all
sudo update-grub
Code: Select all

Sourcing file `/etc/default/grub.d/50_linuxmint.cfg'

Adding boot menu entry for EFI firmware configuration
done
That didn't help.
Somewhere else I read that the PARTUUID should be used. I tried that, but - as you may have guessed - that didn't work either.
4.
As a last resort I chose a different kernel at boot. I am currently using 5.4.0-72-generic, so I went back to 5.4.0-71.
That didn't help either.
5.
I deleted /etc/initramfs-tools/conf.d/resume
Didn't help...
I should add that instead of the UUID of the swap partition, I not only tried the PARTUUID, but also the device name
Code: Select all
/dev/sda8
It still looks like the system is suspending, but it does not resume. It stops, but when I touch the space bar (aka 'any key') the system comes alive, but greets me with the UEFI boot screen instead of the resume login screen.
So, until May 2, suspend and resume worked fine. Then 'something' happened, and now the system won't resume anymore. It looks like suspend is actually working fine, but the moment it is supposed to resume, 'something' goes awry.
I hope some of you wonderful people can help. If you need more info, please let me know.
Thanks in advance!
