Good day, Carlos, and Packmans!Carlos, you told me something I didn't know! There was no hibernate option available for my Tumbleweed machine. Upon investigation, it turned out that the problem was that I had never created a swap partition. I installed both machines several years ago. At the time, I just accepted the default options for the partition table suggested by the OpenSUSE live stick installer. The only exception was that I created a 30 GB partition for /var/cache, because one of my friends had told me that OpenSUSE requires a large cache partition, the default option is not good enough.
Hum! It doesn't create a separate partition, it is all in the common root — which is necessary if you go with the default of using btrfs for having snapshots, which is a good feature.
But the installer doesn't create a swap partition by default.
Not always, true. It may ask if you want hibernation, there is a tick somewhere, and then one is created. There are many subtle options or choices that have consequences :-)
I didn't want to resize any of my existing partitions on my boot drive, because I heard that was dangerous. But, I thought there would be no harm in deleting my cache partition and creating a new one, after using some of that space for swap. 30 GB is probably a bit big for a cache anyway.
If your root is big, you do not need a cache at all :-)
So, this was my procedure. I had already created a Leap 15.4 live stick last week. I used that to boot Tumbleweed from my root partition. I saw that when you do that, the whole /var partition is mounted on the live stick. So, I deleted the /var/cache partition on my boot drive, created an 8 GB swap partition - that machine has 8 GB of RAM, and a smaller 22 GB cache partition. I used the YaST Partitioner to do that.
(depending on your usage, you may need more than 8 gig of swap later)
(As an added bonus, I also saw that I had an unused and unmounted 40 GB partition!) I shut down and rebooted from my boot drive, and then, as if by magic, the KDE Power / Session menu suddenly contained Sleep and Hibernate options. I tested the Hibernate option, and it works perfectly!
Nice :-)
I am going to do the same to the Leap machine today. Thank you very much, Carlos, this is going to save me a lot of pain, for more reasons than just doing builds! What I was previously doing was shutting down two machines every time we were scheduled for a power cut, and then restarting them both when the power cane back on. Now I can just hibernate them both!
Normally packman list is not used for this kind of help, but I figured you were doing that, and that hibernate could help :-)
