+As I realized after a while that my setup didn't make use of the 5G big swap partition at /dev/mapper/ubuntu--vg-swap_1 but used a rather smaller swap (< 1G!) I had to do some research again. I had to
+</markdown><cli>
+sudo swapoff /dev/mapper/ubuntu--vg-swap_1
+sudo mkswap /dev/mapper/ubuntu--vg-swap_1 $((1024*5000))
+sudo swapon /dev/mapper/ubuntu--vg-swap_1
+</cli><markdown>
+and `htop` as like as `swapon -s` showed me that now the far bigger 5G partition was used as swap.
+To get that persistent even after an update of the kernel I had also to
+</markdown><cli>
+lsblk -o NAME,UUID ## to get the correct UUID of the swap partition
+sudo <your editor> /etc/initramfs-tools/conf.d/resume # to exchange an old UUID that prevented initramfs from working properly to the new one
+sudo update-initramfs -k all -u # to update all the kernel variants that could be booted from grub
+sudo update-grup ## to update grub :-)
+</cli><markdown>
+And important thread that helped was https://www.linuxquestions.org/questions/ubuntu-63/ubuntu-19-04-19-10-problem-with-encrypted-swap-partition-4175673274/.
