Enabling Hibernation in Fedora 23
By default, Fedora doesn't enable hibernation (suspend to disk). Basically what you need is a big enough swap partition. Then it has to be added to fstab and Grub. Initramfs also has to support resuming from hibernation. On my laptop (MSI GE60) unfortunately the swap partition was too small. Fedora recommends that a swap partition should be half the size of RAM without hibernation and 1.5 the size of RAM with hibernation with 8 GB - 64 GB of RAM [1] . This laptop has 12 GB of RAM, but only a 6 GB swap partition. The partition has to be extended to 18 GB. There is a 250 GB SSD with 174 GB of space in /home (ext4 on LVM). I had to reduce the home partition to 162 GB to free up space for the swap partition. Of course, I had to free up enough space in the filesystem first. It is better to have a few times more free space than the amount to be reduced. Resizing an LVM/ext4 /home partition I don't recommend doing this, unless you have knowledge about partitions and LVM.
