That's perfect. A disk (due to rules dating back to at least the XT and
DOS) can only have 4 _Primary_ partitions. When it was discovered that
perhaps 4 wasn't enough (approximately the same time we found 640K wouldn't
do for memory). So they created "Extended" partitions that can contain
other "Logical" partitions. Your setup has 3 Primaries, 1 Extended, and
then 1 Logical inside the Extended.
So then you should be able to simply change the lines in /etc/fstab:
UUID=52810d5c-61ab-4942-afa2-9e6e953f839d none swap sw 0 0
/dev/sda5 none swap sw 0 0
(use sudo to edit it if you want to use a non-GUI editor like nano, or
kdesudo to edit it in a gui like kate)
Finally, "sudo swapon -a" should turn on your swap.

Ah! I suppose that's one of the hazards of your job.
