When you installed Linux, it should have prompted you to create a swap disk.
Go into Yast | System | Partitioner
If you're lucky, you might already have a partition that can be turned into a swap space.
Otherwise, you might be able to go into [Create] and make a new partition (without destroying any of your original data).
You won't "hurt" anything until you click [Apply]
