Add swap file to Xubuntu system missing swap partition?

Asked by Harold Heinbaugh

I manually partitioned my Xubuntu desktop and did a clean install without a swap partition. Do I have to blank the drive and redo the partitions and reinstall OS? Or, is there a way to reduce the size of the large partition and add a Swap partition? gparted will not allow me to shrink the large ext4 partition eventhoughugh the size/move screen appears the attempt to reduce the size does not respond.

At first: on most systems today with 4GB RAM and more there is no need for a swap partition. Except, of cause, you are doign very RAM intensive things.

Also there is the option to create a swap file instead of a partition.

You must boot from a live media of Ubuntu (Xubuntu) such as CD/DVD/USB and then use gparted from there. The root partition must be unmounted so gparted can shrink it.

Swap file is a good choice ,although is bit slower than the partition.

Swap memory is needed if you want to hibernate.
