Why can't I enable swap on startup?
I made I swap partition with GParted and it works great, since my computer only has 2 GB of memory. But, every time I boot up, I have to execute sudo swapon /dev/sda1 until it enables. How can I set it up so it enables automatically. I am have only been using Ubuntu for three months, so you might have to spell things out for me.
Solution 1:
Swap partitions are enabled either:
- on boot if they're listed in
/etc/fstab
- when you run
swapon /dev/<device>
- or when you run
swapon -a
, given that you have some swap devices configured in fstab.
Run:
grep swap /etc/fstab
If there's no output, you don't have a swap partition added to /etc/fstab.
If your swap partition is i.e. /dev/sda1 add
/dev/sda1 none swap sw 0 0
to the end of your /etc/fstab
file and run swapon -a
.
Verify that your partition is in use as a swap via
cat /proc/swaps
