So I've read several related threads and there seems to be no answer.

I have an old laptop, with a Dual Core 1.7 GHz processor and added 2 GB of RAM, with a 30 GB partition for Ubuntu 12.04 and the remaining for Windows XP.

I want to change the default swappiness from 60 to 0.

When I start the computer and run cat /proc/sys/vm/swappiness in Terminal I get the value 60.

I have no problems changing it to 0 with sudo sysctl vm.swappines=0

I have tried several times changing the file /etc/sysctl by adding at the end

#

# vm.swappiness=0

But every time I restart my computer the value given by cat /proc/sys/vm/swappiness is still 60.

Any ideas as to how to fix this?

Thanks
