If I add memory, do I need to enlarge the swap partition?

[Robert.Thompson]

Hello:

I bought 2 gigs of ram to add to the existing 4 gigs - do I need to increase the size of the swap partition?

If so, can this be done without harming my root and home partitions?

If so, how?

Thanks,

im pretty sure you could make your swap partition smaller, however i would just leave it as is

No....in fact in some instances you can actually remove the swap partition. The swap partition is virtual memory. The more physical memory you add the less work your disk has to do.

dependss on if you hibernate your computer.

If you use the Hibernate feature, your swap must exceed your RAM. Otherwise, you may not even need swap at all, depending on your typical RAM usage.

No.

Echoing the above posts.

If you plan to use Hibernate, then yes, you should increase Swap.
If you don't, then you do not need to do anything to it.

To increase it, you'll have to boot from a Live CD and use Gparted to shrink your Ubuntu Partition and enlarge Swap.

Make an informed decision based on your particular needs.

Thanks to all of you!

Just curious, is there a limit as to how much memory Ubuntu can use or needs?

Ubuntu can probably use any realistic amount of memory on 64-bit or 32-bit with PAE. As for minimum requirements.. 512 is a solid number but you can get away with less, especially if you use xfce/lxde.
