Method 3 of 3:

Adjusting Linux OS

  1. How to Adjust Virtual Memory Picture 13
    Backup any data that you want to keep-resizing partitions can cause data losss/corruption. Boot from live cd-it needs to have gparted on it. It should detect that you have linux installed and will use the swap space.
  2. How to Adjust Virtual Memory Picture 14
    Open gparted and click on your swap partition (right click) press swap off. This dismounts swap so you can increase the size of it.
  3. How to Adjust Virtual Memory Picture 15
    Shrink a partition next to it by the same size that you want to increase your swap partition by. So let's assume you have 4gb ram and 4gb swap. You need an 8gb swap. So you should reduce the partition next to swap by 4gb. The unallocated (greyed out) space should be next to the partition. (This may be done by booting through CD ROM and un-mounting the partitions). Now click on the partition (the bar at the top of gparted) and select resize. Include your unallocated space. click swapon-restart.
