This question already has an answer here:

I have some slight glitches running Ubuntu 13.04 in my old beloved Dell Mini 10v. How can I optimize the graphics for it?

It has got 1Gb of RAM and an N270 Atom processor. Very minimal graphics too.

Download and install Unity Tweak Tool from the Ubuntu Software Center and change the launcher and the search configs.

I run Ubuntu 13.04 on a netbook too and this is what I do to optimize the machine:

  1. Install PCMan File Manager (or PCManFM) to replace Nautilus as the default File Manager.
  2. Install Synapse to replace Unity's application laucher.
  3. Remove unused apps and packages.
  4. Optional: install Xfce 4 to replace Unity.

  • @sarat my experience is that you install Unity first to get the assets, and then install other desktop managers. – Hoang Huynh Sep 13 '13 at 10:39

OS use SWAP memory, which is located in HDD. HDD is slower than RAM, reducing the percentage of SWAP memory in HDD will increase the speed.

Check your percentage of SWAP memory using this command:

cat /proc/sys/vm/swappiness

Result will be 0 to 100. To change the swappiness type this command:

sudo nano /etc/sysctl.conf

Add or change the line with minimum value (0 to 10)

vm.swappiness=10

Restart your Notebook and enjoy :)

  • please explain why changing swappiness will help with graphics. – amc Jul 26 '13 at 6:28
