I have been running this PC on Ubuntu 10.10 and it has been pretty great. With the HDD filling up and persistent messages about my version of Ubuntu not being supported I started again on 12.04. I am not really feeling the love with this version. Personally I despise the desktop with the icons down the left hand side so the first thing I do is install the classic version. Now I am not sure if this is the problem but the performance is pretty underwhelming compared to 10.10 and I will be the first to admit this PC is old (see below). Can someone suggest a build better suited for a more 'senior' computer?

They are plenty distributions adapted for old computers. If you want to stay within the Ubuntu realm, I recommend Lubuntu, which I really like. The main difference being that you would replace Unity by LXDE (as well as standard applications by lightweight ones, but you can always re-install the ones you really want since it is still ubuntu), which requires much less memory.
Have fun,

Would this be good for an old netbook, like the Acer Aspire One ZG5? – Robert S. Barnes Apr 5 '13 at 14:29
yes. the requirements for lubuntu are the following: Lubuntu can be installed on a Pentium II or Celeron system with 128 MB of RAM, but such a system would not perform well enough for daily use. With 256MB - 384MB of RAM, the performance will be better and the system will be more usable. With 512MB of RAM, you don't need to worry much. The default "Desktop" installer requires 384-800 MB of RAM (depending on selected options.) If you have problems, please use the "Alternate" installer. – Victor Apr 5 '13 at 14:32
Is there a way to get a 10.04 Netbook Remix style interface? This netbook has a 9 inch screen. – Robert S. Barnes Apr 5 '13 at 15:10

Currently, I am using Ubuntu 12.04 LTS on an old Sony TX3XP laptop:

  • Celeron 1Ghz
  • 1.5 GB memory
  • 80 GB 5400rpm hard drive

It is working well. I tried 12.10 on this laptop, it was not powerful enough. But 12.04 is just fine.

What to do:

  • Install the nvidia restricted driver, and then, be sure to run the default Ubuntu session with desktop effects managed by the GPU (Ubuntu, not Ubuntu 2D)
  • In you Home directory, press ctrl+h to display hidden files and remove any file related to Compiz (.Compiz, Compiz-1, etc.) You will find files and directories in /home/username and /home/username/config. This way, Compiz will create again default setup of 12.04, wich are not the same than for the previous versions.
  • If you think that some other applications need a refresh, do the same with other configuration files and directories, just take care to save data if necessary.

This kind of cleanup should make your old computer more "fresh"
