Ubuntu runs at 50-60% CPU


I installed Ubuntu Hardy Heron about six months ago, and it has gradually slowed down, and CPU utilization has crept up to the 50-60% range. The DEV folder contains a large number of similar files - TTY0 through TTYZF or PTYA0 through PTYZF. I suspect that something is not configured right, but, I don't know where to look.

I connect to the internet through a G4 Wireless Transceiver connected to my ethernet port on an IBM Think Center 8187.

It should be pretty easy to tell what's eating at your CPU by looking at 'top'.

Is there any particular reason you're using Hardy Heron which is 3.5 years old? If not, I suggest you upgrade to the latest version (Lucid Lynx).

"TOP" told me that XORG is the culprit - now to track down why. I am running Hardy Heron because I had the CD handy - maybe I'll just download the current version.

You SHOULD/MUST download the latests branches of the distribution (in case of new install).
(for Ubuntu it's either the Koala, or the Lynx currently)
Many reasons to do:
- security
- usability improvements
- hardware support
etc etc

if there is no real reason to stick to an "old" release, never use it.
it gives mostly more headaches (old releases) opposed to pleasure (newer releases)

Hi

I suggest you install the latest version and check if the problem persists. I remember having a similar issue with Hardy but I can't recall what I did to fix it - will edit this post if it comes to me.

Thank you everyone. I have downloaded the current version - 10.04 - and everything runs from CD, so, I will be installing to hard disk. Again, thank you for your help.
