It seems like your "trackerd" is eating up your CPU. Try to "apt-get remove tracker" and restart to see if it will be better. My experience told me some users computers are not suitable to install desktop search(sadly including my newest Thinkpad T61p). <div class="gmail_quote">On Dec 14, 2007 8:27 AM, Robert Fitzpatrick <<a href="mailto:lists@webtent.net">lists@webtent.net</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> I've always had cpu usage problems with Linux on this one machine, my workstation. Throughout the day my cpu spikes up and down and, at least once, evolution 2.10 on Ubuntu Fiesty will send my cpu to 100%. If I can't manage to get it shut down prior to locking up my system, I restart X (Ctrl+Alt+Backspace) and login, all is well again...sometimes must reset the computer. I had previously thought that this is due to Evolution and my LDAP lookup, but since disabled all that and now realize that it happens even with Evo closed. It seems to happen when video on the web or Java or opening PDF's. I have upgraded to Gutsy and still have the problem. Some things I might suspect are my Matrox G550 dual monitor video card or maybe some KDE apps that I run like kalarm and karm. These are the only things I can think of that my laptop does not have, which works great with no crashes. My question is how to proceed in troubleshooting this issue? -- Robert -- ubuntu-users mailing list <a href="mailto:ubuntu-users@lists.ubuntu.com">ubuntu-users@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-users" target="_blank"> https://lists.ubuntu.com/mailman/listinfo/ubuntu-users</a> </blockquote></div> -- -- Yueyu Lin
