After upgrading a Dell Inspiron 6400 laptop from Ubuntu 9.04 to 9.10 the machine was so slow it was barely usable. top was showing a load average of 7 after opening Firefox or OpenOffice.
Strangely no command was using more than 10% of the CPU, memory consumption seemed pretty normal and there was barely any disk activity. But the system was painfully slow.
After a couple of hours I decided to follow some obscure forum post (link lost, sorry) and I deleted the xorg.conf file and rebooted the machine. After the reboot the machine was as snappy as before the upgrade.
Weird.

And yes, every Ubuntu upgrade breaks at least one major function. But hey... I was never able to upgrade a Windows machine without problems either...
