With composting disabled, I find that KDE 4 runs faster on the same
hardware than KDE 3 did. I have installed Kubuntu 9.04 on some rather
old machines (up to the earliest Pentium 4's) without problems, so
long as the machine has 512 MB RAM, both on ATI and Nvidia graphics.
Please start a new thread on that issue, so that others will take
notice and help, because from my experience KDE 4 non-composting runs
fine on older hardware. If not, then bugs should be filed where
