I spent a bit of time over the weekend trying to isolate the problem, but with no success. One thing I did notice though is that the game Einstein (http://games.flowix.com/en/index.html, it's also available in the Ubuntu repositories), maxes out one of my CPUs from the moment that it is launched, even when it is only on the Start screen. I first noticed this because it was taking a long time for the Window to close when I finished playing and so had a look. I then tried the same process on my wife's machine, and found that it does not exhibit the same problem. Mine is a home-brewed desktop with a dual core 64 bit Athlon running a fully patched Kubuntu 9.04 and the KDE 4.3 patches (available at http://ppa.launchpad.net/kubuntu-ppa/backports/ubuntu). My wife's machine is a fully patched Mesh desktop with a dual core 64 bit Athlon running Kubuntu 9.04 and without the KDE 4.3 patches. It looks likely therefore (but not certain), that the KDE 4.3 upgrade is the problem. When I installed it, I was aware that there were risks in doing so, and was quite prepared to trash everything and start again with a clean install of Jaunty. However, it worked fine for several weeks before this occurred and so I would like to consider all the strategies available before I do anything that drastic. Does anyone have any suggestions as to the best way forward? Can I roll back to standard Jaunty easily? -- Terry Coles 64 bit computing with Kubuntu Linux -- Next meeting: Dorchester, Tuesday 2009-09-01 20:00 Dorset LUG: http://dorset.lug.org.uk/ Chat: http://www.mibbit.com/?server=irc.blitzed.org&channel=%23dorset List info: https://mailman.lug.org.uk/mailman/listinfo/dorset
