Hello :)
I've been following this list for several months now to see how KDE4 is
progressing. I have been running and testing trunk for the last few months
and it's great! Every week when I do an 'svn up' I can't wait to see what
I'll get!
This particular thread has been of interest to me lately as I have been
seeing a similar problem on my Kubuntu 8.10 install on my Gen B Macbook, but
I don't yet know if it is related. When sitting idle for only a few
minutes, I hear my fans spin up like turbines. A quick look at the cpu
history shows that it has been pegged at 50% (one full core) and Xorg is the
culprit. Any mouse movement or keyboard input causes the "problem" to
disapper (as I am typing this the cpu usage is <5%).
Based on the recent advice to try different Qt versions, I switched from the
Intrepid repo copy (4.4.3) to qt-copy from the svn repo. No change. I've
tried changing from the intel video driver to i810 - no change. A few weeks
back it was thought that the systray applet was the culprit, so I lived
without that for a while but still had the problem. I've installed - gasp!
- the gnome desktop to see if it truely is a problem with Xorg and the
problem goes away!?
I've been trying to troubleshoot this as much as I can on my own but I'm
stumped. As I said I'm not sure if this is related to plasma but based on
my experiences it seems that it might be.
Any thoughts?
-Edward

Confirmed.<br>
I moved from KDE:Qt to KDE::Qt44 and the problem is gone! Yay!<br>
