Severe KDE Konsole flickering

[diamond]

OS: FreeBSD 7.2, KDE: 3.5.10, driver: xf86-intel-video-2.7.1, graphics adaptor: Intel 865G, motherboard - ASUS P5PE-VM.

Noticed severe flickering while output scrolling in Konsole window. CPU usage is about 100%. As it scrolles, it is impossible to switch a tab, everythings really hungs.

xorg.conf has nothing special in it. DRI, i915dri modules are built into the kernel.

Is there any solution for this thing?
Windows XP/Vista works just fine, no slowdowns.

Thank you.

I don't use Intel not KDE.

But a couple of months ago I experienced similar problems under XFCE4 (unresponsive behavior, very slow, 100% CPU usage, etc). Turned out to be related to hal, dbus and xorg settings.

Make sure you've built x11-servers/xorg-server with hal (default option), enable hal and dbus on /etc/rc.conf.

Have a look at http://www.freebsd.org/doc/en/books/handbook/x-config.html for the exact steps explained with finner detail.

Also it would help if you've posted your /etc/X11/xorg.conf and /var/log/Xorg.0.log.

I have everything enabled: DBUS and HAL.

xorg.0.log has nither errors nor anything special and is rather big, so I will omit it.

[tangram]

Run cat /var/log/Xorg.0.log | grep EE and cat /var/log/Xorg.0.log | grep WW.

Post the results as these might help spotting problems.

[morbit]

cat /foo/bar | grep foo is stupid.

Use grep foo /foo/bar.
