Further digging has shown up a possible culprit. I'm using the nVidia supplied binary drivers for XFree86 (i.e., not the drivers shipped by xfree86.org). The drivers were installed *after* KDE, and supply their own GLX libraries. If I remove KDE, install the drivers, and then reinstall KDE (from source) so that KDE links against the nVidia supplied drivers instead of the XFree86 libs, the system becomes much more stable. I've only been running with this for a few hours, so it's too early to tell if this is a complete fix or not.

Please note that we have already determined that there is some
sort of conflict between XFree86's Mesa and the nvidia drivers.
The reason it manifests itself in KDE is due to the fact that Qt
installs with OpenGL support by default.
So if you are still up for debugging, that should provide some
hints as to where to look. Most KDE/nvidia users I've seen
prefer to rebuild qt without GL support (as it is not needed for
the majority of qt-based apps including KDE).
It may be a bug in Qt or KDE.. I haven't seen definitive evidence
to that end.

State Changed From-To: open->closed Fixed by building the beta KDE 3.1.1 port with WITHOUT_OPENGL=yes in /etc/make.conf. For the record, this involves removing KDE *and* the QT libraries, and then reinstalling. |
KDE starts fine with an 'exec startkde' line in ~/.xinitrc file. However, quitting any program ("File -> Exit", clicking the close button in the title bar, etc) causes it to crash, bringing up the KDE Crash Handler. The app (Konq, kghostview, ark, ...) "crashed and caused the signal 11 (SIGSEGV)" according to the crash handler. Because KDE was built without -g, the backtrace is empty. Fix: Unknown. How-To-Repeat: Start a KDE app, close it.
