Subject: Re: ports/145649: x11/xorg: X server crashes when starting opengl
compositing manager

I have precisely the same problem with Intel integrated graphics (on a desktop)
and KDE4. X crashes as soon as OpenGL desktop effects are enabled. This also
happens on the initial KDE4 start when DRI is enabled in xorg.conf, apparently
KDE auto-detects OpenGL capability and tries to enable the effects.
Here's a backtrace with debug symbols enabled in i915_dri.so:

I see that intelObj->mt is NULL and the crash happens on dereferencing it.
