Can you disable xdm, run the failing server and capture stdout and stderr. The fact that the backtrace goes through dl_* stuff seem to indicate a failure while loading a shared object. ld.so writes its errors to stderr and this doesn't get captured in Xorg.0.log There may be something intesting to read here. Otherwise build the xf86-video-nv with debugging symbols too and get a backtrace, if possible by running Xorg directly under gdb, rather than from a core file. From a remote login run sudo gdb Xorg and then 'r' ... -- Matthieu Herrb
