There is no crash report generated in /var/crash. The X.org.0.log of the crashed X ends with: Backtrace: 0: /usr/bin/X(xf86SigHandler+0x6a) [0x48402a] 1: /lib/libc.so.6 [0x7f428f840100] 2: /usr/lib/xorg/modules//libwfb.so(wfbRasterizeTrapezoid+0x18b) [0x7f428cac86cb] 3: /usr/lib/xorg/modules/drivers//nvidia_drv.so(_nv000745X+0x12f) [0x7f428d2cf38f] Fatal server error: Caught signal 11.
