+ o How to build something with debug information?
+   ----------------------------------------------
+ 
+ You can use "env CFLAGS=-g make -f Makefile.bsd-wrapper build" to
+ build any module with debugging information, but you'll need to remove
+ XOBJDIR/xorg-config.cache.${MACHINE} before doing that because
+ autoconf caches the value of CFLAGS in its cache.
+ 
+ o How to get a core file out of the X server?
+   -------------------------------------------
+ 
+ Several things are needed:
+ 
+ 1) set kern.nosuidcoredump=2 in /etc/sysctl.conf
+ 2) put 
+ 
+         Option  "NoTrapSignals" "true"
+ 
+    in the "ServerFlags" section of /etc/X11/xorg.conf. If such a section 
+    doesn't exist, it can be added as follow:
+ 
+    Section "ServerFlags"
+         Option  "NoTrapSignals" "true"
+    EndSection
+ 
+    anywhere in the configuration file. 
+ 
+ 3) start the X server as root, with the -keepPriv option. A regular
+    user is not allowed to use this option. If you use xdm, you can add
+    the option in /etc/X11/xdm/Xservers. If you want to use startx, you
+    need to run it as root, like this:
+ 
+    startx -- /usr/X11R6/bin/X -keepPriv
+ 
+ Now the X server will dump core when catching a fatal signal. But it
+ will also not be able to restore the text mode on exit. So be prepared
+ to log in remotely (serial terminal or ssh) to reboot your machine or
+ to restart X.
+ 
+ The core dump will be in /var/crash.
+
