I installed xserver-xorg-core-dbg and tried attaching to the running X
server using gdb, but that didn't generate any useful info:

$ cat ~root/gdb.txt 
Attaching to program: /usr/bin/X, process 3473
(no debugging symbols found)
(no debugging symbols found)
0xffffe410 in __kernel_vsyscall ()
Continuing.
Warning:
Cannot insert breakpoint -3.
Error accessing memory address 0xd0f0: Input/output error.

Detaching from program: /usr/bin/X, process 3473

/usr/share/doc/xserver-xorg-core-dbg was silent on how to do a proper
debug session.  Any pointers?
