Xorg.0.log

My X-server always halts spying out backtraces whenever I configure my screen
with xrandr. One of them looks like the following:

view the debuginfo like the following:
less -r backtraces

note: the libc-debuginfo decodation may not match exactly since the version of
the library and the version of its debuginfo do not match.
