[PresuntoRJ <fabio.tleitao@xxxxxxxxx>]

can I do it via byobu on the local system (so I can reatach the screen in
case of crash) or should I do it via ssh from a different machine?

I really do not know how long it  would take to actually hit gold here, so
think I cannot keep using two systems at once for several days... any
ideas?

every time I enter gdb and try to attach the runnig Xorg pid, it freezes...
if I try to run if with the -keeptty -dumbSched options, it tells me Xorg is
already running (of course)... if I kill it, it simply respawns... the guide
seems pretty useless cause if you follow the steps there, you cannot get any
backtrace whatsoever. How can I ever get X to run inside gdb?  (I know I
could sudo /etc/init.d/gdm stop, but the only time it is mentioned there, is
totally unrelated with the steps to get the backtrace)

that said, I did manage to start inside gdb and pretty much as soon as I
have loged in, it halted with a SIGUSR1  adn wont resume no matter what I
try... I am not sure what I am doing wrong or if that could be related with
the issue:

(gdb) run -keeptty -dumbSched
Starting program: /usr/bin/Xorg -keeptty -dumbSched
