PETSC debugger

[Ryan Yan]

Dear Berend,
Thanks for your suggestion.  I can see that option right there!!

However, I am still struggling to find a way to turn this option off as I
can see from

vyan2000 at vyan2000-linux:/etc/gdm$ ps -ef | grep /usr/bin/X
root      5287  5285  3 14:19 tty7     00:00:42 /usr/bin/X :0 -br -audit 0
-auth /var/lib/gdm/:0.Xauth -nolisten tcp vt7

I am using Ubuntu *gnome*, but there is no such gdmrc file that I can
correct. I tried several other ways, but have not succeed yet.
vyan2000 at vyan2000-linux:/etc/gdm$ uname -a
Linux vyan2000-linux 2.6.24-24-generic #1 SMP Tue Jul 7 19:46:39 UTC 2009
i686 GNU/Linux

I am still searching....

Regards,

Yan
