I was testing on os201; I haven't updated the XO yet. This may be the cause of
the difference.

The color choice dialog doesn't load very much of the sugar codebase.

The "doesn't proceed beyond" behavior strongly suggests that an exception is
being thrown.

You couldn't find logs of the failure because olpc-dm is redirecting stdout and
stderr to /dev/null.

Fortunately, olpc-utils rebuilds easily on the XO as soon as its builddep,
ConsoleKit-devel, is installed.

   (Just run "make -f Makefile.build; make -f Makefile.build install".)

Then you can redirect the stdout/stderr output to the log file of your choice
or, as I do, you can run /etc/X11/prefdm manually.

   (To enable this, I usually tell /etc/event.d/prefdm to run /bin/true and to
   not restart, thereby dropping me off at the virtual terminals on each

Also, alternately, you can install Xephyr and use it from Gnome or raw
X+metacity to find out what's going on.

Entirely possible.

Thanks for the report; I'll see if I can produce the same behavior.
