[SOLVED] Gnome3 crash between gdm and gnome-shell

[pjv]

I'm in the middle of doing a big upgrade on my system. Almost all packages are updated, so it's time to try gnome 3.2.

When I boot the laptop into gdm, and login as my user, gdm switches out, seemingly to start gnome, but then returns. I never see gnome.
If I login as root, gnome does start up nicely.

I then stop xdm from a terminal and login as my user, and do "startx", and gnome works nicely.

Problem is I can't figure out why gnome bails out in the typical usecase. There's still lots of other problems and stray error messages, but gnome works ok.

.xsession coming up....

.xsession-errors (doesn't differ between sessions):

The greeter.log sometimes contains:

The slave.log:

gdm-simple-slave[28314]: WARNING: Child process 28343 was already dead.

Are any other debugging techniques available to me?

I solved it. Had an improper PATH in one of my shell scripts. See the comment at http://www.held.org.il/blog/2011/02/sol ... n-problem/
