Bug Description

hwpack_linaro-omap3_20110124-0_armel_supported.tar.gz
linaro-natty-efl-tar-20110124-0.tar.gz

When booting, I get a popup message on the graphical console after X starts saying "No valid session found."
The "X" mouse curser is present, and the mouse works, but the graphical console switches back and forth between a black screen and a red screen several times
No panic/oops in dmesg,

From /home/linaro/.xsession-errors:
gnome-session[677]: Gtk-CREITICAL: IA__gtk_main_quit: assertion `main_loops != NULL' failed

Bugs also affect Ubuntu.
It's breaking LTSP in Natty.

It seems to be because "/etc/X11/Xsession" without parameters should start the default X session and not fail saying "No valid session found". gnome-session should just start whatever should be the default.

@Stéphane: in fact, it's not really the cause :)
The cause is that it tries to launch /usr/share/gnome-session/session/gnome.session by default, which is correct, but this one try to get acceleration and doesn't fallback because of a key change.

So, what I'll do for now:
- change the default to ubuntu
- fix the gnome.session file to the new syntax

Not sure that the ubuntu session will works for you as it's testing for acceleration, so it will probably fallback

I tried using the gnome3 PPA for a couple of hours and noticed it was causing multiple crashes to the desktop, so I purged the PPA and restored the old versions of the installed packages using synaptic.
For some reason now I keep getting the error message whenever I try using the ubuntu entry in the login window. I can still use the "ubuntu classic" just fine. But I really like the new look and want to get to work again.

Is there anything I need to do or is this a bug?

BTW. I'm using natty beta "2.6.38-8-generic"
