This was a 09/29 install that had 1 very weird login Bug 863054
After removing and re-installing lightdm (& deleting the root owned xseession-errors can't duplicate so marking invalid

[Lucazade (lucazade)]

the daily image from today have this issue (09/30)

[Doug McMahon (mc3man)]

Will put back to new, what I see atm on 09/25
admin user is no longer get a root owned here
non admin users are
the ubuntu-user on live session is getting a root owned

I may have gotten the root owned as an offshoot of bug linked above, it has yet to re-occur

[Doug McMahon (mc3man)]

As of today my main admin user session is now getting a root owned .xession.errors on every login.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Jean-Baptiste Lallement (jibel)]

I confirm this issue on a fresh installation with daily desktop image (20111003)
I attached the output of "LIBGL_DEBUG=verbose glxinfo"

important bits:

Together with this problem I get bug 851345 which is maybe a symptom of this issue.
