Comment 9 for bug 355721

I disagree. Can´t see since when .xsessionrc is the default sourced file, this would be against a lot of legacy.

Yes it was so if the scripts look the same the issue is elsewhere, that´s exactly the point. Maybe a permission issue. And in the scripts if you read all of them you will find that usexsession and altusersession should be sourced. Maybe these are not being correctly set.
