I now know what is happening. I had a large build system that failed if /bin/sh pointed to dash so I set it to point to /bin/bash instead. That is what makes the login fail. starting xinit then "/etc/gdm/Xsession gnome-session" produces the following error
/etc/gdm/Xsession: Beginning session setup... /etc/bash_completion.d/apport_completion: line 128: `_apport-bug': not a valid identifier setting back the /bin/sh link to dash makes it work and I can also login from the normal gdm login screen. So this bug should be moved to apport or maybe bash ?? but I do not know how to do that -- gdm can't login to any session https://bugs.launchpad.net/bugs/596149 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
