I think I got this bug. I don't know what exactly causes this problem though... Using iMac Mid2010, rEFIt 0.14, & ubuntu-11.04-alternative-amd64.
Here's my ~/.xsession-errors: ~/.xsession-errors /etc/gdm/Xsession: Beginning session setup... /etc/gdm/Xsession: 301: ls: not found /etc/gdm/Xsession: ssh-agent not found! /etc/gdm/Xsession: Setup done, will execute: gnome-session --session=ubuntu exec: 1: gnome-session: not found -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/654578 Title: Returned to gdm screen after logging in -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
