This issue was resolved by the yesterday updates. Today I launched the computer and I could login to normal gnome-session without any problem.
The related update packages could be gdm_2.96.6-0ubuntu4_i386.deb gnome-session_2.29.6-0ubuntu4_all.deb gnome-session-bin_2.29.6-0ubuntu4_all.deb gtk2-engines-pixbuf_2.19.6-1ubuntu3_i386.deb No X-related packages were received yesterday, so, very likely the issue was within any of the above packages. -- GDM login fails with regular gnome-session (lucid, i386) https://bugs.launchpad.net/bugs/526379 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
