Comment 2 for bug 1406970

With continuing attention to this bug I discovered that I could select Lubuntu at login and that this got me to a proper Desktop with full access to the OS's procedures, accessories and applications, including the other primary partitions on the hard drive and to my LAN.

See Question 259840, which I marked as solved.

The bug reported here did not repeat on several restarts, although attempts to start Ubuntu, Gnome-Classic, and Gnome via this same route (a long list of alternatives being presented at login) all produced crashes or negative outcomes. As always, I could get to the Terminal in nearly all cases with contr+alt+F*.

Hence, the bug reported here shows tons of information about my installation history, which may yet prove quite useful, this bug isn't bugging me any more ... the dskyop PC is now useful again.
