Comment 38 for bug 292791

I can confirm that I have the same "unable to log in" issue with Intrepid 8.10.
First, a little history ...
Several months ago I burned an ISO of Hardy Heron 8.04.
Two weeks ago I finally got around to trying it and decided to install it.
I installed the recommended upgrades and used it for a day or so before I went for the Intrepid Ibex 8.10 Upgrade network install from the Ubuntu web site.
Wanting Flash I plugged it in to FireFox. After a few days, whenever I accessed a site that featured a Flash enabled program, FireFox stopped responding and had to be closed down.
Meanwhile, wanting to set up a two PC router based wired home network I install Samba and promptly entered into configuration Hell, the details of which are posted here:

I eventually got Samba running and had my shares fully accessible to the network. Shortly thereafter I enters a new level of Hell ... Segmentation Faults mostly around Samba.
A little research suggested that Segmentation Faults were probably associated with bad memory or an installation becoming corrupted.
I shut down my PC and started checking my RAM sticks ... I found and replaced/removed two bad ones.
Ever since then, I am unable to log in to Intrepid. Going into the command line via Grub does not work either.

I hauled out my Hardy ISO and reinstalled it on a separate partition and now have a dual boot 8.04/8.10 system, but Intrepid is still inaccessible, however, via Hardy, as expected, I am able to see my Intrepid drive.

Ok ... here is the opportunity. [DISCLAIMER: I am a virtual Linux noobe] I am comfortable with going in and tweaking things and I can work with the Terminal and command lines. Tell me what you need to look at and where I can find it and I will deliver it. I will not attempt to fix my Intrepid until you have all that you need and are able to offer a bugfix.
