There is no .bck file. Furthermore, the only file in the /etc/X11
directory with a recent modification date is default-display-manager,
which contains a single line /use/sbin/gdm
The modification date/time is about when the system stopped working.
I have a nasty suspicion, (based partly on Windows experience, hence
probably wrong) that a binary has been replaced with one which doesn't
like the I815 chipset. Is there a straightforward way to undo updates?
I am assuming that I was running Gnome because there was (ans is) a
help icon at the top of the screen with Gnome as a prominent item. I'm
pretty sure I'm running Gnome now. The filer claims to be Nautilus.
This installation is pretty much default. The only major changes have
been setting up Samba and NFS.

The trouble is I suspect the ones important to me at the moment are
X11 (in /etc/X11?) Samba (where?) and NFS (/etc/mount and so on). Not
all in my home directory.
