This file doesn't appear to exist, but  think SuSE moved a lot of stuff
from init.d

Anyone any idea where I can find it? Though it may not be the problem
(see below).

Control-Alt-Backspace has brought back my desktop, but I've still got
problems. The windows I get don't have the various buttons (minimise,
maximise) and I can't move them. I seem to have only one desktop,
although it tells me I have six and I can't create a second session. I
think It crashes as soon as it tries.

I tried to have a look at .Xauthority and also some xsession-errors
files that I found. Unfortunately, I can't find which program to use to
read .Xauthority and I can't make head nor tale of the .xsession-error
file I found.

It reads

/etc/X11/xim: Checking whether an input method should be started.

INPUT_METHOD is not set or empty (no user selected input method).

There is no default input method for the current locale.

Does this make any sense?

I looked at these files and they only informed me that X couldn't find
various font folders which I don't think I have anyway. I could
investigate further if I had some idea of what I was looking for. But
these were the only errors reported.

Does any of this give anyone any more ideas of where I should go?
