Don't know why you want to get into single user mode.... you might mention
that.

I just did the following:

booted
got the GRUB menu
did a normal boot
got to the KDM login screen
did a CTL-ALT-F2 (I think I told you CTL-F2)
got console login prompt
logged in as normal user
did: sudo telinit 1

As far as I could tell (there must be a way) I was at runlevel 1. KDM
was no
longer running which is a good indication. Lots of msgs on the screen
as to

things being shutdown, etc.

Should work.

---------------
Not a hope I'm afraid on my machine - stand by for a long transmission:

KDE multi-user running AOK
cntrl-Alt-F2 OK
login as root OK
telinit 1
|
blue booting up screen with 5 'rotating' dots
|
hit esc. BEFORE rotating dots stop (when dots stop- no mouse, no
keyboard - stalled)

|
'could not write bytes - broken pipe...status 255'
|
recovery menu
resume -> recovery menu(resume)
clean -> recovery menu(resume)
dpkg -> recovery menu(resume) - had installation CD in drive,
just gave a lot of error messages
failsafex -> final message on screen is 'will now switch to
single user mode'
only way forward from here was to switch
off/on on the wall socket
grub -> said 'generating .cfg file' then -> recovery
menu(resume)
netroot -> gobbledygook - stopped dead, switch off/on on
wall to reboot.
drop to root -> says type root password or cntrl-d to continue,
cntrl-d lead to

switch on wall recovery. root password worked
|
telinit 1
broken pipe and back to recovery menu(resume)
|
drop to root
|
startx
|
nearly worked, but no networking, because root not $user
|

gave up!!

Hope the above makes sense.
The reason I wanted to go into single user mode was because I have been
having the odd flaky boot once or twice a week, the symptoms being
very like a hard drive with a dodgy block in the boot area and I wanted
to do an fsck with various flags to see if anything came up.
I was bone idle when I installed Lucid and just had the one giant
partition

shan't do that with Maverick.
I've got 'https://help.ubuntu.com/community/KeyboardShortcuts' but it
doesn't mention the CNTRL-ALT-Fx functions at all, do you know where I can
find them please.
Thank you very much for your help and advice but don't spend a lot of
time
on this as I'm going install Maverick shortly - maybe that will make a
difference.

regards
brian

The CTL-ALT-Fx function has been there pretty much since day-one of the X
server.....

F1 thru F6 will take you out of the X environment and put you at a real
console login (or session if you've been there before)

Once you are at the console level, ALT-Fx (1 thru 6) will move you from one
console session to another. ALT-F7 will take you back to the X session.

Not sure about the ALT-F8 session, but sometimes it shows the boot messages.
