Any file which is saved under a dual boot system.  However as I replaced
ubuntu 18.04 with lubntu 18.04 which is working fine, I am trying to use
a netbook to investigate this issue further.

I have a PC dualbooting with Linux mint 18.3 and Lubuntu, I replaced
Ubuntu 18.04 which wasn't working with Lubuntu which does work.

I then decided to install Ubuntu 18.04 on to a netbook,  this still
stops part way through booting (in the same place).  However it does
mean I can work on this problem on a netbook. and still use my main
system to ask for help.

I switch on,  press esc to get text output and it stops after
[ ok ] started user manager for uid 120

this is a block of messages starting with
gdm.servicegdm.service

there is no indication that any of the services within this have failed
(all have [ ok ]

At this point,  the system just ctrl-alt-f1 (and no response from alt-f1
etc either)

However

alt-sysrq RSEIUB work,  so that does suggest that the kernel (and other
processes) are still running in the background and listening for those
key presses,

I also get a mouse pointer up (so it is probably a good 95+ percent in
to getting a gui displayed) not that the mouse pointer moves with the
trackpad.

The netbook has an ip address, so I tried to ssh in, but this failed
with connection refused, as I guess ssh-server isn't running, which was
worth a try.

I can get in to recovery mode fine so am in that now,  so will try doing
the update.

thanks

Paul
