</I>&gt;&gt;<i> look to be going well up to that stage, then I see messages like

</I>&gt;&gt;<i> .... (other similar pairs of lines) Dependency failed for Remote
</I>&gt;&gt;<i> File Systems
</I>&gt;&gt;<i> 
</I>&gt;&gt;<i> After these lines, suddenly two of the QNAS mounts (one of which 
</I>&gt;&gt;<i> is /mnt/QNAS/Lydgate-Data mentioned above) do succeed.  The two 
</I>&gt;&gt;<i> borg2 mounts still fail, as do some of the other QNAS mounts.
</I>&gt;&gt;<i> 
</I>&gt;&gt;<i> A few more lines, and all looks reasonable, until
</I>&gt;&gt;<i> 
</I>&gt;&gt;<i> [FAILED] Failed to start Wait for Plymouth Boot Screen to Quit
</I>&gt;&gt;<i> 
</I>&gt;&gt;<i> then Reached target Multi-User Reached target Graphical
</I>&gt;&gt;<i> Interface
</I>&gt;&gt;<i> 
</I>&gt;&gt;<i> and there it freezes.
</I>&gt;&gt;<i> 
</I>&gt;&gt;<i> Later:
</I>&gt;&gt;<i> 
</I>&gt;&gt;<i> I tried booting from the older kernel.  On the graphical screen, 
</I>&gt;&gt;<i> it appears to get a lot further, 5 bubbles instead of 2, but when
</I>&gt;&gt;<i> I tried it again watching the messages it appears to follow the
</I>&gt;&gt;<i> same path as the new kernel boot, ending at the same place.
</I>&gt;&gt;<i> 
</I>&gt;&gt;<i> Interestingly, though, the nfs mount that succeeds, after saying 
</I>&gt;&gt;<i> it had failed, was not the same one as yesterdays.  Still, that's
</I>&gt;&gt;<i>  probably a side-issue.
</I>&gt;&gt;<i> 
</I>&gt;&gt;<i> The situation now is that I appear to have a completely unusable 
</I>&gt;&gt;<i> M3. The line
</I>&gt;&gt;<i> 
</I>&gt;&gt;<i> [DEPEND] Dependency failed for Remote File Systems
</I>&gt;&gt;<i> 
</I>&gt;&gt;<i> is obviously important.  Not knowing what that dependency is, I 
</I>&gt;&gt;<i> don't know whether it could do more damage than failing to mount 
</I>&gt;&gt;<i> remote systems.  It doesn't sound likely, but....
</I>&gt;<i> 
</I>&gt;<i> If the remote mounts are not critical, just add nofail to the
</I>&gt;<i> fstab options.
</I>&gt;<i> 
</I>&gt;<i> I suspect strongly that any issues with these mounts is entirely 
</I>&gt;<i> separate to the actual graphical boot.
</I>&gt;<i> 
</I>Agreed.  Adding nofail makes no difference.  I've also tried removing
all options, down to a minimum defaults.  However, they shouldn't stop
boot.  FWIW, I'm still seeing that message about a dependency failure
for remote file systems.

&gt;<i> Personally, I was seeing crashes with qt4... perhaps try switching 
</I>&gt;<i> to gdm as you're DM and see if the graphical boot comes up OK,
</I>&gt;<i> that way we could see easily if it's something high level.
</I>&gt;<i> 
</I>No, gdm doesn't get that far either.

&gt;<i> Also you could try and look and see what systemctl status 
</I>&gt;<i> prefdm.service says to you (you might need to switch to tty2).
</I>&gt;<i> 
</I>prefdm.service - Display Manager
  Loaded: loaded (/usr/lib/systemd/system/prefdm.service: static)
  Active: inactive (dead)
  CGroup: name=systemd:system/prefdm.service

(This from looking over my shoulder, so ignore any typos)

I'll worry about the mounts later - the first thing is to get the
system back :-)
