Participating in bug 
https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1779476 for the last
couple of days.

Clevo barebook W540 pentium 3805U 1.90G  onboard graphics BroadwellGT1 single 
ssd, intel Wless 3160, only hardware hanging off it is a usb wireless mouse.
Had indefinite hang begin with update to Ubuntu-offered *-24 kernel.
A fair amount of keyboarding and mouse wiggling (average 90s) is needed to wake 
the process up again.
Holding the SHIFT key speeds up the boot to an acceptable delay.
Once into Gnome, networking is also fairly retarded (average 45s) and sometimes 
needs UI operation for the Net Manager to do its usual auto connect to its 
secure network.
Installing haveged stopped the hang.  Network also appears to be more 
responsive, but this can
be masked by the flaky operation of our el-cheapo wireless router.  Using a usb 
dongle which emulates etho appears to deliver much more reliable network start. 

Booting into *-23 stopped all symptoms - haveged not needed.
Booting into the dev channel *-26 returned the hang and added a few display 
artefacts to the plymouth/Gnome handover process.  Zero networking delivered in 
Gnome,  not even a UI for Net Manager.

Hanging a portable WD 1TB spinner off the laptop USB3 port returned a
good boot time into Gnome with the *-24 kernel without haveged
installed. Networking was however delayed variously between 60s and at
one boot appeared to need UI input to wake the hardware up to the secure
connection already in the Net Manager's list, even though Net Manager
could immediately see other networks around the place.

Reverting now to *-23 kernel for the week's work. 
Hope these naive reports were in any way useful.

Bug description:
  This was the last OK then my 18.04 hangs after an update this morning.
  07:00 AM CEST

  Last Ok in boot was Started gnome display manager. dispatcher service
  ...... tem changes.pp link was shut down

  Tried install lightdm from command line and the  response was lastest
  already installed.

  Probably it is what is coming after the lastest OK which is to be the
  error. And here I have lots of guesses......

  Any Ideas ? I need to do some work and I may not be waiting long.

  Search and browsed and now close to give up. Yeah it is a Lenovo.

  Guys: turn of auto update it is a machine killer.
