<div dir="ltr">I have been running stable. Â After a power outage, my system came up with VCs but no display manager login screen. Â Eventually I found that gdm3 was not installed. Â "sudo apt-get install gdm3" failed because due to a missing dependency. Â I resorted to<div>
  sudo apt-get install -t unstable gdm3</div><div>which succeeded.  However, I could still not login.  I got a completely black screen with no cursor, and a completely dead keyboard (I could not reach a VC or even toggle the caps lock and num lock indicator lights).  </div>
<div><br></div><div>I was able to boot in "recover mode". Â Using a different machine, I looked for some help, eventually found this bug, removed gdm3, installed lightdm instead, and was back in business.
