I rarely reboot. Tonight I had some updates that failed (one that I remember was python). I figured it was odd, so I would reboot and try updating again. Only now I get stuck on

```
[ OK ] Started GNOME Display Manager. Dispatcher Service......tem changes.pp link was shut down...."

```

I believe I have kernel 4.15.0.24; I was able to reboot to grub once and try 4.15.0.23, but it ended up in the same spot.

I also tried CTRL+ALT+F2 but keyboard gos unresponsive at that point. My system is a System76 Sable Touch 3. 4th Generation Intel® Core™ i5-4440S ( 2.80GHz - 6MB cache - 4 Cores - HD Graphics 4600 ), so I am not certain it would be the same issue as those with the nvidia cards.

I am uncertain how to proceed in troubleshooting and hopefully, back up and running.

I was able to eventually get in by `CTRL`+`ALT`+`F3` log in and install `lightdm`. 
Obviously it is just a temp workaround, but there are still more issues. 

I get many `python3` & `dkpkg` errors when `sudo apt update && sudo apt upgrade`. 
also:
