My issue is a bit strange. I am running Debian GNU/Linux Testing Buster, and I'm very happy with it. However, it has one minor but persistent issue that I can't seem to figure out. Each and every time I boot up, I see the start-up messages like normal, the console text. However, when my display manager starts (LightDM), it shows me the mouse cursor, but with a black screen behind it. It's like this every time I boot it up. I can move the cursor around freely at this point.

The fix for this is simple. I press Ctrl + Alt + F1 to open the shell. I see my Bash prompt like normal. I run a couple commands.

$ ps -aux | grep "Xorg"
root      1177  0.6  1.5 439368 60396 tty7     Ssl+ Oct17  40:14 /usr/lib/xorg/Xorg :0 -seat seat0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch
babkock  14990  0.0  0.0   4756   864 tty1     S+   20:10   0:00 grep Xorg

I can see the X window system has been started by root, with process ID 1177. At this point I type this.

$ sudo kill 1177

This kills X. So X restarts, and it loads up LightDM like normal. It shows up perfect, just the way I configured it, everything's responsive and sturdy. I am now free to use my laptop and do what I need to do. I have (almost) no recurring glitches or freezes aside from this.

EDIT: I've been asked for the output of pstree. This outputs something like this:

systemd --|
          # other processes here...
          |-lightdm-+-Xorg---3*[{Xorg}]
          |         |-lightdm-+-lightdm-gtk-gre---3*[{lightdm-gtk-gre}]
          |         |         `-2*[{lightdm}]
          |         |-lightdm
          |         `-2*[{lightdm}]

Is there some way to remedy this? Is there a startup command or script somewhere I can edit? I don't understand why this is happening, and I'd like to fix it because it's rather annoying.
