LightDM launching new Xorg process (in a new VT) after every resume from suspend

[Ryan]

It appears that whenever a suspend/resume cycle occurs (close/open lid on laptop), LightDM launches a new Xorg process in a new VT before re-activating the original process on VT7. This causes a noticeable delay in being able to login with the greeter and causes the screen brightness to change before going back to what it should be set at.

LightDM version - 1.18.2-2

Attached is the lightdm log, and here is the output of ps showing the different processes.

Let me know if there is any info or logs that are required to investigate this issue.

Here is the output from ps, formatted a little nicer than in the original post.
