Add no display manager support

[RaafatTurki]

Some folks (me included) don't use display managers like lightdm or gdm
I personally just execute good old xinit right after login (using .profile), other people use ly or tbsm

Point is not all use a graphical display manager.
I ended up editing stop_display_manager to

function stop_display_manager {
  pkill xinit
  while pgrep xinit > /dev/null; do
    sleep 1
  done
}

Which works fine (keep in mind this is x11, wayland people should do something else) however I couldn't get restore_display_manager to work
Simply executing xinit doesn't do anything, I believe because it's not executed in a tty

The end result is whenever I shutdown my vm, I face a really scaled down version of my tty to the point all text becomes blurred

I can execute xinit or startx - and get back to my window manager just fine (even the tty restores its original resolution) but I'd rather my window manager be automatically launched

I will test with ttyecho and see what I can do

ttyecho worked, I've installed it via the aur and edited restore_display_manager to

function restore_display_manager {
  ttyecho -n /dev/tty1 xinit
}

it opens my windows manager on tty7 instead of tty1 (where it originally was) but I'm nitpicking at this point
