At that point, you look for errors in ~/.xsession-errors or, more usefully,
in the X log file. Which, for stretch-and-later, on most hardware, will
be in ~/.local/share/xorg/. Or if for some reason your X server still runs
as root, it might be in the /var/log/ directory.

Start with the basics. Can X run *at all*?
Make sure xterm is installed, and try
startx xterm
That works ! This is the only graphic thing that I have been able to
launch since the crash
That should give you the barest possible X session. If it works, you'll
have a mostly empty screen, but with an xterm in the upper left corner.
You'll be able to move the mouse pointer around, and if the mouse cursor
is inside the xterm window area, you'll be able to type in the terminal.
Do that, and type "exit" or Ctrl-D in the xterm to get out.
If it DOESN'T work, try to figure out why, by reading the X log file.
