I see. All comments. Which is about the same as not having one. Hmm.
Well, going back to an earlier post:

What puzzles me is the message, "waiting for server to shut down". What
caused that error? Did you do a Ctrl+Alt+Backspace to request a shutdown?
Or did it shutdown automatically? If so, what caused the error? Was it
the "/dev/fb0: No such file or directory" error? Or was it SELinux-related?
I've never had any SELinux-related problems on my system. Just for grins,
let's try an /etc/X11/xorg.conf file that looks like this:

-----

Section "Device"
Identifier "Configured Video Device"
Driver "intel"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Device "Configured Video Device"
Monitor "Configured Monitor"
DefaultDepth 16
Subsection "Display"
Depth 16
Modes "1024x768" "800x600" "640x480"
EndSubSection
EndSection

Section "ServerLayout"
Identifier "Default Layout"
Screen "Default Screen"
EndSection

-----

This forces it to use the intel driver or die. It won't try any other.
And it gives it three standard resolutions to try.
Maybe we can tweak it later, but let's see if it will
at least display something.

That's a good point. That's another thing he can try: erasing or renaming
the /etc/X11/xorg.conf file. But I suspect he's already tried that.
