I have blacklisted vga16fb via adding [ blacklist vga16fb ] to
/etc/modprobe.d/blacklist-framebuffer.conf and verified with [ lsmod |grep -i
vga16fb ] and [ hwinfo --gfx |grep -i vga16fb ] that it is not present (I hope
that was sufficient?).

Now, if starting with a xorg.conf without error I receive the same result as
before - blank screen with a non blinking cursor in the upper left, but
terminals accessible.

So as far as I can see, blacklisting vga16fb does not make any difference. I
still need an intentional error in xorg.conf to make X working. Do you need new
log files for the case with vga16fb disabled?

Best regards, Michael
