Hi Rava,
I had already done that! (see above)
But the final version (kernel 4.16.3) starts just as slowly!
I repeated it again.
The new link: https://pastebin.com/GPnMfDZp
In particular, after the message
(==) Using system config directory "/usr/share/X11/xorg.conf.d"
the screen stays dark for a long time.
Conclusion:
Porteus 4.0 has a very long startup time
Porteus 3.2 has a normal startup time
That's why I use Porteus 3.2 on the old computer
And that is ok for me
