Sadly when complete make -j4
after having edited /opt/media_build/backports/backports.txt
to comment out:
[6.8.1023]
# add v6.8-ccs.patch } recommended to avoid the problem below
add v6.8-spi.patch } but doesn't
add v6.8_remove.patch }
it ends like this:

The reason I am using kernel version 6.8.0-51-generic is that was the install
kernel and alloewed me to use both screens. However I edited twom lines in
grub:
# GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=10
to defer boot up until I had selected kernel version 6.8.0-51-generic and now
I only get one screen again!
I am truly cheesed off.
