I did, but no answer was given except to contact help-grub list....

I found a culprit: the command linux16 in the /boot/grub2/grub.cfg. If
I change this command to linux, I can get the correct resolution
during the boot.

3 questions arise:

1- The first line of the boot message begins by "failed" in red color,
but I cannot see what has failed because the display is too fast and I
cannot stop it using the pause keys of the keyboard... How to slow
down the messages? (my system is on SSD, so the boot takes less than
10s).

2- Changing linux16 to Linux seems to not affect the boot. Am I right?

3- How to get this change (linux16 to linux) resists to updates?

Thank you.
