That made no difference. Then I did "grub2-mkconfig". Still no difference.
Try GRUB_DISABLE_SUBMENU=true The documentation could be out of date. That's what's in my /etc/default/grub file, and I commented it out in order to get the style of grub.cfg *with* submenus, and that worked. You do have to regenerate the grub.cfg file in order for these settings to take effect, and you have to do it in the /boot/grub2 directory with the -o command, grub2-mkconfig -o grub.cfg You probably did it this way, but it isn't clear to me from your description, so I thought I'd say it again.
Try adding the entry GRUB_GFXPAYLOAD_LINUX=text to the /etc/default/grub file. You might have to play with this a little. To examine the possibilities look in the documentation for grub2 options about GFX using pinfo grub2
I couldn't find anything about GFX, GRUB_GFXPAYLOAD_LINUX, or GFXPAYLOAD in the pinfo output. I found some documentation in the GNU GRUB web site. Based on that, I tried "auto" on the right side of the '='. No difference, even after re-running grub2-mkconfig. It's not the text in the grub menu or the grub shell that I'm trying to change. It's the text of the boot logging that shows up after the grub menu goes away (times out), or after I hit the enter key to select "Fedora" for booting. Is that what GRUB_GFXPAYLOAD_LINUX controls? The GNU documentation gave no examples (that I saw) of what to put on the right side of the '='. What goes there?
All of these settings are under Configuration -> Simple Configuration from the main menu for pinfo grub2. If I understand what you are saying correctly, yes, that is what GFXPAYLOAD controls.
If you changed those in the /etc/default/grub file, and ran the above command again, and it didn't change the boot messages, then that isn't the setting you need. Try, order matters, GRUB_GFXMODE=1920x1080,1600x900,1280x720,1024x576,auto GRUB_GFXPAYLOAD_LINUX=keep The early boot is problematic because the video modes available to grub2 are restricted, so you might not be able to get what you want there.
