I'm including my last email on this Grub problem (I think that's what it is). The problem exists still. I did find a syntax error that I thought might be the issue. I had this in the config file: GRUB_DEFAULT="Ubuntu, with Linux 4.15.0-48 generic" I was searching the how-tos, etc and the correct syntax has a dash and not a space between "48 generic" so "48-generic". I also changed 48 to 55, the last and most current of the 4.15s. Didn't change though it does allow a reboot, just doesn't reboot into anything but the splash screen. Booting on it's own boots a 4.18.x kernel with the improper and not reconfigurable resolution. So really just an update.

I' including my grub file as it now exists. After implementing the changes my machine shuts down in a reboot but loads only the splash screen and no further. If I boot it as opposes to reboot, I get the newer kernel and the bad graphics. If I choose, manually, the 4.15.0-48 kernel, it boots normally with the proper resolution. Here's my grub file and thanks again!

Hi Brian,
If you are able to get to a x session (GUI) I would adjust grub with grub-customizer. You can do this from command line, however, it would mean adjusting /etc/grub.d files.
sudo add-apt-repository ppa:danielrichter2007/grub-customizer ; sudo apt update ; sudo apt install grub-customizer ; grub-customizer
https://www.fosslinux.com/4300/how-to-edit-grub-bootloader-and-remove-unwant...
However, I would probably would just tell grub to not display the menu. As long as you're going to manually enter the GRUB_DEFAULT option in /etc/default/grub
I also forgot to tell you to run update-grub after you edit /etc/default/grub
So this is what you should do. sudo cp -p -v /etc/default/grub /etc/default/grub.bak sudo nano /etc/default/grub (Change GRUB_DEFAULT=0 to GRUB_DEFAULT="Ubuntu, with Linux 4.15.0-48 generic" ) (Make sure you include the double quotes, "") (Also add this any where in the same file, just make sure it has it's own line to itself, GRUB_DISABLE_OS_PROBER=true ) (Ctrl + O then Ctrl + X to save and exit) sudo update-grub sudo systemctl reboot
That should force that particular kernel to load on it's own, without a grub menu at boot time.

Many thanks Jared,
I will give this a shot tomorrow. I don't think it will fix the restart issue but perhaps this kernel is magical. I will find out. Any idea why my user name would show up in the Bios boot order? Do you think it's something I could delete safely?
Cheers

Hi Brian,
I think this should work.
sudo cp -p -v /etc/default/grub /etc/default/grub.bak sudo nano /etc/default/grub (Change GRUB_DEFAULT=0 to GRUB_DEFAULT="Ubuntu, with Linux 4.15.0-48 generic" ) (Make sure you include the double quotes, "") (Ctrl + O then Ctrl + X to save and exit) sudo systemctl reboot
See if that will do what you're asking. TBH I'm use to systemd-boot, not grub. It's been a while since I've used grub. If that change broke things, you can move the grub.bak file back to /etc/default/grub

I tried a bunch of fixes but found one that worked! I edited / "etc/default/grub" and manually changed the screen resolution to 1366x768. that may have worked so I shutdown (hard) and booted (after, once again, moving my user name down in the boot order in the Bios) and successfully bringing up the Grub menu. I arbitrarily picked 4.15.0-48 generic and lo and behold Wifi, sound, resolution, xrandr output shows many screen res. options and things seem to be ok, for now. I would like this kernel to be the first choice for booting. I'm sure there is a simple way to do this. can anyone enlighten me? I would really appreciate it but I can also search and I'm sure there is a solution to be found.
Talk about Ghosts in the Shell!!
Thanks for your indulgences!
