Still Grub issues

     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.

Hi a,

I finally got around to this and implemented your suggestions. 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!

Brian
