<p> 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:</p>
<p>GRUB_DEFAULT="Ubuntu, with Linux 4.15.0-48 generic"</p>
<p>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. <br>
</p>
<p>So really just an update.</p>

<p>Hi a,</p>
<p>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!</p>

Hi Brian,<br>
<br>
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. <br>
<br>
sudo add-apt-repository ppa:danielrichter2007/grub-customizer ;
sudo apt update ; sudo apt install grub-customizer ;
grub-customizer<br>
<br>

<br>
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<br>
<br>
I also forgot to tell you to run update-grub after you edit
/etc/default/grub<br>
<br>
So this is what you should do.<br>
sudo cp -p -v /etc/default/grub /etc/default/grub.bak<br>
sudo nano /etc/default/grub<br>
(Change GRUB_DEFAULT=0 to GRUB_DEFAULT="Ubuntu, with Linux
4.15.0-48 generic" ) (Make sure you include the double quotes,
"")<br>
(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)<br>
sudo update-grub<br>
sudo systemctl reboot<br>
<br>
That should force that particular kernel to load on it's own,
without a grub menu at boot time. <br>

<p>Many thanks Jared,</p>
<p>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?</p>
<p>Cheers</p>

Hi Brian, <br>
<br>
I think this should work.<br>
<br>
sudo cp -p -v /etc/default/grub /etc/default/grub.bak<br>
sudo nano /etc/default/grub<br>
(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)<br>
sudo systemctl reboot<br>
<br>
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<br>

<p>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.</p>
