Ro resume from suspend and no grub menu

[Autodave]

New machine running Win11. 2TB nvme. I installed Xubuntu on a partition of 200G. Win11 is still good and machine boots to Win11. Grub does not appear at all. I can boot into Xubuntu 24.04 by going into the boot menu and picking it. Don't know if this is related, but once Xubuntu goes into suspend more, it will not wake up. All that I get is a cursor in the middle of the screen. I can move the pointer around, but that's all.

Just a thought - as UEFI Bios booting is not compatible.
Did you install Xubuntu in bios mode ?
Boot Xubuntu and execute:

[ -d /sys/firmware/efi ] && echo UEFI || echo BIOS

will tell you if you're booted via UEFI - or Not.

Maybe - Oh Noes

[Autodave]

~$ [ -d /sys/firmware/efi ] && echo UEFI || echo BIOS
UEFI

Autodave; Well

Next thought - what does grub think ?

sudo update-grub

in the process ...

[Autodave]

Nope....booted right inti Win11.....no grub.

Can you show us /etc/default/grub?

I have that line:

# If your computer has multiple operating systems installed, then you

#GRUB_DISABLE_OS_PROBER=false

[tea for one]

I have that line:

Indeed, you do.

#GRUB_DISABLE_OS_PROBER=false

But the line has the comment symbol #, which renders it inactive.
Can you remove the comment symbol and update-grub?

Also, change the following:-

GRUB_TIMEOUT_STYLE=menu # change hidden to menu 
GRUB_TIMEOUT=5 # change 0 to 5
