I believe it is inherited from Grub, so check

Code: Select all

etc/default/grub

Code: Select all

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

...

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
GRUB_GFXMODE=1366x768
Change the last line to the size of your monitor and don't forget to update Grub.

Right... This is what worked for me. Since I was working with a virtual machine, I had to make sure its configuration allowed for sufficient memory and determine which monitor was being used.

Added and/or changed the following to /etc/default/grub...
#----------
#
# Get Connected Monitors?
# for p in /sys/class/drm/*/status; do con="${p%/status}"; echo -n ${con#*/card?-}: ; cat $p; done
# Virtual-1: connected
# Virtual-2: disconnected
#

#GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=Virtual-1:1920x1080"

#
#----------

#---------
#
# For VMware Machine, Ensure Sufficient Video Memory Size...
#

GRUB_GFXMODE=1920x1080x32,1680x1050x32,1600x900x32,1280x800x32,1024x768x32,auto
GRUB_GFXPAYLOAD_LINUX=keep

#
#----------

Of course had to update grub configuration after the above changes.

# update-grub
Generating grub configuration file ...
Found background image: /usr/share/images/desktop-base/desktop-grub.png
Found linux image: /boot/vmlinuz-5.10.0-10-amd64
Found initrd image: /boot/initrd.img-5.10.0-10-amd64
done

# reboot

Works! Thanks for the response and assistance.
