Re: Debian 11 Set Gnome Security Login Screen Resolution?
I believe it is inherited from Grub, so check
Change the last line to the size of your monitor and don't forget to update Grub.
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

Re: Debian 11 Set Gnome Security Login Screen Resolution?
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

done
# reboot
Works! Thanks for the response and assistance.
