Cuz auto-login on Gnome without a display just doesn't work fsr...
sudo nano /etc/default/grubUpdate the GRUB_CMDLINE_LINUX_DEFAULT variable in this file to have one of the display connectors always active.
ls /sys/class/drm/ # shows a list of available display connectors prefixed with 'card-'Pick any one and update the GRUB_CMDLINE_LINUX_DEFAULT variable like so:
# ...
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=HDMI-A-1:1366x768e"
# ...Here,
e= enabled and1366x768is the connected display resolution
Then run:
sudo update-grubThen reboot. Done!
