I can't think of a good solution here, but if you would like the same "safe graphics" mode that also happens to disable the GPU, then you can edit /etc/default/grub and change:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
and then run:
sudo update-grub
and reboot. Though performance will be poor.
