Re-filing here so hopefully doesn't get lost in the transition.
T500 laptop. I tried disconnecting LVDS screen and connecting VGA output to external monitor - libreboot and GRUB menus are not displayed there, although FDE unlocking (typing password blindly) and booting does work.
I have a T500 with broken laptop screen, would like to get VGA output for Libreboot/OSBoot to control boot process, play with boot parameters, install distros etc.
Is it possible/feasible?
