I’m running an eGPU setup (cf Razer Core X Chroma eGPU). One of the problems is that when the laptop boots, the display is only on the laptop’s monitor. Meaning I can’t leave the laptop lid closed and the laptop docked.
At every boot, I need to undock the laptop, wait for it to go to Grub, select the OS, wait for it to boot and then close the lid and dock it.
It would be better if all the BIOS and boot menus (including Grub) were displayed on the external monitors.
To do this, my understanding is that I must be able to enable Thunderbolt pre-boot support in the BIOS (cf Thunderbolt - how to use keyboard during boot time - Fedora Magazine).
If that is indeed the required setting, it would be great to have it available in the BIOS.
