How to set the Aspeed gpu as the primary gpu in a linux system?

[deephog]

I don't know if this repo is actively supported or not, but we are desperate, so I will just try it here.

We have an ASROCK server mother board which has an AST2500 integrated. We built the motherboard into a deep learning machine which has some high-end GPUs for computation. We would like to fully utilize the GPUs for computation, so we wanted to force the ASpeed gpu as the primary display.

We could not find any relative setting in the bios, and we tried changing the xorg.conf file (which we don't have a good reference of how to, we may did it wrong), none of those helped. Could you please give us some help on how to achieve our goal?

Thanks!

Hello, as i know the primary display should be configured by bios.
