Re: Two Nvidia cards, and black screen

[<han...@sa...>]

Hi,

I noticed the closed source nvidia driver has the following option:

Option "UseInt10Module" "boolean"

    Enable use of the X Int10 module to soft-boot all secondary cards,
    rather than POSTing the cards through the NVIDIA kernel module.
    Default: off (POSTing is done through the NVIDIA kernel module).

I tried using this option, first on one , then one the other, and=20
finally on both cards, but to no effect (other then some error message=20
about accessing the vga bios on one card).

Am I still correct to assume that at least in theory it would be=20
possible to modify the int10 module (whereas you have modified the=20
radeon driver) to get the around the problem?

I will try to use a modified nv driver as you suggested later today.

Thanks for all your help!
