Re: AW: Multiple text consoles

[ludovic p. <pl...@nn...>]

Your work is really interresting !

Does your driver actually disable NV vga ioports ?=20

In my case, that could be helpfull :

My computer runs with a MGA and a NVIDIA board. Sometime, the nvidia head=
=20
seems to be messed up when X starts on the MGA board. I believe that the =
X=20
mga driver directly accesses the VGA ioports which belong to the NV board=
.

So, with nvvgacon I may have a vga console on the NV card which would not=
=20
require VGA ioports access. If your driver disable VGA ioport on the NV=20
board, I'll be sure that no more conflict will arise !
