Re: secondary graphic card has no memory

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

Hello...

I had a similar problem with a MGA mystique board, with a 2.4.25 (i386)=20
kernel : the board was not correctly activated in PCI. And X failled to=20
activate it.

My problem was that I was using the hackvideo stuff. I don't think you ne=
ed it=20
with a patched XFree. (cat /proc/bus/pci/hackvideo )

Do you manage to have a running Xserver driving both cards, without any=20
prefbusid ?

Does lspci returns the same before and after you start the X server ?
