Hi, Michel, We tried xfree86 4.2.0. In 4.2, doFramebufferMode has been set to TRUE. But no image displays on AGP card. Is there any other place where X disables the AGP card(primary card) that X doesn't use?
It would appear that somewhere in the Xserver code the PCI bus (and AGP) is being scanned for graphics cards (by device class?). Can we modify that code so that the AGP card will not be detected or so that the server behaves as though there is no AGP card present in the machine? If so, do you know where we should look in the code to do such a modification? Thanks in advance, jing --- Michel D�nzer <[EMAIL PROTECTED]> wrote: >The X server disables graphics chips it doesn't use >because they can cause problems otherwise. > Look at > xc/programs/Xserver/hw/xfree86/common/xf86Bus.c, it > might be enough to hardcode doFramebufferMode to > TRUE. >The initial question is as follows: >I have two graphic cards in my box, one is ATI Rage >XL(PCI) and one is ATI Radeon VE QY(AGP).
