Hello all,
I received a lot of clues in the form of questions and
suggestions.
I am still in doldrums, so far as multihead setup is concerned.
Based
on the feedback from members who responded, I am providing
additional
information to get more suggestions in order to solve this
problem.
Recap of the setup/problem:
----------------------------
* 2 monitors - Acer 77c
* The PC is an AcerPower S Series
* The 2 Video cards are :
ATI Card Mach 64 [ built-into the motherboard ]
Matrox MGA 2064W [ Add-on card - PCI slot ]
* XFree86 -pci recognizes both the cards and allots BusIds.
(0:13:0) Matrox MGA 2064W ----- FIRST
VIdeo Card
(1:0:0) ATI card using a ATI Mach64 GDP ----- SECOND
[built-in].
* Kudzu repeatedly reports the absence of the built-in card [ATI]
and
prompts the user to remove from the configuration.
Problem :
-------
Not able to bring-up multihead support.
Additional information :
----------------------
XFree86 -version : XFree86 Version 4.0.3 / X Window
System
Machine architecture : i386
New observation :
----------------
* Frame-buffer device-driver needs to be a part of the compiled
kernel
in order to observe multihead behaviour.
* The monitor connected to ATI [built-in AGP Card], indicates
"Out of Range" with a glowing green light. This is a new
development
as the message earlier was "No Signal" with a blinking orange
light.
The console which is displaying boot-up messages hangs with the
error :
" atyfb: 3D Rage Pro (BGA, AGP, 1x only) [0x4744 rev 0x7c] 512k
RESV,
14.31818 MHz
XTAL, 230 MHz PLL, 100 Mhz MCLK "
The above are the new pieces of observation made in my quest to
setup
a multihead configuration.
In order to ease the investigation, I am including the# XFree86
XF86Config-4
file :
#XFree86 4.0 configuration generated by Xconfigurator
