Hello all,
I am extremely grateful to everybody on the mailing-list who
replied with very valuable and timely suggestions in order to
help me configure a multihead setup.
I finally succeded & wish to share with you all, the
observations that I made in order to achieve the multihead
setup:
Observations:
=============
* I was told that the built-in Video Card [ ATI - (1:0:0) ], was
being treated as Secondary and the add-on Card [ Matrox MGA
2064W (0:13:0) ], was being recognised as a Primary Card, in
my setup, which could be the cause of suppression and
mal-behaviour of the built-in ATI card.
Another suggestion that came forth in this aspect was
that of changing the jumper settings on the Matrox card, used
to disable VGA and make it behave like a Secondary Card.
[Incidentally, only Matrox comes with such a jumper setting. ]
* Also, the entry - Load "int10", was suggested to be added in
XF86Config-4, which is said to cause the secondary card to get
initialised. [ The "XFree86 -configure" does not generate this
entry automatically. ]
* Also, frame-buffer device-driver was not essential to the
multihead setup.
Steps :
======
I followed the above observations in letter & spirit :
* Changed the jumper-setting on the Matrox Card to "Disable
VGA".
* Added the entry 'Load "int10"' in XF86Config-4.
* Did a fresh install of the kernel [ with no frame-buffer
device-driver ].
Final Setup :
===========
* XFree86 -scanpci :
(0:13:0) Matrox MGA 2064W
(1:0:0) ATI card using a ATI Mach64 GD
* The built-in ATI card is no longer suppressed. In fact, the
console shows up on the monitor connected to the ATI.
- Thank you very much for having been so instrumental in solving my
problem.
