Hello All,
I do not belong to this mailing-list and am not a subscriber.
I am writing this mail to you all, to get some suggestions for
the solution of a persistent problem that I have been facing
for quite some time due to which, I have not been able to setup
the multi-head configuration.
The procedure followed is in complete accordance with the
documentation for dual-head setup in linuxdoc.org -
Xinerama-HOWTO. I am not interested in setting-up Xinerama
currently. I am only intending to bring-up dual monitor display.
The steps followed are thus :
* The 2 monitors are - Acer 77
* 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 ]
* The output of XFree86 -scanpci is :
Probing for PCI devices (Bus:Device:Function)
(0:0:0) Intel 82443LX PAC Host
(0:1:0) Intel 82443LX PAC AGP
(0:7:0) Intel 82371AB PIIX4 ISA
(0:7:1) Intel 82371AB PIIX4 IDE
(0:7:2) Intel 82371AB PIIX4 USB
(0:7:3) Intel 82371AB PIIX4 ACPI
(0:13:0) Matrox MGA 2064W ----- FIRST VIdeo Card
(1:0:0) ATI card using a ATI Mach64 GDP ----- SECOND [built-in] Card.
Problem :
~~~~~~~~
The monitors work fine when, each one of the cards are individually,
a part of the configuration. When the cards are simultaneously made
a part of the configuration, the recurring problem that occurs is, that
the built-in card [ ATI Mach64 ], gets suppressed. The only card being
recognised in such a situation is the Matrox MGA ! This problem is not
allowing me to have both the monitors work in unison. The file :
/etc/sysconfig/hwconf, has two entries for the 2 "VIDEO" cards. The
"driver" field in the file indicates that the ATI-3D Card is "disabled".
Kudzu promptly removes the existing ATI, built-in card from the
configuration, thus leading to this show-stopper.
Owing to this problem of mute-suppression of one card, I am not
able to proceed with the process of configuring multi-head support.
I earnestly, request some timely suggestions in this regard, as
I have not found any online documentation regarding this kind of weird
behaviour. The few questions that rise in my mind are :
* Do motherboards have a default jumper-setting which allows only
single video-card support ? If so, achieving my setup would be a
matter of changing the jumper-settings. Acer manuals do not indicate
such a fact.
* Does this problem have to do with the fact that, one of the
video-cards is a motherboard-built-in Video card ? Does the scenario
change, when the 2 video-cards are add-on cards ?
* Does BIOS have some feature by which, support for 2 video cards can
be enabled ?
Definitely, something is missing, that I am not able to decipher.
