Hi guys
I’m trying to get dual monitors on my Dell Optiplex GX270. It has on-board Intel 865G chipset with a VGA socket and a little Silicon Image Carrera 164 DVI extension.
Currently I have it in dual boot, OpenSUSE and Windows XP. The two monitors seem to be working fine in Win, but I only managed to get one of two working at the same time.
My current /etc/X11/xorg.conf:

I tried changing the config manually as found on google, etc, creating two Monitor, two Screen entries. Unfortunately, it either had no effect or the X server did not start.
I am not quite sure about the SaX options in the config. Here is what I’ve got in /var/log/Xorg.0.log:
(II) intel(0): RandR 1.2 enabled, ignore the following RandR disabled message.
(**) Option "dpms"
(**) intel(0): DPMS enabled
(II) intel(0): Set up overlay video
(II) intel(0): direct rendering: Disabled
(WW) intel(0): Option "SaXDualHead" is not used
(WW) intel(0): Option "SaXDualMonitorVendor" is not used
(WW) intel(0): Option "SaXDualOrientation" is not used
(WW) intel(0): Option "SaXDualResolution" is not used
(WW) intel(0): Option "SaXDualMode" is not used
(WW) intel(0): Option "SaXDualHSync" is not used
(WW) intel(0): Option "SaXDualMonitorModel" is not used
(WW) intel(0): Option "SaXDualVSync" is not used
(WW) intel(0): Option "SaXExternal" is not used
(WW) intel(0): Option "PreferredMode" is not used
(--) RandR disabled
Here’s a cut from /var/log/Xorg.0.log where it detects the Sil164 extension:
(II) intel(0): I2C bus "CRTDDC_A" initialized.
(II) intel(0): I2C bus "DVODDC_D" initialized.
(II) Loading sub module "sil164"
(II) LoadModule: "sil164"
(II) Loading /usr/lib/xorg/modules//drivers/sil164.so
(II) Module sil164: vendor="X.Org Foundation"
compiled for 1.4.0.90, module version = 1.0.0
ABI class: X.Org Video Driver, version 2.0
(II) intel(0): I2C bus "DVOI2C_E" initialized.
(II) intel(0): I2C device "DVOI2C_E:SIL164 TMDS Controller" registered at address 0x70.
(II) intel(0): Output TMDS using monitor section EXT
(**) intel(0): Option "PreferredMode" "1280x1024"
Finally, I tried to use xrandr manually:
$ xrandr --output VGA --auto --left-of TMDS
xrandr: cannot find crtc for output VGA
However, I can switch from one output to another using xrandr:
$ xrandr --output TMDS --off
$xrandr --output VGA --auto
Any ideas/suggestions/help are much appreciated!
