Intel 915 and dual head display


Hello,

I've been trying to setup dual monitors with RH Enterprise 3 and Intel 915G graphics chipset (dual head - DVI and VGA connectors). I installed the Linux drivers RPM from Intel.

I have two DELL 1703 flat panel monitors (one connected to the DVI port and the other to VGA). So far, I can only get one to work.

In text mode, both of them display the same stuff, but when I run X only the DVI monitor works. I've been playing with XF86Config settings but can't get it to work. I would appreciate any help in getting two monitors to work

thanks

Lukasz

Here's what I have currently:


# XFree86 4 configuration created by redhat-config-xfree86

Section "ServerLayout"
Identifier "Default Layout"
Screen 0 "Screen0" 0 0
Screen 1 "Screen1"
InputDevice "Mouse0" "CorePointer"

EndSection

Section "Files"

# RgbPath is the location of the RGB database. Note, this is the name of the
# file minus the extension (like ".txt" or ".db"). There is normally
# no need to change the default.
# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.

# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
# Option "Xleds" "1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
# Option "XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:swapcaps"
# Or if you just want both to be control, use:
# Option "XkbOptions" "ctrl:nocaps"

i915g

Hello Tribble

I have tried unsuccessfully to get the graphics on a motherboard with the i915g
chipset properly recognized under linux.

I haven't tried for a while now, but I noticed in your XFree86 config the driver was i810,
and just wanted to direct your attention to that. Maybe you'll have more luck if you get the
i915 driver compiled and use that.

Jyst an idea, I have as stated earlier not succeeded myself.
