(T61)Ext-vga in Linux with 'intel' driver.

Has anyone gotten this to work? I've gotten it to the point that the displays will both turn on the backlight, but remain black, and then my system will hang and I have to do a hard reboot.
I've tried multiple auto-configuration tools in Ubuntu and Fedora, and manually pushing one together via the ThinkWiki website to no avail.
I've tested ext-vga just fine in Windows(ugh) XP so the hardware seems to be working.
MOD EDIT: Moved to linux forum.

What's your xorg.conf? Please use the code tags when posting. Already tried xrandr?

I tried the xrandr howto with modifying my xorg.conf and it would not work. Using system-config-display and a lot of other manual configurations would cause my system to lock up when starting X.
Here's my generic xorg.conf

Have you tried the Intel drivers from
www.intellinux.org ?

Here's the script that I wrote to enable the VGA port:
Code: Select all

xrandr=/usr/bin/xrandr
add1024 () {
$xrandr --addmode VGA 1024x768
}

}

$xrandr --output LVDS --mode $1
}
projectorOff () {
$xrandr --output VGA --off
laptopMode 1024x768
}
projectorOn () {
$xrandr --output VGA --mode $1 --rate 65 --$2 LVDS
laptopMode $3
}
clone1024 () {
add1024
projectorOn 1024x768 same-as 1024x768
}
dual1024 () {
add1024
projectorOn 1024x768 above 1024x768
}

}
dual1280 () {

}
doMenu () {
echo "0. Projector off"
echo "1. 1024x768 - clone"
echo "2. 1024x768 - dual"
echo "3. 1280x1024 - clone"
echo "4. 1280x1024 - dual"
read -p "Select a display mode [1]: " selection
doAction $selection
}
doAction () {
if [ "$1" = "0" ]; then projectorOff
elif [ "$1" = "1" -o "$1" = "" ]; then clone1024
elif [ "$1" = "2" ]; then dual1024

else echo "Invalid action specified."
fi
}
if [ "$#" = "0" ]
then doMenu
else doAction $1
fi
Maybe you can adapt this stuff to suit your needs. One thing to consider is if you use Compiz, you need your virtual screen size to be under 2048x2048 in dual-head mode. It's not as much of an issue in clone mode.

Will your xorg.conf do Xinerama?

Not sure, I don't have any experience with Xinerama.

Xinerama is deprecated in favor of XRandR in recent xorg releases.

So how do I use xrandr to extend the desktop instead of just clone? That's all I get when I use the Thinkwiki page.

I got xrandr to finally extend my desktop, via adding the "NoDRI" option to my intel card.
One last issue I have is my monitor is flashing "Out of Range" due to the rate i suppose, here's what I get from xrandr -q
Code: Select all
% xrandr -q
Screen 0: minimum 320 x 200, current 2720 x 1024, maximum 2720 x 2048
VGA connected 1280x1024+1440+0 (normal left inverted right x axis y axis) 338mm x 270mm
1280x1024 75.0*+ 76.0 75.0 70.9 59.9
1152x864 75.0 74.8
1024x768 75.1 70.1 60.0
832x624 74.6
800x600 72.2 75.0 60.3 56.2
640x480 75.0 72.8 66.7 60.0
720x400 70.1
640x350 70.1
LVDS connected 1440x900+0+0 (normal left inverted right x axis y axis) 303mm x 190mm
1440x900 60.0*+ 50.0
1360x768 59.8 60.0
1280x800 60.0
1152x864 60.0
1280x768 60.0
1280x720 60.0
1024x768 60.0
800x600 60.3
640x480 60.0 59.9
TMDS-1 disconnected (normal left inverted right x axis y axis)
How can I tell xrandr to run at 59.9 for just the one monitor? I tried xrandr --rate 60 and it blacked out my LVDS.

Solved by just switching it out with a different monitor.

Sorry for miaing your thread after asking for your conf. You could set HorizSync and VertRefresh for a second monitor in xorg.conf if you wanted. But if it ain't broke...
