Xorg configuration & DRI

Hello chaps.

OK im configuring X to a portable system, so to do this is will use diffrent graphic adaptors (one might be nvidia, the other ati and so on)

so i have my Xorg.conf setup with 4 devices (the first is ati, second nv, third inten, forth vesa)

now when loading on machine with an ati card i get the following in my log, its the only error in there and i was just wondering what it was. Iv not booted onto anything other than machines with ati cards in so i cant tell you if it dose it for other venders.

drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is -1, (No such device or address)
drmOpenDevice: open result is -1, (No such device or address)
drmOpenDevice: Open failed
[drm] failed to load kernel module "radeon"
(EE) RADEON(0): [dri] RADEONDRIGetVersion failed to open the DRM
[dri] Disabling DRI.

can anyone shed some light on this for me?

thanks

Re: Xorg configuration & DRI

I can't shed light on the error but I can tell you that if you use the same xorg.conf for different video boards, you may end up with headaches.  For one example, taking that DRI line, I know for a fact that this line needs to be removed from nvidia configs & usually present for ati's:

Load "dri"

This is also true for another line that specifies using 0666 mode (Mode "0666"), it is usually present for ATI cards & the Nvidia ones can't have it in the config or it throws a hissy fit.

Re: Xorg configuration & DRI

Thanks MoonSwan,

That was helpfull for me in the long run.

what iv done is made 4 diffrent xorg.conf files (xorg.conf.ati, xorg.conf.nvidia and so on)
and iv made a small bash script that works out what adaptor is installed. this script will be ran at boot

Edit:
just for those peeps also wanting this

#!/bin/bash

echo "Finding adaptor type"

set `/usr/sbin/lspci`

VENDOR="vesa"

for CURRENT in $*
do
    if [ $CURRENT="ati" ]; then
        VENDOR="ati"
        break
    elif [ $CURRENT="nvidia" ]; then
        VENDOR="nvidia"
        break
    elif [ $CURRENT="intel" ]; then
        VENDOR="intel"
        break
    fi
done

echo "Using $VENDOR driver"

if [ -f /etc/X11/xorg.conf ]; then 
    rm -f /etx/X11/xorg.conf
fi

case $VENDOR in
ati)
    cp /etc/X11/xorg.conf.ati /etc/X11/xorg.conf
    ;;
nvidia)
    cp /etc/X11/xorg.conf.nvidia /etc/X11/xorg.conf
    ;;
intel)
    cp /etc/X11/xorg.conf.intel /etc/X11/xorg.conf
    ;;
*)
    cp /etc/X11/xorg.conf.vesa /etc/X11/xorg.conf
    ;;
esac

echo "Configuration file set"
