I'm a new Linux user, and after trying a few distributions have finally settled on Fedora Core 5. I've managed to sort out most of my system, which took a while, especially sorting out my Speedtouch 330 modem, but I'm still having problems sorting out dual monitors. I'm trying to run one Acer 17" flatscreen and one Compaq 16" CRT, both at 1280 x 1024. The Acer is the primary monitor and is running from a Radeon 9200SE, and the Compaq is running from a separate onboard Intel chipset. The built in dual monitor support in Fedora seems to do nothing but screw up the graphical interface completely, so I've tried to create an Xorg.conf file that works, but with no luck. The contents of the file created by running "X -configure" (and editing it slightly to make the mouse work) as root are included below. When I test the configuration it displays a black screen with an X as the cursor, however the cursor is limited to the primary monitor, and the secondary stays in standby mode.

Setting up tile and stipple cache:
Also, if its of any help, I just tried rebooting the system with the above Xorg.conf file and it loads only the primary monitor in very low resolution, (800 x 640 if I remember right) with the colours set to "thousands of colours" as opposed to millions.
ah sorry I meant to say "more /var/log/Xorg.0.log | grep -B2 -A2 WW", the square brackets are special characters to grep.... anyway, I can't see any useful info there, can you turn it around and get the i810 card to work as the primary device? I can see what you are trying to do but have never tried it myself (only 1 3d card in my machine).
Also could you post the output of "more /var/log/Xorg.0.log | grep -B2 -A2 WW" just in case the previous command missed anything.
