Big x-server probs setting up matrox g550 & acer al732

[Starik]

Hi,
after using Debian woody for some months I decided to put gentoo on my computer (duron 1,2;1024MB;matrox g550;30GB maxtor;80GB samsung). So I installed & configured my system with stage1. Everthing was fine until I started to set up the X-Server. First I emerged xfree without any problems and I wrote myself a configfile for the server based on some topics in this board. My config-File is placed at "/etc/X11/XF86Config". Gentoo starts the Server without any problems (there are no error messages), BUT my monitor (Acer AL 732;17'' TFT;connected via DVI; Horizontal Freq.: 30-80;Vertical Freq.: 56-75) does not display anything but says (this acer model gives little messages about the resolution etc. that is used, when the monitor starts) "1280x1024 - 0kHz - This is out of my area" (the last sentence is translated from german - I gave my best ). So my screen is black...
What shall I do to get my x-server running? I have not installed an extra Matrox-driver or anything else, I set up my system just by the instructions of your doc-file.

hm, with normal analog connection it works, do I need special commands for running my dvi-connection?
Thanks

Here's a sample Dualhead config.
I think you will at least have to define the second device,
since a G550 acts like 2 individual gfx cards.

Check out the Matrox Linux forum at http://www.matrox.com/mga/support/forum/agree.cfm.

For DVI with the G550 you will need the Matrox binary drivers.
