Matrox G400 DRI single-head [Solved]
 

OVer ther past couple of days I have attempted getting Direct Rendering to work with my Gentoo 2.6.9-r4 Linux box with X.org 6.8.0 but to no avail. I have compiled into my kernel agpgart and my AGP chipset drivers. I have also tried a variety of things, using hte kernel DRM drivers for my matrox card, downloading and installing the drivers from matrox, but nothing seems to work.

Before I start X I have to manually load the following:

modprobe agpgart
modprobe intel-agp
modprobe mga

If I then look at my X.org log it reads the following:

As you can see when X starts it seems from the following line in the log that Direct Rendering is enabled.

However running I get the following error:
[CODE]name of display: :0.0

[/CODE}

has anyone else had this problem, or does anyone have any ideas on how to get past this? thanx in advance.

Matrox G400 DRI single-haed [SOLVED]
 

Well, i scrapped everything i had done so far and followed a how-to for S3 cards ( even though mine isnt one ) and used the DRI cvs, so now I have finally got DRI working.

Hi, I'm having the same problem with my G400 MAX, can you please tell me how solved it?

Here's Xorg.0.log:

what about all those unresolved symbol? does the matrox driver works only with XFree?

and here's the output from glxinfo with LIBGL_DEBUG=verbose:

thanks for your help :)

bye!

OK. Well, it is not exactly the same as my problem, but i will try and help as much as i can. Well, first things first, the

issue was the first thing that i fixed. What i did was run lspci | grep AGP and find my AGP chipset ( not graphics card. ). The output from this command was as follows:

The first line ( not matrox card ) was the one that i needed. I then compiled the following as modules into my kernel:

(EDIT)
forgot to mention that i read in alot of places that you also need MTRR support enabled for Direct REndering so I also had this enabled in my kernel

(/EDIT)

After editing my GRUB configureation files, and rebooting into the new kernel I had to load the intel chipset AND agpgart BEFORE starting X. This got rid of the OpenDevice error, but direct rendering still did not work.

Now if I can remember correctly ( which i think i can ) I then followed the SiS tutorial, to no real avail, but caught on and followed the tutorial from the DRI web site.

What you need to do is this ( i think ) go to http://dri.sourceforge.net/cgi-bin/moin.cgi/Building and follow the instructions for CVS install. If you are like me, i was hesitant at using CVS as i didnt want to create stuff out of my portage only installed system. However, what i did, was create a cvs directory in /home and then did everything inside the /home/cvs folder ( i.e ran all the cvs commands so I ended up with /home/cvs/Mesa /home/cvs/DRI /home/cvs/xc ). Just follow the instructions on that site. However, there are one or two little bits that confused me a little, dont know whether you will find confusing, but after completing

1.1.4 Installing over X.org or XFree86

go onto 1.1.6 and continue on. There is a little message down the bottom which relates to Gentoo users, talking about open-gl update, and how there are lotsa problems with it. I wanted Direct Rendering working REALLY bad so i jsut decided to emerge -C opengl-update before starting the process. Might make things a little easier.

Well, after all of that i just added the modules to my /etc/modules.autoload.d/kernel-2.6 like so:

agpgart
intel-agp

No need to autoload the mga module, X.org seemed to do that on it's own. Well, i think that is everything, so go through it and try to get it working. I will be glad to ( try ) and help if you run into any problems, but if it works make sure you post here and tell me :D. I would feel great if i managed to help someone else to get Direct Rendering to work.

Hi, thanks for you help, building from cvs solved the problem, now everything works :)
thanks again :)

Glad to be of help. :D
