 Posted: Fri Dec 24, 2004 4:43 pm Post subject: framebuffer and 3d acceleration with IGP 340M? |
 |
|
Hi there,
I have a radeon IGP 340M card, which uses dri to get 3d acceleration with xorg. I have set up gensplash and have configured the kernel framebuffer, but when I use the framebuffer, 3d acceleration does not work properly due to AGP being occupied.
I would really like to use framebuffer but will give it up if I can't get 3d acceleration with it.
Is it possible for me to get the best of both worlds?
Many thanks, Matt |

That's strange. I have the same board, but not the same problem. Which driver are you using for framebuffer? Have you tried with vesa-tng (which should be included in the lastest gentoo dev-sources)? What is the exact error message? Are you using dri and agp drivers compiled statically in the kernel or as modules?

My log says that direct rendering is enabled, but:
mdke@kallisto mdke $ glxinfo
name of display: :0.0
Segmentation fault
And this is from my log:
(WW) RADEON(0): Failed to set up write-combining range (0xd8000000,0x4000000)

Modules. I've added the AGP module to autoload.d/kernel2.6 but not radeon. Lsmod shows that the radeon module is enabled, but I will try adding it to the autoload list and report back.
Thanks again for your help. |

Are you using udev by chance? I've had problems with recent udev+radeon-dri modules. Try to compile AGP and DRI support directly into the kernel.

Ok i've tried compiling the drm-radeon driver into the kernel, but still the same result with glxinfo: Segmentation Fault.
In fact I've now tried both with and without the framebuffer in the kernel with the same problem, so I suppose that this is not the issue. It's obviously a udev and drm-radeon issue. I'll scour the forum/bugzilla. In the meantime, any other ideas? |

whoops. Solved this by putting:
Section "DRI"
Group 0
Mode 0666
EndSection
in /etc/X11/xorg.conf. Can't believe i didn't notice this earlier. Sorry all |
