Lost direct rendering after kernel upgrade

Ramark · 04-16-2006, 11:31 AM

I downloaded kernel 2.6.16.5 and after i installed it and fixed some problems, one remained unsolved. With kernel 2.4.31, typing 'glxinfo|grep direct' would say that direct rendering is on. When i boot kernel 2.6, it is off. I am using same xorg.conf for both kernels and modules agpgart, mga and drm are loaded. Graphics card is Matrox G400.

double-check and make sure you built
the module into your kernel...

I guess you have been using a binary driver before (I am not familiar with recent Matrox cards, but AFAIR they used to ship them with binary only drivers in the past)? If so you need to reinstall this driver for your new kernel version.
you may compare the contents of
/lib/modules/<old-version>/kernel/drivers/char/drm/
with
/lib/modules/<new-version>/kernel/drivers/char/drm/

Module by definition is something that is not built into kernel

Enyway, which driver you ment to build into kernel? I guess it is one of gpgart, mga and drm.

Look, that driver matrox ships is not for kernel, it's fot X Windows System. XFree86/xorg have its own matrox driver i guess matrox driver is based on. I also tried that matrox driver, downloading and installing newest from their site, but it didn't help.

Kernel mga driver is part of original kernel, so i compiled that version that goes with 2.6.

Sure, the gfx-driver is for X. However, they need to talk to the kernel anyway. Again, I don't know the Matrox card (nor Slack), but at least in the past the G400 card wasn't DRI-supported by X.org/Xfree.

Did you compile the module under your new kernel?
What driver does glxinfo tell you is being used?

Good luck!

It is suppported, becouse it worked with 2.4 kernel.

I didn't compile it, i used precompiled binary. I will try it, howewer i doubt, since i guess xorg driver should work with 2.6

I don't see driver mentioned in output of glxinfo, see yourself

Check if the binary driver from Matrox does support 2.6.x. If it supports 2.4 it is unlikely to run smoothly under 2.6.

You are using the Xorg-Mesa-Driver which apparently doesn't support 3D-support for your card.
The driver name for the Matrox card is mga (you'll find that one in your xorg.config).
Probably, the driver needs to be compiled with access to your new kernel-headers (do you have a symlink /usr/src/linux to your kernel sources?).

See
http://www.matrox.com/mga/support/dr...les/lnx_43.cfm
Recompile the driver for your new kernel
Read the release notes:
ftp://ftp.matrox.com/pub/mga/archive...driver_4_3.txt
It says "DRI requires a 2.4.x kernel with "agpgart" support.". So I cannot promise success. I found a posting telling that 2.6.16 does NOT work wereas 2.6.15 does. It seems to reuire a workaround though: " a workaround is to add the Option "OldDmaInit" "true" in the Device section of xorg.conf for the card as a workaround. My problems were solved by this setting for the card, an MGA G400 DH AGP." (http://lists.debian.org/debian-kerne.../msg00008.html)
and for further options the Xorg.wiki:
http://xorg-annarchy.freedesktop.org...doc/mga.4.html

Good luck

Binary driver from Matrox makes me problems with text mode console when using framebuffer or SVGATextMode, so i downloaded source from ftp.slackware.com and started script x11.SlackBuid.

I tried 2.6.15 and it also didn't work. There are differences in error messages from dnmesg:

linux-2.6.13
linux-2.6.15
Linux-2.6.16.5

2.6.13 is one from Slackware CD2.

Will this script use kernel headers from /usr/src/linux, since there are still old headers in /usr/include? I didn't install 2.6.13 headers since it reads in README it is not advisable.

If it worked with 2.4, why wouldn't with 2.6?

Ramark · 04-20-2006, 08:06 PM

What i least expected solved the problem. I patched kernel to 2.6.16.9 and now glxinfo says direct rendering yes

Thanks to all who was assisting me.

Previously i tried to recompile mga_drv.o with new kernel, but the binary was not changed.
