RTFM!

So set depth to 16, and get DRI.

That is not the problem, in my case, and most likely his too, no matter WHAT i do i cannot get DRI on Slackware 10 with an i810. I got it working in Arch/mandrake/gentoo/ubuntu/debian, but never slackware. Even using the same xorg.conf file from a distro where it worked did not get it enabled.

Slackware was the ONLY distro that i could not get DRI to work on the i810.

I have pretty much given up on this. I guess I'll just use Red Hat or SuSE if I want to use #D. Otherwise, I'll just keep Slacking. Thanks everyone for your time.

I just now got OpenGL 3d acceleration working on my i810 workstation. I had to reduce the depth to 16 AND reduce the resolution to 1024x768 or less.

I actually already had DRI working all this time at 24bit depth and higher resolutions, but not 3d hardware acceleration.

I'm using Debian Stable, with 2.4.* kernel and XFree86-4, btw.

You guys might already have checked Mesa, but this is what turned out the problem on my box (and solved it)

Another option is to download the updated proprietary drivers from the Intel website and install those. There is a rpm there and I used the rpm2tgz script to convert it into a slack package and then used installpkg to install it. Works great. I've got quake3 running very nicely on my dell 700m laptop.

To find it, go to the intel site, then to their "download center" and then look under video in the left column. They have several linux drivers for various chipsets.

I'm bringing this thread back in case anybody else wonders. I figured out what the problem was with my i810 chip. I tried Slackware 9.1 which was the last release with XF86 and everything worked fine...it is only when the change was made to xorg that I wasn't be able to get dri. So, if I just want to play any 3D games under linux, I just fire up my 9.1 partition and everything works great. Thanks everyone for the help!

hi guys,

I too had the same proble of having Slackware 10.1 working with dri perfectly .....

But when I upgraded to Slackware 10.2 ... and installed the 2.6.13 kernel from testing it wouldnt work.

Then just by chance I happened to delete the 2.4.31 modules directory in '/lib/modules' and now everything works perfectly.

The only other thing I changed was i now do startx at the console ... not a KDM login ....

hope this works for other too .. if it doesnt then dont have any other clues

hi guys,

a follow up to my above post ....

I can now get direct rendering working at will.

In slackware 10.2 .... if u start with runlevel 3 ... which will take u to a console login ... and login that way it works just fine .... 24 bit @ 1024x768

But if I start with runlevel 4 .... then direct rendering in glxinfo says no ....

any ideas on what could be causing this.

Perhaps because KDM launches X as root? Did you added yourself to the video group in /etc/group?

ok ....

i have added myself to the video group ....

and now have dri working as a user ...aawesome ...

but now I have another problem ....

when i log into my user account .... and try to play movies by doing an su and typing in my root password .... the screen gets all garbled ... like screen corruption.

any idea what may be causing this.

hi body. i have some similar problems:my X server couldn't start drm. while booting my kernel loads correctly both agp interface(agpgart+intel-agp) and i830(the kernel's one, not X one) driver, so my X loads i810 module (i can't use i830 module for X because i can't compile intel sources..). but this is Xorg.0.log:

(II) I810(0): [drm] created "i915" driver at busid "pci:0000:00:02.0"
(EE) I810(0): [dri] I830DRIScreenInit failed because of a version mismatch.
[dri] i915 kernel module version is 1.3.2 but version 1.4 or greater is needed.
[dri] Disabling DRI.

here he talks about a version mismatch. i think kernel driver (2.6.8-2-686 debian repository) is too old..i need to enable direct rendering. any suggestion?

Check out my DRI thread in my sig.

I use the i810 driver, DRI smokes in glxgears at about 4000fps for all users

i've done exactly what is written. installed latest kernel, loaded modules in right order, corrected Xorg.conf, but error still remains. But what does it mean?? version mismatch?? is the latest kernel too old?? O_o

/*hi.
i've solved the version problem: i915 kernel driver is 1.4.0 version, so it runs. anyway, no dri. it is strange, dmesg doesn't return any error, but glxinfo returns this:

ERROR! sizeof(I830DRIRec) does not match passed size from device driver
libGL warning: 3D driver returned no fbconfigs.
libGL error: InitDriver failed
libGL error: reverting to (slow) indirect rendering

what is this????
*/fixed it: for debian users see it -->http://mailgate.supereva.com/linux/l.../msg53633.html
i think i'm not far by the solution..
but still remains it in Xorg.0.log:

(II) LoadModule: "GLcore"
(II) Loading /usr/lib/xorg/modules/extensions/libGLcore.so
dlopen: /usr/lib/xorg/modules/extensions/libGLcore.so: undefined symbol: __glXLastContext

(II) LoadModule: "GLcore"
(II) Loading /usr/lib/xorg/modules/extensions/libGLcore.so
(II) Module GLcore: vendor="X.Org Foundation"

how can i fix it?
