Description Ariel Barreiro 2006-07-09 19:31:06 UTC

I am trying to get my Intel 945GM graphic adapter work with DRI and I think the
i915 is not recognizing my card. I went through the troubleshooting guide in
your wiki and apparently it's not being probed. I tried the latest cvs drm and
i915 drivers.

this is my agp and drm kernel output:

Linux agpgart interface v0.101 (c) Dave Jones
agpgart: Detected an Intel 945GM Chipset.
agpgart: Detected 7932K stolen memory.
agpgart: AGP aperture is 256M @ 0xc0000000

[drm] Initialized drm 1.0.1 20051102
[drm] Initialized i915 1.5.0 20060119 on minor 0:

When I launch my xorg 7 with the i810 driver, apparently DRI is working:

(II) I810(0): [drm] installed DRM signal handler
(II) I810(0): [DRI] installation complete
(II) I810(0): direct rendering: Enabled

but the glxinfo | grep rendering tells me it's not

direct rendering: No

Do this...

LIBGL_DEBUG=1 glxinfo 

and look at the start of the output for error messages.

First of all thank you for that little tip. I found it on the net and did it
before but somehow I didn't notice on the error.

At first it was an easy thing, no i915_dri.so driver. Then after installing the
debian testing mesa-dri pacakge there was an error about a structure size. So I
checked out everything from your cvs (drm and mesa driver) and compiled
everything and now I have everything working. I am quite happy, I have my
glxgears run very smooth of my brand new dell 640m :).

Now, just as comment that may be of some use for you I tested the new google
earth beta which runs in DRI mode and I guess it does make an intense use of it
and I found two things:

Using the drm and i915 driver from the 2.6.17.3 kernel and the latest dri
driver, glxgears works but google earth refuses to work.

Using the same thing without the kernel drivers but with the latest source
(1.4.0 of i915 on the kernel and 1.5.0 out fo the cvs) google earth runs
perfectly. Actually it runs quite good but after a while of using it, I think
something happen, either with the driver or with google earth (it's in beta) and
it starts to work real slow, almost as without any dri driver, but there is no
output on console.

Thanks!
