Hi,

Since last one month I had been trying to get the 3D acceleration working for my Intel 82852/855 GME chipset under Debian with Xorg under GNOME. Finally, after loads of researching, I found that I had to enable the agpgart and the drm for i915 chipset in the kernel. I downloaded the 2.6.13 kernel sources and did that. I compiled the kernel and booted the new kernel and I got the 3D accelerated(ran the glxinfo and notied that direct rendering was enabled). I stored the .deb package of the new kernel as I had used to the make-kpkg method to compile the kernel.

Now, I did a fresh intallation of the debian on another machine(exactly indentical in terms of hardware) and I install the kernel(2.6.13 with 3d support) on this machine. But to my disappointment, I found that there was no 3d Accelaration.

What could be the possible reason? I also tried copying the xorg.conf file from my first machine to this, but it did not help. Could it be the reason, that I may have installed some extra packages on my first machine(while doing research) which I did not on the second machine?

While this doesn't answer your question directly, I had a similar problem with installing a kernel from the .deb package. Only when I did it it was on the same computer. I had to re-install linux (Actually, windows, but lost the linux partition) and for some reason the kernel package didn't work on the exact same pc. So my suggestion: re-compile. it only takes about an hour (Depending on your machine, of course).

thanks for the info. Actually I tried what you had suggested couple of hours ago and I ended up with same results. It did not help.

The output of lsmod is exactly same on both the machines,but still the direct redering is enabled only on the first machine. This is really frustating.I am using the same verison of Xorg and Gnome.

Anyone?

The problem was solved. I had to install the libmesa-dri package which was missing. After installing I got my direct rendering back.
