Direct Rendering Lost in new installation
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?
