Created attachment 39415 [details, diff] inclusion into kernel of the i915 module, replacing i830 one, for newest xorg OK, seeing the LKML, it's a light change in xorg 6.8, using the kernel driver "i915" replacing the "i830" one: http://marc.theaimsgroup.com/?l=linux-kernel&m=109360274615220&w=2 (2004-08-27) this patch ( http://www.skynet.ie/~airlied/patches/dri/i915_linux.diff ) is NOT included in the vanilla sources of the 2.6.8 branch, neither the 2.6.9-rc1 kernel. It was included somewhere between 2.6.9-rc1 and 2.6.9-rc1-bk18. I successfully applied this patch against kernel 2.6.9-rc1 and 2.6.8 this patch provides a new kernel driver, i915, lightly different from i830. But theses two drivers aren't compatibles. in the section "Character devices", you should chose: <*> /dev/agpgart (AGP Support) <*> Intel 440LX/BX/GX, I8xx and E7x05 chipset support or <*> Intel i865 chipset support (depending of your hardware) and : [*] Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) < > Intel 830M, 845G, 852GM, 855GM, 865G ( -> called i830) <*> Intel 830M, 845G, 852GM, 855GM, 865G, 915G ( -> called i915) you shouldn't build both i830 and i915 drivers. i915 driver is for xorg 6.8.0 i830 driver is for xorg 6.7.0 this closed "bug" could be related (is the same?) to http://bugs.gentoo.org/show_bug.cgi?id=63436 , "kernel module i915 missing (causes no DRI in xorg-x11-6.8.0)"
future 2.6.9 kernel will contain the i915 driver, needed for xorg 6.8
