If I'm parsing Eric's analysis correctly, the attached patch > along with the other items he pointed out, may do it. Apply the patch > to agp_i810.c and see if it makes a difference. Unfortunately, the patch made no difference. Eric said in above message: "The gtt_size detection is broken, though. We should have gtt_size ... equal to zero on this hardware" Your patch set the gtt_size to zero for the i965, not for the G33. So I modified the file to set the gtt_size to 0 for the G33 instead. This did have an effect. Instead of=20 agp0: <Intel G33 SVGA controller> on vgapci0 agp0: detected 7676k stolen memory agp0: aperture size is 256M I now get agp0: <Intel G33 SVGA controller> on vgapci0 agp0: detected 8188k stolen memory agp0: aperture size is 256M Unfortunately the result is still the same: (II) intel(0): xf86BindGARTMemory: bind key 1 at 0x006ff000 (pgoffset 1791) (WW) intel(0): xf86BindGARTMemory: binding of gart memory with key 1 at offset 0x6ff000 failed (Invalid argument) Fatal server error: Couldn't bind memory for front buffer I'm attaching my patch in case you find it usefull.
