on the xf86-video-intel !STABLE! (2.6) branch, direct rendering on i965GM is broken by commit 009085d314a1c2999e1408c9627e74201591fe68 Author: Kristian Høgsberg krh redhat com Date: Fri Jan 30 17:53:03 2009 -0500 Implement front buffer resize for KMS. This adds back the resize hook so we can resize the front buffer under kernel mode setting as well. The patch also pulls the drmmode_* structs from drmmode_display.h into drmmode_display.c and eliminates the header file. (cherry picked from commit 0cb87ccfe97b0e016e47dcf236fd5ce78dddfc4b) subsequently, the X server hangs on creation of a large pixmap (which probably is another bug in some less-tested codepath used only when DRI is disabled) a working driver can be constructed by reverting the following patches: 36f3136... KMS: Hook up rotated shadow buffers. cdcca95... Don't disable vga centering bit. 5a86b78... TV quirk for HP Compaq nx6310 79b0070... Fix front buffer memset() for non-KMS case. 133dd16... Un-revert the I915_SETPARAM_NUM_USED_FENCES commit reverted by accident. d349f36... Fix last-minute "cleanup" that broke the patch. 009085d... Implement front buffer resize for KMS. none of these patches fixes the problem. more information available on request of course, just need to know what to add (no outstanding error messages...)
