Xorg log file

On Lenovo S10-2 laptop hardware rendering fails, even though documentation says it is supported: http://ark.intel.com/products/chipsets/30439

glxinfo | grep -i render says
direct rendering: Yes
OpenGL rendering string: Software Rasterizer

This is because the Xorg.log has an error in it:
(II) intel(0): direct rendering: Failed
See log file attached.

Are you sure your FreeBSD kernel has the DRM support for this card?

Comment 2 Yuri 2012-03-13 23:04:40 UTC

FreeBSD drm.ko kernel module is loaded.
Device in question is Intel (vid=0x8086 pid=0x27ae) is listed as supported in drm.ko source. Here all Intel 945* cards are listed as supported in drm_pciids.h:
        {0x8086, 0x2772, CHIP_I9XX|CHIP_I915, "Intel i945G"}, \
        {0x8086, 0x27A2, CHIP_I9XX|CHIP_I915, "Intel i945GM"}, \
        {0x8086, 0x27AE, CHIP_I9XX|CHIP_I915, "Intel i945GME"}, \

Comment 3 Yuri 2012-03-13 23:13:54 UTC

Also device /dev/dri/card0 exists, and command "chown root /dev/dri/card0" succeeds. I am not sure why xorg prints:
Failed to change owner or group for file /dev/dri/card0! 2: No such file or directory

Comment 4 Yuri 2012-03-13 23:40:23 UTC

Now I see that drm.ko isn't loaded at the time of xorg initialization, hence those errors about /dev/dri/card0. It was loaded later, not sure how.

However the direct rendering failure persists. Please see the new Xorg log file with the warnings in it:
(WW) intel(0): drmDropMaster failed: Unknown error: -1

and also another subsequent warnings:
(WW) intel(0): ESR is 0x00000011, page table error, instruction error
(WW) intel(0): PGTBL_ER is 0x00000010, display A pte
(WW) intel(0): Existing errors found in hardware state.
