------- Comment #13 from prein...@logic.at 2009-01-27 00:23 ------- Haaa, no, these patches are not necessary, neither are any other patch. The real problem was somehow a different .config. With 2.6.29-rc2 suddenly my i915 drm kernel module was lost, and only with very strange playing around and hand editing of the .config file and activating CONFIG_FB I got it (the drm module) back (btw, I never had CONFIG_FB set till 2.6.28 and it always had worked to get i915 drm module). I had to add quite some settings and it looks like one of those made the change: That is the diff from old to new config: @@ -1358,16 +1358,78 @@ # CONFIG_DRM_TDFX is not set # CONFIG_DRM_R128 is not set # CONFIG_DRM_RADEON is not set -# CONFIG_DRM_I810 is not set -CONFIG_DRM_I830=y -# CONFIG_DRM_I915 is not set +CONFIG_DRM_I810=y +# CONFIG_DRM_I830 is not set +CONFIG_DRM_I915=y +# CONFIG_DRM_I915_KMS is not set # CONFIG_DRM_MGA is not set # CONFIG_DRM_SIS is not set # CONFIG_DRM_VIA is not set # CONFIG_DRM_SAVAGE is not set # CONFIG_VGASTATE is not set CONFIG_VIDEO_OUTPUT_CONTROL=y -# CONFIG_FB is not set +CONFIG_FB=y +CONFIG_FIRMWARE_EDID=y +CONFIG_FB_DDC=y +CONFIG_FB_BOOT_VESA_SUPPORT=y +CONFIG_FB_CFB_FILLRECT=y +CONFIG_FB_CFB_COPYAREA=y +CONFIG_FB_CFB_IMAGEBLIT=y +CONFIG_FB_MODE_HELPERS=y +CONFIG_FB_VESA=y +CONFIG_FB_INTEL=y +CONFIG_FB_INTEL_I2C=y And, now X also echos something new to the Xorg.0.log: (II) intel(0): I2C device "LVDSDDC_C:ddc2" registered at address 0xA0. (II) intel(0): I2C device "LVDSDDC_C:ddc2" removed. So I assume that it has something to do either with CONFIG_FB_INTEL_I2C or CONFIG_FB_DDC. But why on earth did that all work out of the box on 2.6.28? Hope that helps to explain these problems, and someone else finds a proper solution. Thanks (BTW I don't consider that fixed,probably anyone having CONFIG_FB disabled in 2.6.28 will have that problem, loosing i915 drm and brightness adjustment) -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------------ This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
