Hi,
Looks like you are using the wrong intel driver.
For intel modesetting you need CONFIG_DRM=y CONFIG_DRM_KMS_HELPER=y # 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 is not set CONFIG_DRM_I915=y # CONFIG_DRM_I915_KMS is not set
CONFIG_DRM_I915_KMS=y needed as well?
# 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_FB_I810 is not set
That will give you inteldrmfb. ^^^
Not sure what dependency is missing in your config that DRM_I915 does not show up... (it might be CONFIG_AGP_INTEL)
intelfb (CONFIG_FB_I810) is obsolete and only supports a pretty limited part of intel GPU features, modesetting only for VGA output (and not sure it works at all with recent GPUs).

Hi!
I'm trying to fix up my kernel setup so that X is happy... currently it fails to start with:
FATAL: Could not load /lib/modules/2.6.37-rc5+/modules.dep: No such file or directory (EE) intel(0): No kernel modesetting driver detected. (EE) Screen(s) found, but none have a usable configuration.
So far I have:
CONFIG_DRM=y # 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_MGA is not set # CONFIG_DRM_SIS is not set # CONFIG_DRM_VIA is not set # CONFIG_DRM_SAVAGE is not set # CONFIG_STUB_POULSBO is not set CONFIG_VGASTATE=y CONFIG_VIDEO_OUTPUT_CONTROL=y CONFIG_FB=y CONFIG_FB_I810=y # CONFIG_FB_I810_GTF is not set # CONFIG_FB_LE80578 is not set CONFIG_FB_INTEL=y CONFIG_FB_INTEL_DEBUG=y CONFIG_FB_INTEL_I2C=y # CONFIG_FB_MATROX is not set
And on the command line:
BOOT_IMAGE=(hd0,2)/l/linux-good/arch/i386/boot/bzImage root=/dev/sda4 resume=/dev/sda1 psmouse.psmouse_proto=imps psmouse_proto=imps psmouse.proto=imps vga=791 init=/tmp/swsusp-init acpi_sleep=s3_bios,s3_mode no_console_suspend i915.modeset=1 video=intelfb:mode=1024x768 fbcon=scrollback:64k
...but intelfb fails with:

Any hints? If I'm doing some trivial mistake, perhaps "cannot reserve FB region" message could be improved? Pavel
