intelfb refuses to load

[Pavel Machek]

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

acpi_sleep=s3_bios,s3_mode no_console_suspend i915.modeset=1
video=intelfb:mode\x1024x768 fbcon=scrollback:64k

...but intelfb fails with:

Any hints? If I'm doing some trivial mistake, perhaps "cannot reserve

Re: intelfb refuses to load

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_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intelfb (CONFIG_FB_I810) is obsolete and only supports a pretty limited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).

It is hidden by "choice" with interesting name.

Unfrotunately, if I do this, I get kernel messages for about a second,
and then blank screen. Thinkpad X60...

I now have:

i915.modeset=1 video=inteldrmfb:mode\x1024x768 fbcon=scrollback:64k 

on cmdline and:

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_MGA is not set
# CONFIG_DRM_SIS is not set
# CONFIG_DRM_VIA is not set
# CONFIG_DRM_SAVAGE is not set

CONFIG_VGASTATE=y
CONFIG_VIDEO_OUTPUT_CONTROL=y
CONFIG_FB=y

# CONFIG_FB_DDC is not set
...

Perhaps something like this should be done? I had no idea that the
choice is for modern drivers, too...

CONFIG_FRAMEBUFFER_CONSOLE?

No, that one was set. (I see even two penguins for a short while).

#
# Console display driver support
#
CONFIG_VGA_CONSOLE=y
# CONFIG_VGACON_SOFT_SCROLLBACK is not set
CONFIG_DUMMY_CONSOLE=y
CONFIG_FRAMEBUFFER_CONSOLE=y
# CONFIG_FRAMEBUFFER_CONSOLE_DETECT_PRIMARY is not set

CONFIG_DRM_I915_KMS=y needed as well?
