I have built a working X Window System from (B)LFS 7.8 on desktop 1.
I copied the whole system to a laptop and it worked there all-right.
I copied that same system to another desktop (2), but there the X-system did
not work. Outpot from Xorg.0.log:
[ 27.148] (II) Loading /usr/lib/xorg/modules/drivers/nouveau_drv.so
[ 27.193] (EE) [drm] KMS not enabled
[ 27.193] (EE) No devices detected.
The main difference between the systems: desktop 1 and the laptop have Intel
graphics-chips, desktop 2 NVIDIA (output from lspci:
01:00.0 VGA compatible controller: NVIDIA Corporation NV5 [Riva TNT2 Model
64 / Model 64 Pro] (rev 15))
DRM_NOUVEAU should be set (it looks like the main enabler, depends
on various things, in menuconfig use '/DRM_NOUVEAU' if you cannot
enable it). In fact, it looks to me as if that is the only thing
which requires to be set to build nouveau in the kernel.
DRM_NOUVEAUis build into the kernel.
There is also NOUVEAU_PLATFORM_DRIVER if this is a SoC (System on
Chip) - but I guess that the RIVA TNT2 is NOT a SoC because the
concept seems to be fairly recent. Google suggests it is Tegra and
newer : I believe those are for ARM not x86.
If DRM_NOUVEAU is enabled: is it a module ?
No.
Beyond that, perhaps FRAMEBUFFER_CONSOLE needs to be set ?
Is set in the kernel.
The only references to KMS in _my_ (ATI) config are DRM_KMS_HELPER
and DRM_KMS_FB_HELPER - the first of those is, for me, selected
(i.e. turned on automatically) by HAS_IOMEM && DRM, and the second
for you would be selected by DRM_NOUVEAU.
DRM_KMS_HELPER and DRM_KMS_FB_HELPER are set in the kernel.

Can you help me to understand what "[drm] KMS not enabled" means?
Hans.
