Comment 43 for bug 54858

after installing the mesa libgl1 packages from above I got these errors:

(II) LoadModule: "dri"
(II) Loading /usr/lib/xorg/modules/extensions/libdri.so
(II) Module dri: vendor="X.Org Foundation"
 compiled for 7.1.1, module version = 1.0.0

(EE) Failed to load module "dri" (a required submodule could not be loaded, 6)
(II) LoadModule: "extmod"
(II) Loading /usr/lib/xorg/modules/extensions/libextmod.so

(see full log attached for more)

A few things to keep in mind:

Edgy system (up-to-date) using kernel from Dapper (current stable kernel)

$> ls /lib/modules/2.6.15-26-686/volatile/
ath_hal.ko fcdslusb2.ko fcusb.ko mach64.ko r128.ko
drm.ko fcdslusba.ko fglrx.ko mga.ko radeon.ko
fcdsl2.ko fcdslusb.ko fxusb.ko new_ath_hal.ko savage.ko
fcdsl.ko fcpci.ko i810.ko nvidia.ko sis.ko
fcdslsl.ko fcpcmcia_cs.ko i830.ko nvidia_legacy.ko tdfx.ko
fcdslslusb.ko fcpcmcia.ko i915.ko nv.ko via.ko

drm and i810 kernel drivers come from package:

$> dpkg -S /lib/linux-dri-modules/2.6.15-26-686/i810.ko
linux-dri-modules-2.6.15-26-686: /lib/linux-dri-modules/2.6.15-26-686/i810.ko

Which in turn comes from:

I removed the i810 driver from the kernel so that volatile takes over...
Let me do the same for drm.ko
