X - Cant find/load module!

hi,
just set up my new system. no problems occured at first.
then i installed xorg, tested -> worked.
now i got xfce as Desktop-Environment.
after that i tried: startx, and he responded 2 errors:
1) 
 

....
  FATAL: Module i810 not found.
  (EE) [drm] drmOpen failed.
  (EE) intel(0): [dri] DRIScreenInit failed. DIsabling DRI.
  ....

2)
 

 ~/.xinitrc: line 18: exec: ck-launch-session: not found
  xinit: connection to X server lost

well the second one isnt fatal (acc. to error-report )
so my question is, why does it search for the i810 module?
lsmod gives: i915..... but i dont need the i915 module, do i?
anyone an idea what to do next?

lg

Add: i use the i815 chipset and installed the xf86-video-intel driver which should supports the i810+ chipsets

Re: X - Cant find/load module!

1.
You are right, your module should be in the "xf86-video-intel" package. What does

modprobe i810

give you as output?

The drivers for the i915 and i810 are also in the kernel and there is a note at the "i915" one saying:

Note that the older i810/i815 chipsets require the use of the
i810 driver instead, and the Atom z5xx series has an entirely
different implementation.

Unfortunately the "i810" module doesn't come with the default arch kernel since this module requires "PREEMPT [=n]" which is false at the default kernel, so you have to rely on the xf86-video-intel package (and just a guess: maybe you can't load it because PREEMPT is set to "y" in the arch kernel, but let's look what modprobe says...).

2.
For this one install "consolekit".

//Edit:
Forget what I sait at point 1, the xf86 packages just provide userspace driver, but in order to work properly they need the appropriate kernelspace driver which is "i810" in your case. As I wrote "i810" is not distributed with the default kernel, so I guess you have to recompile the kernel just change

-> Processor type and features
-> Preemption Model"

to "Voluntary Kernel Preemption (Desktop)"
and then enable

-> Device Drivers
-> Graphics support
-> Direct Rendering Manager
-> Intel I810 (DRM_I810)

Then you should be able to use your antique graphics card
Since your xorg-test worked fine I guess xorg just used the fallback vesa mode, which should work with xfce, too without recompiling of course - but it is slow. Make sure that you have "xf86-video-vesa" installed if you want to use this "fallback" mode.
