After installing Arch on my Thinkpad Edge 14 everything works out of the box except Xorg.
[ 126.836] (EE) intel(0): unrecognized backlight control interface (null)
- backlight control interface which is located at /sys/class/backlight/intel_backlight
But the server still tries to use acpi_video0
Ensure CONFIG_DRM and CONFIG_DRM_I915 are set in your kernel config, and install xf86-video-intel (or set VIDEO_CARDS="intel" in /etc/make.conf) to get X.org to recognise the video card.
I did # pacman -S xf86-video-intel
I'm not sure how to do the other stuff... (noob)
Would appreciate any help,
lowly
p.s. I also have some font warnings in the same log file, but hopefully that's trivial.

The HP g6's and g7's needed the following added to the kernel line to work:
acpi_osi=Linux acpi_backlight=vendor
I was getting the same message as you as I was building my new laptop yesterday. The "unrecognized backlight control" was fixed with the above additions. YMMV since it's not an HP, but it might be a start.
Also, I had NO xorg.conf or ANYTHING set. I just added i915 and intel_agp to the modules line as directed in the Wiki article no Intel cards.

Where exactly do i put 'acpi_osi=Linux acpi_backlight=vendor'?
I'm using syslinux
Edit: just typed it into the command line. Nothing happend so i assume that's it. Still same error after reboot.
I just did the following according to the wiki.
MODULES="i915 intel_agp"
then,
# mkinitcpio -p linux
then reboot.
Still same error.

Please see http://cgit.freedesktop.org/xorg/driver … af71b985ed and man 4 intel. Basically, the error seems to be spurious as it only means that no user-defined backlight is found. This is a new feature in xf86-video-intel 2.20.6 (before there was no such error). To summarize, regarding the backlight, you don't have to do anything. It is not the reason why your Xorg doesn't work...

Those are irrelevant. Post your Xorg.0.log and output of startx when it fails.
Arch Linux is more than just GNU/Linux -- it's an adventure

(WW) Open ACPI failed (/var/run/acpid.socket) (No such file or directory)
(WW) Falling back to old probe method for vesa
(WW) Falling back to old probe method for fbdev
I fixed the ACPI error with this thread.
As for the others, well I installed xterm & xclock:
#pacman -S xterm
and
#pacman -S xorg-xclock
I like this...
